Analog Devices Inc./Maxim Integrated DS1644-120- is a Real Time Clock (RTC) module with integrated 32KB NVSRAM. This clock/calendar component features a parallel interface for data access and operates within a voltage range of 4.5V to 5.5V, drawing a maximum timekeeping current of 4mA at 5V. The device supports both YY-MM-DD-dd date format and HH:MM:SS (24 hr) time format. Key features include leap year calculation and data retention via its NVSRAM. The DS1644-120- is housed in a 28-EDIP package with a 0.600" (15.24mm) module width, suitable for through-hole mounting. This component finds application in industrial automation, medical devices, and consumer electronics where accurate timekeeping and non-volatile data storage are critical.
