MVME162‑863

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162

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

Position: 040 (with floating point), 16MB, dual Ethernet, with SCSI, 4×IP slots (full-function flagship version)

1. Core Hardware (Key Points: Floating point, 32 MHz, 16MB)

Processor: MC68040, 32 MHz

32-bit, 8KB cache + MMU + FPU (hardware floating point)

Memory DRAM: 16MB (with parity check)

Battery backup SRAM: 512KB (battery backup for power failure)

Flash Memory: 1MB (162Bug firmware)

Real-time Clock: With battery backup

II. On-board I/O (Full Interface: Dual Networks + SCSI + 4IP)

✅ Dual 10Mbps Ethernet (DMA)

✅ SCSI-2 interface (High-speed 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)

One sentence: The 162 series is the only model that simultaneously features "Dual Networks + SCSI + 4IP + Floating Point".

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 3.5A

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

IV. Comparison of Key Models in the Same Series (Quickly Differentiate 863 Position)

MVME162-813: LC040 (No Floating Point), 8MB, Single Network, No SCSI, 4IP

MVME162-833: LC040 (No Floating Point), 16MB, Single Network, No SCSI, 4IP

MVME162-853: LC040 (No Floating Point), 16MB, Dual Network, No SCSI, 4IP

MVME162-743: 040 (With Floating Point), 16MB, Dual Network, No SCSI, 4IP

MVME162-863: 040 (With Floating Point), 16MB, Dual Network, With SCSI, 4IP (Top Configuration)

One sentence: 863 = 743 + SCSI; 863 = 853 + Floating Point + SCSI.

V. Typical Applications (Requires Floating Point + Hard Disk + Dual Network Redundancy)

Industrial control, DCS, PLC (Requires Hardware Floating Point Calculation)

Data acquisition, with hard disk storage (SCSI connected to hard disk / CD-ROM)

Network redundancy system (Dual network ports for redundancy / isolation)

VME system requires 4 IP expansions, sufficient budget, full functionality requirements

Complex algorithms, real-time control, requires Floating Point + Storage + Redundant Network scenarios

VI. Compatibility and Replacement

Same series can be directly interchanged: 162-223/530/531/532/533A/723/743/763/813/833/853/863

Key differences: Whether CPU has FPU, Memory size, Number of network ports, Presence of SCSI, Number of IP slots
