The signals are arranged in functional groups according to their associated interface. The pin descriptions are applied when using the internal default firmware and can be referenced in Chapter 8, "Configuration Options," on page 24. Please reference Chapter 1, "Acronyms," on page 6 for a list of the acronyms used. The "n" symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When "n" is not present in the signal name, the signal is asserted at the high voltage level. The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of "active low" and "active high" signals. The term assert, or assertion, indicates that a signal is active, independent of whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inactive. 6.1 128-Pin VTQFP Pin Descriptions Table 6.1 USB2250/50i/51/51i 128-Pin VTQFP Pin Descriptions NAME SYMBOL 128-PIN VTQFP BUFFER TYPE DESCRIPTION COMPACT FLASH (CF) INTERFACE CF Chip Select 0 CF_nCS0 71 O12PU This pin is the active low chip select 0 signal for the task file registers of the CF ATA device in True IDE mode.

The VBUS_DET pin on the device monitors the state of the upstream VBUS signal and will not pull-up the D+ resistor if VBUS is not active. If VBUS goes from an active to an inactive state (not powered), the device will remove power from the D+ pull-up resistor within 10 seconds. 8.2 System Configurations 8.2.1 EEPROM The USB2250/50i/51/51i can be configured via a 2-wire (I2C) EEPROM (512x8) flash device containing the options for the USB2250/50i/51/51i. If an external configuration device does not exist the internal default values will be used. If one of the external devices is used for configuration, the OEM can update the values through the USB interface. The device will then "attach" to the upstream USB host. The USBDM tool set is available in the USB224x/USB225x Card Reader software release package.

The hub is either self-powered (draws less than 2 mA) or bus-powered (limited to 100 mA maximum power prior to being configured by the host controller). When configured as a bus-powered device, the SMSC device consumes less than 100 mA of current prior to being configured. After configuration, the bus-powered SMSC device (along with all associated device circuitry, any embedded devices if part of a compound device, and 100 mA per externally available downstream port) must consume no more than 500 mA of current. The current consumption is system dependent, and the OEM must ensure that the USB 2.0 Specification is not violated. When configured as a self-powered device, <1 mA of current is consumed and all ports are available, with each port being capable of sourcing 500 mA of current. 80 = Bus-powered operation (default) C0 = Self-powered operation A0 = Bus-powered operation with remote wake-up E0 = Self-powered operation with remote wake-up 8.2.3.18 9Bh: USB MaxPower (1 byte) BIT NAME 7:0 USB_MAX_PWR SMSC USB2250/50i/51/51i DESCRIPTION USB Max Power per the USB 2.0 Specification.

The high bit (7) indicates an idle state: `0' - Off `1' - On The remaining bits (6:0) are used to determine the blink interval up to a max of 63 x 50 ms. 8.2.4.6 A9h: LED Blink Duration BYTE NAME 1 LED_BLK_DUR 8.2.5 DESCRIPTION LED Blink After Access. This byte is used to designate the number of seconds that the GPIO1 LED will continue to blink after a drive access. Setting this byte to "05" will cause the GPIO 1 LED to blink for 5 seconds after a drive access. Device ID Strings These bytes are used to specify the LUN descriptor returned by the device. These bytes are used in combination with the device to LUN mapping bytes in applications where the OEM wishes to reorder and rename the LUNs. If multiple devices are mapped to the same LUN (a COMBO LUN), then the CLUN#_ID_STR will be used to name the COMBO LUN instead of the individual device strings. When applicable, the "SM" value will be overridden with xD once an xD-Picture Card has been identified.

D3h: Dynamic Number of LUNs BIT NAME DESCRIPTION 7:0 DYN_NUM_LUN These bytes are used to specify the number of LUNs the device exposes to the host. These bytes are also used for icon sharing by assigning more than one LUN to a single icon. This is used in applications where the device utilizes a combo socket and the OEM wishes to have only a single icon displayed for one or more interfaces. If this field is set to "FF", the program assumes that you are using the default value and icons will be configured per the default configuration. SMSC USB2250/50i/51/51i 33 DATASHEET Revision 2.0 (09-29-09) Ultra Fast USB 2.0 Multi-Slot Flash Media Controller Datasheet 8.2.5.8 D4h-D7h: Device to LUN Mapping BYTE NAME DESCRIPTION 3:0 DEV_LUN_MAP These registers map a device controller (SD/MMC, SM, and MS) to a Logical Unit Number (LUN). The device reports the mapped LUNs to the USB host in the USB descriptor during enumeration. The icon installer associates custom icons with the LUNs specified in these fields. Setting a register to "FF" indicates that the device is not mapped. Setting all of the DEV_LUN_MAP registers for all devices to "FF" forces the use of the default mapping configuration. Not all configurations are valid. Valid configurations depend on the hardware, packaging, and OEM board layout. The number of unique LUNs mapped must match the value in the Section 8.2.5.7, "D3h: Dynamic Number of LUNs," on page 33. 8.2.5.9 D8h-FBh: Not Applicable BYTE NAME 35:0 Not Applicable 8.2.5.10 DESCRIPTION Not Applicable. FCh-FFh: Non-Volatile Storage Signature BYTE NAME DESCRIPTION 3:0 NVSTORE_SIG This signature is used to verify the validity of the data in the first 256 bytes of the configuration area. The signature must be set to `ATA2' for USB2250/50i/51/51i. 8.3 Default Configuration Option The SMSC device can be configured via its internal default configuration. Please see Section 8.2.2, "EEPROM Data Descriptor" for specific details on how to enable default configuration. Please refer to Table 8.1 for the internal default values that are loaded when this option is selected. 8.3.1 External Hardware nRESET A valid hardware reset is defined as assertion of nRESET for a minimum of 1 s after all power supplies are within operating range. While reset is asserted, the device (and its associated external circuitry) consumes less than 500 A of current. Assertion of nRESET (external pin) causes the following: 1. The PHY is disabled and the differential pair will be in a high-impedance state. 2. All transactions immediately terminate; no states are saved. 3.

However, the OEM PCB itself may present a parasitic capacitance between XTAL1 and XTAL2. For an accurate calculation of C1 and C2, take the parasitic capacitance between traces XTAL1 and XTAL2 into account. Note 9.2 Each of these capacitance values is typically approximately 18 pF.

When internal power FET operation of these pins are enabled, these pins may be simultaneously shorted to ground or any voltage up to 3.63 V indefinitely, without damage to the device as long as VDD33 is less than 3.63 V and TA is less than 70oC. Note 10.1 Stresses above the specified parameters may cause permanent damage to the device. This is a stress rating only and functional operation of the device at any condition above those indicated in the operation sections of this specification is not implied. Note 10.2 When powering this device from laboratory or system power supplies, it is important that the absolute maximum ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output. When this possibility exists, it is suggested that a clamp circuit be used.
