MVME162P-242LE | Basic Information (Motorola / Emerson / Abaco) I. Basic Information

Model: MVME162P-242LE (MVME162P242LE)

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162P (6U VME Compact High-Performance System Board)

Form: 6U VME Dual High-Performance Single-Board Computer

Positioning: 25 MHz 040 (with floating point), 16MB, dual Ethernet, 4× serial ports, 2× IP, no SCSI, low power consumption, industrial wide temperature range

II. Core Hardware (The strongest combination of 242 family: 16MB + wide temperature range + low power consumption)

CPU: MC68040, 25 MHz (low power consumption version)

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

DRAM: 16MB (parity check) (same as 242E, 4 times larger than 242/242L)

SRAM: 128KB (battery backup, power-off retention)

Flash: 1MB (162Bug firmware)

RTC/NVRAM: 8K×8, battery backup clock

III. Built-in I/O (Completely consistent with 242/242E/242L)

✅ Dual 10Mbps Ethernet (DMA)

✅ 4× Serial ports (EIA-232-D, time-sharing)

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

✅ 6× 32-bit timers + watchdog

❌ No SCSI interface

IV. Power Consumption and Environment (L characteristics: low power consumption + wide temperature range)

Power supply: +5V, typical 2.0A (low power consumption)

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

Size: 6U VME (233.4 × 160 mm)

Weight: Approximately 0.8 kg

V. Easily distinguishable 242 family (Key differences)

242: 4MB, standard power consumption, 0~70°C

242E: 16MB, standard power consumption, 0~70°C

242L: 4MB, low power consumption, -40~+85°C

242LE: 16MB, low power consumption, -40~+85°C (top configuration combination)

One-sentence definition: 242LE = 242E (16MB) + 242L (low power consumption wide temperature range).

VI. Typical Applications

High-temperature / low-temperature harsh environments (-40°C to +85°C)

Limited power supply on VME system backplane, multi-slot low power consumption requirements

Need floating point + dual networks + 2IP + 16MB large memory + wide temperature for industrial control

Real-time control, data acquisition, lightweight algorithms, redundant network

VII. Compatibility and Replacement

Direct interchange within the same series: 242LE / 242L / 242E / 242

Upward compatibility: MVME162-223/530/743/853/863
