1. General description
2. Features
The PCA9665 serves as an interface between most standard parallel-bus
microcontrollers/microprocessors and the serial I
system to communicate bidirectionally with the I
master or a slave and can be a transmitter or receiver. Communication with the I
carried out on a Byte or Buffered mode using interrupt or polled handshake. The
PCA9665 controls all the I
no external timing element required.
The PCA9665 has the same footprint as the PCA9564 with additional features:
