Product Details
MP3 decoding has never been easier! The VS1011, a well - loved single - chip MP3 audio decoder from VLSI, comes in an easy - to - solder SOIC package. It's equipped with a high - performance, low - power DSP processor core VS DSP4, working data memory, and 5.5kBytes of program or data RAM for user applications. It also features serial control and input data interfaces, along with a high - quality oversampling variable - sample - rate stereo DAC. The VS1011 gets its input bitstream via a serial input bus. After decoding, the stream is sent to an 18 - bit oversampling, multi - bit, sigma - delta DAC and earphone driver. Control commands are transferred through the same serial bus as data. Besides basic MP3 decoding, it can play PCM and WAV files, and optionally MP1 and MP2 decoding can be enabled (check licensing). The 5.5 kB RAM is reserved for user - specific features like DSP effects. It's available in a SOIC - 28 pin package. Key features include decoding MPEG1.0&2.0 audio layer III, WAV and PCM files, supporting VBR and streaming, being robust to bit errors, having a single 12 - 13MHz or 24 - 26 MHz clock, decoding 320 kbit/s MP3 with a 12.0 MHz external clock, built - in Bass and Treble controls, extremely low - power operation, industrial temperature range, internal ground buffered, a stereo earphone driver for 30 ohm loads, separate operating voltages for analog and digital, on - off earphone transient suppression, clear sound from an internal digital sample rate converter, serial control and data interfaces, 5.5 kB on - chip RAM for user code and data, the ability to add new functions with software using VSKIT, SPI EEPROM boot for special applications, 4 general purpose IO pins, and a RoHS compliant package. Documents available are the VLSI Website and the VS1011 Datasheet.
Using the VS1011E - S MP3 Codec IC is quite straightforward. First, connect it to your system using the serial input bus for both data and control commands. Once connected, you can start playing MP3, PCM, and WAV files right away. If you want to play MP1 and MP2 files, make sure to check the licensing issues. You can adjust the sound quality with the built - in Bass and Treble controls. When it comes to power, it runs on a single 12 - 13MHz or 24 - 26 MHz clock, and it's very energy - efficient. For maintenance, keep it in an environment within the industrial temperature range. The package is RoHS compliant, so it's environmentally friendly. Be aware of the on - off earphone transient suppression feature to avoid sudden loud noises. And if you want to add new functions, you can use the VSKIT software. Just refer to the VLSI Website and the VS1011 Datasheet for more detailed information.
