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.
The CSC0101A is a USB 1.1 low-speed compliant device
that interfaces to PS/2, it support the Human Interface
Device (HID) class specification. The CSC0101A handles
the merging of the PS/2 data and sends the data to the host
system via the USB port.
