BQ3285S-SB2TR TI Real-Time Clock | 24-SOIC | 512B SRAM, I2C

Product Overview

The BQ3285S-SB2TR from Texas Instruments is a low-power, serial real-time clock (RTC) with 512 bytes of battery-backed SRAM. It operates over a wide voltage range and provides timekeeping, alarm, and interrupt functions. The device is housed in a compact 24-SOIC package, making it suitable for space-constrained applications.
