I. Model Positioning (Key Point)

MVME167P-24SE is a 6U VME single-height PowerPC architecture SBC from Motorola/Emerson, belonging to the MVME167P series (PowerPC version, distinct from the 68040 MVME167).

24: Configuration Code (2× Gigabit Network + Standard I/O)

SE: Standard Extended (Standard Extended version, equipped with PMC and VGA)

Positioning: PowerPC 750FX 800MHz + 256MB ECC + Dual Gigabit + VGA + PMC - High-performance industrial real-time control VME motherboard.

It is completely incompatible with MVME167 (68040) and belongs to two different architecture platforms of two generations.

II. Core Hardware Parameters (PowerPC High-Performance Version)

1) Processor (Key Upgrade: PowerPC replaces 68040)

CPU: PowerPC 750FX, 800MHz

L1: 32KB Instructions + 32KB Data

L2: 512KB Cache (Built-in, Non-expandable)

Architecture: 32-bit RISC, Approximately 1200 MIPS, Strong Floating Point

Compared to 68040 series (33MHz), performance is 30 times worse +

2) Memory (Standard ECC, Industrial-grade Reliable)

DRAM: 256MB SDRAM ECC (Standard, Maximum 512MB)

Flash: 16MB NOR Flash (System/Firmware)

Optional Storage: 2.5" IDE Hard Drive / CompactFlash (CF) Card

No Battery SRAM (PowerPC Architecture is Cancelled, Relying on Flash/NVRAM)

3) Board-Specific I/O (24SE Core: Dual Gigabit + Multiple Serial Ports + VGA)

Ethernet: 2×10/100/1000Mbps (RJ45, Gigabit, DMA)

Serial Ports: 2×RS-232 + 1×RS-422/485 (3 Ports, Maximum 115200bps)

Parallel Port: 1×IEEE 1284 Bidirectional

USB: 1×USB 2.0 (Host)

PS/2: Keyboard / Mouse Interface

Display: Integrated VGA, Maximum 1600×1200

VME Bus: A32/D32, Master/Slave/System Controller, VMEchip2

Expansion: 1×PMC Slot (Optional I/O Module)

Timer / Watchdog: Hardware WDT + Programmable Timer

4) Electrical and Environmental (Industrial Wide Temperature)

Operating Temperature: 0℃～+60℃ (Standard)

Storage Temperature: -40℃～+85℃

Humidity: 5%～95%, No Condensation

Cooling: Forced Air Cooling, 100CFM

5) Structure

Size: 6U VME (233.4×160mm), Single Height

Weight: Approximately 0.8kg

III. Differences between MVME167P and Older MVME167 Core (Must Read)

MVME167 (e.g. 033B/33B): 68040 33MHz, 16–64MB, 10Mbps Single Network, SCSI, 4 Serial Ports → Legacy Architecture

MVME167P-24SE: PowerPC 800MHz, 256–512MB, Dual Gigabit, VGA, USB, PMC → Modern High Performance

Completely Incompatible: CPU, Memory, I/O, Firmware, Software are All Different, Cannot Be Directly Replaced.
