7.10.3.1 I²C interface

The AS7058 I²C slave uses an I²C address of 0x55 (7-bit format; R/W bit has to be added) -

AAh (8-bit format for writing) and ABh (8-bit format for reading) respectively. It expects external

pull-up resistors on the SDA_MOSI and SCL pins. Furthermore, it is mandatory to connect and

external pull up resistors to CSXN pin for I²C interface selection. The interface supports the

following features:

•

Fast mode plus (1 MHz)

•

Fast Mode (400 kHz)

•

Standard Mode (100 kHz)

•

7+1-bit addressing mode

•

Write formats

– Single-Byte-Write

– Burst-Write

•

Read formats

– Current-Address-Read

– Random-Read

– Sequential-Read.

•

IEEE standard requirements regarding filtering and timing are implemented.
