R2A20150NP expander equivalent, 8-bit i/o expander.
* Simple 2-wire (SCL and SDA) communication with a microcontroller.
* 8-bit data conversion between serial and parallel by I2C BUS.
* Corresponds to Fast mode.
The R2A20150NP/SA is a CMOS 8-bit I/O expander, which has serial to parallel and parallel to serial data converting functions.
It can communicate with a microcontroller via few wiring thanks to the adoption of the 2-wire I2C BUS. Maximum 8 ICs can be.
