Electrical description

The CompactFlash Memory Card operates in three basic modes:

● PC Card ATA using I/O Mode

● PC Card ATA using Memory Mode

● True IDE Mode, which is compatible with most disk drives

The signal/pin assignments are listed in Table 8 Low active signals have a ‘–’ prefix. Pin

types are Input, Output or Input/Output.

The configuration of the Card is controlled using the standard PCMCIA configuration

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

Table 9 describes the I/O signals. Inputs are signals sourced from the host while Outputs

are signals sourced from the Card. The signals are described for each of the three operating

modes.

All outputs from the Card are totem pole except the data bus signals that are bi-directional

tri-state. Refer to the section titled “Electrical Specifications” for definitions of Input and

Output type.
