P3T1085UK Datasheet | NXP Semiconductors

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 municated by a controller via the 2-wire serial I3C (up to 12.5 MHz) and I2C (up to 3.4 MHz) interface. The I2C interface supports up to four target addresses and an alert function which bees active when the temperature exceeds the programmed limits. The I3C interface supports IBI (In Band Interrupt) where P3T1085UK emits its address into the arbitrated address header on the I3C bus to notify the controller of an interrupt. It does not require an additional interrupt pin. P3T1085UK can be configured for different operation conditions. It can be set in normal mode to periodically monitor the ambient temperature, or in shut-down mode to minimize power consumption. The temperature register always stores a 12 bit two's plement data, giving a temperature resolution of 0.0625 °C.
