PCA9665 Fm+ parallel bus to I2C-bus controller

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 .

PCA9665 Features

* Parallel-bus to I2C-bus protocol converter and interface

* Both master and slave functions

* Multi-master capability

* Internal oscillator trimmed to 15 % accuracy reduces external components

* 1 Mbit/s and up to 25 mA SCL/SDA IOL (Fast-mode Plus (Fm+)) capability

* I2C-bus
