EM Microelectronic EM3028

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. 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.

DESCRIPTION

Thus allowing several hours of backup supply using cost effective MLCC capacitors. All addresses and data are transferred over an I2C-bus interface for communication with a host controller. It is available in a TSSOP14 plastic package or as a module combining the 32 kHz Crystal with the RTC IC in an ultrasmall, hermetically sealed C7 SMD package, factory calibrated to an initial accuracy of ± 1ppm.
