According to 16 intelligences of MCU of SunPlus recording telephone
[Summary]:
16 MCU tools of Sunplus contain the special and strong programmable numerical speech signal processing identify the function and the DSP operation functions, this system makes use of its strong speech function to carry on the speech report number and the recording playbacks towards stiring into the telephone namely.The system is the lord to control the MCU with the SPCE061A 16 MCU of the Sunplus, matching with 1420 recording chips, the LCD manifestation mold piece, keyboard mold piece, DTMF to edit and translate the code etc. complete to stir telephone into the telephone the information carries on the DTMF/ FSK decoding manifestation, speech report number and flaps the bell signal of examination and count, hint the sound to broadcast, record sound the playback and hang the machine examination and record sound information manifestation etc..That system and have the tape recorder and reply to read the machine function, establish the recording, playback, stop three handses move the key, can at any time record into oneself need of information.Record sound the chip adoption ISD1420, can restore with the speech of the high quantity, nature, the automatic stanza electricity, don't consume the telecommunication interest to keep 100 years, record sound the period 100,000 times.Therefore can broadcast again and again saving.The FLASH RAM that pluses 32 K of inside the MCU of Sunplus save, total recording time of system can reach to be close to 25 minutes, can carry on dividing manies of page to record to go into to the recording information.That system operation is simple, the convenience is practical, science and technology content is high!
