S-35710 is a Wakeup timer IC (1s to194days) made by ABLIC. This posting will provide the OSS-ECAL(Open Source Software for Electronic Components Abstraction Layer) for S-35710.
MCU interface : I2C, GPIO
CAUTION:Please be sure to refer to the latest version of the Datasheet prior to actual design.
S-35710
General description
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.
Feature
- Built-in 32.768 kHz quartz crystal
- Wake-up function (Alarm interrupt function): Settable on the second time scale from 1 second to 194 days
(Approximately half a year) - Low current consumption: 0.25 μA typ. (VDD = 3.0 V, Ta = +25°C)
- Wide range of operation voltage: 1.8 V to 5.5 V
- 2-wire (I2C-bus) CPU interface
- Operation temperature range: Ta = −40°C to +85°C
- Lead-free (Sn 100%), halogen-free
Application
- IoT communications device
- Monitoring device
- Security device
- Battery system
- Energy harvesting system
