133X CompactFlash Card

Transcend Information Inc.

Words 7-8: Number of Sectors per Card

This field contains the number of sectors per CompactFlash Storage Card. This double word

value is also the first invalid address in LBA translation mode.

Words 10-19: Serial Number

This field contains the serial number for this CompactFlash Storage Card and is right justified and padded

with spaces (20h).

Word 22: ECC Count

This field defines the number of ECC bytes used on each sector in the Read and Write Long commands.

This value shall be set to 0004h.

Words 23-26: Firmware Revision

This field contains the revision of the firmware for this product.

Words 27-46: Model Number

This field contains the model number for this product and is left justified and padded with spaces (20h).

Word 47: Read/Write Multiple Sector Count

Bits 15-8 shall be the recommended value of 80h or the permitted value of 00h. Bits 7-0 of this word define

the maximum number of sectors per block that the CompactFlash Storage Card supports for Read/Write

Multiple commands.

Word 49: Capabilities

Bit 13: Standby Timer

If bit 13 is set to 1 then the Standby timer is supported as defined by the IDLE command

If bit 13 is set to 0 then the Standby timer operation is defined by the vendor.

Bit 11: IORDY Supported

If bit 11 is set to 1 then this CompactFlash Storage Card supports IORDY operation.

If bit 11 is set to 0 then this CompactFlash Storage Card may support IORDY operation.

Bit 10: IORDY may be disabled

Bit 10 shall be set to 0, indicating that IORDY may not be disabled.

Bit 9: LBA supported

Bit 9 shall be set to 1, indicating that this CompactFlash Storage Card supports LBA mode addressing. CF

devices shall support LBA addressing.

Bit 8: DMA Supported If bit 8 is set to 1 then Read DMA and Write DMA commands are supported. Bit 8

shall be set to 0. Read/Write DMA commands are not currently permitted on CF cards.

PIO Data Transfer Cycle Timing Mode

The PIO transfer timing for each CompactFlash Storage Card falls into modes that have unique parametric

timing specifications. The value returned in Bits 15-8 shall be 00h for mode 0, 01h for mode 1, or 02h for

mode 2. Values 03h through FFh are reserved.

Translation Parameters Valid

Bit 0 shall be set to 1 indicating that words 54 to 58 are valid and reflect the current number of cylinders,

heads and sectors. If bit 1 of word 53 is set to 1, the values in words 64 through 70 are valid. If this bit is

cleared to 0, the values reported in words 64-70 are not valid. Any CompactFlash Storage Card that

supports PIO mode 3 or above shall set bit 1 of word 53 to one and support the fields contained in words

64 through 70.

Current Number of Cylinders, Heads, Sectors/Track

These fields contains the current number of user addressable Cylinders, Heads, and Sectors/Track in the

current translation mode.

Current Capacity

This field contains the product of the current cylinders times heads times sectors.
