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.

FEATURES

• 17K architecture

: General registers

• Program memory (ROM)

: 3K bytes (1528

× 16 bits)

• Data memory (RAM)

: 97

× 4 bits

• General-purpose I/O ports

: 12

• Minimum required peripheral hardware is built into the chip.

• LCD controller/driver

: 9 segments

× 4 commons

• PLL frequency synthesizer and 220-MHz (MAX.) prescaler

• Clock generator port

• Low-voltage operation

: VDD = 1.8 to 3.6 V (TA = –10 to +50

°C)
