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

I. Basic Details

Model: MVME162P-344 (MVME162PA-344)

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, High Expansion Standard Type

II. Core Hardware (344 Key: 33 MHz with hardware floating-point FPU)

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

32-bit, 8KB L1 cache, MMU, hardware floating-point arithmetic unit ✅

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 (344 Standard: 4IP + Dual Networks + SCSI Full Configuration)

✅ Dual 10Mbps Ethernet (DMA)

✅ 2× Serial Ports (EIA-232-D, Console + User)

✅ 4× IndustryPack (IP) Expansion Slots (Independent DMA)

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

✅ 6× 32-bit Timers + Watchdog

IV. Power Consumption and Environment (344 = Commercial Standard Temperature, no E/S suffix)

Power Supply: +5V, typical 2.3A

Operating Temperature: 0°C ~ +70°C (Commercial / Industrial Standard Temperature)

Hardening / Wide Temperature: None (requires wide temperature selection 344E; hardening selection 344SE)

Size: 6U VME (233.4 × 160 mm)

Weight: Approximately 0.9 kg

V. Comparison of 344 Family (344 / 344E / 344SE)

344: MC68040 (with FPU), 16MB, 0~+70°C Commercial Temperature, 4IP, Dual Networks, SCSI, Standard Model ✅

344E: MC68040 (with FPU), 16MB, -40~+85°C Wide Temperature, 4IP, Dual Networks, SCSI, Wide Temperature Model

344SE: MC68040 (with FPU), 16MB, -40~+85°C Wide Temperature + Hardening, 4IP, Dual Networks, SCSI, Hardening Top Configuration

One-sentence summary: 344 = Commercial with Floating Point, 344E = Wide Temperature, 344SE = Wide Temperature + Hardening.

VI. 344 vs 244LSE / 252SE (Common Selection Comparison)

344: 33 MHz with FPU, 4×IP, Dual Ethernet, SCSI, Commercial Temperature, Standard Model

244LSE: 25 MHz without FPU, 4×IP, Dual Ethernet, SCSI, Wide Temperature + Hardening

252SE: 25 MHz with FPU, 2×IP, Single Ethernet, SCSI, Wide Temperature + Hardening

→ Select 344: Need 33 MHz High Performance Floating Point + 4IP + Dual Networks + Commercial Temperature Low Cost

VII. Typical Applications (344 Exclusive Scenarios)

Factory Automation, Motion Control, Algorithm Simulation (requires hardware floating-point)

Laboratories, Computer Rooms, Industrial Control Rooms (0~70°C Environment)

Need 4IP Expansion + Dual Network Redundancy + SCSI Local Storage

Pursuing 33 MHz High Performance, Budget Priority, No Wide Temperature / Hardening Required

VIII. Compatibility Replacement

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

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