DS90UB953-Q1: Does I2C support 16b reg address sensor

Other Parts Discussed in Thread: ALP,

Hi Team,

May I know if 953 can communicate with sensors that register address is 16bit? I'm asking because 953 registers are 8b only? If it supports 16b sensor, do I need any configuration? Thanks!

Hi Jianjun,

Thank you for your patience.

The DS90UB953-Q1 should be able to pass through I2C commands addressing the 16-bit address registers of the sensor without any issues. For more information about how to address these 16-bit registers using ALP, please refer to this E2E thread: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/797643/ds90ub954-q1-can-i-do-32-bit-address-writes-in-alp-in-python
