CH569

Overview

CH569 and CH565 are based on RISC-V3A core, and support the IMAC subset of RISC-V instructions. The chip integrates super-speed USB3.0 host and device controller (built-in PHY), Gigabit Ethernet controller, dedicated high-speed SerDes controller (built-in PHY, can drive optical fiber directly), high-speed parallel interface (HSPI), digital video port (DVP), SD/EMMC interface controller and encryption/decryption module. The DMA with width of 128 bits can ensure high-speed transfer of large amounts of data. CH569/CH565 can be widely used in streaming media, instant storage, super-speed USB3.0 FIFO, communication extension, security monitor and other applications.
