(c) 2007 SanDisk(R) Corporation 12 92-DS-1205-10 Product Overview mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 2. PRODUCT OVERVIEW 2.1 Product Description mDOC H3 is the latest addition to SanDisk's mDOC product family. mDOC H3, packaged in a small FBGA package and offering densities ranging from 1Gb (128MB) to 16Gb (2GB), is a hybrid device with an embedded flash controller and high capacity flash memory. It uses advanced Flash technologies, enhanced by SanDisk's proprietary TrueFFS embedded flash management software. All mDOC H3 devices are ball to ball compatible. The replacement of one mDOC H3 device with another of a newer generation requires virtually no changes to the host. This makes mDOC H3 the perfect solution for platforms and reference designs, as it allows for the utilization of more advanced NAND Flash technology and new mDOC functionality with minimal integration efforts. mDOC H3 has a 32KB Programmable Boot Block. This block provides eXecute In Place (XIP) functionality, enabling mDOC H3 to replace the boot device and to function as the only non-volatile memory device on-board. Eliminating the need for an additional boot device reduces hardware expenditures, board real estate, programming time, and logistics. The Paged RAM IPL feature separates the Boot Block into sections: The first section provides constant data, while the other sections (up to 254KB) can be loaded with data that is automatically downloaded from the flash. One application of this feature is to support processors' secure boot requirements. Sandisk's proprietary TrueFFS flash management software overcomes NAND-related error patterns by using a robust error detection and correction (EDC/ECC) mechanism. Furthermore, it provides performance enhancements such as multi-plane operations, DMA support, Burst operation and Dual Data RAM buffering. The new generation of patented flash management software, Embedded TrueFFS, is run on the embedded thin controller of the mDOC H3 device, instead of on the host. This results in improvements in performance, ease of integration and overall utilization of latest NAND technologies. Embedded TrueFFS guarantees high reliability and isolates all the complexity of flash management from the host SW. Embedded TrueFFS enables mDOC H3 to fully emulate a hard disk to the host processor, enabling read/write operations that are identical to a standard, sector-based hard drive. In addition, Embedded TrueFFS employs patented methods, such as virtual mapping, dynamic and static wear-leveling, and automatic bad block management to ensure high data reliability and maximize flash life expectancy. mDOC H3 extended features are enabled by a small driver that runs on the host side, called DOC Driver. DOC Driver provides the host O/S with a standard Block Device interface, together with APIs for mDOC H3's extended features. The combination of Embedded TrueFFS and DOC Driver practically enables Plug and Play integration. mDOC H3 offers extended content protection and security-enabling features. Up to 14 write protected, read-and-write protected, or One Time Programmable (OTP) partitions can be configured independently for maximum design flexibility. A 16-byte Unique ID (UID) identifies each device, eliminating the need for a separate ID device on the motherboard. The combination 13 92-DS-1205-10 Product Overview mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 of these features enables mDOC H3 to implement better security schemes to protect the code and data it stores. mDOC H3 can be configured to work with either demux (standard) interface or multiplexed (MUX) interface. Using a multiplexed interface where data and address lines are multiplexed on the same lines, reduces the number of signals required to connect mDOC H3 to the CPU. The combination of unique H3 design, latest NAND technology and Embedded TrueFFS results in a low-cost, minimal-sized flash disk that achieves unsurpassed reliability levels, enhanced performance and ease of integration. This breakthrough in performance, size, cost and design makes mDOC H3 the ideal solution for mobile handsets and consumer electronics manufacturers who require easy integration, fast time to market, high-capacity, small size, high-performance and, above all, high-reliability storage to enable multimedia driven applications such as music, photo, video, TV, GPS, games, email, office and other applications. mDOC H3 offers advanced power consumption management throughout the selection of different operating modes. The operating modes of the mDOC H3 device are designed to be easily controlled by the chipset and DOC Driver to ensure optimal battery life in mobile devices. mDOC H3 can be placed in any of the following four operating modes: * Turbo mode - While in Turbo mode, device internal clocks are optimized for maximal performance. * Power Save mode - While in Power Save mode, device internal clocks are optimized to balance between device performance and power consumption. * Standby mode - While in Standby mode, the clock of most internal cores is either disconnected or reduced to a minimum. There is no wake-up time penalty. * Deep Power Down (DPD) mode - While in Deep Power-Down mode, device quiescent power dissipation is reduced by disabling internal high current consumers (e.g. flash, voltage regulators, input buffers, oscillator etc.) The power management flexibility of mDOC H3 allows for the system designers to substantially reduce the power consumption of the mDOC device, based on the requirements of the mobile device, to effectively and considerably prolong battery life. 2.2 Demux (Standard) Interface 2.2.1 9x12/10x14/12x18 FBGA Ball Diagrams Figure 2 shows the mDOC H3 115 ball demux interface ball diagram. To ensure proper device functionality, balls marked RSRVD are reserved for future use and should be connected as described in Table 1, Section 2.2.2.

