GENERAL DESCRIPTION
The PCF8584 is an integrated circuit designed in CMOS
technology which serves as an interface between most
standard parallel-bus microcontrollers/microprocessors
and the serial I
2
C-bus. The PCF8584 provides both master
and slave functions.
Communication with the I
2
C-bus is carried out on a
byte-wise basis using interrupt or polled handshake.
It controls all the I
2
C-bus specific sequences, protocol,
arbitration and timing. The PCF8584 allows parallel-bus
systems to communicate bidirectionally with the I
2
C-bus.
