Overview
내가 ㅇ Semiconductor SD4002 4BIT MICRO CONTROLLER Description The SD4002 is CMOS LSI chips developed for world-wide FM / MW / LW tuning with PLL frequency synthesizer system.
The SD4002 can make a compact and high performance FM / MW / LW tuner with clock function for high-end car stereo, home stereo and so on because these CMOS LSIs are in 64-pin QFP package with built-in PLL frequency synthesizer, controller, 200 MHz prescaler, LCD driver and IF counter.