Figure 5: Multiplexed Interface Simplified I/O Diagram 24 92-DS-1205-10 Theory of Operation mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 3. THEORY OF OPERATION 3.1 Overview mDOC H3 consists of the following major functional blocks, as shown in Figure 6. Figure 6: Simplified Block Diagram These components are described briefly below and in more detail in the following sections. * Host IF - Host physical interface block. Includes the following interfaces: Demux (Standard), Multiplexed, and Serial. * Host Agent - Logical host interface supporting the host protocol and Programmable Boot Block with XIP functionality. * Flash Partition Management - High level management of the Flash media, managing flash logical partitions, and their attributes. * Flash BD Management - Management of the Flash media at a Block Device level, primarily performing logical to physical address translation. * Boot Agent - Management of host boot sequence - Loading of Boot code from flash media upon power up. * ECC / EDC - Error Detection and Error Correction Codes (EDC/ECC) - On-the-fly Flash error handling. * Data Buffer - 4KB Dual-Port RAM memory, used as a pipeline buffer, for enhanced data transfer rate. * Flash Agent - Provides High level Flash management functions and sequences for Flash control and error condition handling. 25 92-DS-1205-10 Theory of Operation mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 * * * Flash IF - Physical interface to the Flash Media. Power and Timing - Analog and clock circuits to provide power and timing for the H3 controller and flash. Embedded CPU - Runs Embedded TrueFFS SW and mDOC H3 controller firmware. 3.2 Host Interface 3.2.1 Demux (NOR-Like) Interface The host interface block provides an easy-to-integrate NOR-like (also SRAM and EEPROMlike) interface to mDOC H3, enabling various CPU interfaces, such as a local bus, ISA bus, NOR interface, SRAM interface, EEPROM interface or any other compatible interface. In addition, the NOR-like interface enables direct access to the Programmable Boot Block to permit XIP (Execute-In-Place) functionality during system initialization. A1-A16 address lines enable access to the mDOC H3 128KB memory window. When migrating from mDOC G3/G4/H1 without changing the PCB, thus using only A1-A12 address lines, mDOC H3 exports 8KB memory window, like in mDOC G3/G4 and H1. The Chip Enable (CE#), Write Enable (WE#) and Output Enable (OE#) signals trigger read and write cycles. A write cycle occurs while both the CE# and the WE# inputs are asserted. Similarly, a read cycle occurs while both the CE# and OE# inputs are asserted. Note that mDOC H3 does not require a clock signal. The CE#, WE# and OE# signals trigger the controller (e.g., system interface block, bus control and data pipeline) and flash access. The Reset-In (RSTIN#) and Busy (BUSY#) control signals are used in the reset phase. The Interrupt Request (IRQ#) signal is used to indicate completion of assorted operations. Using this signal frees the CPU to run other tasks, continuing read/write operations with mDOC H3 only after the IRQ# signal has been asserted and an interrupt handling routine (implemented in the OS) has been called to return control to the DOC Driver. The DMARQ# output is used to control DMA operations, and the CLK input is used to support Burst operation when reading flash data. See Section 10.3 for further information. 3.2.2 Multiplexed Interface In this configuration, the address and data signals are multiplexed. The AVD# input is driven by the host AVD# signal, and the D[15:0] signals, used for both address inputs and data, are connected to the host AD[15:0] bus. While AVD# is asserted, the host drives AD[15:0] with bits [16:1] of the address. This interface is automatically used when a falling edge is detected on AVD#. This edge must occur after RSTIN# is de-asserted and before the first read or write cycle to the controller. 26 92-DS-1205-10 Theory of Operation mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 3.2.3 Serial Interface The Serial interface (SPI) provides mDOC H3 a secondary interface with debug and programming capabilities. mDOC H3 SPI Interface is configured as Slave. All four combinations of clock phase (CPHA) and clock polarity (CPOL) which are defined by the SPI specification are supported. The Serial interface supports two usage scenarios: 1. Debug port: Allowing the host with an SPI interface to read debug messages. 2. Format and Program port: Allowing a programmer to use this port in order to format and program the device. The serial protocol debug port provides a means for the serial interface (SPI Slave) to queue and transmit debug messages to a host equipped with an SPI interface. All transfers are performed in multiples of 8 bits, with the MSB of each byte transmitted first. 3.3 Host Agent 3.3.1 Host Protocol Block of registers and logic required for implementing block device operations over the host interface. This block implements a set of complex transactions required for operating the mDOC H3 device. These transactions include data storage operations as well as device configuration and management. 3.3.2 Boot Block (XIP) The Programmable Boot Block with XIP functionality enables mDOC H3 to act as a boot device (in addition to performing flash disk data storage functions). This eliminates the need for expensive, legacy NOR flash or any other boot device on the motherboard. The Programmable Boot Block is 32KB in size. The Boot Agent, described in the next section, is responsible for copying the boot code/data from the flash into the boot block. 3.4 Boot Agent Upon power-up or when the RSTIN# signal is de-asserted, the Boot Agent automatically downloads the Initial Program Loader (IPL) to the Programmable Boot Block. The IPL contains the code for starting the Host boot process. The download process is quick, and is designed so that when the CPU accesses mDOC H3 for code execution, the IPL code is already located in the Programmable Boot Block. During the download process, mDOC H3 does not respond to read or write accesses. Host systems must therefore observe the requirements described in Section 10.3.12. During the download process, mDOC H3 asserts the BUSY# signal to indicate to the system that it is not yet ready to be accessed. Once BUSY# is de-asserted, the system can access mDOC H3. Note that after IPL is loaded and BUSY# is de-asserted, the Boot Agent continues to download the embedded TrueFFS from Flash to the mDOC H3 internal RAM, and then executes it. Downloading the embedded TrueFFS is done in parallel to the host system accessing the IPL 27 92-DS-1205-10 Theory of Operation mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 code. During the time between BUSY# signal de-assertion and completing the download of Embedded TrueFFS, mDOC H3 will respond only to accesses to the XIP Boot Block (including Paged RAM accesses) in order to facilitate completion of the IPL execution. Once Embedded TrueFFS is loaded, executed and has completed its media mount process, mDOC H3 is ready to be used as a fully functional storage device. 3.5 Error Detection Code/Error Correction Code (EDC/ECC) Since NAND-based flash is prone to errors, it requires unique error-handling capabilities to ensure required reliability. SanDisk's TrueFFS technology, embedded within mDOC H3, includes a powerful Error Detection Code / Error Correction Code (EDC/ECC), based on the Bose, Chaudhuri and Hocquenghem (BCH) algorithm. Both EDC and ECC are implemented in hardware to optimize performance. Each time a 512-byte sector is written, additional parity bits are calculated and written to the flash. Each time data is read from the flash, the parity bits are read and used for calculating error locations. It ensures that the minimal amount of code is used for detection and correction to deliver the required reliability without degrading performance. 3.6 Block Device Management Block device management is performed by an embedded SW module, responsible for execution of all Block Device operations, such as address calculation, erase, read and writes operations etc. This module translates these operations from virtual media terms (i.e. sector addresses) to flash media terms (i.e. flash planes, blocks and pages). These Block Device operations are typically initiated by the host File System, translated by the DOC Driver and sent to the device over the host interface. The Host Agent (above) is responsible for capture and transfer to the Block Device management. 