 Wherever you go, you are surrounded by the sound. From the moment your alarm clock wakes you up, sound follows you everywhere on the Internet radio, car stereo, traffic lights, portable stereo, mobile phone, talking ATM, elevator, TV set, baby monitor, Hi-Fi equipment, toys, and many other devices.
We at VLSI Solution are part of this development. Our high-quality audio integrated circuit products help you put audio everywhere from toys to High-end Hi-Fi equipment. - VS1005 is the new flagship audio product of VLSI Solution. It is probably the world's highest integrated system-on-silicon device for personal music players. See our MP3 player presentation. Developer Board as well as engineering samples for VS1005 are now available.
- VS23S010 is the world's largest capacity, 1 Mbit, SPI RAM. It is perfect for microcontroller memory expansion applications, like internet stream buffering. Samples are available.
- VS1063 is MP3 encoder/decoder IC. It's a pin-compatible replacement for VS1053 with many added features, ranging from a speed shifter and 5-channel equalizer to a whole new full duplex codec mode. See our internet streaming presentation.
- VS1000 is a license free audio player SoC. It is intended for content sellers such as audio books, tourist guides, announcement systems and intelligent toys.
- VS1053 is a high performance decoder and encoder chip for audio streaming applications such as internet radio. VS1053 has multi-format decoding capability and customization by using IDE. This makes it attractive for commodity mp3 player market as well.
- VS8053 is a audio processor. As license free, it is ideal for low cost audio streaming applications. Due to multiple options to boot from external media (such as eeprom) as well as protection of the custom code, it is also well suited for powerful customizable sound enhancement solutions.
- VS1003 is a high quality mp3+WMA decoder. It is ideal for small micro SD card based player applications. Additionally audio processing power of the device can be used for DSP applications such as adaptive echo cancellation of Skype speaker phone.
- VS1103 is for effect processing such as reverb, echo cancellation, PCM recording, MIDI synthesis and pitch shifting of the voice. Like VS1003 it offers very simple SD card based player applications but with less cost because VS1103 does not need mp3 decoder license.
- VS1011 is a very popular mp3 decoder. It is very simple to use as an audio interface of a master processor.
- The VS1000 Module is a small, high performance, easy to use audio player that is controlled from the IO pins, UART, SPI or USB. It can be used as a "plug-in" audio board in electronic systems or as a standalone small audio player. Unit price of the module is just 5.00 Euro in 100 pcs shipments.
- The VS1053b USB Hi-Fi Player is a multi-format "MP3 player" that uses the VS1053 as a stand-alone component along with a low-cost High Speed (480 Mbit/s) USB controller. The device can play .MP3, .OGG, .AAC, .M4A, .WMA, .WAV, .IMA and .MID files with excellent sound quality. It can either use SD/SDHC cards (over 2 GB supported) or internal FLASH memory.
- The HiFi Recorder Application demonstrates the capabilities of VS1000d and VS1053b chips for high quality stereo recording from line-in or microphone interface.
- VS1003 SD Card Mini Player application is an extremely simple SD card player. It features mp3 and WMA audio formats, small size, excellent audio quality. It is likely the simplest, smallest and lowest cost SD card player in the world.
- VS1000 Button Cell Player application is a very low power audio player. It features Ogg Vorbis decoding with very low bit rates and credit card size. The low BOM of less than 3 USD and royalty free audio compression make it attractive for disposable audio applications such as audio guide of a museum or marketing gift.
- VS1000 Audio Book application demonstrates VS1000 device capabilities in portable bible or audio book application. The system features excellent audio quality, high audio compression. The smart indexing with bookmarking is capable to handle thousands of predefined jumps and endless loops.
- VS8053/VS1053/VS1063 Developer Board features comprehensive hardware interfaces for writing and testing various audio signal processing software on VS8053/VS1053/VS1063 devices
- VS10xx Prototyping Board is a simple standalone player that uses VS1011/VS1003/VS1033/VS1053/VS1063/VS1103 devices and MMC/SD card. It has wire wrap area for adding user specific features.
- VS1000 Developer Board is an application development board for VS1000. It features all necessary hardware for writing and testing new software for VS1000.
