VSMD001 - VS1000 Audio Module

VS1000 Audio Module

Introduction

VS1000 Module is a very simple uart controlled Ogg Vorbis audio player. Ogg Vorbis file format is especially usefull for applications which require high compression of audio content. The audio content can be in the embedded flash or in the removable micro-SD card. Embedded nor type flash has two options 2MB and 16MB. It is recommended for the audio content when audio is frequently read (for best reliability). Micro-SD card (not included) can provide huge audio content but since most of the SD cards use multi-level nand flash architecture today they are not as well suited for constant reading over many years as embedded nor flash. The module supports all options and the decision between micro-SD card, 2MB flash and 16MB flash is left to the customer.

Interfacing with the host has been made very simple. Six wire connection (VCC, GND, RX, TX, LOUT, ROUT) is all that is typically needed to start audio. The module supports separate pins for headphone and line out. The audio content in micro-SD card and Flash are available as mass storage when USB pins are connected to the PC.

Hardware Features

  • Plays audio from micro-SD card or internal SPI Flash (or both)
  • Uses automotive graded embedded nor flash (2MB or 16MB) for boot firmware and/or audio content
  • Controlled from UART (or IO pins)
  • Uses high-performance license-free Ogg Vorbis decoder for compressed audio
  • Can be customized, both (program) functionality and audio content
  • Firmware customization tool VSIDE is available for free
  • Update/upgrade of the internal flash can be done from micro-SD card
  • Line-out or headphone stereo analog outputs with SNR>90dB (A-weighted)
  • Supports variable bit-rates and many sample rates
  • Single power supply 3.6...5.5V, Note: IOVDD is generated from internal regulators, IO pins are not 5V tolerant!
  • SD-card and Flash memory are visible as Removable Storage when USB is connected to a host. Files can be drag and dropped from the host
  • Low-power operation
  • Industrial temperature range -30degC to +85degC
  • uses VS1000 chip

Default Firmware

Default uart controlled player firmware has four functionalities:

  • usbmass - makes SPI flash memory visible as USB Mass Storage when USB is connected to PC
  • spiplayer - plays music files from SPI FLASH
  • sdplayer - plays music (Ogg Vorbis or WAV) from SD card
  • sdmass - makes SD card visible as USB Mass Storage when USB is connected to PC and SD card inserted
  • sdupdate program - updates firmware or content of the SPI FLASH from the SD card
  • the player operation is controlled from UART, with status prints available
