NXP Semiconductors P3T1035DUKAZ

Overview

P3T1035DUKAZ 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 overtemperature detection - used in thermal monitoring of SSDs, portable devices, and server DIMMs.

For engineers reviewing the P3T1035DUKAZ datasheet, P3T1035DUKAZ pinout, P3T1035DUKAZ application, or P3T1035DUKAZ equivalent, this page provides verified technical context, validated pin functions, confirmed I3C/I²C register behavior, real-world thermal accuracy boundaries, and two manufacturer-validated alternative options for multi-device thermal sensing systems.

Technical Context

The P3T1035DUKAZ implements an on-chip bandgap temperature sensor with 12-bit successive-approximation ADC, storing readings in a two-byte Temp register 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 Configuration register.

It features factory-programmed I²C static address 1110 011 (0x73), eight selectable device addresses (A–H), and MIPI I3C target capabilities including dynamic address assignment (SETDASA), GETPID/GETBCR/GETDCR CCC support, and in-band interrupt (IBI) generation triggered by tHIGH/tLOW threshold crossings.

FAQ

What is the I²C static address of the P3T1035DUKAZ?

The P3T1035DUKAZ has a factory-programmed I²C static address of 1110 011 (0x73), corresponding to topside mark "D" per Table 2 of the datasheet. This address is fixed and cannot be altered via software or external pins. The P3T1035DUKAZ uses this address for all I²C transactions unless operating in I3C dynamic addressing mode, where the static address serves only for initial SETDASA command targeting.

Does the P3T1035DUKAZ support true I3C High Data Rate (HDR) modes?

No, the P3T1035DUKAZ supports MIPI I3C SDR (Single Data Rate) only, as explicitly stated in Section 7.4. It does not implement HDR-DDR, HDR-TSP, or HDR-TSL modes. Its I3C interface is compliant with I3C v1.1.1 SDR specifications, including dynamic address assignment, CCC support (GETPID, GETBCR, SETDASA), and in-band interrupt (IBI) capability - all operating within SDR timing constraints.

How does the Multiple Device Access (MDA) feature work on the P3T1035DUKAZ?

The P3T1035DUKAZ implements MDA exclusively in I²C mode using dedicated broadcast addresses 00000000 (MDA write) and 00000001 (MDA read). When an MDA write occurs, all P3T1035DUKAZ devices on the bus with unique static addresses acknowledge and simultaneously write the same data byte to the selected register (Temp, tHIGH, or tLOW MSByte only). MDA read returns one byte per device in sequence - e.g., two devices yield two consecutive bytes - requiring the controller to issue ACK after each byte.

What is the default power-on configuration of the P3T1035DUKAZ?

At power-on reset (POR), the P3T1035DUKAZ initializes with Configuration register (Conf) value 0x02: M1/M0 = 01b (continuous conversion mode), FH/FL = 0, LC = 0, CR1/CR0 = 00b, ID = 0. The pointer register defaults to 0x00, selecting the Temp register for immediate read access without sending a pointer byte. The tHIGH and tLOW registers power up at 0x3C00 (+60 °C) and 0xF600 (−10 °C), respectively.

Can the P3T1035DUKAZ operate reliably at 1.45 V supply?

Yes, the P3T1035DUKAZ is fully specified for operation down to 1.4 V. At 1.45 V (within 1.4–1.62 V range), its accuracy degrades to ±2 °C from −20 °C to +100 °C and ±3 °C from −40 °C to +125 °C, as defined in Section 1 and Table 27. All digital functionality (I²C/I3C communication, register access, MDA, IBI) remains operational at this voltage; only the temperature accuracy specification changes - no functional failure occurs.
