DATA SHEET

PD17072,17073
4-BIT SINGLE-CHIP MICROCONTROLLER
WITH HARDWARE FOR DIGITAL TUNING SYSTEM
MOS INTEGRATED CIRCUIT
DESCRIPTION
碌
PD17072 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
碌
PD17072 or 17073.
Because the
碌
PD17072 and 17073 can operate at low voltage (V
DD
= 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.
