ICM7170IPG – HARRIS

The ICM7170IPG, manufactured by HARRIS (later Intersil), is a monolithic CMOS real-time clock (RTC) integrated circuit designed for low-power applications requiring accurate timekeeping. Fabricated using a 1996-era CMOS process, this device provides a complete time-of-day clock with calendar functions including seconds, minutes, hours, day of the week, date, month, and year, with automatic leap year correction. The device communicates via a simple parallel interface, enabling easy integration with microprocessors and microcontrollers. The ICM7170IPG operates from a single 5V DC supply. It is noted as not being compliant with the Restriction of Hazardous Substances (RoHS) directive, reflecting its design and manufacture prior to the implementation of RoHS regulations. The device is typically housed in a DIP package.
