HARDWARE DESCRIPTION
Introduction
This chapter describes the board level hardware features of the MVME162
Embedded Controller. 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.

Overview
The MVME162 is based on the MC68040 or MC68LC040 microprocessor.
Various versions of the MVME162 have 1 MB, 4 MB, or 8 MB of parity-
protected DRAM, 8 KB of SRAM (with battery backup), time of day clock (with
battery backup), Ethernet transceiver interface, two serial ports with EIA-232-
D or EIA-530 interface, six tick timers, watchdog timer, a PROM socket, 1 MB
Flash memory (one or four Flash devices), four IndustryPack (IP) interfaces,
SCSI bus interface with DMA, VMEbus controller, and 512 KB of SRAM with
battery backup.

The I/O on the MVME162 is connected to the VMEbus P2 connector. The main
board is connected through a P2 transition board and cables to the transition
boards. The MVME162 supports the transition boards MVME712-12,
MVME712-13, MVME712M, MVME712A, MVME712AM, and MVME712B
(referred to in this manual as MVME712X, unless separately specified). The
MVME712X transition boards provide configuration headers and provide
industry standard connectors for the I/O devices.

The I/O connection for the serial ports on the MVME162 is also provided by
two DB-25 front panel I/O connectors. The MVME712 series transition boards
were designed to support the MVME167 boards, but can be used on the
MVME162 by following some special precautions. (Refer to the section on the
Serial Communications Interface, later in this chapter, for more information.)
