ZHCSDZ0C July 2015 – July 2024 TUSB4020BI-Q1
PRODUCTION DATA
When the SMBus interface mode is enabled, the TUSB4020BI-Q1 supports read block and write block protocols as a target-only SMBus device.
The TUSB4020BI-Q1 target address is 1000 1xyz, where:
If the TUSB4020BI-Q1 is addressed by a host using an unsupported protocol, the device does not respond. The TUSB4020BI-Q1 waits indefinitely for configuration by the SMBus host and does not connect on the upstream port until the SMBus host indicates configuration is complete by clearing the CFG_ACTIVE bit.
For details on SMBus requirements, refer to the System Management Bus Specification.
