STMP3410
D-MajorAudio Decoder with USB, LCD and Voice Record
DESCRIPTION
SigmaTels 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 per-
formance 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 chips
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 (Σ∆) technology achieves a DAC SNR in excess of 90 dB for high-
quality audio playback.
The STMP3410 has low power consumption to allow long battery life and includes an efficient flexible on-
chip 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.
