µPD17072,17073

4-BIT SINGLE-CHIP MICROCONTROLLER

WITH HARDWARE FOR DIGITAL TUNING SYSTEM

DESCRIPTION

µPD17072 and 17073 are low-voltage 4-bit single-chip CMOS microcontrollers containing hardware ideal for

organizing a digital tuning system.

The CPU employs 17K architecture and can manipulate the data memory directly, perform arithmetic operations,

and control peripheral hardware with a single instruction. All the instructions are 16-bit one-word instructions.

As peripheral hardware, a prescaler that can operate at up to 230 MHz for a digital tuning system, a PLL frequency

synthesizer, and an intermediate frequency (IF) counter are integrated in addition to I/O ports, an LCD controller/driver,

A/D converter, and BEEP.

Therefore, a high-performance, multi-function digital tuning system can be configured with a single chip of

µPD17072 or 17073.

Because the µPD17072 and 17073 can operate at low voltage (VDD = 1.8 to 3.6 V), they are ideal for controlling

battery-cell driven portable devices such as portable radio equipment, headphone stereos, or radio cassette

recorders.
