S-35710C01A-K8T2U

Programmable Timers And Oscillators Overview

The S-35710C01A-K8T2U is a CMOS convenience timer IC from the ABLIC S-35710A series, designed for relative time management in vehicle and industrial equipment. It features a 24-bit binary-up counter that compares internal values against a user-settable wake-up register via a 2-wire I2C interface to generate an interrupt signal. The device operates on a single power supply ranging from 1.8 V to 5.5 V with a typical quiescent current of 0.2 μA at 3.0 V. It includes a built-in 32.768 kHz crystal oscillation circuit and supports operation temperatures from −40°C to +125°C. The unit is housed in a TMSOP-8 package and is AEC-Q100 qualified.

Programmable Timers And Oscillators Feature Summary

• Configurable alarm interrupt function with settable intervals from 1 second to approximately 194 days
• Ultra-low current consumption: 0.2 μA typ. (at VDD = 3.0 V, Ta = +25°C)
• Built-in 32.768 kHz quartz crystal oscillation circuit
• 2-wire (I2C-bus) CPU interface for setting wake-up times

Programmable Timers And Oscillators Applications

• Time management of various systems during sleep periods
• Vehicle equipment and in-vehicle system timing control

Programmable Timers And Oscillators Procurement Notes

Verify component authenticity through authorized channels as this part is AEC-Q100 qualified for automotive use. Confirm the specific ordering suffix matches the required package and environmental codes. Ensure design compliance with absolute maximum ratings, particularly regarding power supply voltage limits and operating temperature ranges to prevent physical damage or malfunction.

Programmable Timers And Oscillators Selection Notes

Select the S-35710C01A-K8T2U variant specifically for applications requiring an Nch open-drain output on the INT pin without an internal pull-up resistor. This distinguishes it from the B01A version which includes pull-up resistors and offers a CMOS output. Ensure the external circuitry supports open-drain logic levels and wired-OR connections compatible with the SDA and INT pins.

Programmable Timers And Oscillators Part Context

This component belongs to the S-35710A Series of convenience timers manufactured by ABLIC Inc. The series is characterized by its low power consumption and suitability for automotive environments requiring 125°C operation. The C01A designation indicates the specific output configuration and absence of internal pull-ups, differentiating it within the broader product lineup.

Programmable Timers And Oscillators Replacement Considerations

For direct functional replacement within the same family, consider the S-35710B01A-K8T2U if an internal pull-up resistor and CMOS output are acceptable alternatives. Verify that any substitute maintains the 2-wire I2C interface compatibility and meets the required 1.8 V to 5.5 V operating voltage range.
