PCF8584
Datasheet
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 I2C-bus. The PCF8584 provides both master and slave functions.
Communication with the I2C-bus is carried out on a byte-wise basis using interrupt or polled handshake. It controls all the I2C-bus specific sequences, protocol, arbitration and timing. The PCF8584 allows parallel-bus systems to communicate bidirectionally with the I2C-bus.
Features
- Parallel-bus to I2C-bus protocol converter and interface
- Compatible with most parallel-bus microcontrollers/microprocessors including 8049, 8051, 6800, 68000 and Z80
- Both master and slave functions
- Automatic detection and adaption to bus interface type
- Programmable interrupt vector
- Multi-master capability
- I2C-bus monitor mode
- Long-distance mode (4-wire)
- Operating supply voltage 4.5 to 5.5 V
- Operating temperature range: -40 to +85 °C.
