DS12CR887-33+ Description

Short technical summary and product information.

The Analog Devices / Maxim Integrated DS12CR887-33+ is a Clock/Calendar Real Time Clock (RTC) IC designed for embedded systems, utility meters, and security systems. It provides essential timekeeping functions including seconds, minutes, hours, day, date, month, and year with leap-year compensation up to 2100.

 

This RTC IC operates at voltages of 2V to 3.05V and 3.3V, with a typical current draw of 2mA at 2.97V. It features a parallel interface for access and includes 114 bytes of general-purpose battery-backed NVRAM. The device supports both 12-hour and 24-hour time formats and offers features like a time-of-day alarm, programmable square-wave output, and automatic power-fail detect circuitry.

 

The DS12CR887-33+ is housed in a 24-EDIP package and supports through-hole mounting. It operates within an industrial temperature range of -40°C to 85°C. The module integrates a crystal and battery, and includes trickle-charge capability for a rechargeable battery or super capacitor, making it a robust solution for applications requiring continuous timekeeping.
