1.1.1 General Description
The Philips PR31500/PR31700 processor supports up to two PC Card (PCMCIA) slots. It is through
this host bus interface that the S1D13504 connects to the PR31500/PR31700 processor.
The S1D13504 can be successfully interfaced using one of three configurations:
• Direct connection to PR31500/PR31700 (see Section 1.2, “Direct Connection to the Philips
PR31500/PR31700” on page 2).
• System design using one ITE8368E PC Card/GPIO buffer chip (see Section 1.3.1, “Hardware
Description—Using One IT8368E” on page 4).
• System design using two ITE8368E PC Card/GPIO buffer chips (see Section 1.3.2, “Hardware
Description—Using Two IT8368E’s” on page 5).
