3.5.1
PC Card Insertion/Removal and Recognition
The
PC Card Standard
(release 7.1) addresses the card-detection and recognition process through an interrogation
procedure that the socket must initiate on card insertion into a cold, nonpowered socket. Through this interrogation,
card voltage requirements and interface (16-bit versus CardBus) are determined.
The scheme uses the card-detect and voltage-sense signals. The configuration of these four terminals identifies the
card type and voltage requirements of the PC Card interface. The encoding scheme is defined in the
PC Card
Standard
(release 7.1) and in Table 3
–
1.

C Power-Switch Interface (TPS222X)
The PCI1520 provides a PCMCIA peripheral control (P
2
C) interface for control of the PC Card power switch. The
CLOCK, DATA, and LATCH terminals interface with the TI TPS222X dual-slot PC Card power interface switches to
provide power switch support. Figure 3
–
3 illustrates a typical application where the PCI1520 represents the PCMCIA
controller. Table 3
–
2 shows the available power switch options compatible with the PCI1520.