28 92-DS-1205-10 Data Protection and Security-Enabling features mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 4. DATA PROTECTION AND SECURITY-ENABLING FEATURES 4.1.1 Read/Write-Protected partitions Data and code protection is implemented on a per-partition basis. The user can configure each partition as read protected, write protected, or read and write protected. A protected partition may be protected by either/both of these mechanisms: * Up to 64 bit protection key * Hard-wired LOCK# signal * Sticky lock (SLOCK) In order to set or remove read/write protection, the protection key must be used as follows: * Insert the protection key to remove read/write protection * Remove the protection key to set read/write protection The only way to read or write from/to a partition that is protected against read or write, is to insert the key. This is also true for modifying its attributes (protection key, read, write and lock). Read/write access is disabled (the key is automatically removed) in each of the following events: * Power-down * Removal of the protection key For further information on protection, please refer to the DOC Driver 1.0 Block Device (BD) Software Development Kit (SDK) developer guide. 4.1.2 LOCK# signal mDOC H3 has an additional hardware safety measure. If the Lock option is enabled for a specific partition, and the LOCK# signal is asserted, the protected partition has an additional hardware lock that prevents read/write access to the partition, even with the use of the correct protection key. 4.1.3 Sticky Lock (SLOCK) It is possible to set the Lock protection for one session only; that is, until the next power-up or reset. This Sticky Lock feature can be useful when the boot code in the boot partition must be read/write protected. Upon power-up, the boot code must be unprotected so the CPU can run it directly from mDOC H3. At the end of the boot process, protection can be set until the next power-up or reset. This is done by setting the Sticky Lock (SLOCK) bit in the Software Lock register, or using a dedicated S/W API, and has the same effect as asserting the LOCK# signal. Once set, SLOCK can only be cleared by asserting the RSTIN# input. Like the LOCK# input, assertion of this bit prevents the protection key from disabling the protection for a given partition. There is no need to mount the partition prior to this operation. 29 92-DS-1205-10 Data Protection and Security-Enabling features mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 4.1.4 Unique Identification (UID) Number Each mDOC H3 is assigned a 16-byte UID number. Burned onto the flash during production, the UID cannot be altered and is worldwide unique. The UID is essential for security-related applications, and can be used to identify end-user products in order to fight fraudulent duplication by imitators. 4.1.5 One-Time Programmable (OTP) Partitions OTP feature is implemented on a per-partition basis, for full flexibility. Once a partition has been defined as OTP (upon initial media-formatting), it can be written only once, after which it is automatically and permanently locked. After it is locked, the OTP partition becomes read only, just like a ROM device. Regardless of the state of any of the LOCK options, OTP partitions cannot be erased. Typically, the OTP partition is used to store customer and product information such as: product ID, software version, production data, customer ID, PKI keys, service provider information and tracking information. 30 92-DS-1205-10 mDOC H3 Modes of Operation mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 5. MDOC H3 MODES OF OPERATION Figure 7 shows the different modes of mDOC H3 device operation and the interchange between optional modes. mDOC H3 can operate in any one of five basic power modes/states: * Reset state * Turbo mode * Power save mode * Standby mode * Deep Power-Down mode Figure 7: Operation Modes State Machine 31 92-DS-1205-10 mDOC H3 Modes of Operation mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 The above power modes are separated into two main groups: * Work mode group - in which the device is active and performs various transactions. * Idle mode group - in which the device is not active. The power mode is determined as follows: * Assertion of the RSTIN# signal sets the device in Reset state. * Upon power up the device enters its pre-configured work mode. * Default work mode is Turbo mode. The default can be changed to PowerSave mode and vice-versa using S/W API. * Once in any idle mode the device will move to work mode upon any transaction. It may return to idle mode upon inactivity, if so configured. * Entry and exit to/from Deep Power-Down mode is described below. 5.1 Reset State While in Reset State, mDOC H3 ignores all write transactions and returns undefined values in response to any read access. 5.2 Turbo Mode This mode is defined as a "work mode" and is optimized for performance. All internal clocks are set to maximal work frequency. In this mode all standard operations involving the flash memory can be performed. 5.3 Power Save Mode This mode is defined as a "work mode" and is optimized for balance between power consumption and performance. Balance is achieved by setting internal clocks to predefined optimal settings. In this mode all standard operations involving the flash memory can be performed. 5.4 Standby Mode mDOC H3 enters standby mode upon device inactivity. In Standby mode the clock of most internal cores is either disconnected or reduced to a minimum. There is no wake-up time penalty when switching back to working mode. 32 92-DS-1205-10 mDOC H3 Modes of Operation mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 5.5 Deep Power-Down Mode While in Deep Power-Down (DPD) mode, the quiescent power dissipation of the mDOC H3 device is further reduced by disabling internal high current consumers (e.g. voltage regulators, input buffers, oscillator etc.) Entering Deep Power-Down mode is done by either of the following: * Writing to POWER_DN bit in the Power Mode Register. * Activating a SW API to put the device immediately in DPD. * Setting Auto DPD mode by SW. Depending on Auto DPD mode chosen the device will either enter DPD upon device inactivity, or enter Standby mode upon device inactivity and switch to DPD after a configurable period of inactivity. Entering Deep Power-Down mode and then returning to the previous mode does not affect the value of any register. Exiting Deep Power-Down mode is done using one of the following methods: * Performing a read/write access from/to mDOC H3. * RSTIN# assertion. 33 92-DS-1205-10 Embedded TrueFFS Technology mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 6. EMBEDDED TRUEFFS TECHNOLOGY 6.1 General Description SanDisk's patented TrueFFS technology was designed to maximize the benefits of flash memory while overcoming inherent flash limitations that would otherwise reduce its performance, reliability and lifetime. TrueFFS emulates a hard disk making flash transactions completely transparent to the OS. In addition, since DOC Driver operates under the OS file system layer, and exports standard Block Device API, it is completely transparent to the application. TrueFFS is now embedded within the mDOC H3 device, eliminating the need for complicated software integrations and enabling a practically Plug & Play integration with the system. mDOC H3 with Embedded TrueFFS handles all the complexity of flash management for the host SW. This dramatically simplifies software integration and test. It also allows for cost reductions to be achieved in projects using mDOC by upgrading to newer generations of mDOC devices based on newer and more cost effective NAND technologies. The embedded flash management offered by TrueFFS assures that software on the host system or mass production tools need not to be changed or re-qualified when flash technology is changed. mDOC SW support includes: * Drivers support for all major OSs * DOC Driver Software Development Kit (DOC Driver SDK) * TrueFFS 7.1 Software Development Kit (TrueFFS 7.1 SDK) - One SW package to support both earlier mDOC technologies (such as G3, G4 and H1) and mDOC H3. * Support for all major CPUs, including 16 and 32-bit bus architectures Embedded TrueFFS technology features: * Flash management * Bad-block management * Dynamic virtual mapping * Dynamic and static wear-leveling * Power failure management * Implementation of EDC/ECC * Performance optimization 6.2 Operating System Support The DOC Driver is integrated into all major OSs, including Symbian, Microsoft Windows Mobile, Windows CE, Linux and others. For a complete listing of all available drivers, please contact your local SanDisk sales office or distributor. 