El uvision2 es un entorno de desarrollo para microcontroladores de varios fabricantes como infineon, siemens, etc. Se pueden escribir los programas en ensamblador y en C, se pueden compilar y depurar y simular el comportamiento de los perifericos integrados.

Yo lo use con los T80C51 de Atmel hace unos años atras y lo recomiendo ya que es muy completo.
