Teach your devices to speak with VS1000 audio module
VS10000 audio module is a simple solution how to add audio output to your device, at a low cost. Thanks to a high quality stereo sound with SNR>90dB it can be used even in applications demanding for a sound quality. License-free OggVorbis decoder enables to freely change audio content without any other fees.
A decision how to add an audio interface to a device, is usually a question
of complexity, development costs and direct costs for production. From more ways
how to reach it, VS1000 audio module offers a smart way to add this
functionality at a low cost. It can be used as a “plug-in” audio board in
electronic systems or as a standalone small audio player.
VS1000 audio module plays audio from internal SPI Flash or from micro-SD
card (or both). Micro-SD card can serve for firmware update, copying audio
content into internal Flash or as a high capacity memory for audio content. Up
to 20 minutes play time from internal 16 Mbit Flash, can be extended to several
days by using micro-SD card. A real CD audio quality can be reached, with SNR>90
dB, crosstalk 75 dB and a flat frequency response from 20 to 20 000 Hz. Outputs
are line and for headphones. Line outputs have the first order RC low-pass
filter that removes some of the DA converter quantization noise at high
frequencies.
Control of module is very simple, via USB, UART or IO pins. VS1000 comes from
production with a default firmware, ready to use. High performance license-free
Ogg Vorbis decoder supports variable bit rates and various sample rates. Single
power supply 3.4 to 6V and low power consumption make the VS1000 suitable also
for portable devices. Typical power consumption in play mode is 120 mW. The
module also contains a VCC voltage monitor, which causes interrupt when it is
activated. Using voltage monitor, it is possible to shut down the system by the
firmware before voltage level causes functionality error.
Pin headers of the PCB are compatible with DIL32 footprint enabling to use
standard DIL32 ZIF sockets or solder the module by using DIL32 footprint.
VS1000 audio module datasheet contains also application examples, incl.
standalone button-controlled player.