34 92-DS-1205-10 Embedded TrueFFS Technology mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 6.3 DOC Driver Software Development Kit (SDK) DOC Driver Software Development Kit (SDK) provides the source code for the DOC Driver. It can be used in an OS-less environment or when special customization of the driver is required for proprietary OSs. The DOC Driver SDK is used also for utilizing mDOC H3 as the boot device. TrueFFS 7.1 Software Development Kit (TrueFFS 7.1 SDK) provides the DOC Driver code, bundled with the TrueFFS code needed to support earlier mDOC technologies (such as G3, G4 and H1) as well. 6.3.1 File Management DOC Driver accesses the flash memory within mDOC H3 through either 8KB or 128KB window in the CPU memory space, depending on the mDOC H3 configuration. DOC Driver provides block device API by using standard file system calls, identical to those used for a hard disk, to enable reading from and writing to mDOC H3. This makes mDOC H3 compatible with any file system and file system utilities, such as diagnostic tools and applications. Note: mDOC H3 is shipped unformatted and contains virgin media. 6.3.2 Bad-Block Management Since NAND flash is an imperfect storage media, it can contain bad blocks that cannot be used for storage because of their high error rates. Embedded TrueFFS automatically detects and maps out bad blocks upon system initialization, ensuring that they are not used for storage. During runtime, if additional bad blocks are detected they are automatically retired and replaced by blocks that are located in a pool of spares. This management process is completely transparent to the user, who is unaware of the existence and location of bad blocks, while remaining confident of the integrity of data stored. 6.3.3 Wear-Leveling Flash memory can be erased a limited number of times. This number is called the erase cycle limit, or write endurance limit, and is defined by the flash device vendor. The erase cycle limit applies to each individual erase block in the flash device. In a typical application, and especially if a file system is used, specific pages are constantly updated (e.g., the pages that contain the FAT, registry, etc.). Without any special handling, these pages would wear out more rapidly than other pages, reducing the lifetime of the entire flash. To overcome this inherent deficiency, Embedded TrueFFS uses SanDisk's patented wearleveling algorithm. This wear-leveling algorithm ensures that consecutive writes of a specific sector are not written physically to the same page in the flash. This spreads flash media usage evenly across all pages, thereby maximizing flash lifetime. Dynamic Wear-Leveling Embedded TrueFFS uses statistical allocation to perform dynamic wear-leveling on newly written data. This means that new data will be written to flash units which are less worn out. 35 92-DS-1205-10 Embedded TrueFFS Technology mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 Static Wear-Leveling Areas on the flash media may contain static files, characterized by blocks of data that remain unchanged for very long periods of time, or even for the whole device lifetime. If wear-leveling were only applied on newly written pages, static areas would never be cycled. This limited application of wear-leveling would lower life expectancy significantly in cases where flash memory contains large static areas. To overcome this problem, Embedded TrueFFS forces data transfer in static areas as well as in dynamic areas, thereby applying wear-leveling to the entire media. 6.3.4 Power Failure Management Embedded TrueFFS uses algorithms based on "erase after write" instead of "erase before write" to ensure data integrity during normal operation and in the event of a power failure. Used areas are reclaimed for erasing and writing the flash management information into them only after an operation is complete. This procedure serves as a check on data integrity. The "erase after write" algorithm is also used to update and store mapping information on the flash memory. This keeps the mapping information coherent even during power failures. The only mapping information held in RAM is a table pointing to the location of the actual mapping information. This table is reconstructed during power-up or after reset from the information stored in the flash memory. To prevent data from being lost or corrupted, Embedded TrueFFS uses the following mechanisms: * When writing, copying, or erasing the flash device, the data format remains valid at all intermediate stages. Previous data is never erased until the operation has been completed and the new data has been verified. * A data sector cannot exist in a partially written state. The operation is either successfully completed, in which case the new sector contents are valid, or the operation has not yet been completed or has failed, in which case the old sector contents remain valid. In addition, Embedded TrueFFS applies a unique algorithm to ensure that new data written to the device will not affect any data already programmed to the device. 6.3.5 Error Detection/Correction Embedded TrueFFS implements a unique Error Correction Code (ECC) algorithm to ensure data reliability. Refer to Section 3.5 for further information on the EDC/ECC mechanism. 6.3.6 Special Features through I/O Control (IOCTL) Mechanism In addition to standard storage device functionality, the DOC Driver provides extended functionality. This functionality goes beyond simple data storage capabilities to include features such as: formatting the media, read/write protection, boot partition(s) access and other options. This unique functionality is available in all DOC Drivers through the standard I/O control command of the native file system. 36 92-DS-1205-10 Embedded TrueFFS Technology mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 6.3.7 Compatibility Migrating from mDOC G3/G4/H1 and mDOC G3/G4 -based MCP to mDOC H3 and mDOC H3 -based MCP can be done by TrueFFS 7.1. TrueFFS 7.1 supports all mDOC product line including mDOC G3/G4/H1 and mDOC H3. DOC Driver 1.0 and higher provides stand alone SW support for mDOC H3 only. It does not support mDOC G3/G4 and H1. When using different software modules (e.g. Block Device DOC Driver, Boot application, formatting utilities, etc.) to access mDOC H3 it is crucial to verify that all software modules are based on the same code base version. It is also important to use only tools (e.g. DFORMAT, DINFO, DIMAGE, etc.) from the same version as the DOC Drivers used by the application. Failure to do so may lead to unexpected results, such as lost or corrupted data. The driver version can be verified by the sign-on messages displayed, or by the version information presented by the driver or tool. 6.4 128KB Memory Window mDOC H3 utilizes a 128KB memory window in the CPU address space, consisting of four 32KB sections as depicted in Figure 8. The addresses described here are relative to the absolute starting address of the 128KB memory window. The 32KB Programmable Boot Block (XIP) is aliased to section 0, 2 and 3. The sections are aligned to addresses 00000H, 10000H and 18000H additionally the second half of section 1 contains the second half of the IPL. This is done in order to enable additional flexibility in the IPL addressing schemes. For compatibility with next generation mDOC H3 devices, it is recommended to use only 8KB of the 32KB Programmable Boot Block. Address 8000H + offset is the base address for the mDOC H3 registers used for communication with the mDOC H3 device (excluding the Paged RAM Registers). 37 92-DS-1205-10 Embedded TrueFFS Technology mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 128K window 00000h Section 0 IPL RAM (Host XIP) 32K / 4 X 8K 08000h Section 1 H3 Registers 16K IPL RAM - Upper Area (Host XIP) 16K 0C000h 10000h Section 2 IPL RAM Alias (Host XIP) 32K / 4 X 8K 18000h Section 3 IPL RAM Alias (Host XIP) 32K / 4 X 8K 1FFFFh Figure 8: mDOC H3 128KB Memory Map Note: In future mDOC H3, IPL RAM size is 8KB.

