BQ3285S-SB2 TI Real-Time Clock | 24-SOIC | 3V, 114 Bytes NVSRAM

Product Overview

The BQ3285S-SB2 from Texas Instruments is a high-performance real-time clock (RTC) module with 114 bytes of non-volatile static RAM (NVSRAM). It integrates a quartz crystal, a lithium coin cell, and a power-fail detection circuit 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 communicates via a parallel interface and is designed for low-power operation, making it ideal for embedded systems requiring reliable time stamping and data logging.
