The PCF8563 is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption. A programmable clock output, interrupt output, and voltage-low detector are also provided. All addresses and data are transferred serially via a two-line bidirectional I²C-bus. Maximum bus speed is 400 kbit/s. The register address is incremented automatically after each written or read data byte.

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 pdf N en Oct 1, 2021 132339537837198660 User Guide Y N I2C-bus specification and user manual 5 2.1 English 1442125649798715943478 PSP 983.6 KB None None documents None 1442125649798715943478 /docs/en/user-guide/UM10301.pdf 983634 /docs/en/user-guide/UM10301.pdf UM10301 documents N N 2016-07-11 User Manual for NXP Real Time Clocks PCF85x3, PCF85x63, PCA8565, PCF2123, and PCA21125 /docs/en/user-guide/UM10301.pdf /docs/en/user-guide/UM10301.pdf User Guide N 132339537837198660 2025-01-10 pdf N en Jul 24, 2015 132339537837198660 User Guide Y N User Manual for NXP Real Time Clocks PCF85x3, PCF85x63, PCA8565, PCF2123, and PCA21125 Brochure Brochure 1 6 1.0 English 1442124656944726362331 PSP 1.1 MB None None documents None 1442124656944726362331 /docs/en/brochure/75016543.pdf 1091243 /docs/en/brochure/75016543.pdf 75016543 documents N N 2016-10-08 Create smarter, more efficient white goods;

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.
