ES4810SAA
Digital Audio Processor
Product Brief
DESCRIPTION
The ES4810SAA Digital Audio Processor (DAP™3) is an
SOC chip designed for automotive audio applications. It
integrates a se rvo c ontroller, RF amp lifier, s ervo DSP,
MP3 a nd W MA de coders, U SB 2.0 Dr iver, 2 c hannels
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 t he most highly
integrated and cost-effective solution currently available.
The ES4810 pr ovides 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 208-
pin Low-profile Quad Flat Pack (LQFP) package with lead-
free leads. T he silicon is qual ified f or an ex tended
te mper at ur e range of –40 t o 85 °C for aut omotiv e
applications.
