Description
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 connected to a bus by using 3-chip select pins, so that it is possible to handle up to 64 bits data.
Features
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 (400kHz) of I2C BUS specification.
