8-BIT SINGLE-CHIP MICROCONTROLLER WITH BUILT-IN
PRESCALER, PLL FREQUENCY SYNTHESIZER, AND IF COUNTER
FOR AUTOMOTIVE FM/MW/LW RADIO APPLICATIONS
The µPD178016GC-051 is an 8-bit CMOS microcontroller for use in digital tuners designed to receive the European
FM, MW, and LW bands. It incorporates a prescaler, PLL frequency synthesizer, and IF counter.
The device supports European RDS (Radio Data System), and offers many RDS functions. Thus, it enables the
configuration of a high-performance, multi-function FM/MW/LW tuner, such as an automotive stereo system, using
a single chip.
Because the device implements the RDS decoder as a software library, an RDS system can be configured by
combining the device with an RDS data demodulation IC µPC2539.
FEATURES
• Preset memory
• RDS functions
Stores six stations in each of the FM1, FM2, FM3, and • Built-in RDS decoder function
AM bands (the AM band is shared between the MW • Station name display (PS)
and LW bands), giving a total of 24 stations
• Last channel memory
• AF function
• Traffic information standby function (TP and TA)
One station per band, totaling four stations
• Tuning functions
• EON function
• CT function (automatic time adjustment)
• Manual seek/auto-seek
• Alarm function (PTY = 31)
• Auto-storage
• Preset scan
• Auto-retuning
• A µPD16431A is used as the LCD controller/driver
• Single power supply (VDD = 5 V ± 10 %)
• PTY seek function (program identification information)
• CD changer and logic tape deck control
• Electronic volume control
• Remote-controller signal reception function (a µPD6121G-
002 is used for sending the remote-controller signal)
