THNCF008MBA Datasheet, PDF (30/48 Pages) Toshiba Semiconductor – The THNCFxxxMBA/BAI series CompactFlash card is a flash technology based with ATA interface flash memory card.

Preliminary
THNCFxxxMBA/BAI Series
(11) Read Long Sector (code 22h or 23h): This command performs similarly to the Read Sector(s) command
except that it returns 516 bytes of data instead of 512 bytes.
(12) Read Sector(s) (code 20h or 21h): This command reads from 1 to 256 sectors as specified in the Sector
Count register. A sector count of 0 requests 256 sectors. The transfer beings specified in the Sector
Number register.
(13) Read Verify Sector(s) (code: 40h or 41h): This command is identical to the Read Sectors command, except
that DRQ is never set and no data is transferred to the host.
(14) Recalibrate (code: 1Xh): This command is effectively a NOP command to the Card and is provided for
compatibility purposes.
(15) Request Sense (code: 03h): This command requests an extended error code after command ends with an
error.
(16) Seek (code: 7Xh): This command is effectively a NOP command to the Card although it does perform a
range check.
(17) Set Features (code: EFh): This command is used by the host to establish or select certain features.

Enable 8-bit data transfers.
Disable Read Look Ahead.
Disable Power on Reset (POR) establishment of defaults at Soft Reset.
Disable 8-bit data transfers.
4 bytes of data apply on Read/Write Long commands.
Enable Power on Reset (POR) establishment of defaults at Soft Reset.
(18) Set Multiple Mode (code: C6h): This command enables the Card to perform Read and Write Multiple
operations and establishes the block count for these commands.
(19) Set Sleep Mode (code: E6h or 99h): This command causes the Card to set BSY, enter the Sleep mode,
clear BSY and generate an interrupt.
(20) Stand By (code: E2h or 96h): This command causes the Card to set BSY, enter the Sleep mode (which
corresponds to the ATA “Standby” Mode), clear BSY and return the interrupt immediately.
(21) Stand By Immediate (code: E0h or 94h): This command causes the Card to set BSY, enter the Sleep mode
(which corresponds to the ATA “Standby” Mode), clear BSY and return the interrupt immediately.
(22) Translate Sector (code: 87h): This command allows the host a method of determining the exact number of
times a use sector has been erased and programmed.
(23) Wear Level (code: F5h): This command effectively a NOP command and only implemented for backward
compatibility. The Sector Count Register will always be returned with a 00h indicating Wear Level is
not needed.
(24) Write Buffer (code: E8h): This command enables the host to overwrite contents of the Card’s sector buffer
with any data pattern desired.
(25) Write Long Sector (code: 32h or 33h): This command is provided for compatibility purposes and is
similar to the Write Sector(s) command except that it writes 516 bytes instead of 512 bytes.
(26) Write Multiple (code: C5h): This command is similar to the Write Sectors command. Interrupts are not
presented on each sector, but on the transfer of a block which contains the number of sectors defined by
Set Multiple command.
(27) Write Multiple without Erase (code: CDh): This command is similar to the Write Multiple command with
the exception that an implied erase before write operation is not performed.
(28) Write Sector(s): (code: 30h or 31h): This command writes from 1 to 256 sectors as specified in the Sector
Count register. A sector count of zero requests 256 sectors. The transfer begins at the sector specified
in the Sector Number register.
(29) Write Sector(s) without Erase (code: 38h): This command is similar to the Write Sector(s) command with
the exception that an implied erase before write operation is not performed.
(30) Write Verify (code: 3Ch): This command is similar to the Write Sector(s) command, except each sector is
verified immediately after being written.
