MVME162PA-242E | Basic Information (Motorola / Emerson / Abaco)

I. Basic Details

Model: MVME162PA-242E

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162PA (6U VME single-board computer, 242 wide-temperature model)

Form: 6U VME dual-high SBC

Positioning: 25MHz with FPU, 8MB, 2IP, single Ethernet, no SCSI, wide-temperature -40~+85°C, no ruggedization

II. Core Hardware (Same as 242 Standard Edition, 25 MHz with FPU, 8MB)

CPU: MC68040, 25 MHz (with FPU hardware floating point)

DRAM: 8MB (parity check)

SRAM: 512KB (battery backup, power-off retention)

Flash: 1MB (162Bug firmware)

RTC/NVRAM: 8K×8, battery backup clock

III. Built-in I/O (Same as 242 Standard Edition: 2IP + single network + dual serial ports, no SCSI)

✅ Single 10Mbps Ethernet (DMA)

✅ 2× Serial ports (EIA-232-D, console + user)

✅ 2× IndustryPack (IP) expansion slots (independent DMA)

❌ No SCSI interface (242 full series does not have SCSI; select 344 series for SCSI)

✅ 6× 32-bit timers + watchdog

IV. Environment and Suffix (E = wide temperature; no S = no ruggedization)

Power supply: +5V, typical 2.0A

Operating temperature: -40°C ~ +85°C (industrial wide temperature ✅)

Ruggedization: None (standard version structure, no shock resistance enhancement)

Wide temperature: Yes ✅

Size / Weight: 6U VME, approximately 0.85kg

V. 242 Family Suffix Quick Reference (Easy to distinguish at a glance)

242: 0~+70°C, no ruggedization, no SCSI → Basic Standard Edition

242L: 0~+70°C, ruggedized, no SCSI → Standard Temperature-Rugged Edition

242E: -40~+85°C, no ruggedization, no SCSI → Wide Temperature Edition (This is your model)

242SE: -40~+85°C, ruggedized, no SCSI → Wide Temperature Rugged Top-End Edition

Rule of Thumb: E = wide temperature, S = ruggedization, L = ruggedization (old standard); 242 full series has no SCSI

VI. Differences between 242E and 242 Core (Commonly asked by customers)

242: 0~+70°C, indoor / data center use, cheaper

242E: -40~+85°C, outdoor / harsh environments (such as low temperature / high temperature), slightly higher price

VII. Typical Applications

Outdoor equipment, vehicle-mounted / ship-mounted, rail transportation (large temperature fluctuations)

Factory high/low temperature workshops, air-conditioning-free cabinets

Cost-sensitive, no SCSI, no 4IP, no ruggedization

Basic motion control, data acquisition, general embedded systems

VIII. Compatibility and Replacement

Interchangeable within the same series: 242 / 242L / 242E / 242SE

Upward compatibility: MVME162P-252 / 344 series (note differences in SCSI / network ports)
