1. General description
The PCA9665 serves as an interface between most standard parallel-bus
microcontrollers/microprocessors and the serial I
2
C-bus and allows the parallel bus
system to communicate bidirectionally with the I
2
C-bus. The PCA9665 can operate as a
master or a slave and can be a transmitter or receiver. Communication with the I
2
C-bus is
carried out on a Byte or Buffered mode using interrupt or polled handshake. The
PCA9665 controls all the I
2
C-bus specific sequences, protocol, arbitration and timing with
no external timing element required.
The PCA9665 has the same footprint as the PCA9564 with additional features:
1 MHz transmission speeds
Up to 25 mA drive capability on SCL/SDA
68-byte buffer
I
2
C-bus General Call
Software reset on the parallel bus
