Motorola VME162PA-252SE VMEbus PCB 板槽（背板 / 插槽模块）

一、产品概述

二、核心技术参数

1. 总线兼容性与传输能力

• 总线标准：严格遵循 ANSI/IEEE 1014-1987 VMEbus 规范（MVME162 系列适配的经典 VME 标准），确保与所有 MVME162 系列板卡及符合 VME 标准的第三方模块兼容；
• 数据总线宽度：支持 16 位 / 32 位动态切换，适配不同模块的传输需求（如 16 位 I/O 模块用 16 位传输，32 位 CPU 模块用 32 位高速传输），最大总线传输速率匹配 VME 标准（最高 40 MB/s，取决于模块性能）；
• 地址空间：支持 VMEbus 全地址范围，包括 A16（16 位地址，64KB 空间，用于板内寄存器访问）、A24（24 位地址，16MB 空间，用于模块间数据交互）、A32（32 位地址，4GB 空间，用于大容量内存或外设访问），满足不同规模系统的地址分配需求。

2. 插槽配置与物理设计

• 插槽数量：典型配置为 4-8 个标准 VME 插槽（具体数量视系统设计而定，部分定制版本支持 12 个插槽），每个插槽均符合 VME 3U/6U 板卡尺寸规范（MVME162 系列多为 6U 板卡，插槽需匹配 6U 板卡的引脚定义）；
• 插槽引脚定义：严格遵循 VMEbus 引脚标准，每个插槽包含：
  • 数据总线引脚（D0-D31，32 位）、地址总线引脚（A0-A31，32 位）；
  • 控制信号引脚（如总线请求、总线允许、中断请求、复位信号）；
  • 电源引脚（+5V、±12V，部分支持 +3.3V 适配现代模块）；
  • 地引脚（信号地、电源地，实现电气隔离与抗干扰）；
• 物理结构：采用多层 PCB 板设计（典型 4-6 层），增强信号屏蔽与抗干扰能力；插槽采用镀金引脚（耐磨性强、接触电阻低），支持板卡反复插拔（插拔寿命≥1000 次）；背板边缘设计有安装孔，可固定在标准 VME 机箱内，适配工业环境的振动与冲击场景。

Motorola VME162PA-252SE VMEbus PCB board slot (backplane/slot module)

1、 Product Overview

Motorola VME162PA-252SE is a VMEbus architecture PCB board slot (i.e. VME backplane/slot module) designed specifically for the MVME162 series embedded control systems. Its core positioning is the "physical and electrical connection hub of the VME bus system". It achieves physical fixation and electrical interconnection of various VME boards such as CPU modules (such as MVME162PA-242LE), I/O modules (such as MVME2431), and communication modules (such as MVME204-2) through standardized VME slot interfaces, while ensuring the integrity, timing stability, and anti-interference ability of bus signals. It is the "basic skeleton" for building the MVME162 series modular system, directly determining the scalability, reliability, and data transmission efficiency of the entire system.

2、 Core technical parameters

1. Bus compatibility and transmission capability

Bus standard: Strictly following the ANSI/IEEE 1014-1987 VMEbus specification (the classic VME standard adapted to the MVME162 series), ensuring compatibility with all MVME162 series cards and third-party modules that comply with the VME standard;

Data bus width: supports 16 bit/32-bit dynamic switching, adapts to the transmission requirements of different modules (such as 16 bit transmission for 16 bit I/O modules and 32-bit high-speed transmission for 32-bit CPU modules), and the maximum bus transmission rate matches the VME standard (up to 40 MB/s, depending on module performance);

Address Space: Supports the full address range of VMEbus, including A16 (16 bit address, 64KB space for on-board register access), A24 (24 bit address, 16MB space for data exchange between modules), A32 (32-bit address, 4GB space for large capacity memory or peripheral access), meeting the address allocation requirements of systems of different sizes.

2. Slot configuration and physical design

Number of slots: The typical configuration is 4-8 standard VME slots (the specific number depends on the system design, some customized versions support 12 slots), and each slot complies with the VME 3U/6U card size specification (MVME162 series mostly uses 6U cards, and the slots need to match the pin definition of the 6U card);

Slot Pin Definition: Strictly following the VMEbus pin standard, each slot includes:

Data bus pins (D0-D31, 32-bit), address bus pins (A0-A31, 32-bit);

Control signal pins (such as bus request, bus allow, interrupt request, reset signal);
