Extreme Low Power RTC with I2C
 
EM Microelectronic has introduced the EM3028 Series. It is absolutely the lowest power RTC on the market. While most MCU’s have built in RTC’s, the EM3028 is an order of magnitude lower power vs. the built in RTC (nano Amps vs. micro Amps). By bypassing the MCU RTC and adding the EM3028 externally, the savings are significant power and extend the life of the battery for a wearable, portable, or IoT platform. Accuracy is another significant advantage of their system and provides stability and precision over temperature!
 
Key Features of the EM3028 Include:
  • Extreme low power consumption: 45 nA @ 3 V
  • Wide operating voltage range: 1.2 V to 5.5 V
  • Built-in tuning Fork crystal at 32’768 Hz
  • Time accuracy: possible to calibrate to ±1 ppm @ 25°C
  • Non-volatile configuration settings with user programmable offset value
  • Configuration stored in EEPROM and mirrored in RAM I Password protection to secure configuration registers I Backup Switch and Trickle Charger function
  • Provides year, month, date, weekday, hours, minutes and seconds
  • Automatic leap year correction; 2000 to 2099 I 32 bit UNIX time counter
  • Timer, alarm and external event functions with time stamp
  • Clock output: 32.768 kHz, 8192 Hz, 1024 Hz, 64 Hz, 32Hz,1 Hz
