4-BIT SINGLE-CHIP MICROCONTROLLERS WITH
DIGITAL TUNING SYSTEM HARDWARE
DESCRIPTION
The µPD17012 is a 4-bit single-chip CMOS microcontroller equipped with hardware for digital tuning systems.
The µPD17P012 is a version of the µPD17012 with one-time PROM instead of mask ROM.
The user can write programs to the µPD17P012 once, and it is ideal for experimental production of the µPD17012
during system design or small-scale production.
This series employs a 17K architecture CPU that 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. This series therefore ideal for configuring a high-performance, multi-
functional digital tuning system on a single chip.
