I. Model Positioning (Key Point)

MVME167PA-24SE:

PA = Protected/Conformal Coated (Three-Defense Coating, Reinforced Industrial Grade)

24 = Entry-level Configuration (800MHz / 256MB / 0 - 60℃)

SE = Standard Extended (PMC + VGA Standard Extension) 

The three-proof reinforced version of MVME167P-24SE (with the same performance, the same I/O, the same software, but with added moisture-proof / mold-proof / salt fog-proof coatings).

II. Core Hardware Parameters (Completely identical to P-24SE)

1) Processor

CPU: PowerPC 750FX, 800MHz

L1: 32KB instructions + 32KB data

L2: 512KB on-chip cache

Performance: Approximately 1200 MIPS, hardware floating-point

2) Memory

DRAM: 256MB SDRAM ECC (board-mounted, non-expandable)

Flash: 16MB NOR Flash (firmware / system)

Optional Storage: 2.5" IDE / CompactFlash (CF)

3) Built-in I/O (Same as the entire P series)

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

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

Parallel: 1×IEEE 1284

USB: 1×USB 2.0 Host

PS/2: Keyboard / Mouse

Display: VGA, up to 1600×1200

VME: A32/D32, master / slave / system controller

Expansion: 1×PMC slot

WDT: Hardware watchdog + programmable timer

4) Electrical and Environmental (PA = ruggedized + three protection, temperature same as P-24SE)

Power Supply: +5V/+3.3V/+12V; typical 20W

Operating Temperature: 0℃ ～ +60℃ (commercial industrial grade)

Storage Temperature: -40℃ ～ +85℃

Humidity: 5%～95% without condensation

Rugged Features (PA exclusive): Whole board conformal coating (moisture / mold / salt fog protection), vibration resistance enhancement, connector reinforcement

5) Structure

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

Weight: Approximately 0.95kg (slightly heavier than P-24SE due to coating)

III. Differences between PA and P (Key points)

MVME167P-24SE: Standard version, no three protection coating, ordinary soldering / connectors → ordinary industrial environment

MVME167PA-24SE: Rugged three protection version, whole board conformal coating, vibration / moisture / mold / salt fog resistance → harsh industrial / outdoor / marine

Electrical / performance / software / pins fully compatible, can be directly interchanged

IV. MVME167PA Series Overview (Models you have asked about)

PA-24SE: 800MHz / 256MB / 0～60℃ / three protection ruggedization → entry-level ruggedization

PA-25SE: 800MHz / 512MB / -40～+70℃ / three protection ruggedization → wide temperature ruggedization

PA-34SE: 1GHz / 512MB / -40～+70℃ / three protection ruggedization → main frequency ruggedization

PA-35SE: 1GHz / 1GB / -55～+75℃ / three protection ruggedization → top configuration ruggedization

PA-36SE: 1GHz / 1GB / -55～+85℃ / military vibration resistance + three protection → extreme ruggedization
