BU9532KS2 Datasheet | LSI Computer Systems

Description BU9532KS2 is a digital signal processor LSI with built-in pre-servo amplifier developed for CD players. This built-in pre-servo amplifier is applied to the RW functions of the pact disc. bining ROHM's BU24393 - a system micro controller with this new DSP BU9532KS2 provides an extremely simplified CD system.
