NXP Semiconductors P3T2030DUKAZ

Overview

P3T2030DUKAZ from NXP Semiconductors is a high-accuracy digital temperature sensor with I3C and I²C 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 server and SSD applications.

For engineers reviewing the P3T2030DUKAZ datasheet, P3T2030DUKAZ pinout, P3T2030DUKAZ application, or P3T2030DUKAZ equivalent, this page delivers verified functional specifications, validated WLCSP4 package mapping, confirmed I3C/I²C dual-interface behavior, and real-world thermal sensing use cases - all grounded in NXP's official Rev. 1.3 product data sheet.

Technical Context

The P3T2030DUKAZ integrates an on-chip bandgap temperature sensor with 12-bit ADC conversion and stores readings in a two-byte Temp register accessible via I3C or Fast-mode Plus I²C. It supports three operational modes-continuous, one-shot, and shutdown-controlled by M1/M0 bits in the Configuration register.

It implements MIPI I3C SDR-only target functionality with dynamic address assignment (SETDASA), BCR/DCR registers identifying it as an I3C target (BCR[7:6] = 00b) and temperature sensor (DCR = 0x63), plus I²C-specific features including Multiple Device Access (MDA) for simultaneous register writes across up to eight devices on one bus.

FAQ

What is the guaranteed accuracy specification for P3T2030DUKAZ across its full operating temperature range?

The P3T2030DUKAZ guarantees ±2 °C maximum accuracy from −40 °C to +125 °C when operated at 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 over the full range. These values are specified in Table 27 of the official NXP P3T1035xUK/P3T2030xUK datasheet Rev. 1.3.

Does P3T2030DUKAZ support true I3C dynamic addressing, and how is it implemented?

Yes, P3T2030DUKAZ supports full MIPI I3C SDR dynamic addressing via the SETDASA Common Command Code (CCC). The controller assigns a 7-bit dynamic address using the device's static I²C address (1110011 for P3T2030DUKAZ), as defined in Section 7.4.4 and Figure 8 of the datasheet. It also supports ENTDAA and RSTDAA CCCs for coordinated address management.

What is the I²C target address assigned to P3T2030DUKAZ, and how is it encoded?

P3T2030DUKAZ uses I²C 7-bit target address 1110011 (0x73), as confirmed in Table 2 and Table 5 of the NXP datasheet. This address is factory-programmed and corresponds to topside mark "N". The device does not support address modification in-system - address selection is done at order time via part number suffix (A–H for P3T1035xUK; K–T for P3T2030xUK).

Can P3T2030DUKAZ operate in shutdown mode, and what is its typical current draw in that state?

Yes, P3T2030DUKAZ supports shutdown mode via M1/M0 bits in the Configuration register (Conf, pointer 01h). In shutdown mode, it draws 6 μA typical supply current, as stated in Section 2 Features and Benefits. This mode disables ADC conversion and serial interface activity while retaining register contents and allowing wake-up via I²C start condition or I3C bus activity.

How does the Multiple Device Access (MDA) feature work on P3T2030DUKAZ, and what are its limitations?

MDA enables simultaneous register access across multiple P3T2030DUKAZ devices on one I²C bus using special addresses 0x00 (MDA write) and 0x01 (MDA read). It supports only one-byte (MSByte) reads/writes to Temp, tHIGH, and tLOW registers - LSByte access is disabled during MDA. MDA is I²C-only and unavailable in I3C mode, as documented in Section 7.3.5.
