The CH375 is fully compatible with the CH372 in USB device mode, offering all of the CH372’s features. In USB host mode, the CH375 supports full-speed USB devices and allows external microcontrollers to interface with USB devices using the USB protocol. Its firmware includes a specialized protocol for Mass-Storage devices, enabling the microcontroller to read and write data to USB storage devices (such as USB hard drives, flash drives, and U-disks) using sectors as the basic data unit.
Equipped with an 8-bit data bus and control lines for reading, writing, chip selection, and interrupt output, the CH375 ensures easy integration with the system bus of microcontrollers, DSPs, MCUs, or MPUs. In USB host mode, it also supports serial communication through serial input, serial output, and interrupt outputs, allowing seamless connection to monolithic/DSP/MCU/MPU systems.
