PCF2131TFY Description

Short technical summary and product information.

The PCF2131TFY from NXP Semiconductors is a Real Time Clock (RTC) module designed for accurate timekeeping applications. It supports both I2C and SPI communication interfaces, offering flexibility in system integration. The device operates across a wide voltage supply range of 1.2V to 5.5V, making it suitable for various power configurations. Its operating temperature range is -40°C to 85°C (TA), ensuring reliable performance in diverse environmental conditions.

 

Key features of the PCF2131TFY include alarm functions, leap year calculation, integrated SRAM for data storage, and a watchdog timer for system monitoring. The clock supports both 12-hour and 24-hour time formats, along with a YY-MM-DD-dd date format. It is supplied in a compact 16-HLSON package with a surface mount, wettable flank mounting type, and is available in a 16-LFDFN Exposed Pad package.

 

This Real Time Clock is ideal for embedded systems requiring precise timekeeping, such as data loggers, industrial control systems, and portable electronic devices. The low timekeeping current consumption, ranging from 770nA to 2.135µA, makes it suitable for battery-powered applications where power efficiency is critical.
