Pin-selectable Wake-up Timer IC S-35720 Series

Wake-up Timer IC - Intermittent operation enables significantly reduce system power consumption
Wake-up Timer IC - Intermittent operation enables significantly reduce system power consumption

The wake-up timer IC allows for intermittent system operation by periodically waking up the system.
The S-35720 Series compares the timer value and the value set to the SET0 pin and the SET1 pin, and outputs a wake-up signal (interrupt signal) when the values match each other.
The timer of the S-35720 is a 24-bit binary-up counter.
4 types of wake-up time (interrupt time) can be selected depending on the SET0 pin and the SET1 pin settings.

Parts List

  • U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
    however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
  • Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
  • These descriptions may be different from the actual product name and parameter.
    Please confirm the product name and specifications with the data sheet again.
