Fm+ parallel bus to I2C-bus controller

The PCA9665/PCA9665A serves as an interface between many 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 leader or a follower 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. The PCA9665/PCA9665A

controls all the I²C-bus specific sequences, protocol, arbitration and timing with no external timing element

required.

The PCA9665 and PCA9665A have 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

* I²C-bus General Call

* Software reset on the parallel bus
