INTRODUCTION
The SNL320 is a high performance 16-bit DSP base processor with 16MIPS CPU power. The internal 64K words hi-speed ROM already built-in a hi-performance software voice synthesizer to provides lot of voice effects. Such as hi-decompression engine to support from 1.5kbps ~ 29kbps compression rate for speech and music, multi-channel voice synthesizer to provides 8-channel wave-table melody, or support foreground 1.5kbps~29kbps and background 4-channel wave-table melody. The standard microprocessor interface allows SNL320 to extend its memory capability, or connect external device. We also built-in a Low Voltage Detector circuit for power management and a USB 1.1 interface for communication with PC.
