S-35710B01I-K8T2U

Programmable Timers And Oscillators Overview

The ABLIC S-35710B01I-K8T2U is a programmable wake-up timer IC featuring a built-in 32.768 kHz quartz crystal oscillation circuit and a 24-bit binary-up counter. It operates on a 1.8 V to 5.5 V supply with typical current consumption of 0.2 μA at 3.0 V. The device uses a 2-wire I²C interface to set wake-up intervals from 1 second to approximately 194 days. It provides a CMOS output interrupt signal via the INT pin, which includes an internal pull-up resistor for the RST pin. The component supports operation temperatures from −40°C to +85°C and is housed in a TMSOP-8 package.

Programmable Timers And Oscillators Procurement Notes

Verify that the specific ordering suffix K8T2U corresponds to the TMSOP-8 tape packing format. Confirm the B option indicates the CL = 9.0 pF crystal configuration. Ensure the I suffix matches the required -40°C to +85°C temperature grade for the target environment.

Programmable Timers And Oscillators Selection Notes

Select this model over the C variant if a CMOS output on the INT pin is required instead of Nch open-drain. The B suffix specifies a 9.0 pF load capacitance crystal, differing from the C suffix's 6.0 pF specification. Verify system power supply stability within the 1.8 V to 5.5 V range to ensure proper oscillation start times.

Programmable Timers And Oscillators Part Context

This part belongs to the S-35710 Series of wake-up timer ICs designed for intermittent system operation. It allows periodic waking of microcontrollers by comparing an internal 24-bit counter against a user-settable register. The series supports handshake time-out interrupt signals triggered when timer values match.
