   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 bootloader and running entirely in the internal SRAM maybe sometimes

   Indeed an in-package winbond flash die though.

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