S-35740C01A-K8T2U

Programmable Timers And Oscillators Overview

The S-35740C01A-K8T2U is a CMOS convenience timer IC designed for automotive applications with operation up to 125°C. It features a 24-bit timer and outputs fixed-cycle interrupt signals via an INT pin, with frequency and duty ratio configurable through a 2-wire I2C interface. The device operates on a supply voltage of 1.8 V to 5.5 V and includes a built-in 32.768 kHz crystal oscillation circuit. Typical current consumption is 0.2 μA at 3.0 V with the ENBL pin high. It is AEC-Q100 qualified and housed in a TMSOP-8 package.

Programmable Timers And Oscillators Feature Summary

• Low current consumption: 0.2 μA typ. at VDD = 3.0 V, ENBL = H
• Built-in 32.768 kHz quartz crystal oscillation circuit
• 2-wire (I2C-bus) CPU interface for register configuration

Programmable Timers And Oscillators Applications

• Intermittent operation of various systems
• Regular status monitoring of various systems

Programmable Timers And Oscillators Procurement Notes

Verify that the specific ordering suffix C01 corresponds to the CMOS output form as documented in the product name list. Confirm AEC-Q100 qualification details directly with the manufacturer's sales office, as general datasheets may not contain full reliability specifications. Ensure the selected quartz crystal matches the specified load capacitance if external components are required.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-power interval timer with programmable interrupt frequencies is required for automotive environments. The CMOS output option (indicated by suffix C01) provides a standard push-pull drive capability compared to open-drain alternatives. Ensure the system design accommodates the 24-bit timer range and the specific I2C timing requirements for reliable communication.
