The SNC7648S is a multi-function voice engine, which is based on 16-bit fixed-point DSP architecture. This chip embedded 40K or 48K words hi-performance internal program RAM (boot from external flash, only one time after IC reset) and 12K or 4K words Data RAM. 40K or 48K words internal program RAM is used to implement software synthesizer in order to provide various high speed image, voice compression ,Tone Detection technology or many different fancy algorithm for users, such as 1.5kbps~32kbps voice compression, 8-CH wave-table melody, voice changer algorithm etc…. Furthermore, the SNC7648S also built-in many interfaces for connecting with external devices, such as SPI, I2S, Uart, LCM, etc…, these interfaces can create more advanced application at different areas in the future.
