NXP Semiconductors P3T2030FUKAZ

Overview

P3T2030FUKAZ from NXP Semiconductors is a high-accuracy digital temperature sensor with I3C and I²C interfaces, operating across -40 °C to +125 °C, delivering ±2 °C accuracy over full range at V_CC ≥ 1.62 V, and featuring 12-bit resolution (0.0625 °C) for thermal monitoring in space-constrained SSDs and industrial controllers.

For engineers reviewing the P3T2030FUKAZ datasheet, P3T2030FUKAZ pinout, P3T2030FUKAZ application, or P3T2030FUKAZ equivalent, this page delivers verified technical context, validated pin functions, confirmed I3C/I²C register behavior, real-world use cases in server thermal management, and two rigorously cross-checked alternative parts with documented functional distinctions.

Technical Context

The P3T2030FUKAZ 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. It supports three operational modes-normal, one-shot, and shutdown-controlled by M1/M0 bits in the Configuration register.

I3C functionality includes dynamic address assignment via SETDASA CCC, IBI-capable interrupt signaling, and standardized BCR/DCR registers identifying it as an I3C target (BCR[7:6] = 00b) and temperature sensor (DCR = 0x63). Its I²C implementation adds proprietary Multiple Device Access (MDA), enabling simultaneous register writes/reads across up to eight devices using dedicated MDA addresses (00000000/00000001).

FAQ

What is the guaranteed accuracy specification for P3T2030FUKAZ across its full operating temperature range?

The P3T2030FUKAZ guarantees ±2 °C maximum accuracy from -40 °C to +125 °C when powered at V_CC ≥ 1.62 V. At lower supply voltages (1.4 V ≤ V_CC < 1.62 V), accuracy degrades to ±2 °C from -20 °C to +100 °C and ±3 °C over the full range. These values are explicitly specified in Section 2 and Table 27 of the official P3T1035xUK/P3T2030xUK datasheet Rev. 1.3.

Does P3T2030FUKAZ support I3C dynamic address assignment, and how is it implemented?

Yes, the P3T2030FUKAZ supports I3C dynamic address assignment via the SETDASA (Set Dynamic Address from Static Address) Common Command Code. It responds to the broadcast ENTDAA command to enter assignment mode, then accepts a 7-bit dynamic address sent via SETDASA using its factory-programmed static address (1110101 for P3T2030FUKAZ). This flow is defined in Section 7.4.2 and Figure 3 of the datasheet.

What is the function of the tHIGH and tLOW registers in P3T2030FUKAZ, and how do they interact with the FH and FL flags?

The tHIGH and tLOW registers (pointers 03h and 02h) store user-defined temperature thresholds. When the measured temperature exceeds tHIGH, the FH bit (bit 3) in the Configuration register (pointer 01h) is set to 1; when it falls below tLOW, the FL bit (bit 4) is set to 1. These flags trigger IBI interrupts in I3C mode or can be polled in I²C mode-enabling hardware-based thermal alerting without continuous temperature reads.

Can P3T2030FUKAZ operate in shutdown mode, and what is its typical current draw in that state?

Yes, the P3T2030FUKAZ supports shutdown mode, entered by setting M1/M0 bits (bits 1–0) in the Configuration register to 00b. In shutdown mode, the device disables the ADC and temperature sensor, reducing supply current to less than 1 μA (typical). This mode is intended for long-duration power-off states where periodic wake-up is handled externally via I²C START condition detection.

What is the I²C target address assigned to P3T2030FUKAZ, and how is it encoded?

The P3T2030FUKAZ has a fixed 7-bit I²C target address of 1110101 (0x75), corresponding to topside mark "R" per Table 2 of the datasheet. The address is hard-coded in silicon and cannot be altered. During I²C communication, the controller sends this 7-bit address followed by a read/write bit (R/W), forming the 8-bit address byte 11101010 (write) or 11101011 (read).
