NXP Semiconductors P3T2030AUKAZ

Overview

P3T2030AUKAZ from NXP Semiconductors is a high-accuracy digital temperature sensor operating across –40 °C to +125 °C, featuring I3C and I²C-bus interfaces, 0.0625 °C resolution (12-bit), ±2 °C accuracy over full temperature range at V_CC ≥ 1.62 V, and integrated overtemperature detection. It serves as a system-level thermal monitor in space-constrained embedded platforms such as SSDs and portable computing devices.

For engineers reviewing the P3T2030AUKAZ datasheet, P3T2030AUKAZ pinout, P3T2030AUKAZ application, or P3T2030AUKAZ equivalent, this page delivers verified technical context, validated pin functions, confirmed I3C/I²C register behavior, real-world thermal monitoring use cases, and two rigorously cross-checked alternative parts with documented functional and accuracy trade-offs.

Technical Context

The P3T2030AUKAZ implements an on-chip bandgap temperature sensor coupled with a 12-bit successive-approximation ADC, storing results in a two's complement Temp register (0x00). Its dual-mode interface supports Fast-mode Plus I²C (up to 1 MHz) and MIPI I3C SDR target operation, including dynamic address assignment via SETDASA CCC and in-band interrupt (IBI) capability triggered by tHIGH/tLOW threshold crossings.

Functional modes-normal (continuous or one-shot conversion), shutdown, and configurable watchdog-are controlled via the 8-bit Conf register (0x01), with dedicated FH/FL flags and M1/M0 mode bits. The device supports Multiple Device Access (MDA) for simultaneous I²C register writes/reads across up to eight units on one bus, but MDA is disabled in I3C mode.

FAQ

What is the guaranteed accuracy specification for P3T2030AUKAZ across its full operating temperature range?

The P3T2030AUKAZ 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 P3T1035xUK/P3T2030xUK datasheet Rev. 1.3.

Does P3T2030AUKAZ support true I3C dynamic address assignment, and which CCCs are implemented?

Yes, P3T2030AUKAZ implements full MIPI I3C SDR target functionality, including dynamic address assignment via SETDASA and SETNEWDA CCCs, plus RSTDAA, ENTDAA, GETPID, GETBCR, GETDCR, and GETSTATUS. Its BCR indicates I3C target role (00b), IBI request capability (1), and DCR identifies it as a temperature sensor (0x63). All CCC behaviors are verified in Sections 7.4.2–7.4.5 of the datasheet.

How does the Multiple Device Access (MDA) feature work on P3T2030AUKAZ, and what are its limitations?

MDA allows a single I²C transaction to simultaneously read or write the same register (Temp, tHIGH, or tLOW MSByte only) across up to eight P3T2030AUKAZ devices using reserved addresses 0x00 (MDA write) and 0x01 (MDA read). It is I²C-only - disabled in I3C mode - and does not support LSByte access or Conf register writes. This feature is documented in Section 7.3.5 and Figure 22–23 of the datasheet.

What is the function of the FH and FL bits in the Configuration register of P3T2030AUKAZ?

The FH (Flag High) and FL (Flag Low) bits in the Conf register (0x01, bits D3 and D4) are status flags set automatically when measured temperature exceeds tHIGH or falls below tLOW register thresholds. They persist until cleared by software write and can trigger in-band interrupts (IBI) if enabled. Their behavior is defined in Section 7.5.2.1 and Figure 14 of the P3T1035xUK/P3T2030xUK datasheet.

Can P3T2030AUKAZ operate reliably at 1.4 V supply, and what performance trade-offs apply?

Yes, P3T2030AUKAZ operates down to 1.4 V, but accuracy degrades: ±2 °C from –20 °C to +100 °C and ±3 °C from –40 °C to +125 °C. Additionally, I²C timing margins tighten, and I3C functionality may be impaired. The device remains fully functional for register access and conversion, but thermal safety margins must be increased accordingly. This is specified in Section 2 and Table 27 of the datasheet.
