General description

The PCA9665 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 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 controls all the I2C-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
  • I2C-bus General Call
  • Software reset on the parallel bus

Applications

  • Add I2C-bus port to controllers/processors that do not have one
  • Add additional I2C-bus ports to controllers/processors that need multiple I2C-bus ports
  • Converts 8 bits of parallel data to serial data stream to prevent having to run a large number of traces across the entire printed-circuit board
