R2A20150NP Datasheet (Renesas) - 8-bit I/O Expander

R2A20150NP, 8-bit I/O Expander

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, s
