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

I. Basic Details

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

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, Commercial Temperature, Robust Type

II. Core Hardware (Same as 344/344E, 33 MHz with hardware floating-point FPU)

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

DRAM: 16MB (parity check)

SRAM: 512KB (battery backup)

Flash: 1MB (162Bug firmware)

RTC/NVRAM: 8K×8, battery backup clock

III. Built-in I/O (Same as the entire 344 series: 4IP + dual network + full high configuration)

✅ Dual 10Mbps Ethernet (DMA)

✅ 2× Serial Ports (EIA-232-D)

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

✅ SCSI-2 interface (NCR 53C710, DMA)

✅ 6× 32-bit timers + watchdog

IV. Environment and Toughening (S = toughening, temperature same as 344: 0~+70°C)

Power supply: +5V, typical 2.3A

Operating temperature: 0°C ~ +70°C (commercial / industrial standard temperature)

Toughening: Yes (suffix S: shock resistance, impact resistance, three-proof reinforcement)

Wide temperature: No (for wide temperature select 344E; wide temperature + toughening select 344SE)

Size / Weight: 6U VME, approximately 0.9 kg

V. Quick Reference for 344 Family (temperature + toughening differences)

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

344S: 0~+70°C, toughening ✅, toughening standard temperature type (this is your current one)

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

344SE: -40~+85°C, toughening ✅, wide temperature toughening top configuration

One-word mnemonic:

E = Wide temperature

S = Toughening

SE = Wide temperature + toughening

No suffix = Standard temperature + no toughening

VI. Typical Applications of 344S

Indoor industrial control, computer rooms, control rooms (0~70°C environment)

Cabinets with large vibration / shock, assembly lines, equipment compartments (requires toughening)

Need 33MHz floating-point + 4IP + dual network redundancy + SCSI

No wide temperature, but need shock resistance and toughening, medium budget

VII. Compatibility and Replacement

Interchangeable within the same series: 344 / 344S / 344E / 344SE / 244/252 series

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