MVME162PA-242L | Basic Information (Motorola / Emerson / Abaco)

I. Basic Details

Model: MVME162PA-242L

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162PA (6U VME Single Board Computer, 242 rugged version)

Form: 6U VME Dual High SBC

Positioning: 25MHz with FPU, 8MB, 2IP, single Ethernet, no SCSI, 0 - +70°C, rugged (anti-vibration / reinforced)

II. Core Hardware (Same as 242 Standard Version: 25 MHz with FPU, 8MB)

CPU: MC68040, 25 MHz (with FPU hardware floating point)

DRAM: 8MB (parity check)

SRAM: 512KB (battery backup, power-off retention)

Flash: 1MB (162Bug firmware)

RTC/NVRAM: 8K×8, battery backup clock

III. Board-Supported I/O (Same as 242 Standard Version: 2IP + single network + dual serial ports, no SCSI)

✅ Single 10Mbps Ethernet (DMA)

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

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

❌ No SCSI interface (242 full series does not have SCSI; select 344 series for SCSI)

✅ 6× 32-bit Timers + Watchdog

IV. Environment and Suffix (L = ruggedized; without E = standard temperature)

Power Supply: +5V, typical 2.0A

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

Ruggedization: ✅ Yes (anti-vibration, strengthened welding/structure, suitable for vibration environments)

Wide Temperature: ❌ No (select 242E/242SE for wide temperature)

Size/Weight: 6U VME, approximately 0.85kg

V. 242 Family Suffix Quick Reference (Easy to distinguish at a glance)

242: 0~+70°C, no ruggedization, no SCSI → Basic Standard Version

242L: 0~+70°C, ruggedization, no SCSI → Standard Temperature Ruggedized Version (This is your model)

242E: -40~+85°C, no ruggedization, no SCSI → Wide Temperature Version

242SE: -40~+85°C, ruggedization, no SCSI → Wide Temperature Ruggedized Top Configuration

Rule of Thumb: E = Wide Temperature, S = Ruggedization, L = Ruggedization (old standard); 242 full series has no SCSI

VI. Differences between 242L and 242 Core (Commonly Asked by Customers)

242: 0~+70°C, ordinary indoor / data center, no anti-vibration

242L: 0~+70°C + ruggedization and anti-vibration, vibration equipment / vehicle-mounted (normal temperature), high-reliability cabinet

VII. Typical Applications

Industrial vibration equipment, production lines, machine tools, robots (normal temperature vibration)

Vehicle / ship-mounted (normal temperature environment, no need for wide temperature), high-reliability data center

Cost-sensitive, no SCSI, no 4IP, no wide temperature

Basic motion control, data acquisition, general embedded systems

VIII. Compatibility and Replacement

Interchangeable within the same series: 242 / 242L / 242E / 242SE

Upward Compatibility: MVME162P-252 / 344 series (note differences in SCSI / network ports)
