EMERSON VE4003S5B1電源模塊
VMIVME-7750 VMEbus接口由圍繞Tundra Semiconductor Corporation Universe II VMEbus界面芯片構建的PCI到VMEbus橋接器提供。Universe II在一個設計中提供了可靠的高性能64位VMEbus到PCI接口?；赨niverse的VMEbus接口的功能和編程在標題為：VMIC的Tundra Universe II based VMEbus interface Product manual I 2C Support的配套手冊中詳細介紹。VMIVME-7750支持I2C總線，可以根據Philips Semiconductor開發(fā)的I2C總線規(guī)范2.0版作為I2C總線主控器或從控器運行。通過使用National Semiconductor Super I/O I2C總線控制器實現(xiàn)I2C總線上的通信。該控制器能夠使用中斷或輪詢握手在I2 C總線上進行字節(jié)通信，并在主模式下運行時支持可編程時鐘速率。
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.
