R2A20150NP - 8-bit I/O Expander

Renesas

Datasheet Details

The R2A20150NP/SA is a CMOS 8-bit I/O expander, which has serial to parallel and parallel to serial data converting functions.

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.
Possible to set input and output each bit separately.
By using three chip select pins (CS0,CS1,CS2), R2A20150 can connect with the same BUS line to maximum 8 pieces.
Very small package line-up QFN-16 and TSSOP-16.
