PRELIMINARY VS1000 Audio Module VS1000 Audio Module Features Description • Plays audio from microSD card or SPI Flash • Uses powerful Ogg Vorbis audio format • Firmware and content can be customized • Controlled via UART or IO pins • Very simple to use, UART is enough to send commands • High-performance CD quality analog out • Supports low bit rates and various sam- ple rates • Operates from a single supply (VCC = 3.6...6.0V) (Note: other pins are not 5Vtolerant. Do not drive other pins over DVDD!) • Line output • Headphone output • SPI FLASH for code and/or data storage • MicroSD connector for data storage • Most internal nodes are routed to pinheaders for easy access and customization Applications • Elevators • Ticket machines • Audio user’s manuals • Vending machines • Car accessories • Alarm systems • PC accessories • Speaking hi-tech toys • Development board for VS1000 chip The VS1000 Module is a small, low-cost, high performance, easy to use audio player that is controlled from the IO-pins or UART. It can be used as a “plug-in” audio board in electronic systems or as a standalone small audio player. The product is supported by design services, audio content preparation and pre-programming. It is also fully configurable by the user by using free Integrated Development Tools (VSIDE) for the VS1000 IC. The use of the module does not require any advanced information from the user. Pin headers of the PCB are compatible with DIL32 footprint 2.54 pitch 15.24 mm wide (100 mils pitch, 600 mils wide). This makes it possibe to use standard DIL32 ZIF sockets or solder it by using DIL32 footprint. The left row of the PCB has digital connections for external buttons, LEDs or other circuitry. The right row has power connections, analog connections, a serial port and USB. These can be used to interface the board with a PC and VSIDE or a host microcontroller. The VS1000 Module operates from a single power supply. The board has 16 Mbits of onboard FLASH and a microSD card connector for playing license free Ogg Vorbis audio files. The module can boot from the on-board FLASH memory.
