I. Product Introduction

MVME167-034A is a 6U VME single-height industrial single-board computer from Motorola / Emerson. It belongs to the MVME167 series of 33MHz high-performance top-of-the-line models.

It is configured with a 33MHz main controller and 32MB large-capacity memory, making it the highest memory specification among the 33MHz versions of this series. The entire board's pins, structure, interfaces are fully hardware compatible with the 031A/032A/033A and all B versions of the same series, and can be directly replaced for general use.

It is suitable for multi-tasking operation, complex calculations, large data caching, and high-load working conditions in VME bus industrial control systems.

II. Parameters

1. Processor

The MC68040RC33 processor is adopted, with a main frequency of 33 MHz, a 32-bit architecture, a built-in hardware floating-point unit FPU, 8KB of first-level cache, and a memory management unit MMU. The overall computing, real-time control, and floating-point processing performance is superior to that of the 25 MHz series models.

2. Memory and Storage

The board is equipped with 32MB 32-bit DRAM with parity check, which reaches the capacity limit and does not require expansion; it is also equipped with 128KB battery-backed SRAM, which automatically saves configurations and running data upon power loss; a 44-pin PLCC firmware slot is reserved, supporting firmware solidification; an integrated battery-backed NVRAM real-time clock does not lose data upon power loss.

3. Built-in Interfaces

It comes with a single 10Mbps Ethernet interface, supporting both 10BASE-T and AUI access methods; it is equipped with 4 EIA-232-D serial ports, including 1 debugging console port, 3 user communication ports, with a maximum baud rate of 115200bps; it has a single SCSI-2 single-ended interface with DMA high-speed transmission, a maximum of 20MB/s, and can be connected to up to 7 SCSI storage peripherals; it has 1 IEEE1284 bidirectional parallel interface; the VME bus supports A32/D32 transmission mode, can be used as a master device, slave device, or system controller; it has multiple programmable timers and hardware watchdogs for system automatic reset protection.

4. Electrical and Environmental

The power supply is DC + 5V, with a typical working current of 4.0A and a maximum of 5.0A; the standard operating temperature is 0℃ to +55℃, and the storage temperature is -55℃ to +125℃; it uses forced air cooling by the chassis, with a standard power consumption of approximately 20W.

5. Structural Specifications

Standard 6U single-height VME size, the overall weight is approximately 0.7kg, and it is compatible with general VME chassis rails for installation.

III. Series Positioning

MVME167 33MHz A Version Memory Hierarchy:

031A is 4MB, 032A is 8MB, 033A is 16MB, 034A is 32MB as the top configuration.

IV. Application Scenarios

Industrial automation main control, complex motion control, on-site big data collection, embedded multi-task industrial control, and VME devices requiring a 33MHz high main frequency and 32MB large memory for high-load operation.
