UPD17071GB-012

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 cassette recorder. FEATURES Preset memory Three bands: FM, AM, and Japanese TV (1 to 12 channels) 10 stations for each band, totaling 30 stations Watch function 12-hour or 24-hour indication Alarm function Outputs alarm sound at set time every day Sleep timer function Turns off radio after set time (Time can be set in a range of 30 to 120 minutes in units of 30 minutes.) Last channel memory One station for each band, totaling 3 stations Tuning function Manual seek/auto seek Auto store memory Preset memory call Low-voltage operation VDD = 1.8 to 3.6 V LCD controller/driver (1/4 duty, 1/2 bias, 3.1-V driven, frame frequency: 62.5 Hz) ORDERING INFORMATION Part Number Package 56-pin plastic QFP (10 × 10 mm, 0.65 mm pitch) µPD17071GB-012-1A7 The information in...
