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

I. Basic Details

Model: MVME162PA-242LE

Brand: Motorola / Emerson / Abaco Systems

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

Form: 6U VME dual-high SBC

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

II. Core Hardware (Same as 242 Series: 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 Series: 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 Series does not have SCSI; select 344 Series for SCSI)

✅ 6× 32-bit timers + watchdog

IV. Environment and Suffix (L = rugged, E = wide temperature → LE = wide temperature rugged)

Power supply: +5V, typical 2.0A

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

Rugged: ✅ (anti-vibration, strengthened welding / structure, vibration environment dedicated)

Wide temperature: ✅ (low temperature / high temperature harsh environment)

Size / Weight: 6U VME, approximately 0.85kg

V. 242 Family Suffix Mnemonic (Quickly Differentiate)

242: 0~+70°C, no ruggedness, no SCSI → Basic standard version

242L: 0~+70°C, rugged, no SCSI → Standard temperature rugged version

242E: -40~+85°C, no ruggedness, no SCSI → Wide temperature version

242LE: -40~+85°C, rugged + wide temperature, no SCSI → Wide temperature rugged top configuration (your model)

242SE: Same as 242LE (late standard version, fully compatible)

Phrase: E = wide temperature, L/S = rugged, LE = wide temperature rugged; 242 Series has no SCSI

VI. Core Differences between 242LE and 242/242L/242E (Commonly Asked by Customers)

242: Normal temperature (0~70°C), no ruggedness → Ordinary data center

242L: Normal temperature (0~70°C), rugged → Normal temperature vibration equipment

242E: Wide temperature (-40~85°C), no ruggedness → Outdoor / Temperature fluctuation large

242LE: Wide temperature (-40~85°C) + rugged → Harsh environment + vibration (vehicle / ship / outdoor industrial)

VII. Typical Applications

Vehicle / ship / rail transit (wide temperature + vibration dual harsh conditions)

Outdoor equipment, field cabinets, high-temperature / low-temperature workshop without air conditioning

High-reliability industrial control, vibration equipment, machine tools, robots (wide temperature scenarios)

No SCSI, no 4IP, but high-end requirement of wide temperature + rugged

VIII. Compatibility and Replacement

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

Upward compatible: MVME162P-252 / 344 Series (note differences in SCSI / network ports)
