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.
All programmable registers in the MVME162 that reside in ASICs are covered in the MVME162 Embedded Controller Programmer’s Reference Guide.
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
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
The I/O connection for the serial ports on the MVME162 is also provided by two
