BQ4285LS TI Real-Time Clock | 24-SOIC | 5V, 128x8 RAM, 24-Pin SOIC

Product Overview

The BQ4285LS from Texas Instruments is a low-power, 5V real-time clock (RTC) module with 128 bytes of non-volatile static RAM, integrated in a compact 24-SOIC package. It provides timekeeping functions including seconds, minutes, hours, day, date, month, and year with leap-year compensation through the year 2099. The device operates from a single 5V supply and features a multiplexed byte-wide interface for communication with microcontrollers. Its built-in power-sense circuit detects power failures and automatically switches to a backup battery, ensuring reliable timekeeping during main power loss.
