ISD4004 series working voltage, monolithic 3V recording time 8 to 16 minutes, timbre, suitable for mobile phones and other portable electronics. Chip design is based on all the operation must by micro controller control, operation orders through serial munication interface SPI into. This paper summarizes the principle of voice recording circuit, and introduces the function of speech on the basis of recording system, puts forward the general structure of the system. Recording system for the recording, playback part of the overall design scheme is demonstrated. This paper introduces microcontroller AT89C52 single applications in system, the application system were analyzed each part of hardware and software realization.This design is to plete a reliable and stable working voice recording circuit. The design is simple in structure, reliable control and facilitate promotion.
