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 card may also be configured to operate in systems that support only the memory interface

standard. The CompactFlash card configuration is controlled using the standard PCMCIA

configuration registers starting at address 200h in the Attribute Memory space of the card.

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

while signals 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-read 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 reading or writing. CompactFlash Memory cards do

not require a reset to exit sleep mode.
