PD17072 or 17073.

Dual modulus prescaler (230 MHz max.), programmable divider, phase comparator, charge pump

General-purpose I/O ports, LCD controller/driver, serial interface, A/D converter, BEEP, intermediate frequency

(IF) counter

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

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

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

Because the PD17072 and 17073 can operate at low voltage (V

PD17072 and 17073 are low-voltage 4-bit single-chip CMOS microcontrollers containing hardware ideal for

Unless otherwise stated, the PD17073 is taken as a representative product in this document.
