BQ3285ESS TI Real-Time Clock | 24-SSOP | 512B SRAM, I2C

Product Overview

The BQ3285ESS from Texas Instruments is a low-power, real-time clock (RTC) module with 512 bytes of non-volatile SRAM and a 32.768 kHz crystal oscillator. It provides timekeeping functions including seconds, minutes, hours, day, date, month, and year with leap-year compensation. The device communicates via an I2C interface and operates over a wide voltage range of 2.7V to 5.5V. Housed in a compact 24-SSOP package, it is ideal for embedded systems requiring accurate timekeeping and data retention.
