update the device database in my uvision3 to include a new silicon lab. mcu

I'm going to use keil to develop my application program with mcu "silicon lab. c8051f410". the keil's website indicates that keil supports this mcu, but my uvision3's device database does not have this mcu item.
Does anybody know how can I update my uvision3's device database to include this mcu ?
Thank you very much in advance.
