MVME162P-244LE | Basic Information (Motorola / Emerson / Abaco)

I. Basic Details

Model: MVME162P-244LE (MVME162PA-244LE)

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162P (6U VME High-Performance SBC)

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

Positioning: 25 MHz LC040 (No Floating Point), 16MB, Dual Ethernet, 4× Serial Ports, 4× IP, SCSI, Low Power Consumption, Wide Temperature Range

II. Core Hardware (Only differs from 244L in the presence or absence of a floating-point unit in the CPU)

CPU: MC68LC040, 25 MHz (low power consumption, without FPU)

32-bit, 8KB cache, MMU, no hardware floating-point (LC = Low-Cost / Low-Power)

DRAM: 16MB (parity check)

SRAM: 512KB (battery backup, retains data when power is off)

Flash: 1MB (162Bug firmware)

RTC/NVRAM: 8K×8, battery-backed clock

III. Onboard I/O (Same as 244L: 4IP + SCSI high-end configuration)

✅ Dual 10Mbps Ethernet (DMA)

✅ 4× Serial Ports (EIA-232-D, time-division multiplexing)

✅ 4× IndustryPack (IP) expansion slots (each channel independent DMA)

✅ SCSI-2 interface (NCR 53C710, with DMA)

✅ 6× 32-bit Timers + Watchdog

IV. Power Consumption and Environment (L = Low power consumption, E = Enhanced / 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 0.88 kg

V. Instant Comparison of the 244 Family (Key Difference: Presence or Absence of Floating-Point Unit in the CPU)

244L: MC68040 (with FPU), 16MB, low power consumption, -40~+85°C, 4IP, SCSI

244LE: MC68LC040 (without FPU), 16MB, low power consumption, -40~+85°C, 4IP, SCSI ✅

→ 244LE = 244L with reduced floating-point unit, unchanged wide temperature range and high expansion

VI. Typical Applications (Exclusive scenarios for 244LE)

Harsh wide temperature (-40~+85°C) + Multiple I/O expansion + No need for floating-point

Railway transportation, vehicle-mounted, ship-mounted, industrial control (no complex calculations)

Requires 4 IP modules + local SCSI storage + dual network redundancy

Low power consumption, high reliability, long-term unmanned system

VII. Compatibility and Replacement

Interchangeable within the same series: 244LE / 244L / 244LSE / 242L/LE/LSE

Upward compatible: MVME162-530/743/853/863
