APPLICATIONS

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

the parallel bus system to communicate bi-directionally with the

carried out on a byte-wise basis using interrupt or polled handshake.

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

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.
