I. Model Positioning (Key Point)

MVME167P-35SE: Motorola/Emerson 6U VME single-height PowerPC architecture SBC, the top-of-the-line wide-temperature model in the MVME167P series.

35: The code for the flagship top-of-the-line model (PowerPC 750FX 1GHz + 1GB ECC + dual gigabit + enhanced wide-temperature + extremely strong cooling)

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

Positioning: PowerPC 750FX 1GHz + 1GB ECC + dual gigabit + VGA + PMC - fully top-of-the-line / ultra-wide-temperature / extremely high reliability VME motherboard (1GB memory, double of 34SE).

II. Core Hardware Parameters (Compared with 34SE, key upgrades: 1GB ECC, ultra-wide temperature range, enhanced cooling)

1) Processor (Same as 34SE: 1GHz 750FX, 24/25SE is 800MHz)

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

L1: 32KB Instructions + 32KB Data; L2: 512KB Cache

32-bit RISC, approximately 1500 MIPS, strong hardware floating-point

Performance is improved by about 25% compared to the 800MHz model

2) Memory (Maximum upgrade for 35SE: 1GB ECC, 34SE is 512MB ECC)

DRAM: 1GB SDRAM ECC (Standard, non-expandable, maximum for the entire series)

Flash: 16MB NOR Flash (System/Firmware)

Optional storage: 2.5" IDE / CompactFlash (CF)

No battery SRAM (PowerPC architecture)

3) Built-in I/O (Completely the same as 24/25/34SE)

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 (35SE ultra-wide temperature range: -55°C to +75°C, 34SE is -40°C to +70°C)

Power supply: +5V, +3.3V, +12V; typical 28W (maximum power consumption for 1GHz + 1GB)

Operating temperature: -55°C to +75°C (industrial ultra-wide temperature, strongest for the entire series)

Storage temperature: -60°C to +85°C

Humidity: 5% to 95%, no condensation

Cooling: Forced air cooling, 200CFM (maximum cooling surface, highest air volume)

5) Structure

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

Weight: Approximately 1.0kg (heaviest with cooling surface)

III. Ultimate Comparison of 24SE / 25SE / 34SE / 35SE (Must refer to the selection)

MVME167P-24SE: 800MHz, 256MB ECC, 0-60°C → Entry-level entry

MVME167P-25SE: 800MHz, 512MB ECC, -40°C to +70°C → Wide temperature high-end configuration

MVME167P-34SE: 1GHz, 512MB ECC, -40°C to +70°C, enhanced cooling → Flagship main frequency

MVME167P-35SE: 1GHz, 1GB ECC, -55°C to +75°C, super cooling → Top configuration + ultra-wide temperature (entire series ceiling)

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

IV. Differences between MVME167P and older MVME167 (68040)

MVME167 (such as 33B): 68040 33MHz, 16–64MB, single 10Mbps network, SCSI, 4 serial ports → legacy

MVME167P-35SE: PowerPC 1GHz, 1GB ECC, dual gigabit, VGA, USB, PMC, ultra-wide temperature range → Modern top-of-the-line configuration

Two generations are completely incompatible and cannot be directly replaced.

V. Typical Applications

Industrial automation extreme performance controller, ultra-high-speed motion control (multi-axis / high precision), machine vision (4K / high-speed image processing), massive data acquisition and real-time analysis, embedded multitasking, extremely cold / high temperature / strong interference / extremely high reliability, requires 1GB ECC + dual gigabit + ultra-wide temperature range VME system (aerospace, military, nuclear industry, polar equipment).
