Retail CompactFlash specifications are not covered in this manual. 1.2. System Features CompactFlash provides the following system features: • • • • • • • • • • • • • • • Up to 1.
Introduction to the CompactFlash Memory Card 1.4. CompactFlash Specification CompactFlash Memory Cards are fully compatible with the CompactFlash Specification published by the CompactFlash Association. Contact the CompactFlash Association for more information. CompactFlash Association P.O. Box 51537 Palo Alto, CA 94303 USA Phone: 415-843-1220 FAX: 415-493-1871 www.compactflash.org 1.5. Related Documentation ATA operation is governed by the ATA-2 specification published by ANSI.
Introduction to the CompactFlash Memory Card 1.6.1. Technology Independence The 512-byte sector size of the CompactFlash Memory Card is the same as that in an IDE magnetic disk drive. To write or read a sector (or multiple sectors), the host computer software simply issues a Read or Write command to the CompactFlash Memory Card. This command contains the address and the number of sectors to write/read. The host software then waits for the command to complete.
Introduction to the CompactFlash Memory Card 1.6.5. Automatic Sleep Mode A unique feature of the SanDisk CompactFlash Memory Card (and other SanDisk products) is automatic entrance and exit from sleep mode. Upon completion of a command, the CompactFlash Card will enter sleep mode to conserve power if no further commands are received within 5 msec. The host does not have to take any action for this to occur.

CompactFlash Memory Card Interface Description 3.2. Electrical Description The CompactFlash Memory Card Series is optimized for operation with hosts, which support the PCMCIA I/O interface standard conforming to the PC Card ATA specification. However, the CompactFlash Card may also be configured to operate in systems that support only the memory interface standard.
CompactFlash Memory Card Interface Description Signal Name Dir. Pin Description -CE1, -CE2 (PC Card Memory Mode) Card Enable I 7, 32 These input signals are used both to select the card and to indicate to the card whether a byte or a word operation is being performed. -CE2 always accesses the odd byte of the word. -CE1 accesses the even byte or the Odd byte of the word depending on A0 and -CE2. A multiplexing scheme based on A0, -CE1, -CE2 allows 8 bit hosts to access all data on D0 -D7.
CompactFlash Memory Card Interface Description Signal Name Dir. Pin -IOWR (PC Card Memory Mode) I 35 -IOWR (PC Card I/O Mode) Description This signal is not used in this mode. The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into the CompactFlash controller registers when the card is configured to use the I/O interface. The clocking will occur on the negative to positive edge of the signal (trailing edge).
CompactFlash Memory Card Interface Description Signal Name Dir. Pin Description -VS1 -VS2 (PC Card Memory Mode) O 33 40 Voltage Sense Signals. -VS1 is grounded so that the CompactFlash Card CIS can be read at 3.3 volts and -VS2 is open and reserved by PCMCIA for a secondary voltage. -VS1 -VS2 (PC Card I/O Mode) This signal is the same for all modes. -VS1 -VS2 (True IDE Mode) This signal is the same for all modes.

CompactFlash Memory Card Interface Description RRdy/-Bsy This bit is used to determine the internal state of the Rdy/-Bsy signal. This bit may be used to determine the state of the Ready/-Busy as this pin has been reallocated for use as Interrupt Request on an I/O card. When written, this bit acts as a mask for writing the corresponding bit CRdy/-Bsy. RWProt This bit is always zero (0) since the CompactFlash Memory Card does not have a Write Protect switch.
CompactFlash Memory Card Interface Description 3.5.1. I/O Function The I/O transfer to or from the CompactFlash Memory Card can be either 8 or 16 bits. When a 16-bit accessible port is addressed, the signal -IOIS16 is asserted by the CompactFlash Card. Otherwise, the -IOIS16 signal is de-asserted. When a 16-bit transfer is attempted, and the -IOIS16 signal is not asserted by the CompactFlash Card, the system must generate a pair of 8-bit references to access the word‘s even byte and odd byte.
CompactFlash Memory Card Interface Description Table 3-23.
4. ATA Drive Register Set Definition and Protocol The CompactFlash Memory Card can be configured as a high performance I/O device through the following ways: • • • Standard PC-AT disk I/O address spaces 1F0h-1F7h, 3F6h-3F7h (primary); 170h-177h, 376h-377h (secondary) with IRQ 14 (or other available IRQ). Any system decoded 16-byte I/O block using any available IRQ. Memory space.
ATA Drive Register Set Definition and Protocol 1. Register 0 is accessed with -CE1 low and -CE2 low (and A0 = Do not care) as a word register on the combined Odd Data Bus and Even Data Bus (D15-D0). This register may also be accessed by a pair of byte accesses to the offset 0 with -CE1 low and -CE2 high. Note that the address space of this word register overlaps the address space of the Error and Feature byte-wide registers that lie at offset 1.
ATA Drive Register Set Definition and Protocol 4.3. Memory Mapped Addressing When the CompactFlash Memory Card registers are accessed via memory references, the registers appear in the common memory space window: 0-2K bytes as shown in Table 4-4. Table 4-4.
ATA Drive Register Set Definition and Protocol 4.4. True IDE Mode Addressing When the CompactFlash Memory Card is configured in the True IDE Mode the I/O decoding is as listed in Table 4-5.

Sector Number (LBA 7-0) Register (Address—1F3[173]; Offset 3) This register contains the starting sector number or bits 7-0 of the Logical Block Address (LBA) for any CompactFlash Memory Card data access for the subsequent command. 4.5.6. Cylinder Low (LBA 15-8) Register (Address—1F4[174]; Offset 4) This register contains the low order 8 bits of the starting cylinder address or bits 15-8 of the Logical Block Address. 4.5.7.
ATA Drive Register Set Definition and Protocol 4.5.9. Status & Alternate Status Registers (Address 1F7[177]&3F6[376]; Offsets 7 & Eh) These registers return the CompactFlash Memory Card status when read by the host. Reading the Status register does clear a pending interrupt while reading the Auxiliary Status register does not.
ATA Drive Register Set Definition and Protocol 4.5.11. Card (Drive) Address Register (Address 3F7[377]; Offset Fh) This register is provided for compatibility with the AT disk drive interface. It is recommended that this register not be mapped into the host's I/O space because of potential conflicts on Bit 7. The bits are defined as follows: D7 D6 D5 D4 D3 D2 D1 D0 X -WTG -HS3 -HS2 -HS1 -HS0 -nDS1 -nDS0 Bit 7 This bit is unknown.
5. ATA Command Description This section defines the software requirements and the format of the commands the host sends to the CompactFlash Memory Cards.
