2.0 ELECTRICAL INTERFACE
2.0.1 Pin Assignment and Pin Type
The signal/pin assignments are listed in
Table 2-1. Low active signals have a “-” prefix. Pin types are Input, Output or Input/
Output. Section
2.3 defines the DC characteristics for all input and output type structures.
2.1 Electrical Description
The CompactFlash card functions in three basic modes: 1) PC Card ATA using I/O mode, 2) PC Card ATA using Memory
mode and 3) True IDE mode, which is compatible with most disk drives. The configuration of the CompactFlash card will be
controlled using the standard PCMCIA configuration registers starting at address 200H in the Attribute Memory space of the
storage card or for True IDE mode, pin 9 being grounded.
Table 2-2 describes the I/O signals. Signals whose source is the host are designated as inputs while signals that the Com-
pactFlash card sources are outputs. The CompactFlash card logic levels conform to those specified in the PCMCIA Release
2.1 and CFA Specification Rev. 1.4. As shown in
Table 2-2, each signal has three possible operating modes: 1) PC Card
Memory, 2) PC Card I/O and 3) True IDE. All outputs from the card are totem pole except the data bus signals which are bi-
directional tri-state. Refer to Section
2.3 for definitions of Input and Output type.
