The convenience timer is a CMOS timer IC which operates with low current consumption, and is suitable for the time management of the relative time.
The S-35710M A Series compares the timer value and the value written to the internal register, and outputs an interrupt signal when the values match each other.
The timer of the S-35710M A Series 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 an interrupt signal can be set freely.
Since the S-35710M A Series 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.

Caution: This product can be used in vehicle equipment and in-vehicle equipment. Before using the product for these purposes, it is imperative to contact our sales representatives.

  • 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.
