Overview
LC75056PE is a Digital Sound Processor which integrates audio signal
processor, A/D, D/A, and volume into a single chip which are the
prerequisites for car audio DSP.
Programs are downloaded from internal Flash ROM into DSP RAM.
(Caution)
On-board programming to the Flash ROM of LC75056PE is not available.
(Data is programmable only before delivery by Our company.)
