Overview
PCA9665; PCA9665A Fm+ parallel bus to I2C-bus controller Rev.
4 — 29 September 2011 Product data sheet 1.
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.
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 2.
