I. Model Positioning (Key Point)

MVME167P-34SE: Motorola/Emerson 6U VME single-height PowerPC architecture SBC, part of the MVME167P series (PowerPC high-performance version).

34: High-end model code (PowerPC 750FX 1GHz + 512MB ECC + dual gigabit + wide temperature range)

SE: Standard Extended (standard extended, with PMC + VGA)

Positioning: PowerPC 750FX 1GHz + 512MB ECC + dual gigabit + VGA + PMC - flagship VME motherboard (1GHz main frequency, higher than 24/25SE).

II. Core Hardware Parameters (Compared with 25SE, key differences: CPU 1GHz, enhanced cooling)

1) Processor (Upgrade to 1GHz 750FX, 24/25SE is 800MHz)

CPU: PowerPC 750FX, 1000MHz (1GHz)

L1: 32KB Instructions + 32KB Data

L2: 512KB Cache (Built-in, cannot be expanded)

Architecture: 32-bit RISC, approximately 1500 MIPS, stronger floating-point performance

Performance improved by approximately 25% compared to 800MHz model

2) Memory (Same as 25SE: 512MB ECC)

DRAM: 512MB SDRAM ECC (Standard, cannot be expanded)

Flash: 16MB NOR Flash (System/Firmware)

Optional Storage: 2.5" IDE / CompactFlash (CF) card

No battery SRAM (PowerPC architecture)

3) Built-in I/O (Same as 24/25SE completely)

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

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

Parallel: 1×IEEE 1284 Bidirectional

USB: 1×USB 2.0 Host

PS/2: Keyboard / Mouse

Display: Integrated VGA, up to 1600×1200

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

Expansion: 1×PMC Slot

Timers / Watchdog: Hardware WDT + Programmable Timer

4) Electrical and Environmental (Same as 25SE in wide temperature range, enhanced cooling for 1GHz)

Power Supply: +5V, +3.3V, +12V; Typical 25W (Power consumption slightly higher for 1GHz)

Operating Temperature: -40℃ to +70℃ (Industrial wide temperature enhancement)

Storage Temperature: -55℃ to +85℃

Humidity: 5% to 95%, no condensation

Cooling: Forced air cooling, 150CFM (More airflow than 24/25SE)

5) Structure

Size: 6U VME (233.4×160mm), single height

Weight: Approximately 0.9kg (Heavier due to heat sink)

III. Core Differences of 24SE / 25SE / 34SE (Must refer to when choosing)

MVME167P-24SE: 800MHz, 256MB ECC, 0-60℃ → Standard performance / Standard temperature

MVME167P-25SE: 800MHz, 512MB ECC, -40 to +70℃ → High-end memory + Wide temperature

MVME167P-34SE: 1GHz, 512MB ECC, -40 to +70℃, enhanced cooling → Flagship frequency + High-end memory + Wide temperature

I/O, VME, PMC, VGA are exactly the same, software compatible, interchangeable (requires matching cooling and power consumption).

IV. MVME167P vs. Older MVME167 (68040)

MVME167 (e.g. 33B): 68040 33MHz, 16–64MB, single 10Mbps network, SCSI, 4 serial ports → Legacy

MVME167P-34SE: PowerPC 1GHz, 512MB ECC, dual Gigabit, VGA, USB, PMC, wide temperature → Modern flagship The two generations are completely incompatible and cannot be directly replaced.

V. Typical Applications

Industrial automation ultra-high-speed master control, real-time motion control (high number of axes / high speed), machine vision (high-definition / high-speed image processing), big data collection and analysis, embedded multitasking, VME systems with harsh environments + high real-time performance + high computing power requirements.
