Flexible, efficient on-chip DC-DC converter More than 35 hours of operation on a single AA battery (Alkaline 2850mAh or better) Designed to operate from many different battery configurations, including 1xAA, 1xAAA, 2xAA, 2xAAA, LiIon (2xAA, 2xAAA and LiIon configurations require 144-pin package) USB download interface LED/LCD Driver Actual size Host Processor (Optional) 90 94 98 102 FM Tuner 106 Battery LED/LCD Screen USB SDRAM Microphone Voice Record Flash Memory Headphones Buttons/Switches Hard Drive CD Pickup For designs as small as 14.5 cm2 www..com 5-3410-P1-5.0-0802 www..com STMP3410 D-MajorTM Audio Decoder with USB, LCD and Voice Record DESCRIPTION SigmaTel's STMP3410 is a second generation single-chip highly-integrated digital music system solution for devices such as digital audio players, PDAs, and cell phones. It includes an audio decoder with a high performance DSP, ADPCM record capabilities and a USB interface for downloading music and uploading voice recordings. The chip also includes a mixer, DAC, ADC and provides interfaces to CD-DSPs, flash memory, LED/LCDs, button & switch inputs, headphones, FM radio input & controls and a microphone. The chip's highly programmable architecture supports MP3, WMA, and other digital audio standards. WMA digital rights management and other security schemes are also supported. The end-user can download music and also update firmware through a USB interface. For devices like PDAs and cell phones, STMP3410 can act as a slave chip to a host chip/processor. The DAC includes a headphone driver to directly drive low impedance headphones. The ADC includes inputs for both microphone and analog audio in to support voice recording & FM radio integration features. SigmaTel's proprietary Sigma-Delta () technology achieves a DAC SNR in excess of 90 dB for highquality audio playback. The STMP3410 has low power consumption to allow long battery life and includes an efficient flexible onchip DC-DC converter that allows many different battery configurations, including 1xAA, 1xAAA, 2xAA, 2xAAA and LiIon. In addition, the single-chip design and low pin count enables very small digital audio devices to be designed. 90 94 98 102 10 6 FM Radio USB Bus Microphone Mic in FM in Line in CD Control CD Control Interface Interface CDROM I2S CD I2S CD Synchronization Synchronization Interface USB USB Interface Interrupt Control, Timers, Bit Interrupt Control, Timers, Bit Manipulation Unit, RTC, Trace Manipulation Unit, RTC, Trace Debug Unit, Reed-Solomon Debug Unit, Reed-Solomon Memory Bus Peripheral Bus Boost DAC STMP3410 Headphone Amplifier Headphone Amplifier LED/LCD Buttons/ Switches MMC/SD Card I2C Peripherals SmartMedia CompactFlash NOR Flash NAND Flash Hard Drive SDRAM General Purpose Input/Output General Purpose Input/Output 6 SPI Interface SPI Interface DSP DSP I2C Interface I2C Interface ADC ADC DAC DAC Headphones Flash/IDE EMC Interface On-Chip ROM On-Chip ROM 8K x 24bits 8K x 24bits On-Chip RAM On-Chip RAM 96K x 24bits 96K x 24bits DCDC DCDC Converter Converter Low Low Resolution Resolution ADC ADC PLL PLL XTAL xtal SDRAM SDRAM Interface Interface Battery Crystal Figure 1.
