MVME162P-244L | Basic Information (Motorola / Emerson / Abaco) I. Basic Information

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

Brand: Motorola / Emerson / Abaco Systems

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

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

Positioning: 25 MHz 040 (Floating Point), 16MB, Dual Ethernet, 4× Serial Ports, 4× IP, SCSI, Low Power Consumption, Wide Temperature Range

II. Core Hardware (The biggest difference between 244 and 242: 4×IP + SCSI)

CPU: MC68040, 25 MHz (low power version)

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

DRAM: 16MB (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 (High-end configuration for 244: 4IP + SCSI, 242 only has 2IP, no SCSI)

✅ Dual 10Mbps Ethernet (DMA)

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

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

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

✅ 6×32-bit Timers + Watchdog

IV. Power Consumption and Environment (L = Low Power + Extended Temp)

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

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 244 and 242 Families (Key Differences)

242L: 16MB, low power, -40~+85°C, 2×IP, no SCSI

244L: 16MB, low power, -40~+85°C, 4×IP, with SCSI ✅

→ 244L = High-extended version of 242L: 2 more IP slots + disk SCSI

VI. Typical Applications (Exclusive scenarios for 244L)

Harsh industrial wide temperature (-40~+85°C) + multiple I/O expansion

Need 4 IP modules (analog / digital / communication card)

Need local disk / optical drive (SCSI) VME system

Railway transportation, vehicle-mounted, ship-mounted, military measurement and control (non-classified)

Floating point operation + dual network redundancy + high-reliability real-time control

VII. Compatibility and Replacement

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

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