General Description
SC14405 General Description
The SC14405 is a CMOS chip optimized to handle all the audio, signal and data processing needed within a DECT handset. An ADPCM transcoder, a very low power CODEC and Analog Frontend is integrated. Direct connections towards microphone and a (dynamical) loudspeaker are provided. Duplex quality handsfree operation is integrated.
The SC14405 is designed to fit to any radio design.
A dedicated TDMA controller handles all physical layer slot formats and radio control.
National Semiconductors standard CompactRISCTM CR16B 16 bit microcontroller takes care of all the higher protocol stack. 4 kByte Flash is integrated for parameter and number storage.
The SC14405 has an 125 segment LCD controller.
