LC703200AW-8C99-H

DSP 32Bit 64Pin SQFP Tray

LC703200AW is a Speech Processing LSI which equips original DSP, ADC/DAC, PCM Interface, IC 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 LSI Realize small standalone system by supporting Timer and many I/O functions.
