(eg : ps2136 & ps2231 & ps2232 ..etc) PS2251-33 controller implements with pram (program ram) architecture, which can upgrade firmware code anytime if required. this is very helpful for time-to-market & mass production solution. by using this single chip solution, it will reduce a lot of efforts which was needed from r/d to production, as well as simplifying the rma problems. with the usb plug & play function and driver-less solution with most of the operating systems, this solution provides not only easy to install, but also fast, easy to use and low cost way for user. http:///
