NXP | PCF8584T/2,518

NXP is a leading semiconductor company founded by Philips more than 50 years ago. NXP creates semiconductors, system solutions and software that deliver better sensory experiences in TVs, set-top boxes, identification applications, mobile phones, cars and a wide range of other electronic devices.

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.

The PCF8584 is compatible with most parallel-bus microcontrollers/microprocessors including 8049, 8051, 6800, 68000 and Z80. It features both master and slave functions as well as automatic detection and adaptation to bus interface type. Other features include programmable interrupt vector; multi-master capability; I2C-bus monitor mode and long-distance mode (4-wire).

The PCF8584TD-T is an I²C Bus Controller has a voltage - supply of 4.5 V ~ 5.5 V, Current - Supply 1.5mA, is 20-pin, in a SOIC (7.5mm Width). The PCF8584TD-T comes in tape and reel format.
