P3T1035xUK/P3T2030xUK

I3C, I²C-bus, 0.5 °C accuracy, digital temperature sensor

Rev. 1.1 — 10 November 2023

Product data sheet

1 General description

The P3T1035xUK/P3T2030xUK is a temperature-to-digital converter from -40 °C to +125 °C range. It uses an

on-chip band gap temperature sensor and A-to-D conversion technique with an overtemperature detection.

The device contains a number of data registers: Configuration (Conf) stores the device settings such as device

operation mode, and temperature register (Temp) stores the digital temp reading, which communicates by a

controller via the 2-wire serial I3C/I²C-bus interface.

The P3T1035xUK/P3T2030xUK can be configured for different operation conditions. It can be set in normal

mode to monitor periodically the ambient temperature, or in shutdown mode to minimize power consumption.

The temperature register always stores a 12-bit two's complement data (2 Bytes), giving a temperature

resolution of 0.0625 °C. It also allows 8-bit (MSByte) reading with temperature resolution of 1 °C.

In I²C mode, the P3T1035xUK/P3T2030xUK supports global read/write operations that allow the controller

to access multiple devices simultaneously. It does not require the controller to access each P3T1035xUK/

P3T2030xUK individually.

The P3T1035xUK offers the accuracy ±0.5 °C from 0 °C to +70 °C at V_CC≥ 1.62 V.

The P3T2030xUK offers the accuracy ±2 °C from -40 °C to +125 °C at V_CC≥ 1.62 V.

See detailed description of accuracy vs temperature and V_CCrange in Section 2 and Table 27.

The P3T1035xUK/P3T2030xUK is available in WLCSP4 package and has 8 factory-programmed device

address options.
