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

Model: MVME162P-242L (MVME162P242L)

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162P (Reduced-Profile High-Performance 6U VME System-on-a-Board)

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

Positioning: **25 MHz 040 (with floating point), 4MB, dual Ethernet, 4× serial ports, 2× IP, no SCSI, low power / industrial wide-temperature version

II. Core Hardware (Key: Low Power + Wide Temperature)

CPU: MC68040, 25 MHz (Low Power Version)

32-bit, 8KB cache, MMU, FPU (Hardware Floating Point)

DRAM: 4MB (Parity Check) (Same as 242, lower than 242E)

SRAM: 128KB (Battery Backup)

Flash: 1MB (162Bug Firmware)

RTC/NVRAM: 8K×8, Battery Backup Clock

III. Onboard I/O (Exactly the same as 242/242E)

IV. Power Consumption and Environment (L = Low Power / Wide Temperature)

Power Supply: +5V, Typical 2.0A (Lower by ~1A compared to 242/242E)

Operating Temperature: -40°C ~ +85°C (Industrial Wide Temperature)

(242/242E is 0°C ~ +70°C)

Size: 6U VME (233.4 × 160 mm)

Weight: Approximately 0.8 kg

V. 242 / 242E / 242L Side-by-Side Comparison

MVME162P-242: 4MB, Standard Power Consumption (3A), 0~70°C

MVME162P-242E: 16MB, Standard Power Consumption (3A), 0~70°C

MVME162P-242L: 4MB, Low Power Consumption (2A), -40~+85°C

L = Low Power + Extended Temperature (Same as 242), Memory is the same.

VI. Typical Applications

Low Temperature / High Temperature Industrial Sites (-40°C Cold Storage, +85°C High Temperature Cabinet)

Low Power VME System (Limited Backplane Power Supply, Multiple Slots)

Industrial Control Requires Floating Point + Dual Network + 2IP + Wide Temperature

VII. Compatibility and Replacement

Interchangeable within the same series: MVME162P-242L / 242 / 242E (Note: Power Consumption and Temperature)

Upward Compatibility: MVME162-223/530/743/853
