8-BIT SINGLE-CHIP MICROCONTROLLER WITH ON-CHIP
PRESCALER, PLL FREQUENCY SYNTHESIZER, AND IF COUNTER
FOR AUTOMOTIVE FM/MW/LW RADIO WITH CD PLAYER
The µPD178024GC-051 is an 8-bit CMOS microcontroller for use in digital tuners designed to receive the
European and USA FM, MW, and LW bands. It incorporates a prescaler, PLL frequency synthesizer, and IF counter.
The device has various CD player control functions and enables the configuration of a high-performance, multi-
function FM/MW/LW tuner with CD player, such as an automotive stereo system, using a single chip.
FEATURES
• Preset memory
Stores six stations in each of the FM1, FM2, FM3,
AM1 (shared by MW), and AM2 (shared between
MW and LW) bands, giving a total of 30 stations
• Last channel memory
One station per band, totaling 5 stations
• Tuning functions
• Manual seek/auto-seek
• Auto-storage
• Preset scan
• Auto-retuning
• LCD controller/driver (µPD16431A)
• Single power supply (VDD = 5 V ±10%)
• CD player control functions
• 8 cm/12 cm disc detection
• Track repeat
• Intro playback
• Random play
• Program playback
(with CD player (CDC-01KG) connected)
• Electronic volume control (TDA7313)
• Equalizer function (TA2078P)
• Remote-controller signal reception function
(µPD6121G is used for sending the remote-
controller signal)
• Rotary commander
• Front panel control
