CA9665A - Fm+ parallel bus to I2C-bus controller

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.

Key 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 General Call capability.
  • Software reset on parallel bus.
  • 68-byte data buffer.
  • Operating supply voltage: 2.3 V to 3.6 V.
  • 5 V tolerant I/Os.
  • Standard-mode and Fast-mode I2C-bus.

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.
