I. Basic Specification

MVME162PA-344E is a 6U VME dual-high industrial single-board computer (SBC) from Motorola/Emerson. It is an enhanced version of MVME162PA-344 (E=Enhanced). The core components are the same, but it focuses on enhancing anti-interference, temperature range, and reliability, making it suitable for high-noise and wide-temperature industrial environments.

II. Core Processor and Memory

Processor: MC68040RC33A, 33 MHz, 32-bit, with built-in hardware FPU, 8KB L1 cache, MMU, and integrated Petra II ASIC.

DRAM: 16MB 32-bit, with parity check.

SRAM: 512KB with battery backup, data retention during power loss.

Flash: 1MB, with 162Bug monitoring firmware.

NVRAM/RTC: 8K×8, with battery-backed real-time clock.

III. Board-Specific Interfaces (E-Type Enhanced)

Ethernet: Dual 10Mbps, DMA, 10BASE-T/AUI, E-Type enhanced isolation and anti-static.

Serial Port: 2×EIA-232-D, 1 control console (DTE), 1 user (DCE), up to 115200bps.

IP Expansion: 4 paths of IndustryPack (IP), each path with independent DMA, supporting analog/digital/serial IP modules.

VME Bus: A32/D64, master/slave/system controller, E-Type enhanced bus anti-interference and ESD protection.

Timer/Watchdog: 6×32-bit programmable timers, hardware WDT.

Note: -344E has no SCSI; SCSI is found in -344S/-344SE.

IV. Electrical and Environmental (E-Type Critical Enhancements)

Power Supply: +5V DC, typical 3.5A.

Operating Temperature: -40°C to +85°C (standard version -344 is 0°C to +70°C).

Storage Temperature: -55°C to +125°C.

Isolation and Disturbance Resistance: E-Type channel-to-channel 500Vrms, module-to-bus 1000Vrms isolation (2 times that of -344), significantly suppressing ground loops and crosstalk.

Vibration/Impact: 0.5mm peak-to-peak (10–500Hz); 10G, 50ms half-sine wave.

V. Structure and Compatibility

Size: 6U VME (233.4×160mm), double-height.

Weight: Approximately 0.9kg.

Compatibility: Compatible with -344/-344L/-344SE pins, can be directly replaced; E-Type reinforced welding, enhanced heat dissipation.

VI. Firmware and Applications

Firmware: 162Bug, supports serial port configuration, memory read/write, reset, boot.

Applicable: Industrial automation, data acquisition, motion control, embedded industrial control, especially high-noise/wide-temperature/high-reliability scenarios.
