Introduction

This chapter describes the board level hardware features of the MVME166 Single Board Computers. The chapter is organized with a board level overview and features list in this introduction, followed by a more detailed hardware functional description. Front panel switches and indicators are included in the detailed hardware functional description. The chapter closes with some general memory maps.

All programmable registers in the MVME166 that reside in ASICs are covered in the MVME166/MVME167/MVME187 Single Board Computers Programmer’s Reference Guide.

Overview

The MVME166 is based on the MC68040 microprocessor. The MVME166 has 4/8/16/32/64/128/256 MB of ECC-protected DRAM, 1 MB of Flash memory with download EPROM, 128KB of static RAM (with battery backup), 8KB of static RAM and time of day clock (with battery backup), Ethernet transceiver interface, four serial ports with TTL interface, four tick timers, watchdog timer, SCSI bus interface with DMA, Centronics printer port, A16/A24/A32/D8/D16/D32/D64 VMEbus master/slave interface, VMEbus system controller, and a VSB interface.

The I/O connection for the MVME166 is provided by two high density shielded front panel I/O connectors. The SCSI bus is connected through a 68 pin connector. The printer, four serial ports and Ethernet interface are connected through a 100 pin connector. The MVME712-10 transition module and the MVME712-06/07/09 I/O distribution board set were designed to support the MVME166 boards. These transition boards provide configuration headers, serial port drivers and industry standard connectors for the I/O devices.

The VMEbus interface is provided by an ASIC called the VMEchip2. The VMEchip2 includes two tick timers, a watchdog timer, programmable map decoders for the master and slave interfaces, and a VMEbus to/from local bus DMA controller, a VMEbus to/from local bus non-DMA programmed access interface, a VMEbus interrupter, a VMEbus system controller, a VMEbus interrupt handler, and a VMEbus requester.
