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
the parallel bus system to communicate bi-directionally with the
I
be a transmitter or receiver. Communication with the I
carried out on a byte-wise basis using interrupt or polled handshake.
The PCA9564 controls all the I
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
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.
