Programmable Wake-up Timer IC with Built-in Quartz Crystal S-35710M

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-35710M compares the timer value and the value written to the internal register, and outputs a wake-up signal (interrupt signal) when the values match each other.
The timer of the S-35710M is a 24-bit binary-up counter.
The internal register data can be set freely by users via a 2-wire serial interface. Consequently, the time before the occurrence of a wake-up signal (interrupt signal) can be set freely.
Since the S-35710M has a built-in quartz crystal, a matching assessment of the IC and the quartz crystal is unnecessary. Moreover, the number of external parts can also be reduced.

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.
