MVME162‑743

Brand: Motorola (Motorola) / Emerson (Emerson) / Abaco Systems

Series: MVME162

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

Position: MVME162 Dual Network Interface Top-of-the-Line Version: 16MB + Dual Ethernet + 4×IP + No SCSI

I. Core Hardware (Top-of-the-Line)

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

Memory DRAM: 16MB FPM, with parity (the largest in the series, the same as 533A)

Battery Backup SRAM: 512KB (data retention even when power is off)

Flash Memory: 1MB (firmware / 162Bug monitoring program)

Real-Time Clock: with battery backup

II. On-board I/O (Key points: Dual network ports + 16MB)

✅ Dual 10Mbps Ethernet (DMA) - The most distinctive feature of 743: Dual network ports + 16MB large memory

✅ Dual serial ports

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

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

✅ 4 IndustryPack (IP) expansion slots (each slot with DMA)

❌ No SCSI interface (like 723, opposite to 533A)

III. Bus and Mechanical

Bus: VMEbus A32/D64, master/slave mode, can be used as a system controller

Form: Standard 6U VME board (double high)

Power supply: +5V, typical 3.5A

Temperature: 0°C ~ 70°C (industrial-grade wide temperature range)

IV. Differences from models of the same series (easy to understand at a glance)

MVME162-723: 8MB + Dual network ports + No SCSI

MVME162-743: 16MB + Dual network ports + No SCSI ( = 723 + 16MB)

MVME162-533A: 16MB + Single network port + SCSI

Sentence: 743 = 723 with larger memory version, dual network redundancy + 16MB, suitable for network-intensive, large data volume, dual network isolation / redundancy scenarios.

V. Typical Applications

Industrial DCS, PLC control systems

Dual Ethernet redundancy / network isolation (743 is the main feature)

Embedded real-time control, data acquisition (large memory)

VME bus automation, test and measurement systems

Requires dual network ports + large memory + multiple IP expansion for high-end VME systems
