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.)

<Addition>
1.5V reference level circuit is a circuit that prepared 1.5V power-supply voltage needed in this LSI to be easily
generable. The power supply of 1.5V is enabled by using recommendation FET shown in Figure 5-1.

* C1 is the capacitor to prevent oscillation.
In the range of operating temperature, make sure to maintain low
ESR and the capacitance recommended value is 10F because
oscillation may occur when the capacitance value changes due to
the change of temperature.
As for power supply ON, the order of DVDD33 power supply voltage (3.3V) to FET source supply voltage (3.3V) is
recommended.
