P3T1084UK

I3C, I²C-bus, 0.4 °C accuracy, digital temperature sensor

Rev. 1.0 — 29 March 2023

Product data sheet

1 General description

P3T1084UK 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.

The I²C interface supports up to four target addresses and an alert function which becomes active when the

temperature exceeds the programmed limits.

The I3C interface supports IBI (In Band Interrupt) where P3T1084UK 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. P3T1084UK 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 complement data, giving a temperature resolution of 0.0625 °C
