I. Basic Specification

MVME162PA-344S is a 6U VME dual-high industrial single-board computer (SBC) from Motorola/Emerson. It is an enhanced version of MVME162PA-344 (S=SCSI), with the core components remaining the same as the standard version. It particularly retains the SCSI-2 interface and is suitable for industrial scenarios that require local large-capacity storage.

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 real-time clock.

III. Board-Specific Interfaces (Critical S-Type: with SCSI)

Ethernet: Dual 10Mbps, DMA, 10BASE-T/AUI, standard isolation.

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

SCSI-2 Single-ended: Dedicated DMA, up to 20MB/s, can connect hard drives / optical drives / tape drives, up to 7 devices (ID0-6).

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

VME Bus: A32/D64, master / slave / system controller, standard anti-interference.

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

IV. Electrical and Environmental (Same as Standard Version -344)

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

Operating Temperature: 0℃～+70℃ (non-wide temperature).

Storage Temperature: -55℃～+125℃.

Isolation Immunity: Standard level, channel-to-channel 250Vrms, module-to-bus 500Vrms.

V. Structure and Compatibility

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

Weight: Approximately 0.9kg.

Compatibility: Compatible with -344/-344L/-344SE pins; -344S has SCSI, -344E has no SCSI.

VI. Firmware and Applications

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

Applicable: Industrial automation, data acquisition, motion control, mainly used in systems requiring onboard SCSI storage.
