P3T1085UK I3C, I2C-bus, 0.5 °C accuracy, digital temperature sensor Rev. 1.2 — 10 September 2024 Product data sheet 1 General description P3T1085UK is a temperature-to-digital converter with a -40 °C to +125 °C range. It uses an on-chip band gap temperature sensor and A-to-D conversion technique with overtemperature detection. The device contains a number of data registers, including a Configuration register (Conf) to store the device settings (such as device operation mode), and a temperature register (Temp) to store the digital temp reading, which can be communicated by a controller via the 2-wire serial I3C (up to 12.5 MHz) and I2C (up to 3.4 MHz) interface.
