DESCRIPTION

FEATURES

The ES4810 Digital Audio Processor (DAP™3) is an SOC

chip designed for Audio Boom-Box and Mini-Combo

applications. It integrates a servo controller, RF amplifier,

servo DSP, MP3 and WMA decoders, USB 2.0 Driver, 2

channels audio DAC, 2 channels of audio ADC for

Karaoke, SD/MS/MMC card reader and MP3 encoder.

The ES4810 has the largest feature set and is the most

highly integrated and cost-effective solution currently

available.

• CD Optical loader with integrated servo controller and RF

amplifier.

• Disc format supports CD-R/RW, CD.

• File system supports ISO9660, UDF, NTFS, and FAT32.

• Audio DSP decodes MP3, WMA, AAC, and OGG. Can also

encode MP3 and store into USB flash or memory cards.

• USB 2.0 FS to support USB flash drive for music playback.

• Digital audio SPDIF In and Out.

• VDAC for file browsing and management.

• 2-channel audio DAC, 2-channel ADC.

• 2-channel PWM supports class D digital amplifiers.

• SD/MMC/MS card reader interface.

The ES4810 provides auxiliary control pins for AM/FM

tuner control, LCD driver and system management. The

ES4810’s internal RISC processor can be used in place of

a microcontroller to provide all system controls and user

interface.

• Audio equalizer and bass enhancement support.

• LCD panel control and FM/AM tuner control.

• Serial UART port.

The ES4810 digital audio processor is available in a 208-

pin Plastic Quad Flat Pack (PQFP) device package.

• 1.5V power supply with 3.3V tolerant I/Os,

power consumption < 1W.

• Lead-free leads.
