RA-4565SA (Real time Clock Module for Automotive Serial Interface)

RA-4565SA is used in vehicles to ensure normal operation at high temperatures from -40 ° C to+125 ° C, with a data retention judgment function. By using a VL bit value, the validity of the data restored after backup can be determined. 32.768kHz frequency output function, CLKOUT pin output (open drain output), can choose output frequency of 32.768kHz, 1024Hz, 32Hz, or 1Hz. Timer function, timer function can be set t values between 1/4096 seconds and 255 minutes, automatically recorded to TF bit when an event occurs,/INT output (open drain output), alarm function, can specify day, week, time, minute alarm function, automatically recorded to TF bit when an event occurs,/INT output (open drain output).
