PRELIMINARY DATA SHEET MOS INTEGRATED CIRCUIT µPD17071GB-012 4-BIT SINGLE-CHIP MICROCONTROLLER WITH PLL FREQUENCY SYNTHESIZER CONTROLLER FOR PORTABLE FM/AM RADIO AND TV DESCRIPTION The µPD17071GB-012 is a CMOS microcontroller with an on-chip PLL frequency synthesizer for receiving international FM and AM and Japanese TV broadcasting.
In addition, because it includes a prescaler (230 MHz MAX.
), IF counter, and LCD controller/driver, it constitutes a high-performance, multi-function FM, AM, or TV tuner on a single chip.
Housed in a 56-pin QFP and driven by two dry cells at a low voltage (VDD = 1.
8 to 3.
6 V), the µPD17071GB-012 is ideal for creating a compact portable clock radio and radio c...
