BQ3285LDSS TI Real-Time Clock | 24-SSOP | 3V, 512B SRAM

Product Overview

The BQ3285LDSS from Texas Instruments is a low-power, real-time clock (RTC) module with integrated 512 bytes of battery-backed SRAM and a 32.768 kHz crystal oscillator. Housed in a compact 24-pin SSOP package, it provides accurate timekeeping, alarm functions, and non-volatile memory storage. The device operates over a wide voltage range (2.7V to 5.5V) and features a programmable square-wave output, making it suitable for a variety of embedded systems requiring precise time and date information.
