SMBUS

SMBUS(SystemManagementBus,系統(tǒng)管理總線)是1995年由Intel提出的，應(yīng)用于移動(dòng)PC和桌面PC系統(tǒng)中的低速率通訊。希望通過(guò)一條廉價(jià)并且功能強(qiáng)大的總線（由兩條線組成），來(lái)控制主板上的設(shè)備并收集相應(yīng)的信息。

  • PCA9536—4位I2C和SMBUS IO口產(chǎn)品數(shù)據(jù)手冊(cè)

    The PCA9536 is an 8-pin CMOS device that provides 4 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBUS applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.

  • PCA9534—帶中斷的低功耗8位I2C和SMBUS IO口

    The PCA9534 is a 16-pin CMOS device that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBUS applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.
