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 and benefits

  • 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.

Applications

  • Hand-held radio equipment in common emitter class-AB operation for 900 MHz Time Division Multiple Axis (TDMA) communication systems.

NXP Semiconductors' products are specifically designed and manufactured to be used within the electrical, thermal, mechanical and other parameters set forth in NXP Semiconductors' data sheets. Quality and reliability data provided by NXP Semiconductors, such as MTBF, MSL and FIT, is intended to be a non-binding estimate of product performance based upon diffusion process, history only. It does not imply that any performance levels reflected in such data can be met if the product is operated outside the conditions expressly stated in the latest published data sheet for a device or in your application.

The RoHS data provided hereunder is preliminary and non binding for NXP Semiconductors. NXP Semiconductors does not accept any liability related to this data.

NXP Semiconductors products are not designed, authorized or warranted to be suitable for use in medical, military, aircraft, space or life support equipment, nor in applications where failure or malfunction of an NXP Semiconductors product can reasonably be expected to result in personal injury, death or severe property or environmental damage nor for any other use that is not explicitly agreed between the parties. NXP Semiconductors accepts no liability for inclusion and/or use of NXP Semiconductors products in such equipment or applications and therefore such inclusion and/or use is at the customer's own risk.

Any use of NXP Semiconductors' products beyond the scope defined in the current NXP Semiconductors' data sheet voids all warranty responsibility of NXP Semiconductors with respect to such devices, and also voids all responsibility of NXP Semiconductors with respect to any applications assistance, product design, software performance or services of any kind that were or may have been performed in connection with the sale of any such devices.

Further, resale of NXP Semiconductors' products or services with statements different from or beyond the parameters stated by NXP Semiconductors for that product in official NXP Semiconductors data sheets, or without the warnings or instructions provided by NXP Semiconductors, voids all express and any implied warranties for the associated NXP Semiconductors product or service, and is an unfair and deceptive business practice.
