PCF8575
Information as of 2000-08-24
PCF8575; Remote 16-bit I/O expander for IC-bus
The PCF8575 is a silicon CMOS circuit. It provides general purpose remote I/O expansion for most microcontroller families via the two-line
bidirectional bus (IC-bus).
The device consists of a 16-bit quasi-bidirectional port and an IC-bus interface. The PCF8575 has a low current consumption and includes
latched outputs with high current drive capability for directly driving LEDs. It also possesses an interrupt line (INT) which can be connected
to the interrupt logic of the microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there
is incoming data on its ports without having to communicate via the IC-bus. This means that the PCF8575 is an IC-bus slave
transmitter/receiver.
Every data transmission from the PCF8575 must consist of an even number of bytes, the first byte will be referred to as P07 to P00 and the
second byte as P17 to P10. The third will be referred to as P07 to P00 and so on.
