UPD17017

DATA SHEET µPD17016, 17017 4-BIT SINGLE-CHIP MICROCONTROLLERS WITH DIGITAL TUNING SYSTEM HARDWARE MOS INTEGRATED CIRCUIT The µPD17016 and 17017 are 4-bit single-chip CMOS microcontrollers equipped with hardware for digital tuning systems. The CPU employs the 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. As the peripheral hardware, a prescaler that can operate at up to 150 MHz, PLL frequency synthesizer, and frequency counter for digital tuning systems, as well as many I/O ports, an LCD controller/driver, A/D converter, and D/A converter (PWM output) are provided. Therefore, a high-performance, state-of-the-art digital tuning system can be organized with a single chip. In addition to the µPD17016 and 17017, a one-time PROM model for program evaluation, the µPD17P005, is also available.
