NXP Semiconductors P3T2030HUKAZ

Overview

P3T2030HUKAZ 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 - deployed in SSD thermal monitoring, server DIMM thermal management, and industrial controller ambient sensing.

For engineers reviewing the P3T2030HUKAZ datasheet, P3T2030HUKAZ pinout, P3T2030HUKAZ application, or P3T2030HUKAZ equivalent, key selection considerations include its WLCSP4 package footprint, factory-programmed I²C address 1110111 (0x77), I3C provisional-ID support, MDA-enabled multi-device I²C read/write, and low-quiescent-current operation (6 μA typical) for battery-sensitive embedded systems.

Technical Context

The P3T2030HUKAZ implements an on-chip bandgap temperature sensor with 12-bit successive-approximation ADC, storing two's complement temperature data in a dedicated Temp register accessible via I3C or Fast-mode Plus I²C. It supports three functional modes - one-shot, continuous conversion, and shutdown - controlled by M1/M0 bits in the Configuration register.

Its dual-interface architecture enables I3C SDR target operation with dynamic address assignment (SETDASA), BCR/DCR compliance (DCR = 0x63 for temperature sensor), and I²C-specific features including Multiple Device Access (MDA) for simultaneous register reads/writes across up to eight devices on one bus - with MDA limited to MSByte access of Temp/tHIGH/tLOW registers.

FAQ

What is the factory-programmed I²C address for P3T2030HUKAZ?

The P3T2030HUKAZ has a fixed I²C 7-bit static address of 1110111 (0x77), corresponding to topside mark "T" per Table 2 of the datasheet. This address is laser-trimmed during wafer test and cannot be modified in-system. No external address pins or configuration registers affect this value, ensuring deterministic bus initialization without software setup overhead.

Does P3T2030HUKAZ support true I3C dynamic address assignment?

Yes, the P3T2030HUKAZ fully supports MIPI I3C SDR dynamic address assignment via the SETDASA Common Command Code (CCC). When an I3C controller issues SETDASA with the device's static address (0x77), the P3T2030HUKAZ accepts a new 7-bit dynamic address - enabling plug-and-play topology discovery and eliminating static address conflicts in multi-sensor systems.

Can P3T2030HUKAZ operate reliably at 1.45 V supply?

Yes, the P3T2030HUKAZ is specified to operate across 1.4 V to 1.98 V. At 1.45 V, accuracy degrades to ±2 °C from –20 °C to +100 °C and ±3 °C from –40 °C to +125 °C per Section 2. This makes it viable for ultra-low-voltage subsystems such as LPDDR5 memory rails, provided thermal guardbands accommodate the reduced spec.

How does Multiple Device Access (MDA) function on P3T2030HUKAZ?

MDA allows a single I²C transaction to read or write the same register (Temp, tHIGH, or tLOW) across multiple P3T2030HUKAZ devices. The controller sends MDA write address 0x00 or read address 0x01 after the pointer byte; all devices on the bus respond simultaneously. MDA is I²C-only and supports only MSByte access - LSByte reads require individual addressing.

What is the meaning of the FH and FL bits in the Configuration register of P3T2030HUKAZ?

FH (Flag High) and FL (Flag Low) are status bits in the Conf register (bit positions D3 and D4) that assert when measured temperature exceeds tHIGH or falls below tLOW register thresholds. These flags persist until cleared by writing 0 to the respective bit, enabling interrupt-driven thermal event handling without continuous polling of the Temp register.
