NXP Semiconductors P3T2030EUKAZ

Overview

P3T2030EUKAZ from NXP Semiconductors is a high-accuracy digital temperature sensor operating across –40 °C to +125 °C, featuring I3C and I²C-bus interfaces, 12-bit resolution (0.0625 °C), ±2 °C accuracy over full temperature range at V_CC ≥ 1.62 V, and integrated over/undertemperature detection. It serves as a system-level thermal monitor in space-constrained server and SSD applications.

For engineers reviewing the P3T2030EUKAZ datasheet, P3T2030EUKAZ pinout, P3T2030EUKAZ application, or P3T2030EUKAZ equivalent, this page delivers verified electrical specs, WLCSP4 package details, I3C dynamic address assignment behavior, MDA-enabled multi-device I²C reads, and validated alternative part comparisons - all grounded in NXP's Rev. 1.3 product data sheet.

Technical Context

The P3T2030EUKAZ implements an on-chip bandgap temperature sensor with 12-bit successive-approximation ADC, storing results in a two's complement Temp register (00h). It supports three functional modes-continuous conversion, one-shot, and shutdown-controlled via M1/M0 bits in the Conf register (01h).

In I²C mode, it enables Multiple Device Access (MDA) for simultaneous register writes and sequential MSByte reads across up to eight devices on one bus using dedicated MDA addresses (00000000/00000001); in I3C mode, it operates as an SDR-only target with MIPI-compliant CCC support (SETDASA, GETPID, GETDCR), BCR=0x00, and DCR=0x63 indicating a temperature sensor class.

FAQ

What is the guaranteed accuracy specification for P3T2030EUKAZ across its full operating temperature range?

The P3T2030EUKAZ guarantees ±2 °C maximum accuracy from –40 °C to +125 °C when powered 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 P3T2030EUKAZ support true I3C dynamic address assignment, and how is it implemented?

Yes, P3T2030EUKAZ supports MIPI I3C SDR dynamic address assignment via the SETDASA Common Command Code (CCC). The controller sends a SETDASA command (0x87) containing the device's static address (0x74 for P3T2030EUKAZ) and a 7-bit dynamic address. This flow is confirmed in Section 7.4.4 and Figure 8 of the P3T2030EUKAZ datasheet, and requires prior ENTDAA broadcast activation.

How does the Multiple Device Access (MDA) feature work on P3T2030EUKAZ, and what are its limitations?

MDA allows a single I²C transaction to read or write the same register (Temp, tHIGH, or tLOW MSByte only) across up to eight P3T2030EUKAZ devices simultaneously using dedicated MDA addresses (0x00 for write, 0x01 for read). As documented in Section 7.3.5, MDA is I²C-only and does not function in I3C mode; it also excludes LSByte access and requires unique static addresses per device on the bus.

What is the function of the FH and FL bits in the Configuration register of P3T2030EUKAZ?

The FH (bit D3) and FL (bit D2) bits in the Conf register (01h) are latched flags indicating overtemperature (FH = 1 when Temp > tHIGH) and undertemperature (FL = 1 when Temp < tLOW) events. They remain set until cleared by software write and trigger In-Band Interrupts (IBI) in I3C mode, enabling hardware-asserted thermal alerts without continuous polling - a key capability detailed in Sections 7.4.6 and 7.5.2.1.

What package type and dimensions does P3T2030EUKAZ use, and how is it marked?

P3T2030EUKAZ uses the WLCSP4 package (SOT1375-6): 0.4 mm pitch, 0.91 mm × 0.855 mm × 0.455 mm body size. Its topside marking is "P", corresponding to I²C static address 1110100 (0x74) and I3C provisional-ID bits[11:0] = 000011101000, as defined in Tables 2 and 7 of the NXP datasheet Rev. 1.3.
