The 96 bytes of NVRAM are handy for storing calibration constants or event logs without an external EEPROM. Built-in alarm and square-wave output let the chip wake a sleeping microcontroller or generate a periodic interrupt — useful for data-logging or scheduled sensor reads.","metaTitle":"DS1343E-3+T&R SPI RTC, 20-TSSOP, Analog Devices","metaDescription":"Analog Devices DS1343E-3+T&R SPI real-time clock/calendar in 20-TSSOP. 96B NVRAM, alarm, trickle charger.
