MVME162P-344SE | Basic Information (Motorola / Emerson / Abaco)

I. Basic Details

Model: MVME162P-344SE (MVME162PA-344SE)

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162P (6U VME Single Board Computer)

Form: 6U VME Dual High SBC

Positioning: 33MHz 68040 (with FPU), 16MB, Dual Ethernet, 4×IP, SCSI, Wide Temperature + Robust, Flagship Top-of-the-Line Model ✅

II. Core Hardware (Top-of-the-line for the entire series: 33 MHz with hardware floating-point FPU + 16MB)

CPU: MC68040, 33 MHz (with FPU hardware floating-point)

32-bit, 8KB L1, MMU, 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. On-board I/O (Most comprehensive for the entire series: 4IP + dual networks + SCSI fully equipped)

✅ Dual 10Mbps Ethernet (DMA)

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

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

✅ SCSI-2 interface (NCR 53C710, DMA)

✅ 6× 32-bit timers + watchdog

IV. Environment and Hardening (SE = wide temperature + hardening, the most stringent conditions)

Power supply: +5V, typical 2.3A

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

Hardening: Yes (anti-vibration, anti-shock, three-proof reinforcement ✅)

Wide temperature: Yes ✅

Size: 6U VME (233.4 × 160 mm)

Weight: Approximately 0.9 kg

V. Ultimate Comparison of 344 Series (Immediately distinguish 344 / 344S / 344E / 344SE)

344: 0~+70°C, no hardening → standard commercial type

344S: 0~+70°C, hardening → standard temperature hardening type

344E: -40~+85°C, no hardening → wide temperature type

344SE: -40~+85°C, hardening ✅ → wide temperature + hardening top configuration (your model)

Rule of thumb: E = wide temperature, S = hardening, SE = all have

VI. Typical Applications of 344SE (Only this model can cover the scenarios)

Outdoor / Vehicle-mounted / Ship-mounted / Rail transportation (wide temperature -40~+85°C)

Equipment compartments with strong vibration and shock, military, mobile platforms (hardening)

Factory automation, motion control, algorithm simulation (33 MHz floating-point)

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

Budget sufficient, need the most stable and all-around, long-term operation in harsh environments

VII. Compatibility and Replacement

Same series interchangeable: 344 / 344S / 344E / 344SE / 244/252 series

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