BOOTING FROM MDOC H3 8.1 Introduction mDOC H3 can function both as a flash disk and as the system boot device. If mDOC H3 is used both as a flash disk and as the system boot device, it contains the boot loader, an OS image and a file system. In such a configuration, mDOC H3 can serve as the only non-volatile device on board. When using mDOC H3 as the system boot device, the CPU fetches the first instructions from the mDOC H3 Programmable Boot Block, which contains the IPL. The IPL handles the required platform initializations, and then loads the required image or OS Boot loader from its dedicated partition. SanDisk's DOC Driver, SDK and utilities enable the construction of a proper mDOC H3 layout in order to support the boot sequence. For a complete description of these tools, refer to the DOC Driver 1.0 Block Device (BD) Software Development Kit (SDK) developer guide and the DOC Driver 1.0 Software Utilities developer guide. These tools enable the following operations: * Formatting mDOC H3 * Creating multiple partitions for different storage needs (IPL, Boot loader, OS images files, and FAT partitions) * Programming the OS image file Figure 10 illustrates an example of a boot sequence. Power-Up Boot Loader Basic System Initialization Take Image from mDOC Boot Loader Copies OS Image to RAM mDOC H3 Flash Disk Partition (OS Image Storage) OS Start-Up Code Copy Image to RAM RAM Flash Disk Partition (File Storage) OS Image Figure 10: System Boot Sequence with mDOC H3 47 92-DS-1205-10 Booting from mDOC H3 mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 8.1.1 Asynchronous Boot Mode Host platforms should use Asynchronous Boot mode when using mDOC H3 as the system boot device. During platform initialization, certain CPUs wake up in 32-bit mode and issue instruction fetch cycles continuously. An Intel PXAxxx CPU, for example, initiates a 16-bit read cycle, but after the first word is read, it continues to hold CE# and OE# asserted while it increments the address and reads additional data as a burst. Once in Asynchronous Boot mode, the CPU can fetch its instruction from the mDOC H3 Programmable Boot Block. After reading from this block and completing the boot, mDOC H3 returns to derive its internal clock signal from the CE#, OE#, and WE# inputs. Please refer to Section 10 for read timing specifications for Asynchronous Boot mode. 8.1.2 Paged RAM Boot The Paged RAM Boot feature uses the IPL SRAM as two 1KB sections. The first section provides constant data, while the other section can be downloaded sequentially with flash data. One application of this feature is to support Secure Boot requirements. The Paged RAM Boot feature does not require support of the BUSY# output. After a hardware or software reset, mDOC H3 initializes the first 2KB of XIP RAM with data stored in the first 2KB of the pre-programmed IPL. The Paged RAM Boot feature permits 1KB virtual pages (up to 254KB total) to be downloaded sequentially to the XIP RAM, upon receiving the proper command sequence. Since the mDOC H3 BUSY# output is not asserted by a page-load operation, a polling procedure is required to determine when the download is complete. An XIP operation from the mDOC H3 RAM is not supported during this polling operation, so it must be executed from system RAM or ROM instead. When two mDOC H3 devices are cascaded, Paged RAM downloads occur only on the first mDOC H3 device in the cascaded configuration (device-0). For more information on booting from mDOC H3 in Paged RAM Boot mode, please contact your local SanDisk sales office. 48 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 9. DESIGN CONSIDERATIONS 9.1 General Guidelines * 9.2 A typical RISC processor memory architecture may include the following devices: * mDOC H3: Contains the OS image, applications, registry entries, back-up data, user files and data, etc. It can also be used to perform boot operation, thereby replacing the need for a separate boot device. * CPU: mDOC H3 is compatible with all major CPUs in the mobile phone, Digital TV (DTV), Digital Still Camera (DSC), MP3, GPS and other Portable Consumer Electronics Applications markets, including: * ARM-based CPUs * Texas Instruments OMAP, DBB * Intel PXAxxx family * Infineon xGold family * Analog Devices (ADI) digital Baseband devices * Freescale i.MXxx Application processors and i.xx digital Baseband devices * Zoran ER4525 * Renesas SH mobile * EMP platforms * Qualcomm MSMxxxx * Boot Device: In case mDOC H3 is not used as a boot device, ROM or NOR flash that contains the boot code is required for system initialization, kernel relocation, loading the operating systems and/or other applications and files into the RAM and executing them. * RAM/DRAM Memory: This memory is used for code execution. * Other Devices: A DSP processor, for example, may be used in a RISC architecture for enhanced multimedia support. Configuration The Configuration Interface enables the designer to configure mDOC H3 to operate in different modes. * The ID0 signal is used in a cascaded configuration. * The LOCK# signal is used for hardware write/read protection 9.3 Demux (Standard) Interface mDOC H3 uses a NOR-like interface that can easily be connected to any microprocessor bus. With a demux interface, it requires 16 address lines, 16 data lines and basic memory control signals (CE#, OE#, WE#), as shown in Figure 11 below. Typically, mDOC H3 can be mapped to any free 128KB memory space (8KB address space requires less address lines). 49 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 For power connectivity please refer to mDOC H3 power supply connectivity in section 9.5. Figure 11: Demux System Interface Notes: 1. mDOC H3 is an edge-sensitive device and care should be taken to prevent excessive ringing on the CE#, OE# and WE# signals. If required, these signals should be properly terminated (according to board layout; serial/parallel or both terminations) to avoid ringing 2. Address line A0 should either be connected to the host CPU A0 or to GND. 9.4 Multiplexed Interface With multiplexed interface, mDOC H3 requires the signals shown in Figure 12 below. For power connectivity please refer to mDOC H3 power supply connectivity in section 9.5. Figure 12: Multiplexed System Interface 50 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 Note: mDOC H3 is an edge-sensitive device and care should be taken to prevent excessive ringing on the CE#, OE# and WE# signals. If required, these signals should be properly terminated (according to board layout; serial/parallel or both terminations) to avoid ringing. 