LC703200AW

Ordering number : EN*A2234 LC703200AW Advance Information CMOS LSI Speech Processing IC http://onsemi.com Overview LC703200AW is a Speech Processing LSI which equips original DSP, ADC/DAC, PCM Interface, I2C 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. Features 1) DSP Block 32bit DSP : Max Frequency = 68MHz, Power Save Mode Support 2) I2C Interface : Master/Slave : 1ch 3) 24bit ADC/DAC : 2ch, Fs = 8kHz / 11.025kHz / 12kHz / 16kHz / 22.05kHz / 24kHz / 32kHz / 44.1kHz / 48kHz 4) PCM Interface : Master mode 2ch, I2S, Left/Right Justified, Long frame Sync., Short Frame Sync. Fs = 8kHz / 11.025kHz / 12kHz / 16kHz / 22.05kHz / 24kHz / 32kHz / 44.1kHz / 48kHz Note : Slave mode only support PCM Interface, it doesn’t support ADC/DAC. 5) TIMER/PWM (MTM) : 6ch(resolution 16bit) TIMER (PTM) : 1ch(resolution 16bit) 6) WDT : 1ch (Max period 32.7S at 8.192MHz oscillation) 7) SIO : 2ch (8bit/16bit mode) 8) External interrupt request input : 8ch 9) GPIO : 21port (Including CPU I/F, SIO, PCM I/F, PWM/TIMER, INT2B - INT7B) 10) MIC AMP : 2ch, Gain : 30dB / 27dB / 24dB / 21dB / 18dB / 15dB / 12dB / 0dB Including MIC bias circuit 11) Oscillation frequency : 8.192MHz / 11.2896MHz / 12.288MHz 12) Supply Voltage : from 3.0V to 3.6V (IO, OSC, PLL), 1.5V±10% (Internal ...
