DATA SHEET µPD178024GC-051 8-BIT SINGLE-CHIP MICROCONTROLLER WITH ON-CHIP PRESCALER, PLL FREQUENCY SYNTHESIZER, AND IF COUNTER FOR AUTOMOTIVE FM/MW/LW RADIO WITH CD PLAYER MOS INTEGRATED CIRCUIT 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, multifunction 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 remotecontroller signal) Rotary commander Front panel control • • • • • • • • • • • • • • ORDERING INFORMATION Part Number µPD178024GC-051-8BT Package 80-pin plastic QFP (14 × 14 mm, 0.65 mm pitch) The information in this document is subject to change without notice.
