Version: **

Infineon provides TA and ӨJA values in the flash datasheets, but not TJ (Junction temperature).

TJ can be calculated by the following formula:

TJ = (ӨJA × Power) + TA

Power = max VCC × max current

The following parameters are available in the flash datasheets for the calculation:

  • ӨJA (Theta-JA:  ( Junction-to-Ambient thermal resistance
  • TA: Ambient temperature
  • Max VCC: Maximum core power supply voltage
  • Max current: Max current for erase/program operations
