BQ4285S-SB2 TI Real-Time Clock | 24-SOIC | 5V, 64 Bytes NVSRAM

Product Overview

The BQ4285S-SB2 from Texas Instruments is a high-performance real-time clock (RTC) module with 64 bytes of nonvolatile static RAM (NVSRAM). It integrates a quartz crystal, lithium battery, and support circuitry in a compact 24-SOIC package. The device maintains accurate timekeeping and data retention for over 10 years in the absence of external power. It operates from a single 5V supply and features a multiplexed byte-wide interface for easy integration with microcontrollers and processors.
