MVME167-33B

1. MVME167-33B Core Specifications

The MVME167-33B is a double-high VMEmodule based on the MC68040 microprocessor. Its key hardware configurations and interfaces are as follows:

Memory:
- 4/8/16/32/64 MB of parity-protected DRAM, or 4/8/16/32/64/128/256 MB of ECC-protected DRAM.
- 8 KB of static RAM with a time-of-day clock (equipped with battery backup).
- 128 KB of static RAM (optional battery backup available).
- Four ROM sockets.
Interfaces:
- Ethernet transceiver interface.
- Four serial ports with EIA-232-D interface.
- SCSI bus interface with DMA.
- Centronics printer port.
- A16/A24/A32/D8/D16/D32/D64 VMEbus master/slave interface.
- VMEbus system controller.
Timers: Four tick timers and one watchdog timer.

2. I/O Connection & Transition Board Support

The MVME167-33B
’s I/O is connected to the VMEbus P2 connector. The main board links to transition boards via a P2 transition board and cables.
Supported transition boards: MVME712-12, MVME712-13, MVME712M, MVME712A, MVME712AM, and MVME712B. These boards are collectively referred to as MVME712X in this manual, unless specified separately.
Function of MVME712X: Provide configuration headers and industry-standard connectors for I/O devices.

3. Key ASIC Functions

3.1 VMEchip2

The VMEbus interface is implemented by the VMEchip2 ASIC, which integrates the following components:

Two tick timers and one watchdog timer.
Programmable map decoders for master and slave interfaces.
VMEbus-to-local bus and local bus-to-VMEbus DMA controllers.
VMEbus-to-local bus and local bus-to-VMEbus non-DMA programmed access interfaces.
VMEbus interrupter, system controller, interrupt handler, and requester.
Data Transfer Specifications:
- Processor-to-VMEbus transfers: Support D8, D16, or D32.
- VMEchip2 DMA transfers to VMEbus: Support D16, D32, D16/BLT, D32/BLT, or D64/MBLT.

3.2 PCCchip2

The PCCchip2 ASIC provides:

Two tick timers.
Interfaces to the LAN chip, SCSI chip, serial port chip, printer port, and BBRAM (Battery-Backed RAM).

3.3 MEMC040 & MCECC

MEMC040: A memory controller ASIC that provides a programmable interface for the parity-protected DRAM mezzanine board.
MCECC: A memory controller ASIC that provides a programmable interface for the ECC-protected DRAM mezzanine board.

4. Equipment Required for Complete System

To build a complete system using the MVME167-33B, the following equipment is required:

Terminal
Disk drives and their corresponding controllers
One MVME712X transition module (MVME712-12, MVME712-13, MVME712M, MVME712A, MVME712AM, or MVME712B), plus matching connecting cables and a P2 adapter
Compatible operating system

5. MVME167-33B Bug Debug Monitor Firmware

Installation: The MVME167-33B Bug (referred to as “167Bug”) debug monitor firmware is pre-installed in 2 of the 4 EPROM sockets on the MVME167 main module.
Core Functions:
- Offers over 50 commands for debugging, upline/downline loading, and disk bootstrap loading.
- Includes a full set of onboard diagnostics and a one-line assembler/disassembler.
- Features a user interface that accepts commands from the system console terminal.
- Supports System Mode, which provides options from a service menu.
Reference Documentation: For detailed operations, refer to the MVME167-33BBug Debugging Package User’s Manual and the Debugging Package for Motorola 68K CISC CPUs User’s Manual.

6. MVME712X Transition Module & Software Support
