Mainly by the FM radio FM/AM radio IC CXA1019, PLL and frequency synthesizer BU2614 and SCM AT98C51 composition. AT98C51 microcontroller for the control of the radio to the core, to achieve full frequency search, specify the frequency range of search and manual search radio station the radio also uses a digital potentiometer (X9511) to control the volume. Carrier frequency with LCD display and clock and other information, significantly reducing system power consumption. Machine to achieve 3V supply, the use of E2PROM (AT24C04) storage station, also increased the stereo decoding.
