DS1501WEN+ Description

Short technical summary and product information.

The DS1501WEN+ is a Y2K-compliant real-time clock (RTC) and calendar IC from Analog Devices / Maxim Integrated. It provides essential features for timekeeping applications, including an RTC alarm, a watchdog timer, and power-on reset capabilities.

 

This device offers 256 bytes of battery-backed Non-Volatile Static Random-Access Memory (NV SRAM) for data storage. The RTC registers store century, year, month, date, day, hours, minutes, and seconds in 24-hour Binary-Coded Decimal (BCD) format, with automatic leap-year compensation valid up to the year 2100. It supports a voltage range of 2.5V to 3.7V and operates at a typical current of 4mA at 3V.

 

The DS1501WEN+ is available in a 28-TSOP package, suitable for surface mounting. Its features make it suitable for applications such as remote systems, battery-backed systems, telecom switches, office equipment, and consumer electronics.
