2.6 I3C sensor interface
The FRDM-MCXN947 board includes one P3T1755DP digital temperature sensor to demonstrate the I3C
capabilities of the target MCU. This sensor device allows for 32 I3C provisional IDs, supports the full operating
voltage of the board, programmable overtemperature alerts, 12b resolution, and has an accuracy of ±0.5 °C
(maximum) from –20 °C to +85 °C.
The 7-bit I2C address of the sensor device is 0b1001000 (0x48).
Figure 11 shows the I3C sensor schematic diagram.

The sensor device connect to the I3C1 controller of the device through P1_[16:17] Port. The data line is also
connected to the GPIO (P1_11/I3C1_PUR) for the I3C Pull-Up Resistance (PUR) provision through the 1 kΩ
R53 resistor.
