NXP S32K144 automotive MCU uses flash protection. S32K decryption unlocks it to recover firmware.

S32K144 Protection:
- Flash controller supports read/program protection.
- Debug (JTAG/SWD) can be locked.
- FRDM-K64F / S32K SDK blocks readback.
- UTEST and flash IFR are protected.

S32K144 Decryption Methods:
1. Voltage Glitching: glitch VDD during lock check.
2. Clock Glitching: fault flash controller.
3. Decapsulation: read silicon die directly.
4. Side-Channel: power analysis during access.

S32K144 is used in automotive body electronics, gateways, and EV control.
