Our customer has a product for measuring distance. We need to identify the phase change of a 5KHz sine wave signal, which jumps every second, but the phase angle changes with the distance measured by the difference, which needs to be solved. Now it is necessary to select an MCU with ADC function. When the sampling accuracy is 10 bits, it is required to sample more than 20 points within 0.2ms, and there is also a UART. Is there a suitable model recommended? I heard that ti will recommend a new generation of M3 MCU, and can also recommend models ready for mass production.
