APPLICATIONS
Add I
2
C bus port to controllers/processors that don’t have one
Add additional I
2
C bus ports to controllers/processors that need
multiple I
2
C 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
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 I
2
C-bus and allows
the parallel bus system to communicate bi-directionally with the
I
2
C-bus. The PCA9564 can operate as a master or a slave and can
be a transmitter or receiver. Communication with the I
2
C-bus is
carried out on a byte-wise basis using interrupt or polled handshake.
The PCA9564 controls all the I
2
C-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 I C 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 I
2
C
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 foot print compatible with the
PCF8584.
