R2A20150NP/SA
8-bit I/O Expander for I2C BUS (Corresponds to Fast mode)
R03DS0012EJ0100 Rev.1.00
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 municate 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) munication with a microcontroller.
- 8-bit data conversion between serial and parallel by I2C BUS.
- Corresponds to Fast mode (400kHz) of I2C BUS specification.
