10 I²C interface
The N50P111 supports the 2-wire high-speed I²C protocol in device mode, according to the NXP specification UM10204.
The host MCU (master) has to initiate the data transfers. The 7-bit device address of the N50P111 depends on the state at the pin ADDR.
ADDR = 0 → Slave address =‘1000 000’ (40h)
ADDR = 1 → Slave address =‘1000 001’ (41h)
For other I²C addresses, please contact austriamicrosystems.
Supported modes (slave mode):
The SDA signal is bidirectional and is used to read and write the serial data. The SCL signal is the clock generated by the host MCU, to
synchronize the SDA data in read and write mode. The maximum I²C clock frequency is 3.4MHz, data are triggered on the rising edge of SCL.
