Introduction

The CHESEN CSC0101A is an integral micro-controller for

converting PS/2 interface signal to USB applications, which

includes 8 bits high performance micro-controller core,

combined USB1.1 low-speed interface and dual PS/2

handler module. It is ideal for the legacy system support,

enabling seamless connections of traditional PS/2 interfaces

devices of mouse and keyboard to USB.
