The NXP LPC553x series are general-purpose microcontrollers based on the ARM Cortex-M33 processor.

On-Chip Memory Regions

THe LPC553x series devices have an internal flash of up to 256 KiB. The PFR region is used as the persistent storage for secure boot and the SoC specific parameters.

ECC flash

The flash seems to be ECC protected. Read fails for sectors with invalid ECC (e.g. erased sectors). In order to prevent errors when reading empty sectors, the DLL do neither perform a blank check nor a compare of the flash content before programming.
