D17006AGF-011

PRELIMINARY DATA SHEET MOS INTEGRATED CIRCUIT µ PD17006AGF-011 4-BIT SINGLE-CHIP MICROCONTROLLER WITH PRESCALER, PLL FREQUENCY SYNTHESIZER, AND IF COUNTER FOR AUTOMOBILE FM, MW, AND LW RADIOS DESCRIPTION The µPD17006AGF-011 is a 4-bit CMOS microcontroller for digital tuning and can receive European FM, MW, and LW bands. It contains a prescaler (150 MHz MAX.), PLL frequency synthesizer, and IF counter. This microcontroller supports European Radio Data System (RDS) and implements various RDS functions, so that it can configure with a single chip a high-performance FM, MW, or LW tuner such as that for luxury automobile stereo systems. In addition, an RDS decoder is realized as a software library, so that the system using the µPD170006AGF011 can eliminate one IC chip as compared with existing systems. FEATURES q Preset memory Five stations each for four bands, FM1, FM2, FM3, and AM (shared with MW and LW), totaling 20 stations q RDS function Broadcasting station name display (PS) AF operation AF list of up to 25 stations can be loaded. Supports METHOD A/B Traffic information standby function (TP, TA) Alarm function (PTY = 31) PTY seek function (broadcasting program identification information) CT function (time adjustment function) RDS memory AF data for eight stations can be stored for 22 types of PI codes. EON function RDS memory AF data update function EON station traffic information selection function RDS decode function q Last channel memory...
