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 (V^DD= 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

Watch function

•

Three bands: FM, AM, and Japanese TV (1 to 12

channels)
