BQ3285ESSTR TI Real-Time Clock | 24-SSOP | 3V, I2C, 256B SRAM

Product Overview

The BQ3285ESSTR from Texas Instruments is a low-power, serial real-time clock (RTC) with 256 bytes of battery-backed SRAM. It operates from a 3V supply and communicates via an I2C interface. The device is housed in a compact 24-pin SSOP package, making it suitable for space-constrained applications. It provides seconds, minutes, hours, day, date, month, and year information, with automatic leap-year compensation valid up to 2100. The RTC features a programmable alarm and a square-wave output with selectable frequencies.
