Abstract
Using USB interface control chip with I2C Bus to implement a USB interface when the speed is not required very high. It will reduce the using of microcontroller′s pins and simplify the circuit. This paper introduces the Philips PDIUSBD11, a USB interface control chip with I2C Bus, and its peripheral circuit and the design of firmware.
