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
• Last channel memory
One station for each band, totaling 3 stations
• Tuning function
• Manual seek/auto seek
• Auto store memory
• Preset memory call
• LCD controller/driver
(1/4 duty, 1/2 bias, 3.1-V driven, frame frequency:
62.5 Hz)
• 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.)
• Low-voltage operation
VDD = 1.8 to 3.6 V
