The K26 SOM Zynq UltraScale+ MPSoC device junction temperature (Tj) represents the die temperature read from either the PS or PL System Monitor sensors. The on-die thermal sensors are used for Tj management and many other temperature-dependent functions.

The on-die temperature sensors of the Zynq UltraScale+ MPSoC device System Monitors on the K26 SOM are placed for a high accuracy measurement of the maximum junction temperature. To maintain the performance and reliability of the K26 SOM module, your design must be in compliance with the specifications in the following table.

Table 1. K26 SOM Thermal Specifications
Parameter SOM Junction Temperature (Tj)
Maximum K26 SOM operating temperature 1 K26C SOM 85°C
K26I SOM 100°C
K26 SOM critical temperature 2 K26C SOM 90°C
K26I SOM 105°C
  1. The K26 SOM maximum operating temperature is the temperature below which the product will operate at the specified clock speeds.
  2. The K26 SOM is considered damaged if it reaches or exceeds critical temperature. Maintain or shutdown the SOM prior to reaching this temperature.
