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

I. Basic Details

Model: MVME162PA-242LSE

Brand: Motorola / Emerson / Abaco Systems

Series: MVME162PA (6U VME SBC, 242 wide-temperature ruggedized production version)

Form: 6U VME dual high single-board computer

Positioning: 25MHz FPU, 8MB, 2IP, single Ethernet, no SCSI, -40~+85°C, rugged, original factory metal heat sink (LSE = LE upgrade version / production standard)

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 (L = Encapsulation, S = Wide Temperature, E = Enhanced / Cooling)

Power Supply: +5V, Typical 2.0A

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

Encapsulation: ✅ Anti-vibration, Strengthened Welding (Special for Vibration Environment)

Cooling: ✅ Original factory with metal heat sink (LSE standard)

Wide Temperature: ✅ Supports Low / High Temperature Harsh Environments

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

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

242: 0~+70°C, No Encapsulation, No Cooling → Standard Version

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

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

242LE: -40~+85°C, Encapsulation, No Cooling → Wide Temperature Encapsulation (Early Mark)

242LSE: -40~+85°C, Encapsulation, Original Factory Heat Sink → Wide Temperature Encapsulation Cooling (Mass Production Official Mark, =LE + Cooling)

242LNS: Same as LSE (Different Manufacturer Numbering, Fully Compatible)

Rule: L = Encapsulation, E/S = Wide Temperature, N/E = Cooling; 242 Full Series has no SCSI

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

242LE: Wide Temperature + Encapsulation, No Cooling (Depends on Cabinet Airflow)

242LSE: Wide Temperature + Encapsulation + Original Factory Heat Sink (More Stable in High / Enclosed Cabinet, Proliminary Enhanced Version of LE)

242LNS: Same as LSE, Only Manufacturer Naming Difference, Can Be Directly Interchangeable

VII. Typical Applications

Vehicle / Ship / Rail Transit (Wide Temperature + Vibration + Enclosed Cabinet)

Outdoor Equipment, High Temperature Workshop, No Air Conditioning Cabinet (Cooling Priority)

High Reliability Industrial Control, Vibration Equipment, Machine Tools, Robots (Wide Temperature + Cooling)

High-end Requirements without SCSI, without 4IP, but with Wide Temperature + Encapsulation + Cooling

VIII. Compatible Replacement

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

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