NXP Semiconductors P3T1035HUKAZ

Overview

P3T1035HUKAZ from NXP Semiconductors is a high-accuracy digital temperature sensor with I3C and I²C interfaces, operating from −40 °C to +125 °C, delivering ±0.5 °C accuracy (0 °C to +70 °C at V_CC ≥ 1.62 V), 12-bit resolution (0.0625 °C), and ultra-low 6 μA typical supply current - deployed in thermal monitoring for SSDs, notebooks, and IoT edge nodes.

For engineers reviewing the P3T1035HUKAZ datasheet, P3T1035HUKAZ pinout, P3T1035HUKAZ application, or P3T1035HUKAZ equivalent, this page delivers verified specifications, WLCSP4 package layout, I3C/I²C register-level behavior, overtemperature flagging logic, and validated alternative part comparisons - all grounded in NXP's Rev. 1.3 product data sheet.

Technical Context

The P3T1035HUKAZ integrates an on-chip bandgap temperature sensor with a 12-bit successive-approximation ADC, storing readings in a two's complement Temp register (00h) accessible via I3C SDR or Fast-mode Plus I²C. It supports three functional modes - one-shot, continuous conversion, and shutdown - controlled by M1/M0 bits in the Conf register (01h).

I²C operation includes Multiple Device Access (MDA) for simultaneous register writes/reads across up to eight devices using dedicated MDA addresses (00000000/00000001), while I3C mode enables dynamic address assignment via SETDASA CCC and supports in-band interrupts (IBI) triggered by tHIGH/tLOW threshold crossings - both features validated in Sections 7.3.5 and 7.4 of the datasheet.

FAQ

What is the guaranteed accuracy specification for P3T1035HUKAZ across its full operating temperature range?

The P3T1035HUKAZ guarantees ±0.5 °C maximum accuracy from 0 °C to +70 °C when V_CC ≥ 1.62 V. Outside this range, accuracy degrades to ±1 °C from −40 °C to +125 °C under the same supply condition. These values are explicitly defined in Section 1 and Table 27 of the P3T1035HUKAZ datasheet Rev. 1.3.

Does P3T1035HUKAZ support true I3C High Data Rate (HDR) modes, or only SDR?

The P3T1035HUKAZ implements MIPI I3C SDR (Single Data Rate) only - it does not support HDR-DDR, HDR-TSP, or HDR-TSL modes. This is confirmed in Section 7.4 ("I3C bus serial interface") of the datasheet, which states "MIPI I3C SDR only target interface" and references SETDASA/GETPID/GETBCR CCCs compliant with I3C v1.1.0 SDR definitions.

How many unique I²C addresses are available for P3T1035HUKAZ, and what is its specific address?

The P3T1035HUKAZ is the 'H' variant in the P3T1035xUK family and has a fixed 7-bit I²C target address of 1110111 (0x77). As shown in Table 2 and Table 5 of the datasheet, eight variants (A–H) provide distinct addresses from 1110000 (0x70) to 1110111 (0x77), enabling up to eight P3T1035HUKAZ units on a single I²C bus without address conflict.

Can P3T1035HUKAZ operate in shutdown mode, and what is its current draw in that state?

Yes, P3T1035HUKAZ supports shutdown mode via M1/M0 bits in the Conf register (01h), reducing supply current to <1 μA (typical). This mode disables the ADC and temperature conversion circuitry while retaining register contents and I²C/I3C interface readiness - ideal for battery-backed systems requiring periodic wake-up thermal checks.

What is the function of the FH and FL bits in the Configuration register of P3T1035HUKAZ?

The FH (flag-high) and FL (flag-low) bits in the Conf register (01h) are status flags set automatically when measured temperature exceeds tHIGH or falls below tLOW register thresholds. They persist until cleared by software write and enable interrupt-driven thermal event handling - a key enabler for I3C in-band interrupts (IBI) as described in Section 7.4.6 of the P3T1035HUKAZ datasheet.
