32-bit High-Performance USB and Ethernet MCU - CH563


CH563 is a CPU with 32-bit reduced instruction sets. The system clock frequency is 100MHz by default, and can be up to 130MHz. The CH563 integrates high-speed USB interface and 10/100M network interface that support DMA (built-in PHY). CH563 can be widely used in various embedded applications, with features of highly integrated peripherals and high performance.
