Some interesting CPU capabilities are listed below:

Hard real time capable CPU with predictable execution using tightly coupled memory for instruction and data.
High speed and precision PWM suitable for motor control (BLDC, Stepper, DC).
High resolution timing measure in capture mode for some pins.
Arbitrary waveform generation in any GPIO using DMA without CPU intervention.
High speed DACs suitable to generate analog signals up to 18MHz.
Tow high speed 12 bits ADC suitable to capture up to 5MSPS in any channel.
One high speed 16 bits ADC suitable to capture up to 7.5MSPSP
Internal RAM with multiple block partitions enabling multiple peripheral access at same time without contention.
External high density RAM up to 8 MB connected across 133MHz QSPI bus accessible in memory mapped mode or block device mode with on the fly encryption/decryption.
External high density FLASH up to 16 MB connected across 133MHz QSPI bus accessible in memory mapped mode or block device mode with on the fly encryption/decryption.
Multiplexed parallel memory controller for LCD and TFT access
LCD interface with 666, 565 and 888 RGB with hsync/vsync and pixel clk (max 150MHz)
Parallel capture port at 110MHz
Parallel signal generation at 50MHz

These capabilities enable multiple interesting applications:
