Analysis of Motorola VME-340B Processor PCB Card

The Motorola VME-340B is a compact processor PCB card based on the VMEbus standard architecture, positioned as a "lightweight computing core for industrial embedded systems". It is highly integrated with 68030 series CPUs, expandable memory, basic I/O interfaces, and VME bus control logic, enabling data processing and module collaboration without the need for additional core components. It is designed for scenarios such as industrial automation, testing and measurement that require "real-time and reliability" but do not have extreme computing power requirements. It is a low-cost and highly adaptable core control unit in VME bus systems.

1、 Core technical parameters and hardware architecture

1. Processor and computational performance

Core CPU: Equipped with Motorola MC68EC030 or MC68030 32-bit microprocessors (both have the same core architecture, MC68EC030 is a non floating point coprocessor version, and MC68030 supports external MC68881/MC68882 floating point coprocessors), with a typical clock frequency of 16MHz/25MHz (some versions support 33MHz), equipped with 32-bit address bus and 32-bit data bus, capable of efficiently processing multitasking real-time scheduling and medium complexity data operations (such as industrial control logic and test data statistics).

Collaborative processing extension: Reserved floating-point coprocessor interface, can be externally connected to MC68882 for high-precision computing scenarios (such as machine tool motion trajectory planning, test signal waveform analysis), improving floating-point computing performance by 5-10 times, meeting precision control requirements.

2. Memory configuration: flexible expansion, balancing cost and demand

Memory Type Basic Capacity Expansion Capability Core Role

RAM (Data Memory) 2 MB DRAM can be expanded up to 8 MB to run embedded operating systems, applications, and temporary data caches. It supports parity (some versions) to reduce the risk of data errors

ROM/Flash (program storage) 256 KB ROM (or 1 MB Flash) supports 4 MB Flash extended storage system firmware (Bootloader), solidified control programs (such as industrial equipment start stop logic), Flash version supports program flashing updates

NVRAM (non-volatile memory) 8 KB (with backup battery) up to 32 KB, power-off saves key configuration parameters (such as device address, control threshold) and real-time clock (RTC) data, providing accurate timestamps (error ≤ 1 second/day)
