MVME162PA-244LE | Basic Information (Motorola / Emerson / Abaco)

I. Basic Details

Model: MVME162PA-244LE

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162PA (6U VME SBC, 244 = 4IP + Dual Network Series)

Form: 6U VME Dual High Single Board Computer

Positioning: 25 MHz 68LC040 (without FPU), 16MB, 4×IndustryPack, Dual Ethernet, No SCSI, -40~+85°C wide temperature range, rugged anti-vibration, no heat sink

II. Core Hardware (Consistent across the 244 series)

CPU: MC68LC040, 25 MHz (No hardware FPU, 8KB cache + MMU)

DRAM: 16MB (Parity check)

SRAM: 512KB (Battery backup, power-on data retention)

Flash: 1MB (162Bug firmware)

RTC/NVRAM: 8K×8, battery-backed clock

III. Built-in I/O (Key features for 244: 4IP, dual networks, no SCSI)

✅ Dual 10Mbps Ethernet (DMA, redundant / dual networks)

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

✅ 4× IndustryPack (IP) expansion slots (each IP independent DMA) - 244's main difference

❌ No SCSI interface (244 series does not have SCSI)

✅ 6× 32-bit timers + watchdog

IV. Environment and Suffix (L = ruggedized, E = wide temperature; S = no cooling)

Power supply: +5V, typical 2.5A

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

Ruggedization: ✅ Reinforced welding, anti-vibration (vehicle-mounted / ship-mounted / rail)

Cooling: ❌ No original metal heat sink (reliant on chassis air duct)

Wide temperature: ✅ Supports harsh environments / extreme temperatures

Size / Weight: 6U VME, approximately 0.8kg (without heat sink)

V. 244 Family Suffix Mnemonic (including your model)

244: 0~+70°C, non-ruggedized, no cooling → Standard version

244L: 0~+70°C, ruggedized, no cooling → Normal temperature ruggedized

244E: -40~+85°C, non-ruggedized, no cooling → Wide temperature

244LE: -40~+85°C, ruggedized, no cooling → Wide temperature ruggedized (your model)

244LSE: -40~+85°C, ruggedized, with heat sink → Wide temperature ruggedized cooling

Rule of thumb: L = ruggedized, E = wide temperature, S = cooling; 244 = 4IP + dual networks + 16MB + no FPU

VI. 244LE vs 244L vs 242LE (Most frequently asked by customers)

244LE (your model): 4IP + dual networks + wide temperature (-40~+85°C) + ruggedized + no cooling → Harsh environment + multiple expansions

244L: 4IP + dual networks + normal temperature (0~70°C) + ruggedized + no cooling → High vibration, normal temperature

242LE: 2IP + single network + wide temperature + ruggedized + no cooling → Few expansions, single network, floating point optional
