ICM7170AIBG – HARRIS

The ICM7170AIBG, manufactured by HARRIS (now Intersil, acquired by Renesas), is a monolithic CMOS real-time clock (RTC) circuit. This device provides a time-of-day clock/calendar function with programmable alarm and interrupt capabilities. Specifically, the ICM7170AIBG generates seconds, minutes, hours, day of the week, date, month, and year information. The device communicates via a multiplexed BCD (Binary-Coded Decimal) interface, requiring external components for conversion to other formats. The “A” designation likely indicates a specific revision or performance grade. The “IBG” suffix denotes the package type, which is a PDIP (Plastic Dual In-line Package). Note that the provided information explicitly states the part is NOT RoHS compliant, indicating the presence of lead or other restricted substances in its construction, potentially limiting its use in certain applications and regions.
