Introduction

This chapter describes the board level hardware features of the MVME197LE Single Board Computer. The chapter is organized with a board level overview and features listed in this introduction, followed by a more detailed hardware functional description. Front panel switches and indicators are included in the detailed hardware functional description. This chapter closes with some general memory maps.

All programmable registers in the MVME197LE module reside in ASICs (Application-Specific Integrated Circuits) that are covered in the MVME197LE, MVME197DP, and MVME197SP Single Board Computers Programmer’s Reference Guide.

Overview

The MVME197LE module is a double-high VMEmodule based on the MC88110 RISC microprocessor. The MVME197LE has 32/64MB of DRAM, 1MB of flash memory, 8KB of static RAM (with battery backup), a time of day clock (with battery backup), an Ethernet transceiver interface, four serial ports with EIA-232-D interface, six tick timers, a watchdog timer, 128KB of BOOT ROM, a SCSI bus interface with DMA (Direct Memory Access), a Centronics printer port, an A16/A24/A32/D8/D16/D32 VMEbus master/slave interface, and a VMEbus system controller.

Input/Output (I/O) signals are routed through the MVME197LE’s backplane connector P2. A P2 Adapter Board or LCP2 Adapter board routes the signals and grounds from connector P2 to an MVME712 series transition module. The MVME197LE supports the MVME712M, MVME712A, MVME712AM, and MVME712B transition boards (referred to here as the MVME712X, unless separately specified). The MVME197LE also supports the MVME712-12 and MVME712-13 (referred to as the MVME712-XX, unless separately specified). These transition boards provide configuration headers, serial port drivers, and industry standard connectors for the I/O devices.

The MVME197LE modules have eight ASICs (described in the following order: BusSwitch, DCAM, ECDM, PCC2, and VME2).
