100 NA Real-Time Clock/Calendar with Battery Backup

PCF8523 Active

The PCF8523 is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption. Data is transferred serially via the I²C-bus with a maximum data rate of 1000 kbit/s. Alarm and timer functions are available with the possibility to generate a wake-up signal on an interrupt pin. An offset register allows fine-tuning of the clock. The PCF8523 has a backup battery switch-over circuit, which detects power failures and automatically switches to the battery supply when a power failure occurs.

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 6 1.0 English 1442125392489718872945 PSP 369.2 KB None None documents None 1442125392489718872945 /docs/en/user-guide/UM10760.pdf 369198 /docs/en/user-guide/UM10760.pdf UM10760 documents N N 2015-10-05 User manual for the I²C-bus RTC PCF8523 demo board OM13511 /docs/en/user-guide/UM10760.pdf /docs/en/user-guide/UM10760.pdf User Guide N 132339537837198660 2023-10-17 pdf N en Oct 5, 2015 132339537837198660 User Guide Y N User manual for the I²C-bus RTC PCF8523 demo board OM13511 7 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 8 1.0 English NXP provides broad portfolio of lower power Real Time Clocks 1442048649860716713778 PSP 289.3 KB None None documents None 1442048649860716713778 /docs/en/brochure/75017076.pdf 289342 /docs/en/brochure/75017076.pdf 75017076 documents N N 2019-08-21 NXP ultra-low-power RTC/calendars PCF8523 and PCF2123 /docs/en/brochure/75017076.pdf /docs/en/brochure/75017076.pdf Brochure N 712453003803778552 2022-12-07 pdf N en Aug 21, 2019 712453003803778552 Brochure Y N NXP ultra-low-power RTC/calendars PCF8523 and PCF2123 Package Information Package Information 4 9 1.1 English Outline and soldering footprint drawings of SO8 package 1455079789802691427607 PSP 175.4 KB None None documents None 1455079789802691427607 /docs/en/package-information/SOT96-1.pdf 175406 /docs/en/package-information/SOT96-1.pdf SOT96-1 documents N N 2016-10-08 Plastic, small outline package;

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.
