EPC-5A 嵌入式CPU模块

EPC-5 / EPC-5A外形设计符合VMEbus规范（6U）。它为所有三个VMEbus地址空间（A32、A24和A16）提供直接VMEbus通信。EPC-5 / EPC-5A DRAM具有从PC端和VME端进行双端口访问的功能。

EXM扩展接口在电气上类似于16位PC/AT ISA总线。视频是通过称为EXM（扩展模块）的附加卡提供的。大容量存储可以通过VME机箱内部的大容量存储模块（EXP-MS/MX）添加，也可以通过提供SCSI或ide接口的其他exm从外部添加。许多其他exm可用于提供附加外设，例如:附加串行端口（RS232或RS422）、内部调制解调器、闪存EPROM存储器、定时器/计数器、PCMCIA适配器和以太网控制器。此外，适配器模块（EXP-AM）可用于安装单个8位PC插件短卡。

EPC-5A

The EPC-5 / EPC-5A form factor has been designed to the VMEbus specification (6U). It provides direct VMEbus communication to all three VMEbus address spaces (A32, A24, & A16). The EPC-5 / EPC-5A DRAM has dual-ported access from both the PC side and the VME side.

The EXM expansion interface is electrically similar to the 16-bit PC/AT ISA bus. Video is provided through an add-in card called an EXM (Expansion module). Mass storage can be added via a Mass Storage module (EXP-MS/MX) inside the VME chassis or externally via other EXMs that provide SCSI or IDE interfaces. Many other EXMs are available to provide additional peripherals such as: additional serial ports (RS232 or RS422), internal modem, Flash EPROM memory, Timer/Counter, PCMCIA adapter and Ethernet controllers. Also, an adapter module (EXP-AM) can be used to install a single 8-bit PC add-in short card.
