1. 4 SPI interfaces are USARTs operating in SPI master mode.
2. 3 SPI interfaces are USARTs operating in SPI master mode.
3. UFQFP32 has 2 GPIOs, 1 UART and 1 capacitive sensing channel less that LQFP32. However, UFQFP32 features a VDD_USB pin while
LQPF32 does not.
4. LQFP48 has three GPIOs, three ADC channels and two capacitive sensing channel less than WLCSP49.
5. TFBGA64 has one GPIO, one ADC input and one capacitive sensing channel less than LQFP64.
