2.3 EB8541 E²Brain™ Module Interfaces

The following sections provide a very brief description of the interfacing between the E²Brain™

module and the EBC-VME3 board.

2.3.1 System Interface

As the name implies, this interface provides the basic application connection functionality re-

quired to integrate the EB8541 E²Brain™ module as the high performance core of the VMP3.

The System Interface is realized using a 140-pin, HIROSE FX8C-140P-SV connector. The fol-

lowing table provides an overview of the signal types and a brief description of the interfacing

realized on this connector.

2.3.2 System Interface Extension

The System Interface Extension is realized using an 80-pin, HIROSE FX8C-80P-SV connector,

and it is used to provide CPU architecture specific system interfaces.

In the case of the VMP3, a CompactFlash interface is made available on the System Interface

Extension.

2.3.3 Communications Interface

The Communications Interface Connector is used to provide a set of standard communications

interfaces. In the case of the VMP3, there are three types of interfaces provided: four high

speed serial interfaces, one CAN interface, and one Fast Ethernet interface.

SIGNAL TYPE DESCRIPTION

POWER VMP3 E²Brain™ module input power, grounds, battery backup power, PCI

signaling voltage V(I/O)

MONITOR AND CONTROL (M/C) Control signals for E²Brain™ module operation, configuration, and addi-

tional GPIO interfacing

TEST AND PROGRAMMING (T/P) JTAG/Debug signals for Emulator interfacing

TERMINAL AND

CONSOLE (T/C)

Two 2-wire serial interfaces:

RxD1/TxD1: Used by the boot loader during startup as a terminal interface;

once the system has been booted, is available as general pur-

pose serial interface (Terminal)

RxD2/TxD2: general purpose serial interface (Console)

I2C One I2C standard interface for low speed, serial, inter-chip communica-

tions

LPC One LPC standard interface for (GP)IOs and simple memory interfacing

PCI One PCI standard interface for PCI-bus interfacing
