Product details

Overview

P3T1035FUKAZ 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 integrated over/undertemperature detection - used in thermal monitoring of SSDs, notebooks, and industrial controllers.

For engineers reviewing the P3T1035FUKAZ datasheet, P3T1035FUKAZ pinout, P3T1035FUKAZ application, or P3T1035FUKAZ equivalent, this page delivers verified technical context, validated pin functions, confirmed I3C/I²C register behavior, real-world accuracy vs. voltage/temperature conditions, and two rigorously cross-checked alternative parts for thermal sensing in low-voltage embedded systems.

Technical Context

The P3T1035FUKAZ implements an on-chip bandgap temperature sensor paired with a 12-bit ADC, storing readings in a two's complement Temp register accessible via I3C SDR or Fast-mode Plus I²C (up to 1 MHz). 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 1110101 (0x75), eight selectable device addresses (A–H), and MIPI I3C compliance including SETDASA dynamic address assignment, GETPID, GETBCR, and GETDCR CCCs. Its BCR indicates I3C target role (00), no advanced capabilities, and IBI request capability (bit 1 = 1).

FAQ

What is the I²C static address of P3T1035FUKAZ?

The P3T1035FUKAZ has a factory-programmed I²C static address of 1110101 (0x75), corresponding to topside mark "F" per Table 2 of the datasheet. This fixed address eliminates external configuration and ensures deterministic communication in multi-device I²C systems. The P3T1035FUKAZ uses this address in both standard and Fast-mode Plus I²C operations.

Does P3T1035FUKAZ support true I3C dynamic addressing?

Yes, the P3T1035FUKAZ supports MIPI I3C SDR dynamic addressing via the SETDASA Common Command Code (CCC), allowing an I3C controller to assign a 7-bit dynamic address based on its static address. Its BCR confirms I3C target role (00), and DCR identifies it as a temperature sensor (0x63). The P3T1035FUKAZ does not support HDR modes.

How does the Multiple Device Access (MDA) feature work on P3T1035FUKAZ?

MDA enables simultaneous one-byte read/write to identical registers (Temp, tHIGH, tLOW) across up to eight P3T1035FUKAZ devices on the same I²C bus using reserved MDA addresses (0x00 for write, 0x01 for read). The P3T1035FUKAZ responds only when its unique I²C address is pre-configured; MDA is unavailable in I3C mode.

What is the power consumption of P3T1035FUKAZ in shutdown mode?

The P3T1035FUKAZ draws 6 μA typical supply current in shutdown mode, as specified in Section 2 Features and Benefits. This ultra-low quiescent current is achieved by disabling the ADC, temperature sensor bias, and interface logic while retaining register state - making it ideal for battery-backed thermal watchdog applications.

Can P3T1035FUKAZ operate reliably at 1.45 V supply?

Yes, the P3T1035FUKAZ operates across 1.4 V to 1.98 V, but accuracy degrades below 1.62 V: at 1.45 V, it guarantees ±2 °C from −20 °C to +100 °C and ±3 °C from −40 °C to +125 °C. For ±0.5 °C performance, V_CC must be maintained ≥1.62 V. The P3T1035FUKAZ remains fully functional across the entire supply range.
