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
