BQ4852YMC-85 TI Real-Time Clock | 36-DIP Module | 5V, 128Kb NVSRAM

Product Overview

The BQ4852YMC-85 from Texas Instruments is a highly integrated real-time clock (RTC) module with 128Kb of nonvolatile static RAM (NVSRAM) in a compact 36-pin DIP module. It combines a low-power RTC with a full-function calendar, alarm, and 128Kb of battery-backed SRAM, ensuring data retention for over 10 years. The device operates from a 5V supply and features a built-in lithium battery for backup. It is ideal for applications requiring accurate timekeeping and reliable data storage in harsh environments.