9.5 mDOC H3 Power Supply Connectivity mDOC H3 can be configured to support different combinations of Core (VCC) and IO (VCCQ) voltages. Table 4 lists the connectivity required to support the different available combinations. Table 4: Power Connectivity and Capacitors Power Supply Core: 3.3V IO: 3.3V Core: 3.3V IO: 1.8V VCC VCCQ 3.3V 3.3V Recommended: 0.1uF and 10nF 8 capacitors Recommended: 0.1uF and 10nF capacitors 3.3V 1.8V Recommended: 0.1uF and 10nF 8 capacitors Recommend: 0.1uF and 10nF capacitors VCC1 Required:1uF capacitor Recommended: Additional 0.1uF 9 capacitor Recommended: Additional 0.1uF 9 capacitor Core: 1.8V IO: 1.8V Required: 0.1 uF or 0.33 uF Recommended: 0.1uF and 10nF capacitors 14 Recommended: additional 10nF capacitor 8 No Capacitor10 3.3V 8 No Capacitor10 Required: 1uF or 1.5uF capacitor 1.8V 11 No Capacitor C+, C- 3.3V Required: 1uF capacitor 1.8V 1.8V VCC2 Recommended: Additional 0.1uF 12 capacitor Required: 33nF or 47nF capacitor13 Notes: 1. Voltages listed above are nominal voltages. 2. Capacitors that are listed as required must be installed. Failure to install these capacitors will cause the device to fail. 3. The values of capacitors listed as required are critical for proper operation of the device. The values listed are the minimum required values and may be increased. However any major deviations from the values specified above should be verified with SanDisk. 4. The values of capacitors listed as recommended may be modified based upon the specific behavior of the system power supply and board layout. These are bypass capacitors and they are required to minimize ripples on the power supply inputs. Failure to provide adequate bypass capacitors may cause intermittent problems. Designs that have been validated with different capacitor configurations do not need to follow these recommendations. 5. All capacitors are assumed to have a worst case tolerance of +/- 20%. 6. We recommend using an X7R type capacitor for all capacitors listed above. 51 92-DS-1205-10 Rev. 1.3 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet 7. The series inductance of the capacitors marked as required should be less than 15nH. 8. For this configuration, we recommend that the 0.1uF capacitor will be located close to the VCC ball and the 10nF capacitor will be located close to the VCC2 ball. If this placement is not possible then both capacitors should be located as close as possible to the VCC ball. The 10nF capacitor is only recommended in order to reduce high frequency noise. 9. For compatibility with next generation mDOC H3 devices we recommend adding an additional 0.1uF capacitor in parallel with the required 1uF capacitor. For designs that will only use the current mDOC H3 device only the 1uF capacitor is required. 10. In this configuration the internal charge pump is disabled. Installing a 33nF or 47nF capacitor will have no impact on the device. 11. In this configuration the voltage regulator is disabled and no capacitors are required on this ball. Installing a capacitor on this ball will have no impact on the device. 12. In this configuration the internal charge pump is enabled. The current mDOC H3 device requires at least a 1uF capacitor on VCC2 but it can also be operated with 1.5uF capacitor. However, for SDED5-AAAB-CCC devices, a 1.5uF will be required. The 0.1uF capacitor is only recommended in order to reduce high frequency noise. 13. This capacitor is critical for the operation of the internal charge pump. For the current mDOC H3 device a 33nF capacitor is required but it can also be operated with a 47nF capacitor. However, for for SDED5-AAAB-CCC devices, a 47nF capacitor will be required. 14. For the current mDOC H3 device a 0.1uF capacitor is required but it can also be operated with a 0.33uF capacitor. However, f for SDED5-AAAB-CCC devices, a 0.33uF capacitor will be required. This applies only to 1.8V Core and I/O configuration. 15. In case there are multiple balls available for a power supply then the recommended capacitors do not need to be duplicated for all balls but can be placed near one or more balls. 16. For systems that use a cascaded configuration, each mDOC H3 device must have its own set of required capacitors. Required capacitors cannot be shared between devices. Capacitors that are recommended can be shared between devices, however their effectiveness may be reduced. Careful analysis of the potential noise on the power supply pins should be conducted before deciding to share capacitors and reduce the total number of recommended capacitors. 17. The capacitors must be placed as close as possible to the package leads. Below are some drawings that depict the various power connectivity options. All options are valid for both MUX and DEMUX configurations. 18. BUSY#, DMARQ# and IRQ# should not be pulled up to any voltage higher than VCCQ. 52 92-DS-1205-10 Rev. 1.3 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Host Host control Figure 13: mDOC H3 power connection for 3.3v core/3.3v I/O Figure 14: mDOC H3 power connection for 3.3v core/1.8v I/O 53 92-DS-1205-10 Rev. 1.3 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Host Host control Figure 15: mDOC H3 power connection for 1.8v core/1.8v I/O 54 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 9.6 Connecting Control Signals 9.6.1 Demux Interface When using a demux NOR-like interface, connect the control signals as follows: * A[16:0] - Connect these signals to the host address signals (see Section 9.10 for platform-related considerations). The A0 signal may be connected to either the host CPU A0 signal or to VSS. * D[15:0] - Connect these signals to the host data signals (see Section 9.10 for platform-related considerations). * OE# (Output Enable) and Write Enable (WE#) - Connect these signals to the host RD# and WR# signals, respectively. * CE# (Chip Enable) - Connect this signal to the memory address decoder. Most RISC/mobile processors include a programmable decoder to generate various Chip Select (CS) outputs for different memory zones. These CS signals can be programmed to support different wait states to accommodate mDOC H3 timing specifications. * RSTIN# (Power-On Reset In) - Connect this signal to the host active-low Power-On Reset signal. * ID0 (Chip Identification) - This signal must be connected to VSS if the host uses only one mDOC H3. If more than one device is being used, refer to Section 9.9 for more information on device cascading. * BUSY# (Busy) - This signal indicates when the device is ready for first access after reset. It may be connected to an input port of the host, or alternatively it may be used to hold the host in a wait-state condition. The later option is required for hosts that boot from mDOC H3. * DMARQ# (DMA Request) - Output used to control multi-page DMA operations. Connect this output to the DMA controller of the host platform. * IRQ# (Interrupt Request) - Connect this signal to the host interrupt. * Lock# (LOCK) - Connect to a logical 0 to prevent the usage of the protection key to open a protected partition. Connect to logical 1 in order to enable usage of protection keys. * CLK (Clock) - This input is used to support Burst operation when reading flash data. Refer to Section 9.8 for further information on Burst operation. 