5.5 Thermal Attributes
5.5.1 Description
The tables in the following sections describe the thermal characteristics of the device. MCXEP172M160FB0 All information provided in this document is subject to legal disclaimers. © 2026 NXP B.V. All rights reserved.
5.5.2 Thermal characteristics
- Junction temperature of the device does not solely depend on package thermal resistance but is also a function of chip power dissipation, PCB attributes, environmental conditions (ambient temperature & air flow) and cumulative effects of other heat generating ICs on the PCB.
- The appropriate thermal design must be carried out on package so that it can safely dissipate the necessary amount of power needed for it to function properly without exceeding the maximum junction temperature. This may involve adding a cooling solution on the package, creating thermal enhancements on the PCB and improving environmental conditions.
- The customer is encouraged to use the package model to perform design and risk assessment through simulations. Package models in FloTHERM or Icepak formats can be obtained under NDA from the sales team. Thermal Ratings
- The table below is the package thermal ratings for LQFP and HDQFP package variants. These numbers are derived through simulations based on standardized tests as described in the footnotes.
- Thermal resistance data in this report is solely for a thermal performance comparison of one package to another in a standardized specified environment. It is not meant to predict the performance of a package in an application-specific environment :

Table 13. Recommended Decoupling Capacitors...continued [1] These capacitors must be placed as close as possible to the corresponding supply and ground pins. [2] All capacitors must be low ESR ceramic capacitors (for example, X7R). The minimum recommendation is after considering component aging and tolerance. [3] Optionally, 1 nF capacitors can be added in parallel to the decoupling capacitors. [4] These capacitors must be placed close to the source. [5] For devices where the VDD_HV_B domain is present, if the VDD_HV_B supply is different supply from VDD_HV_A, a dedicated bulk capacitor is needed. [6] It is also possible to use higher capacitance values (for example, 10 μF) in place of the 4.7 μF capacitor.

Table 23. Cyclic wake-up current example [1] The supply current is obtained through the measurements of the current during the corresponding operating mode. [2] The duration is defined by the application (how much time will the device spend in the according operating mode). [3] The ratio of duration is obtained by dividing the duration of the corresponding operating mode by the total duration of the application. [4] The current according to ratio is obtained by multiplying the supply current and the ratio of duration related to the proper operating mode. [5] The average current is calculated by the addition of each device operating mode’s current according to ratio.
