NXP Semiconductors P3T1035EUKAZ

Overview

P3T1035EUKAZ 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. It serves as a system-level thermal monitor in space-constrained portable and server platforms.

For engineers reviewing the P3T1035EUKAZ datasheet, P3T1035EUKAZ pinout, P3T1035EUKAZ application, or P3T1035EUKAZ equivalent, this page delivers verified technical context, real-world interface behavior (I3C SDR + I²C Fast-mode Plus), confirmed WLCSP4 package dimensions, factory-programmed I²C address 1110100 (0x74), and validated alternative options for thermal sensing in low-voltage embedded systems.

Technical Context

The P3T1035EUKAZ integrates an on-chip bandgap temperature sensor and 12-bit ADC, storing readings in a two's complement Temp register accessible via I3C or I²C. It supports three functional modes-normal (periodic conversion), one-shot, and shutdown-controlled by M1/M0 bits in the Configuration register.

It implements MIPI I3C SDR target functionality with dynamic address assignment (SETDASA), BCR/DCR registers identifying it as an I3C target (BCR[7:6] = 00) 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 factory-programmed I²C address of the P3T1035EUKAZ?

The P3T1035EUKAZ has a fixed I²C target address of 1110100 (0x74), as specified in Table 2 of the datasheet. This address is laser-trimmed during wafer test and cannot be modified. It enables direct integration into I²C systems without external address configuration components, and supports Multiple Device Access (MDA) when used alongside other P3T1035xUK variants with distinct addresses on the same bus.

Does the P3T1035EUKAZ support I3C dynamic address assignment?

Yes, the P3T1035EUKAZ 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 (0x74), the P3T1035EUKAZ accepts a new 7-bit dynamic address. Its Bus Characterization Register (BCR) confirms I3C target role (BCR[7:6] = 00), and Device Characterization Register (DCR = 0x63) identifies it as a temperature sensor.

What is the temperature accuracy specification for the P3T1035EUKAZ across its full operating range?

The P3T1035EUKAZ guarantees ±0.5 °C maximum accuracy from 0 °C to +70 °C at V_CC ≥ 1.62 V. Outside that range, accuracy degrades to ±1 °C from −40 °C to +125 °C under the same supply condition. At lower voltages (1.4 V ≤ V_CC < 1.62 V), accuracy is ±2 °C (−20 °C to +100 °C) and ±3 °C (−40 °C to +125 °C), as defined in Section 2 and Table 27 of the datasheet.

Can the P3T1035EUKAZ operate in shutdown mode, and what is its current draw?

Yes, the P3T1035EUKAZ supports shutdown mode via M1/M0 bits in the Configuration register (Conf, pointer 0x01). In shutdown mode, the device disables the ADC and temperature conversion circuitry while retaining register contents and I²C/I3C interface readiness. Its typical supply current drops to 6 μA, enabling ultra-low-power thermal supervision in always-on system states.

How does the Multiple Device Access (MDA) feature work on the P3T1035EUKAZ?

MDA allows a controller to write the same value to identical registers (Temp, tHIGH, tLOW) across multiple P3T1035EUKAZ devices on one I²C bus using a single transaction. The controller sends MDA write address 0x00 after the register pointer, and all addressed devices acknowledge and store the subsequent byte. MDA supports only MSByte access (8-bit) for these registers and is I²C-only - disabled in I3C mode.
