EM3028 - EXTREME LOW POWER RTC

General Description

The EM3028 engineered using the in-house analog low power ( ALP ) technology provides unmatched true ultra-low current consumption of typically 45nA while running on a standard 32’768 Hz tuning fork crystal.

Thus allowing several hours of backup supply using cost effective MLCC capacitors.

Key Features

  • I Extreme low power consumption: 45 nA @ 3 V. I Wide operating voltage range: 1.2 V to 5.5 V. I Built-in tuning Fork crystal at 32’768 Hz I Time accuracy: possible to calibrate to ±1 ppm @ 25°C I Non-volatile configuration settings with user programmable offset value. I Configuration stored in EEPROM and mirrored in RAM I Password protection to secure configuration registers I Backup Switch and Trickle Charger function. I Provides year, month, date, weekday, hours, minutes and seconds. I Automat.

DATASHEET Ɩ EM3028 EXTREME LOW POWER RTC WITH I2C, 32-bit UNIX time counter, 43 bytes EEPROM, Battery Switchover and Trickle Charger DESCRIPTION The EM3028 engineered using the in-house analog low power ( ALP ) technology provides unmatched true ultra-low current consumption of typically 45nA while running on a standard 32’768 Hz tuning fork crystal. Thus allowing several hours of backup supply using cost effective MLCC capacitors. It provides full RTC function with programmable counters, alarm, selectable interrupt and clock output functions and also a 32-bit UNIX Time counter. The internal EEPROM memory hosts all configuration settings and allows for additional 43 bytes of user memory.
