1 Introduction

1.1 General Description

SanDisk Compa ctF la sh® Memory Ca rd pr oduc ts pro v ide hig h capacity solid-state fla sh m emory

that electrically complies with the Persona l Computer Mem ory Card Internationa l Association

ATA (PC Card ATA) standard. (In Japan, the applica ble sta ndar ds gro up is JEIDA. ) The

CompactFlas h Memory Car d Series also sup por ts a True IDE Mode that is electr ica l ly

compatible with an IDE disk dr ive. The original CF form factor card can be used in an y system

that has a CF slot, and with a Type II PCMCIA adapter can be used in any system that h as a

PCMCIA Type II or Type III socket.

CompactFlash Memory cards use SanDisk F lash memory, which was designed by SanDisk

specifically for use in mass storage applications. In addition to the mass storage-specific flash

memory chips, Compac tF lash Mem ory cards include an on-ca rd intell ige nt contr ol ler that

provides a high level interface to the host computer. This interface allows a host computer to

issue commands to the me mory card to read or write blocks of m emory. The host addresses the

card in 512 byte sectors. Each sector is protected by a powerful Error Correcting Code (EC C).

The on-card intelligent controller in the Com pactFlash Memory Card manages interface

protocols, data storage and retr ieval as well as ECC, defect handlin g and diagnostics, power

managemen t and cloc k control. Once the card has been confi gured b y the host, it appear s to the

host as a standard ATA (IDE) disk drive. Addi tiona l ATA comm ands ha v e been provi ded to

enhance sys tem perform ance.

The host system can support as m any cards as there are CompactFlash and PCMCIA Type II or

III card slots. The original form factor CompactFlash Memory cards require a PCMCIA Type II

Adapter to be used in a PCMCIA Type II or Type III socket.

1.7 Functional Description

CompactFlash Memory cards contain a high level, intelli gent subsys tem as shown in the block

diagram, F igure 1-1. This intelligen t (microprocessor) subsystem provides many capabilities not

found in other types of memory cards. These capabilities include the follow ing:

• Standard ATA register and comm and set (same as found on most magnetic disk

drives).

• Host indepe ndence from details of erasin g and programming flash me mory.

• Sophisticated system for managing defects (analogous to systems found in ma gnetic

disk drives).

• Sophisticate d syste m for err or recovery inclu ding a pow erful err or correcti on code

(ECC).

• Power managem e nt for low power operatio n.

• Implementation of dynamic and static wear-leveling to extend card’s life.

1.7.1 Technology Independence

The 512-byte sector size of the CompactFlash Memory Card is the same as that in an IDE

magnetic dis k drive. To write or read a sector (or multiple sectors), the host computer software

simply issues a Read or Write command to the card. This command contains the address and the

number of sectors to write/read. The host software then waits for the command to complete.

The host softwar e does not get involve d in the details of how the flash memory is erased,

programmed or read. This is extreme ly important as flash dev ices are expecte d to get more a nd

more complex in the future. Because the CompactFlash Memory Card Series uses a n intelligent

on-board co ntroller, the host system software will not require changi ng as new flash memory

evolves. In other words, systems that support CompactFlash Memory cards now, will be able to

access future SanDisk cards built with new flash technology without having to update or change

host software.

1.7.2 Defect and Error Management

CompactFlash Memory cards contain a sophisticated defect and error management system . This

system is analogous to the systems found in magnetic disk drives and in many cases offers

enhancements. If necessary, the cards will rewrite data from a defective sector to a good sector.

This is completely trans par en t to the host and doe s not con sum e any user data space .

The CompactFlash Memory Card soft error rate specification is much better than the magnetic

disk drive specification. In the extremely rare case a read error does occur, CompactFlash

Memory cards ha ve innovative algorithms to recover the data by using hardware on-the-fly Error

Detection Code/Error Correction Code (EDC/ECC), based on a BCH algorithm.

These defec t and error m anagement systems, coupled with the solid state construction, give

SanDisk CompactFlash cards unparalleled reliability

1.7.3 Wear Leveling

Wear Leveling is an intrinsic pa rt of the erase pooling func t iona lit y of San Disk Compa c tF lash

using NAN D memory. The CF WEAR LEVEL comm and is sup por ted a s a NOP opera tion to

maintain backward compatib ility with exist ing software utilities. Advanced features of dynamic

and static wear-leveling, and automatic block management are used to ensure high data

reliability and maximize fla s h life expectancy.

1.7.4 Using Erase Sector and Write Commands

SanDisk Com pactFlash Memory cards support the CF ERASE SECTOR and WRITE

WITHOUT ERASE commands. In some applications, write operations may be faster if the

addresses bein g written are first erased with the ERASE SECTOR command. WRITE

WITHOUT ERASE behaves as a normal write command and no performance gain results from

its use.

1.7.5 Automatic Sleep Mode

A unique feature of the SanDisk CompactF lash Memory Card is automatic entrance and exit

from sleep mode. Upon completi on of a command, the card will en ter sleep mode to conserve

power if no further commands are received within 5 msec. The host does not have to take any

action for th is to occur. In most systems, the CompactFlash Memory Card is in sleep mode

except when the host is accessing it, thus conserving power. The dela y from command

completion t o entering sleep mode is adjustable.

