General Description

The PCA9665/PCA9665A serves as an interface between most standard parallel-bus microcontrollers/microprocessors and the serial I2C-bus and allows the parallel bus system to communicate bidirectionally with the I2C-bus.

The PCA9665/PCA9665A can operate as a master or a slave and can be a transmitter or receiver.

Communication with the I2C-bus is carried out on a Byte or Buffered mode using interrupt or polled handshake.
