Part Number: PCA9536
hello,I am new in I2c protocol . I am using PCA9536 i2c expander as a slave in my project. My goal is to read the slave address( i.e.,0x41) .I was tested with arduino board it works well. But i am tested with nrf52 dk it does not works.The Vdd voltage in arduino board is 3.5 volts & nrf52 dk is 2.85volts.So can any one please confirm that is PCA9536 will work on even in vdd - 2.8 volts.
The PCA9536 can operate down to 2.3V.
Do you have schematics of the two different designs? Also, it is always useful to look at the waveforms for SDA and SCL.
