S-35710B01A-K8T2U

Programmable Timers And Oscillators Overview

The S-35710B01A-K8T2U is a CMOS convenience timer IC designed for automotive applications with operation up to +125°C. It features a 24-bit binary-up counter and an integrated 32.768 kHz crystal oscillation circuit. The device communicates via a 2-wire I²C-bus interface, allowing users to set interrupt times from 1 second to approximately 194 days. Key electrical parameters include a supply voltage range of 1.8 V to 5.5 V and typical current consumption of 0.2 μA at 3.0 V. It is housed in a TMSOP-8 package and includes built-in pull-up resistors on the reset pin.

Programmable Timers And Oscillators Applications

• Time management of systems during sleep periods

Programmable Timers And Oscillators Procurement Notes

Verify that the specific ordering suffix B01 corresponds to the required internal configuration, specifically the inclusion of pull-up resistors on the RST pin and CMOS output form on the INT pin. Confirm that the CL = 9.0 pF option matches the external quartz crystal specifications used in the target design to ensure accurate timing performance.

Programmable Timers And Oscillators Selection Notes

Select this model over the C01 variant if the application requires a CMOS output on the INT pin rather than Nch open-drain, or if the design necessitates built-in pull-up resistors on the RST pin. Ensure the external quartz crystal load capacitance aligns with the 9.0 pF specification to maintain frequency accuracy within the ±25 ppm tolerance.
