EM3028-C7 Datasheet | EM Microelectronic

DESCRIPTION The EM3028-C7 engineered using the in-house analog low power (ALP) technology provides unmatched true ultra-low current consumption of typically 40n A 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. All addresses and data are transferred over an I2C-bus interface for munication with a host controller. This ultra-small RTC module has been specially designed for miniature and cost sensitive high volume applications.
