Overview
CSC0101A Dual PS/2 to USB Data Converter Controller
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. The CSC0101A supports two hot-pluggable and hot-swappable PS/2 ports with either port
can accept mouse or keyboard. 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
