The Analog Devices Inc./Maxim Integrated DS1643P-70- is a real-time clock (RTC) integrated circuit featuring an 8KB parallel interface and a 34-PowerCap™ module. This clock/calendar component provides accurate timekeeping with support for leap year calculations and includes NVSRAM for data retention. It operates over a voltage range of 4.5V to 5.5V, with a typical timekeeping current draw of 3mA at 5V, and utilizes a 3V battery for backup. The DS1643P-70- supports both HH:MM:SS (24 hr) time format and YY-MM-DD-dd date format. Its parallel interface facilitates efficient data access. This device is commonly found in industrial automation, medical equipment, and data logging applications. It is supplied in a 34-PowerCap™ Module package suitable for surface mounting.
