MVME162‑813

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162

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

Positioning: 8MB DRAM + single Ethernet + no SCSI + 4×IP slots (standard expansion type)

I. Core Hardware

Processor: MC68LC040, 25 MHz, 32-bit

With 8KB cache + MMU, no FPU (floating point)

Memory DRAM: 8MB (with parity check)

Battery backup SRAM: 512KB (power-off retention)

Flash Memory: 1MB (162Bug firmware)

Real-time Clock: with battery backup

II. On-board I/O (Key points: Single network, no SCSI, 4IP)

✅ Single 10Mbps Ethernet (DMA)

✅ Dual serial ports

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

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

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

❌ No SCSI interface

One sentence: The interface configuration is exactly the same as 723, except that the CPU is LC040 (without floating-point) and the memory is 8MB.

III. Bus and Mechanical

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

Form: Standard 6U VME dual-height single board

Power supply: +5V, typical 3.0A

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

IV. Comparison of Key Models in the Same Series (Quickly Differentiate)

MVME162-533A: 040 (with floating-point), 16MB, single network + SCSI + 4IP

MVME162-723: 040 (with floating-point), 8MB, dual network + no SCSI + 4IP

MVME162-743: 040 (with floating-point), 16MB, dual network + no SCSI + 4IP

MVME162-763: 040 (with floating-point), 16MB, dual network + SCSI + 2IP

MVME162-813: LC040 (without floating-point), 8MB, single network + no SCSI + 4IP

One sentence: 813 = 723's "without floating-point + single network" low-cost version, with 4IP expansion retained.

V. Typical Applications

Industrial control, DCS, PLC (no need for floating-point operations)

Data acquisition, general automation (8MB is sufficient)

VME systems require 4 IP expansions, budget-sensitive

Single network port, no hard disk storage, seeking stable and low-cost scenarios

VI. Compatibility and Replacement

Same series can be directly interchanged: 162-223/530/531/532/533A/723/743/763/813

Key differences: Whether the CPU has FPU, memory size, number of network ports, presence of SCSI, number of IP expansions
