C3018945_CH374U chip solution verification board

Overview

CH374 is a universal interface chip for USB bus. It supports USB-HOST host mode and USB-DEVICE/SLAVE device mode. It has a built-in 3-port HUB root hub and supports low-speed and full-speed control transmission, batch transmission, interrupt transmission and synchronization/isochronous transmission. transmission. CH374 has an 8-bit data bus, read, write, chip select control lines and interrupt output, and also provides an SPI serial communication method that saves I/O pins. Supports 5V power supply voltage and 3.3V power supply voltage.
