Analog Devices Inc./Maxim Integrated DS1644P-120 is a Real Time Clock (RTC) IC featuring a 32KB Parallel interface and a 34-PowerCap™ Module package. This clock/calendar component is designed for applications requiring accurate timekeeping and date tracking, incorporating leap year compensation and non-volatile SRAM. The DS1644P-120 operates within a voltage range of 4.5V to 5.5V, with a timekeeping current draw of 4mA at 4.5V. Its parallel interface allows for direct access to time and calendar data, formatted as YY-MM-DD-dd for date and HH:MM:SS (24 hr) for time. This component is suitable for surface mount applications and operates within a temperature range of 0°C to 70°C. Industries benefiting from this component include industrial automation, telecommunications, and embedded systems where reliable time-of-day and date information is critical.
