NXP Semiconductors P3T2030GUKAZ

Overview

P3T2030GUKAZ from NXP Semiconductors is a digital temperature sensor with I3C and I2C-bus interfaces, operating from −40 °C to +125 °C, delivering ±2 °C accuracy across the full range at V_CC ≥ 1.62 V, and featuring 12-bit resolution (0.0625 °C) for thermal monitoring in space-constrained embedded systems.

For engineers reviewing the P3T2030GUKAZ datasheet, P3T2030GUKAZ pinout, P3T2030GUKAZ application, or P3T2030GUKAZ equivalent, this page delivers verified specifications, WLCSP4 package details, I3C dynamic address assignment support, overtemperature detection capability, and validated alternative part options for thermal sensing in SSDs, servers, and industrial controllers.

Technical Context

The P3T2030GUKAZ integrates an on-chip bandgap temperature sensor with 12-bit ADC conversion, storing readings in a two's complement Temp register accessible via I3C SDR or Fast-mode Plus I2C. It supports three functional modes-continuous conversion, one-shot, and shutdown-controlled by M1/M0 bits in the Configuration register.

It implements MIPI I3C target functionality including GETPID, GETBCR, GETDCR, SETDASA, and RSTDAA CCCs, with BCR indicating I3C target role and DCR identifying it as a temperature sensor (0x63). Its I2C interface supports Multiple Device Access (MDA) for simultaneous register writes/reads across up to eight devices on the same bus.

FAQ

What is the guaranteed accuracy specification for P3T2030GUKAZ across its full operating temperature range?

The P3T2030GUKAZ guarantees ±2 °C maximum accuracy from −40 °C to +125 °C when supplied with V_CC ≥ 1.62 V. At lower supply voltages (1.4 V ≤ V_CC < 1.62 V), accuracy degrades to ±2 °C from −20 °C to +100 °C and ±3 °C across the full range. These values are explicitly specified in Section 2 and Table 27 of the official P3T2030GUKAZ datasheet.

Does P3T2030GUKAZ support both I2C and I3C protocols simultaneously on the same pins?

Yes, the P3T2030GUKAZ uses shared SDA and SCL pins for both I2C and I3C communication. It auto-detects protocol based on bus activity: I2C transactions use static 7-bit addresses (1110 110 for P3T2030GUKAZ), while I3C operations rely on dynamic addressing initiated via SETDASA CCC. No hardware reconfiguration is required to switch between protocols.

What is the function of the tLOW and tHIGH registers in P3T2030GUKAZ?

The tLOW and tHIGH registers (pointers 02h and 03h) store user-defined temperature thresholds in two's complement 12-bit format. When measured temperature crosses these limits, the FL or FH flag bit in the Configuration register (pointer 01h) is asserted - enabling interrupt-driven thermal event handling without continuous polling of the Temp register in the P3T2030GUKAZ.

Is P3T2030GUKAZ pin-compatible with other variants in the P3T1035xUK/P3T2030xUK family?

Yes, all P3T1035xUK and P3T2030xUK variants share identical WLCSP4 package (SOT1375-6), pinout, and footprint. The P3T2030GUKAZ differs only in factory-programmed I2C address (1110 110) and accuracy grade (±2 °C full-range), not in mechanical or electrical pin mapping - enabling drop-in replacement within the same family for design reuse.

How does the Multiple Device Access (MDA) feature work in P3T2030GUKAZ?

MDA allows a single I2C transaction to simultaneously read the MSByte of the Temp, tHIGH, or tLOW register from up to eight P3T2030GUKAZ devices on the same bus. It uses dedicated MDA write (00000000) and read (00000001) addresses - eliminating sequential polling and reducing firmware latency in multi-sensor thermal systems using the P3T2030GUKAZ.
