JAJSF70B July 2015 – January 2022 TUSB4020BI-Q1
PRODUCTION DATA
The TUSB4020BI-Q1 supports a serial interface for configuration register access. The device may be configured by an attached I2C EEPROM or accessed as a slave by a SMBus-capable host controller. The external interface is enabled when both the SCL/SMBCLK and SDA/SMBDAT terminals are pulled up to 3.3 V at the deassertion of reset. The mode, I2C master, or SMBus slave is determined by the state of SMBUSz terminal at reset.
