BQ4802LYDW TI Real-Time Clock | 28-SOIC | 3V/5V, 64B RAM

Product Overview

The BQ4802LYDW from Texas Instruments is a low-power, pin-compatible real-time clock (RTC) module with a built-in crystal, 64 bytes of non-volatile static RAM, and a full century calendar. It operates from a 3V or 5V supply and is designed for direct replacement of industry-standard RTCs. The device is housed in a 28-pin SOIC package and provides timekeeping functions including seconds, minutes, hours, day, date, month, and year with leap-year compensation valid up to 2100. The BQ4802LYDW features a multiplexed byte-wide interface that supports both Intel and Motorola bus timing.
