DS12C887 Real time clock low power DIP 18 pin IC

DS12C887 Real time clock low power DIP 18 pin IC

This is a real-time clock IC. It is widely used to provide exact times and dates in many applications such as x86 IBM PC. This IC provides time components hour, minute, and second in addition to the date or calendar components of year, month, and day. It consists of an internal lithium battery which keeps the time and date updated even when the power is off. It has a very low power consumption. This DS12CC887 IC has a total of 128 bytes of nonvolatile RAM. It uses 14 bytes of RAM for storing the values of the clock/calendar and control registers. The rest 114 bytes of RAM are for general-purpose data storage.

Features

1. Drop-in replacement for IBM AT computer clock/calendar
2. Totally nonvolatile with over 10 years of operation in the absence of power
3. Also, the Self-contained subsystem includes lithium, quartz, and support circuitry.
4. Moreover, the Daylight savings time option
