Product Details

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.


  • 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).
