ZHCSDZ1E July 2015 – July 2024 TUSB4020BI
PRODUCTION DATA
The TUSB4020BI supports a serial interface for configuration register access. The device can be configured by an attached I2C EEPROM or accessed as a target by a SMBus-capable host controller. The external interface is enabled when both the SCL/SMBCLK and SDA/SMBDAT terminals are pulled up to 3.3V at the deassertion of reset. The mode, I2C controller, or SMBus target is determined by the state of SMBUSz terminal at reset.
