PCF8584
· Parallel-bus to
· 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. 3 ORDERING INFORMATION TYPE NUMBER PCF8584P PCF8584T
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.
