EM3028-C7 Datasheet Extreme Low Power Rtc Module

Manufacturer: EM Microelectronic (Swatch Group)

Overview: DATASHEET Ɩ EM3028-C7 EXTREME LOW POWER RTC MODULE WITH I2C, 32-bit UNIX time counter, 43 bytes EEPROM, Battery Switchover and Trickle Charger.

General Description

The EM3028-C7 engineered using the in-house analog low power (ALP) technology provides unmatched true ultra-low current consumption of typically 40nA 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.

Key Features

  • I Extreme low power consumption: 40 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: Factory calibrated 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 Backup Switch and Trickle Charger function. I Provides year, month, date, weekday, hours, minutes and seconds. I Automatic leap year correction; 2000 to 2099 I 32 bit UNIX time co.
