Typical pinout and signals

VDD — Supply voltage GND — Ground SDA / SCL — I2C data and clock (or MOSI/MISO/SCLK for SPI variant) ALERT/INT — Open-drain interrupt output for over-temperature events TEMP_IN / SENSOR — Analog sensor input or internal diode connection RESET / EN — Device enable or hardware reset

Basic electrical characteristics & timing TSC-407: Overview, Key Specs, and Practical Applications The

I2C clock rates supported: 100 kHz (standard), 400 kHz (fast) Start-up time: ~1 ms to measurement-ready after VDD stable Conversion time: 25–100 ms depending on resolution/mode Alert threshold hysteresis: typically 2–4 °C to prevent chatter

Example application circuits

Simple MCU temperature monitor (I2C)

Connect VDD to 3.3 V, GND to ground. Pull SDA and SCL up to VDD with 4.7 kΩ resistors. Connect ALERT to MCU interrupt pin with 10 kΩ pull-up. Read temperature registers over I2C every 1 s or on ALERT asserted.
