Cortex-R82 may be the only microcontroller-class ARM core with MMU, but there are few chance for a random dev to develop on them.

The same as P4 rev 3.x, which is still undocumented. Assembler source and esp-nn/esp-dsp are your friend. Some people have also tried some stuff. And HP core 0 is scalar-only now.

In terms of security features, it lacks on-the-fly external memory (flash and PSRAM) encryption and decryption as ESP32 and some newer STM32s did. Decrypting by custom OTP bootload…

Indeed an in-package winbond flash die though.

Octal PSRAM usually cannot fallback to quad mode like some octal flash did.
