4 Connector Pin Assignments

Introduction

This chapter provides connector pin assignments for all connectors on the PrPMC800/800ET

board.

PCI Mezzanine Card (PMC) Connectors

There are four 64-pin EIA E700 AAAB SMT connectors (P11, P12, P13, and P14) on the

PrPMC800/800ET that provide the 32/64-bit PCI interface and optional I/O interface to the host

board. The P14 connector provides an interface to the bank B flash and I

C bus along with a

secondary interface to the serial port and the JTAG/COP port. The pin assignments are as

follows.
