4-BIT SINGLE-CHIP MICROCONTROLLER FOR PORTABLE RADIOS
The µPD17015 is a super low-voltage 4-bit single-chip microcontroller for digital tuning applications. It features
a prescaler that can operate at frequencies up to 220 MHz, a PLL synthesizer, and an LCD controller/driver, all
configured in one chip.
Since, for its CPU, the µPD17015 adopts a 17K architecture which allows data memory to be manipulated directly
without accumulators, programming efficiency is enhanced. Each instruction is 16 bits (one word) long.
Since this microcontroller can operate at low voltages (VDD = 1.8 to 3.6 V), it is ideal for controlling portable, battery-
powered units such as portable radios, headphone stereo sets, and radio-cassette players.
