SINGLE-CHIP MICROCONTROLLER WITH
ON-CHIP PRESCALER, PLL FREQUENCY SYNTHESIZER,
AND IF COUNTER FOR CAR-MOUNTED FM/MW/LW RADIO
DESCRIPTION
µPD17012GF-055 is 4-bit CMOS microcontroller for PLL frequency synthesizer-method digital tuning, which
is capable of receiving European FM, MW, and LW.
The external appearance is 64-pin plastic QFP in which the prescaler (150 MHz MAX.), PLL frequency
synthesizer, and IF counter are integrated. Also, since it can use various RDS (Radio Data System) functions
in the FM band, it is possible for a car-mounted stereo and the high-performance multi-functional FM, MW, and
LW tuner to be configured in a single chip.
FEATURES
• Can receive European FW, MW, and LW bands.
• Preset memory of 6 stations in FM1, FM2, and AM, respectively (thus totaling 18 stations)
• One last-channel station memory for each band, FM1, FM2, and AM
• Rich in station-select functions, such as selection of stations through MANUAL or AUTO-SEEK UP/DOWN,
preset memory scan, auto store memory (sorting stations with strong SD signals in the order of frequency),
etc.
• RDS decode function
• Traffic information stand-by (TA/DK stand-by) function
• µPD16431A is used for the LCD controller/driver
• Clock function with 12- or 24-hour display (No-clock also possible)
• Program name display function based on RDS-broadcast data
• AF function for 25 stations, handling methods A and B
• Supporting electronic volume
• Supporting detachable panel
• 5 V ± 10 %: single power supply
