The Emerson / Motorola MVME120, MVME121, MVME122, and MVME123 VMEbus Microprocessor Modules offer a solution for high speed data processing, management, and control applications. The module contains an MC68010 MPU, MC68451 MMU, logical instruction cache, a serial debug terminal port, programmable tick timer, private ROM, and a large dynamic dual port RAM that may be loaded externally via the VMEbus. The MPU module, when used with a system controller module (such as the MVME050 system controller or the MVMEIIO CPU module), satisfies system requirements ranging from simple, high speed single processor applications to complex multiprocessor system architectures.
The Emerson Network Power / Motorola MVME210 / MVME214 is a VMEbus static RAM/ROM module for added memory (up to 16 Mb). This product provides 16 sockets for 24-/28-pin user supplied memory devices. The device access time is selectable from 100 to 400 ns. The MVME214 has a MVMX32bus interface. This unit is designed to be used with the MVME130/131.
The DPP is an I/O Channel-compatible dual printer interface module. ‘Ihis module confonns to the single-wide VME board fonn factor and connects to the I/O Channel with a 64-pin DIN standard connector. ‘Ihe DPP is used to expand the resources of an I/O Channel master to include two printer interfaces, one printer interface and a general-purpose 16-bit parallel data I/O port, or two general-purpose 16-bit parallel data I/O ports.
‘1-.o PIA’s (with buffers on their peripheral sides) are employed to implement the two parallel data ports. In addition to having an I/O Channel interface, each of the PIA’s is capable of driving up to two of the I/O Channel interrupt lines.
A front panel FAIL LED indicator is provided to indicate a module malfunction. The user must provide a connector-compatible I/O Channel backplane or ribbon cable for DPP connection to the I/O Channel master. Refer to the I/O Channel Specification Manual, ~torola publication number M68RIOCS, for interfacing and backplane information. ‘Ihe user must also provide compatible cables for DPP connection (via front panel connectors) to peripheral devices.
