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 controller and target 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.

This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode. 1442125286808710770774 PSP 751.0 KB None None documents None 1442125286808710770774 /docs/en/user-guide/UM10204.pdf 750958 /docs/en/user-guide/UM10204.pdf UM10204 documents N N 2016-07-12 I2C-bus specification and user manual /docs/en/user-guide/UM10204.pdf /docs/en/user-guide/UM10204.pdf User Guide N 132339537837198660 2024-10-24 en Oct 1, 2021 132339537837198660 User Guide Y N I2C-bus specification and user manual 6.0 Japanese 1442125286808710770774ja PSP 751.0 KB None None documents None 1442125286808710770774 /docs/ja/user-guide/UM10204.pdf 750958 /docs/ja/user-guide/UM10204.pdf UM10204 documents N N 2016-07-12 I2C-bus specification and user manual /docs/ja/user-guide/UM10204.pdf /docs/ja/user-guide/UM10204.pdf User Guide N 132339537837198660 2024-10-24 pdf N ja Apr 28, 2014 132339537837198660 User Guide Y N I2C-bus specification and user manual カタログ Brochure 1 10 1.0 English 1442049055209726632372 PSP 278.6 KB None None documents None 1442049055209726632372 /docs/en/brochure/75015687.pdf 278634 /docs/en/brochure/75015687.pdf 75015687 documents N N 2011-09-12 1-MHz I2C-bus control on longer buses;
