Buenas he mirado y remirado el foro pero no sale nada de este chip
Bueno hace tiempo me compre un doongle para desbloquear un programa de musica llamado cubase 4(el caso es que el programa vale 400 euros y el doongle este me costo 20...como era de esperar me engañaaron xD)
el tema es que me acorde que lo tenia y lo he abierto ,para mi sorpresa tiene un AT90SC464SC-USB,asi que bueno supongo que habra que hacerle un port,o que directamente n valdra. Aun asi pongo el datasheet del microcontrolador
