I. Basic Specifications

The product is a 6U dual-height VME bus industrial single-board computer, suitable for installation on standard VME chassis rails.

The core series belongs to the MVME162PA platform. The standard version has no reinforcement and no original factory heat sink, relying on the chassis ventilation system for natural cooling.

II. Processor and Memory

Equipped with an MC68040 32-bit processor with a frequency of 33 MHz, it includes a hardware floating-point unit FPU, 8KB of first-level cache, and a memory management unit MMU.

The board is standardly equipped with 16MB DRAM memory, supporting parity check function, making the industrial data operation more stable.

It is configured with 512KB battery-backed SRAM, which can save critical configurations and running data after power failure; the board is equipped with 1MB Flash storage space, and the 162Bug system monitoring firmware is solidified.

An integrated battery-backed NVRAM real-time clock module is integrated, supporting system time preservation during power failure.

III. Board Interface Configuration

It has dual 10Mbps Ethernet interfaces, supporting DMA transmission, compatible with 10BASE-T/AUI standards, and can be used for network redundancy backup.

It is equipped with two EIA-232-D serial communication interfaces, one for the system console debugging port and the other for user-defined communication ports, with a maximum baud rate of 115200bps.

It comes with 4 IndustryPack IP expansion slots, each with an independent DMA channel, allowing for the expansion of analog, digital, serial port, and bus-type IP modules.

An integrated SCSI-2 single-ended storage interface with a dedicated DMA controller is provided, enabling the connection of SCSI hard drives, optical drives, and other storage devices.

It is compatible with the standard VME bus A32/D64 working mode and supports VME bus master mode, slave mode, and system controller functions.

The board has 6 32-bit programmable timers integrated with a hardware watchdog WDT, which can prevent system freeze and reset.

IV. Electrical Working Parameters

The standard power supply is DC + 5V, with a typical working current of 3.5A.

The working temperature range is 0℃ to +70℃, belonging to the standard industrial normal temperature version; the storage temperature range is -55℃ to +125℃.

V. Structure and Operating Conditions

The entire machine has a standard 6U VME size, weighing approximately 0.9kg.

It is made with non-reinforced ordinary industrial welding technology, suitable for indoor computer rooms, ordinary industrial control cabinets, and environments with slight vibration and standard working conditions.

VI. Software and Compatibility

Factory-preinstalled 162Bug monitoring firmware is provided, supporting serial port command-line configuration, memory read/write, system reset, and program booting.

This series can be compatible and interchangeable with MVME162PA-344L, 344E, 344SE, and 344LSE pin hardware, with only differences in temperature, reinforcement, and heat dissipation configurations.
