STA8090EXGA

General description

RTC features



47-bit counter clocked by 32.768 kHz clock



32-bit for the integer part (seconds) and 15-bit for the fractional part



The integer part and the fractional part are readable independently



The counter, once enabled, can be stopped



Integer part load register (32-bit)



Fractional part load register (15-bit)



Load bit to transfer the content of the entire load register (integer+fractional part) to the

47-bit counter. Once set by the MCU this bits is cleared by the hardware to signal to the

MCU that the RTC has been updated.
