Series: MVME162PA (6U VME SBC, 242 wide-temperature cooling, non-hardened)

Form: 6U VME dual high single-board computer

Positioning: **25MHz FPU, 8MB, 2IP, single Ethernet, no SCSI, -40~+85°C, wide temperature, original factory heat sink, non-hardened

II. Core Hardware (Same as 242 Full Series)

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. Built-in I/O (Same as 242 Full Series: 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)

✅ 6× 32-bit Timers + Watchdog

IV. Environment and Suffix (S = Wide Temperature, E = Enhanced / Cooling; L = Non-Rugged)

Power Supply: +5V, Typical 2.0A

Operating Temperature: -40°C ~ +85°C (Industrial Wide Temperature ✅)

Ruggedness: ❌ Standard Soldering, Not Resistant to Strong Vibration (Non-Rugged)

Cooling: ✅ Original Factory with Metal Heat Sink (SE Standard)

Wide Temperature: ✅ Supports Low / High Environments in Harsh Conditions

Size / Weight: 6U VME, Approximately 0.9kg (Including Heat Sink)

V. 242 Family Suffix Mnemonic (SE/LE/LSE/LNS Comparison)

242: 0~+70°C, Non-Rugged, No Cooling → Standard Version

242L: 0~+70°C, Rugged, No Cooling → Normal Temperature Rugged

242E: -40~+85°C, Non-Rugged, No Cooling → Wide Temperature

242LE: -40~+85°C, Rugged, No Cooling → Wide Temperature Rugged

242SE: -40~+85°C, Non-Rugged, With Heat Sink → Wide Temperature Cooling (This Model)

242LSE: -40~+85°C, Rugged, With Heat Sink → Wide Temperature Rugged Cooling

242LNS: Same as LSE (Manufacturer Naming Difference, Rugged + Cooling)

Rule: L = Rugged, S = Wide Temperature, E = Cooling; No L = Non-Rugged; 242 Full Series has no SCSI

VI. Core Differences between SE and LSE/LE (Commonly Asked by Customers)

242SE: Wide Temperature + Non-Rugged + Heat Sink → Suitable for High Temperature / Enclosed, Low Vibration Situations

242LE: Wide Temperature + Rugged + No Cooling → Suitable for High Vibration, Non-extreme Temperature Situations

242LSE: Wide Temperature + Rugged + Heat Sink → Suitable for High Vibration + High Temperature Harsh Situations

VII. Typical Applications

Industrial Control, High Temperature Cabinets, Air-condition-free Computer Rooms (Wide Temperature + Cooling Priority)

Laboratories, Instrumentation, Communication Equipment (Wide Temperature, Low Vibration)

Equipment requiring wide temperature and cooling, but not resistant to strong vibration

Equipment without SCSI, without 4IP,主打 wide temperature cooling mid-range demand

VIII. Compatibility and Replacement

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

Upward Compatibility： MVME162P-252 / 344 Series (Note： SCSI / Network Port Differences)