9.6.2 Multiplexed Interface mDOC H3 can use a multiplexed interface to connect to a multiplexed bus. In this configuration, mDOC H3 AVD# signal is driven by the host's AVD# signal, and the D[15:0] balls, used for both address inputs and data, are connected to the host AD[15:0] bus. This mode is automatically entered when a falling edge is detected on AVD#. This edge must occur after RSTIN# is negated and before OE# and CE# are both asserted; i.e., the first read 55 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 cycle made to mDOC must observe the multiplexed mode protocol. See Section 10 for more information about the related timing requirements. Please refer to Section 2.3 for ballout and signal descriptions, and to Section 10 for timing specifications for a multiplexed interface. 9.7 Implementing the Interrupt Mechanism 9.7.1 Hardware Configuration To configure the hardware for working with the interrupt mechanism, the IRQ# ball should be connected to a host interrupt input. 9.7.2 Software Configuration IRQ# signal may be used by mDOC H3 to interrupt the host system, provided that device interrupts are enabled. Interrupts can be enabled or disabled using the flHwConfig DOC Driver API. For more information see the DOC Driver 1.0 Block Device (BD) Software Developer Kit (SDK) Developer Guide. When asserted, the IRQ# signal will remain asserted until cleaned (level only). This cleaning is performed automatically by the DOC Driver as part of the API (read or write) completion. mDOC H3 will interrupt the host system in the following cases: * Device is ready to receive a data block (excluding the first) during write operation. * When using DMA transfers: * On completion of block device operation to mDOC H3. * Device is ready to send a data block during a read operation. 9.8 DMA and Burst Operation mDOC H3 enhances performance using various proprietary techniques among them are * Burst operation to read or write large chunks of data, providing a Burst speed. * DMA operation to release the CPU for other tasks in coordination with the platform's DMA controller. This is especially useful during the boot stage. Up to 128KB of data can be transferred during a DMA operation. 9.8.1 DMA Operation mDOC H3 provides a DMARQ# output that enables data transfer using the host DMA controller. During DMA operation, the DMARQ# output is used to notify the host DMA controller that data is ready to be read or written. mDOC H3 protocol enables such data transfer up to the maximal size of 128KB per read or write operation. The DMARQ# output sensitivity is selected by setting the EDGE bit in the DMA Control register: 1. 56 Edge DMARQ# output pulses to indicate to the DMA controller that a data is ready to be transferred. The EDGE bit is set to 1 for this mode. The amount of data that will be transferred corresponds to data block size. 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 2. Level DMARQ# output is asserted while the data is available for read, or data can be accepted for write. The EDGE bit is set to 0 for this mode. The following steps are required in order to initiate a DMA operation: 1. If the DMA controller supports an edge-sensitive DMARQ# signal, then initialize the DMA controller to transfer 512 bytes (or your chosen data block size) upon each DMA request. If the DMA controller supports a level-sensitive DMARQ# signal, then initialize the DMA controller to transfer data continuously while DMARQ# is asserted. 2. Set in the DMA Control register values of EDGE bit, PULSE_WIDTH and DMA polarity corresponding to settings of the host DMA controller. This can be done only once after system power-up. 3. Enable DMA transfer with DMA_EN bit in the DMA control register. 4. If host DMA controller detects the de-assertion of the DMARQ# signal too late (and attempts to transfer additional words as a result), then DMARQ# can be configured to be deasserted earlier by using the DMA Negation Register. 5. Program host DMA controller to transfer the same number of sectors as will be given in following logical command. 6. Issue the DMA data-transfer read/write command with same number of sectors to transfer as given in the previous step (prior to this, the device should be instructed to perform transfers in DMA-mode). Upon command completion IRQ# will be asserted (it is recommended to use IRQ# when working with DMA). In case of a failure, less than expected amount of data could be transferred. In commands that use DMA transfer, IRQ# is activated only at the completion of the whole command; while in commands that do not use DMA transfer IRQ# is typically activated with every data transfer. Default setting of DMARQ# is level and active-low. It can be modified using the flHwConfig DOC Driver API. For more information see the DOC Driver 1.0 Block Device (BD) Software Developer Kit (SDK) Developer Guide.. 9.8.2 Synchronous Burst Operation In this mode the host reads full sections of 16-bit words synchronized to the CLK input. Burst operation is controlled by 5 bit fields in each Burst Mode Control register (one for Burst read and one for Burst write): BURST_EN, WAIT_STATE, LATENCY, HOLD and LENGTH. For full details on this register, please refer to Section 7. Burst Read / Write mode is enabled by setting the BURST_EN bit in each Burst Mode Control register. 57 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 9.8.2.1 Read Mode The LATENCY field controls the number of clock cycles between mDOC H3 sampling CE# being asserted and when the first word of data is available to be latched by the host. This number of clock cycles is equal to 3 + LATENCY. WAIT_STATE allows setting the number of CLK after the host has read the last word until the release of the CE#. * 1: One CLK clock before CE# release * 2: Two CLK clocks before CE# release * 3: Three CLK clocks before CE# release The HOLD bit in the Burst Mode Control register can be set to hold each data word valid for two clock cycles rather than one. Note: If HOLD = 1, then the data is available to be latched on this clock and on the subsequent clock. The LENGTH field must be programmed with the length of the burst to be performed (0 corresponds to 4 cycles; 1 to 8 cycles, 2 to 16 and 3 corresponds to 32 cycles). Each burst cycle must read exactly this number of words. The CLK input can be toggled continuously or can be halted. When halting the CLK input, the following guidelines must be observed: * The host must provide a clock signal for the full sequence defined by the LATENCY, WAIT STATE, HOLD and LENGTH bit fields. The clock can only be stopped after the release of CE#. * The clock can be halted momentarily during a burst sequence but the host must provide rising clock edges for the completion of the burst sequence. Note: For full information regarding the Synchronous Burst Mode see the DOC Driver 1.0 Block Device (BD) Software Developer Kit (SDK) Developer Guide.

