AS7261N − Detailed Descriptions

I²C Slave Interface

Interface, control and reading sensor data is accomplished

through an I²C compatible slave interface via a set of registers.

I²C Feature List

• Fast mode (400 kHz) and standard mode (100 kHz) support

• 7+1-bit addressing mode

• Write format: Byte

• Read format: Byte

I²C Register Set

The 7-bit I²C slave address of AS7261N is 0x49 plus one bit for

read/write. When reading from I²C registers, the 7 + 1-bit

address should be 0x93. When writing to I²C registers, the

7+1-bit address should be 0x92.

The figure below provides a summary of the AS7261N I²C

(most significant byte is situated at the lower register address).

I²C register addresses not listed should be treated as reserved

and not used.
