On-chip 96 bytes of NVRAM store configuration or calibration data without a separate EEPROM — the trickle charger maintains the backup battery above 1.3 V so the SRAM contents and clock register persist during a main supply loss. Timekeeping current draws 120 µA to 160 µA at 3.63 V to 5.5 V, which sets the battery-life budget for a coin cell in a portable or backup scenario. RoHS3 compliant (2011/65/EU + 2015/863), the part is free of the ten restricted substances including lead, mercury, and cadmium, meeting the EU directive for electronic equipment placed on the market after July 2019.","metaTitle":"DS1344E-33+ RTC Clock/Calendar SPI 20-TSSOP, Active","metaDescription":"Analog Devices DS1344E-33+ SPI RTC with alarm, NVRAM, trickle charger. 3V-5.5V supply, -40°C to 85°C, 20-TSSOP.
