Introduction

The S5L8030B Audio MP3CDP SoC solution presents a rich set of features for a typical stand-alone Audio CD systems: high-quality audio processing, fully embedded CD front-end unit (RF, servo control, and CD-DSP).
The S5L8030B also includes the following components: a 16-bit MCU with 24-bit audio DSP coprocessor, 4-channel timers, I/O ports, audio PWM processor, 1-channel UARTs, SPI, and PLLs for clock generation. Especially, The S5L8030B micro-architecture makes the solution more cost effective.

The CalmADM3 is a cost effective MCU+DSP solution based on Samsung's 16-bit MCU (CalmRISC16) and 24-bit audio DSP (CalmMAC24), which is conducting system management and high quality audio processing like decoding MP3 and WMA.
