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
