EMERSON VE4003S5B1电源模块
VMIVME-7750 VMEbus接口由围绕Tundra Semiconductor Corporation Universe II VMEbus界面芯片构建的PCI到VMEbus桥接器提供。Universe II在一个设计中提供了可靠的高性能64位VMEbus到PCI接口。基于Universe的VMEbus接口的功能和编程在标题为：VMIC的Tundra Universe II based VMEbus interface Product manual I 2C Support的配套手册中详细介绍。VMIVME-7750支持I2C总线，可以根据Philips Semiconductor开发的I2C总线规范2.0版作为I2C总线主控器或从控器运行。通过使用National Semiconductor Super I/O I2C总线控制器实现I2C总线上的通信。该控制器能够使用中断或轮询握手在I2 C总线上进行字节通信，并在主模式下运行时支持可编程时钟速率。
The VMIVME-7750 VMEbus interface is provided by the PCI-to-VMEbus bridge built
around the Tundra Semiconductor Corporation Universe II VMEbus interface chip.
The Universe II provides a reliable high-performance 64-bit VMEbus-to-PCI interface
in one design. The functions and programming of the Universe-based VMEbus
interface are addressed in detail in a companion manual titled: VMIC’s Tundra
Universe II Based VMEbus Interface Product Manual I
2C Support
The VMIVME-7750 supports the I2C-bus and can operate as an I2C-bus master or
slave per the I2
C-bus specification, version 2.0, developed by Philips Semiconductor.
Communication over the I2C-bus is accomplished through the use of the National
Semiconductor Super I/O I2C-bus controller. This controller is capable of
communicating on the I2
C-bus on a byte-wise basis using interrupt or polled
handshaking and supports a programmable clock rate when operating in Master
mode.
