General description

The PCA9564 is an integrated circuit designed in CMOS technology that serves as an interface between most standard parallel-bus microcontrollers/microprocessors and the serial I2C-bus and allows the parallel bus system to communicate bi-directionally with the I2C-bus. The PCA9564 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-wise basis using interrupt or polled handshake. The PCA9564 controls all the I2C-bus specific sequences, protocol, arbitration and timing with no external timing element required.

The PCA9564 is similar to the PCF8584 but operates at lower voltages and higher I2C frequencies. Other enhancements requested by design engineers have also been incorporated.

While the PCF8584 supported most parallel-bus microcontrollers/ microprocessors including the Intel 8049/8051, Motorola 6800/68000 and the Zilog Z80, the PCA9564 has been designed to be very similar to the Philips standard 80C51 microcontroller I2C hardware so the devices are not code compatible. Additionally, the PCA9564 does not support the bus monitor "Snoop" mode nor the long distance mode and is not footprint compatible with the PCF8584.

Features

  • Parallel-bus to I2C-bus protocol converter and interface
  • Both master and slave functions
  • Multi-master capability
  • Internal oscillator reduces external components
  • Operating supply voltage 2.3 V to 3.6 V
  • 5 V tolerant I/Os
  • Standard and fast mode I2C capable and compatible with SMBus
  • ESD protection exceeds 2000 V HEM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceed 100 mA.
  • Packages offered: DIP20, SO20, TSSOP20, HVQFN20

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
  • Higher frequency, lower voltage migration path for the PCF8584
  • Converts 8 bits of parallel data to serial data stream to prevent having to run a large number of traces across the entire PC board