Note: AVD must be asserted on the following clock after the assertion of CE. 2. No collision should be allowed between the AVD and OE signal. 9.8.2.2 Write Mode The Write mode is similar to the Read mode with the following exceptions: * WAIT_STATE = 0: 1 clock added. * WAIT_STATE = 1: 2 clocks added. * WAIT_STATE = 2: 3 clocks added. * WAIT_STATE = 3: 4 clocks added. Figure 1818: Demux Write Burst Mode Note: WE is sampled on the 1st clock after CE assertion. It must be active (low) for at least one clock cycle, after that the status of the WE signal is not important (O). 59 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 Figure 19: Multiplexed Write Burst Mode 9.9 Device Cascading Up to two devices can be cascaded with no external decoding circuitry. Figure 19 illustrates the configuration required to cascade two devices on the host bus (only the relevant cascading signals are included in this figure, although all other signals must also be connected). All balls of the cascaded devices must be wired in common, except for ID0. The ID ball values determine the identity of each device - the first device is identified by connecting the ID ball as 0, and the second device by connecting the ID ball as 1. Systems that use only one mDOC H3 should connect ID0 to GND. VSS VCCQ ID0 CE# OE# WE# CE# OE# WE# 1st ID0 2nd CE# OE# WE# Figure 19: mDOC H3 Cascaded Configuration 60 92-DS-1205-10 Rev. 1.3 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet 9.10 Platform-Specific Issues This section discusses hardware design issues for major embedded RISC processor families. 9.10.1 Wait State Wait states can be implemented only when mDOC H3 is designed in a bus that supports a Wait state insertion, and supplies a WAIT signal. 9.10.2 Big and Little Endian Systems mDOC H3 is a Little Endian device. Therefore, byte lane 0 (D[7:0]) is its Least Significant Byte (LSB) and byte lane 1 (D[15:8]) is its Most Significant Byte (MSB). Within the byte lanes, bit D0 and bit D8 are the least significant bits of their respective byte lanes. mDOC H3 can be connected to a Big Endian device in one of two ways: 1. Make sure to identify byte lane 0 and byte lane 1 of your processor. Then, connect the data bus so that the byte lanes of the CPU match the byte lanes of mDOC H3. Pay special attention to processors that also change the bit ordering within the bytes (for example, PowerPC). Failing to follow these rules results in improper connection of mDOC H3, and prevents the DOC Driver from identifying it. 2. If needed, set the SWAP bits in the Endian Control register. This enables byte swapping when used with big endian 16-bit hosts. 9.10.3 Busy Signal The Busy signal (BUSY#) indicates that mDOC H3 has not yet completed internal initialization. After reset, BUSY# is asserted while the IPL is downloaded into the internal boot block. Once the download process is completed, BUSY# is de-asserted. It can be used to delay the first access to mDOC H3 until it is ready to accept valid cycles. Note: mDOC H3 does NOT use this signal to indicate that the flash is in busy state (e.g. program, read, or erase). 9.10.4 Working with 16/32-Bit Systems mDOC H3 uses a 16-bit data bus and supports 16-bit data access by default. However, it can be configured to support 32-bit data access mode. This section describes the connections required for each mode. The default of the DOC Driver for mDOC H3 is set to work in 16-bit mode. It must be specially configured to support 32-bit mode. Please see DOC Driver or TrueFFS 7.1 documentation for further details. Note: The mDOC H3 data bus must be connected to the Least Significant Bits (LSB) of the system. 61 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 16-Bit (Word) Data Access Mode The mDOC H3 is 16 bit wide device. All accesses to and from the device are 16 bit wide. mDOC H3 address lines should be connected to system host address lines, as depicted in Figure 20. mDOC H3 A0 line should be connected either to system host SA0 address line, or to VSS. System Host SA16 A0 mDOC H3 Note: The prefix "SA" indicates system host address lines Figure 20: 16-Bit Data Access Mode 32-Bit (Double Word) Data Access Mode In a 32-bit bus system that cannot execute word-aligned accesses, the system address lines SA0 and SA1 are always 0. Consecutive double words (32-bit words) are differentiated by SA2 toggling. Therefore, in 32-bit systems that support only 32-bit data access cycles, mDOC H3 signal A1 is connected to the first system address bit that toggles; i.e., SA2. mDOC H3 address lines should be connected to system host address lines, as depicted in Figure 21. mDOC H3 A0 line should be connected either to system host SA1 address line, or to VSS System Host Note: The prefix "SA" indicates system host address lines Figure 21: Address Shift Configuration for 32-Bit Data Access Mode 62 92-DS-1205-10 Design Considerations mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 9.11 Design Environment mDOC H3 provides a complete design environment consisting of: * Evaluation boards (EVBs) for enabling software integration and development with mDOC H3, even before the target platform is available. * Programming solutions: * Programmer o Programming house o On-board programming o DOC Driver Software Development Kit (SDK) * TrueFFs 7.1 Software Development Kit (SDK) * XP utilities: o DFormat o DImage o DInfo * Documentation: o Data sheet o Application notes o Technical notes o Articles o White papers Please visit the SanDisk website (www.sandisk.com) for the most updated documentation. 63 92-DS-1205-10 Product Specifications mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 10.

When operating mDOC H3 with separate power supplies for VCCQ/VCC/VCC1/VCC2, it is recommended to turn the supplies on and off simultaneously. Providing power separately (either at power-on or power-off) can cause excessive power dissipation.

Providing power to one supply rail and not the other (either at power-on or power-off) can cause excessive power dissipation. Damage to the device may result if this condition persists for more than 500 msec. 10.3.12 Power-Up Timing mDOC H3 is reset by assertion of the RSTIN# input. When this signal is negated, mDOC H3 initiates a download procedure from the flash memory into the internal Programmable Boot Block. During this procedure, mDOC H3 does not respond to read or write access. Host systems must therefore observe the requirements described below for initial access to mDOC H3. Any of the following methods may be employed to guarantee first-access timing requirements: * Use a software loop to wait at least Tp (BUSY1) before accessing the device after the reset signal is negated. * Poll the state of the BUSY# output. * Use the BUSY# output to hold the host CPU in wait state before initiating the first access which will be a RAM read cycle. At least one of the signals CE# and OE# must be kept negated (high) until BUSY# is negated. Hosts that use mDOC H3 to boot the system must employ the latter option or use another method to guarantee the required timing of initial access. 77 92-DS-1205-10 Product Specifications mDOC H3 EFD Featuring Embedded TrueFFS Data Sheet Rev. 1.3 Table 23: Power-Up Timing Parameters Symbol TREC (VCC-RSTIN) Description VCC/VCCQ stable to RSTIN# C TW (RSTIN) RSTIN# asserted pulse width TP (BUSY0) RSTIN# E to BUSY# E TP (BUSY1) TP (VCC-BUSY0) Tsu (RSTIN-AVD) Tsu (BUSY-CE) Trise (RSTIN) RSTIN# C to BUSY# C Min 1 s 50 ns VCC/VCCQ stable to BUSY# E RSTIN# C to AVD# C BUSY# C to CE# E RSTIN# rise time Units 500 3 2 Max 50 ns 75 ms 500 s 3 s 0 s 20 ns Notes: 1.
