LC703200AW is a Speech Processing LSI which equips original DSP, ADC/DAC, PCM Interface, I
C Interface and Flash memory. The LSI realizes speech processing functions such as Noise Canceller, Voice Speed Control, S-LIVE (Original Low Boost), Center Enhancement and Stereo Enhancement. And the LSIRealize small standalone system by supporting Timer and many I/O functions.
