DESCRIPTION

· The S-35710 Series is a wake-up timer IC designed for intermittent system operation by periodically waking up the system.

· It features a 24-bit binary-up counter and compares the timer value with the internal register value to output a wake-up signal when they match.

· Users can freely set the internal register data via a 2-wire serial interface, allowing customizable wake-up signal timing.

FEATURES

· Wake-up function: Settable from 1 second to 194 days (approximately half a year).

· Low current consumption: 0.2 μA typical (Quartz crystal: CL = 6.0 pF, VDD = 3.0 V, Ta = +25°C).

· Wide operation voltage range: 1.8 V to 5.5 V.

· 2-wire (I2C-bus) CPU interface.

· Built-in 32.768 kHz crystal oscillation circuit.

· Operation temperature range: -40°C to +85°C.

· Lead-free (Sn 100%), halogen-free.

APPLICATIONS

· IoT communications devices.

· Monitoring devices.

· Security devices.

· Battery systems.

· Energy harvesting systems.
