PD17012
4-BIT SINGLE-CHIP MICROCONTROLLER WITH
DIGITAL TUNING SYSTEM HARDWARE
The
碌
PD17012 is a 4-bit single-chip CMOS microcontroller equipped with hardware for digital tuning systems.
The CPU employs 17K architecture and can directly manipulate the data memory, execute various operations,
and control the peripheral hardware with a single instruction. All the instructions are one-word 16-bit instructions.
Besides various I/O ports, an LCD controller/driver, A/D converter, D/A converter (PWM output), and BEEP output,
this microcontroller has a prescaler that can operate at up to 250 MHz, a PLL frequency synthesizer, and frequency
counter for digital tuning systems.
Consequently, a high-performance, multi-functional digital tuning system can be configured on a single chip.
In addition to the
碌
PD17012, a one-time PROM version for program evaluation and small-scale production, the
碌
PD17P012, is also available.