When the host is ready to access the card and is in sleep mode, any comm and issue d to it will

cause the card to exit sleep and respond. The host does not have to follow the ATA protocol of

issuing a reset first. It may do this if desired, but it is not needed. By not issuing the reset,

performance is improved through the reduction of overhead but th is must be done only for the

SanDisk products as other ATA products m ay not sup port this fea tur e.

1.7.6 Dynamic Adjustment of Performance vs. Power Consumption

This feature is no longer supported. This command will be treated as a NOP (No Operation) to

guarantee backward compatibility.

1.7.7 Power Supply Requirements

This is a dual voltage product, which means it will operate at a voltage range of 3.30 volts ± 5%

or 5.00 volts ± 10%. Per the PCMCIA specification Se ct ion 2.1.1, the hos t system must apply 0

volts in order to change a voltage range. This same procedur e of providing 0 volts to the c ard is

required if the host system appl ies an inpu t volta ge outside t he des ired vol t age by more th an

15%. This means less than 4.25 vol ts for the 5.00-volt range and less t han 2.75 volts for the 3.30

volt range.

3.2 Electrical Description

The CompactFlash Memory Card Series is optimized for operation with hosts, which support the

PCMCIA I/O interface standa rd conforming to the PC Card ATA specification. However, the

card may also be configured to operate in systems that support onl y the memory interfac e

standard. The CompactFlash card configuratio n is controlled using the standard PCMCIA

configuratio n register s startin g at address 200h in the Attrib ute Memory sp ace of the card.

Table 3-4 describes the I/O signals. Signals whose so urce is the host are designated as inputs

while signa ls that the card sources are outputs. SanDisk CompactFlash Memory Card logic

levels conform to those specified in Section 3.3 of the PCMCIA Release 2.1 Specification.

NOTE: The sleep-to-write and sleep-to-re ad times are the time it takes the card to exit sleep

mode when any command is issued by the host to when the card is re ading or writing.

CompactFlash Memory cards do not require a reset to exit sleep mode.

The SanDisk CompactFlash Memory Card signals are described in Table 3-4.

Input Acknowledge

The Input Acknowledge signal is asserted

by the CompactFlash Storage Card or

CF+ Card when the card is selected and

responding to an I/O read cycle at the

address that is on the address bus. This

signal is used by the host to control the

enable of any input data buffers between

the CompactFlash Storage Card or CF+

Card and the CPU.

Hosts that support a single socket per

interface logic, such as for Advanced

Timing Modes and Ultra DMA operation

may ignore the –INPACK signal from the

device and manage their input buffers

based solely on Card Enable signals.

-DMARQ

(PC Card Memory Mode -

Ultra DMA Protocol

Active)

-DMARQ

(PC Card I/O Mode - Ultra

DMA Protocol Active)

DMARQ

(True IDE Mode)

This signal is a DMA Request that is used

for DMA data transfers between host and

device. It shall be asserted by the device

when it is ready to transfer data to or from

the host. For Multiword DMA transfers, the

direction of data transfer is controlled by

-IORD and -IOWR. This signal is used in a

handshake manner with (-) DMACK, i.e.,

the device shall wait until the host asserts

(-) DMACK before negating (-) DMARQ,

and re-asserting (-) DMARQ if there is

more data to transfer.

In PCMCIA I/O Mode, the -DMARQ shall

be ignored by the host while the host is

performing an I/O Read cycle to the

device. The host shall not initiate an I/O

Read cycle while -DMARQ is asserted by

the device.

In True IDE Mode, DMARQ shall not be

driven when the device is not selected in

the Drive-Head register.

While a DMA operation is in progress,

-CS0 (-CE1) and -CS1 (-CE2) shall be

held negated and the width of the

transfers shall be 16 bits.

If there is no hardware support for True

IDE DMA mode in the host, this output

signal is not used and should not be

connected at the host. In this case, the

BIOS must report that DMA mode is not

supported by the host so that device

drivers will not attempt DMA mode

operation.

A host that does not support DMA mode

and implements both PC Card and True

IDE modes of operation need not alter the

PC Card mode connections while in True

IDE mode as long as this does not prevent

proper operation in any mode.

O 37 In Memory Mode, this signal is set high

when the CompactFlash Storage Card or

CF+ Card is ready to accept a new data

transfer operation and is held low when

the card is busy.

At power up and at Reset, the READY

signal is held low (busy) until the

CompactFlash Storage Card or CF+ Card

has completed its power up or reset

function. No access of any type should be

made to the CompactFlash Storage Card

or CF+ Card during this time.

Note, however, that when a card is

powered up and used with RESET

continuously disconnected or asserted,

the Reset function of the RESET pin is

disabled. Consequently, the continuous

assertion of RESET from the application

of power shall not cause the READY

signal to remain continuously in the busy

state.
