Motorola VME-340B 处理器 PCB 卡解析

一、核心技术参数与硬件架构

1. 处理器与运算性能

• 核心 CPU：搭载 Motorola MC68EC030 或 MC68030 32 位微处理器（二者核心架构一致，MC68EC030 为无浮点协处理器版本，MC68030 支持外接 MC68881/MC68882 浮点协处理器），主频典型值 16MHz/25MHz（部分版本支持 33MHz），具备 32 位地址总线与 32 位数据总线，可高效处理多任务实时调度与中等复杂度数据运算（如工业控制逻辑、测试数据统计）。
• 协处理扩展：预留浮点协处理器接口，需高精度计算场景（如机床运动轨迹规划、测试信号波形分析）可外接 MC68882，浮点运算性能提升 5-10 倍，满足精密控制需求。

2. 内存配置：灵活扩展，兼顾成本与需求

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)
