MVME162 Embedded Controller MOTOROLA

The MVME162 User’s Manual provides general information, hardware preparation and installation instructions, operating instructions, and a functional description for the MVME162 Embedded Controller.
This manual is intended for anyone who wants to design OEM systems, supply additional capability to an existing compatible system, or work in a lab environment for experimental purposes.
A basic knowledge of computers and digital logic is assumed. To use this manual, you should be familiar with the publications listed in the Related Documentation section in Chapter 1 of this manual.

Features of the MVME162 include:
❏ 25MHz 32-bit Microprocessor: either an MC68LC040 Enhanced 32-bit Microprocessor with 8KB of cache and MMU, or an optional 25MHz MC68040 32-bit Microprocessor with 8KB of cache, MMU, and FPU
❏ 1MB, 4MB, or 8MB of shared Dynamic Random Access Memory (DRAM) with programmable parity
❏ 512KB of Static Random Access Memory (SRAM) with battery backup
❏ One JEDEC standard 32-pin PLCC EPROM socket (EPROMs may be shipped separately from the MVME162)
❏ 1MB Flash memory: either one Intel 28F008SA (for older boards) or four Intel 28F020s (for newer boards)
