Shipping overseas is convenient since the embedded microprocessor is packed in QFN. In terms of uPs and uCs as well as peripheral ICs, this is a MICROCONTROLLER. In total, there are 24 terminations. When the voltage supply is 2.1V, the cpu microprocessor should be powered on and run. In terms of architecture, it is a 8-Bit system. You can find information about the functions of 24 pins in the datasheets. It can supply a maximum current of 2.75V. 50MHz is the microprocessor's clock frequency. Programs on the CPU transfer data through 18 I/Os.
