Functional Description

EPROM

Four 44-pin PLCC/CLCC EPROM sockets for 27C102JK or 27C202JK type EPROMs. They are:

Organized in two 32-bit wide banks supporting 8-, 16-, and 32-bit read accesses

Controlled by the VMEchip2

Mapped to local bus address 0 following a local bus reset

ÐThis allows the MC88100 to start executing code at address 0 following a reset.

Programmable EPROM Features

Map decoder

Access time

When accessible at address 0

Static RAM

The MVME187 includes 128KB of 32-bit wide 100 ns static RAM (SRAM), which:

Supports 8-, 16-, and 32-bit wide accesses.

Allows debugger operation and execution of limited diagnostics without the DRAM mezzanine.

Is controlled by the VMEchip2; the access time is programmable.
