Introduction
This chapter provides a block diagram level description of the MVME197LE Single Board Computer. The functional description provides an overview of the module, followed by a detailed description of several blocks of the module. The block diagram for the MVME197LE is illustrated in Figure
Descriptions of the other blocks of the MVME197LE module, including programmable registers in the ASICs and peripheral chips, are given in the MVME197LE, MVME197DP, and MVME197SP Single Board Computers Programmer’s Reference Guide. Refer to it for the rest of the functional description of the MVME197LE module.
MVME197LE Functional Description
The MVME197LE module is a high functionality VMEbus single board computer based on the MC88110 second generation RISC microprocessor. The MVME197LE has 32/64MB of DRAM, 1MB of FLASH memory, 128/256KB of BOOT ROM, 8KB of static RAM (with battery backup), a time of day clock (with battery backup), an Ethernet transceiver interface, four serial ports with
Data Bus Structure
The local data bus on the MVME197LE module is designed to accommodate the various
MC88110 MPU
The MVME197LE is based on the MC88000 family and uses one MC88110 RISC microprocessor unit. Refer to the MC88110 Second Generation RISC Microprocessor User’s Manual for more information.
