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 SC14404 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 kilobyte F lash is integrated for parameter and number storage. n n n n n n n n n n n n n n n n n n n n n 3V upto 5.0V battery monitor input. Advanced battery management unit Very low power in active and paging mode. Embedded 16 bit CompactRISCT M Micro Controller. (CR16B) with programmable clock speeds. 4k byte memory mapped Flash 320 kbyte Flash or factory programmed ROM FLASH. ACCESSBUSTM or MICROWIRE T M interfaces 5,5 kilobyte on-chip Data Memory. One full duplex ADPCM transcoder. On-chip 14-bit linear CODEC. 14 upto 44 dB gain differential microphone input buffer. 100 Ω loudspeaker driver. Software controlled gain on audio input and output. Peak hold ADC for RSSI measurement. Five general purpose inputs can be multiplexed on an 8 bit ADC with selectable ranges. On-chip dedicated TDMA instruction co-processor which supports 1.152 MHz, 0.576 MHz and 0.288 MHz bit rates. Seven programmable control signals for radio front end. Full and double slot, protected and unprotected Bfields. Duplex quality handsfree operation. Tone generator. Tones consisting of 3 frequencies can be programmed Linear PCM interface for external codec. Features n Integrated DECT Baseband transceiver optimized for GAP handsets according to ETS 300 175-2, 175-3 & 175-8. n Two on board low drop voltage regulators with 2.85V and 3.0- 3.8V (with external resistors the voltage can be determined) output. n 2V upto 3.6V battery input with onboard step up converter. ________________________________________________________________________________________________ System Diagram Note: ACCESSBUST M, MICROWIRET M and CompactRISCT M are trademarks of National Semiconductor Corporation.
