Brand: Motorola / Emerson / Abaco Systems

Series: MVME162

Type: 6U VME bus single-board computer (SBC)

Positioning: Dual Ethernet + SCSI + 16MB DRAM + 2 IP slots (not 4 slots)

I. Core Hardware

Processor: MC68040, 25 MHz, 32-bit, FPU (floating point) + MMU + 8KB cache

Memory DRAM: 16MB (with parity)

Battery backup SRAM: 128KB (battery backup)

Flash Memory: 1MB (firmware / monitoring)

Real-time Clock: With battery backup

II. On-board I/O (Key Differences: Dual Network Ports + SCSI + 2×IP)

✅ Dual 10Mbps Ethernet (DMA)

✅ SCSI interface (narrowband, DMA) - The 763 model is the only one with SCSI among the dual network ports

✅ Dual serial ports

Serial Port 1: Console (EIA-232-D)

Serial Port 2: EIA-232 / 422 (optional)

✅ 2 IndustryPack (IP) expansion slots - Note: Only 2, not 4

III. Bus and Mechanical

Bus: VMEbus A32/D64, Master/Slave, can be used as a system controller

Form: Standard 6U VME dual high single board

Power Supply: +5V, typical 3.5A, maximum 4.5A

Temperature: 0°C ~ 70°C (industrial grade)

IV. Comparison within the Series (Quick Differentiation)

MVME162-533A: 16MB, single network port + SCSI + 4IP

MVME162-723: 8MB, dual network ports + no SCSI + 4IP

MVME162-743: 16MB, dual network ports + no SCSI + 4IP

MVME162-763: 16MB, dual network ports + SCSI + 2IP (= 533A + dual network ports - 2IP)

One sentence: 763 = Dual Network Port Version 533A, but with half the IP slots (2), while retaining SCSI.

V. Typical Applications

VME system requiring dual network redundancy + SCSI storage

Industrial DCS, PLC, data acquisition (with local storage)

Network isolation + hard disk / optical drive expansion scenarios

Projects with limited space and not requiring 4 IP slots

VI. Compatibility and Replacement

Interchangeable within the same series: 162-223/530/531/532/533A/723/743/763

Core Differences: Memory, number of network ports, SCSI, number of IP slots
