ES4810SAA

PRELIMINARY ESS Technology, Inc. DESCRIPTION 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. 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. The ES4810 digital audio processor is available in a 208pin Plastic Quad Flat Pack (PQFP) device package.
