UPD17010

DATA SHEET MOS INTEGRATED CIRCUIT µ PD17010 4-BIT SINGLE-CHIP MICROCONTROLLER WITH HARDWARE DEDICATED TO DIGITAL TUNING SYSTEM The µ PD17010 is a 4-bit single-chip CMOS microcontroller containing hardware for digital tuning systems. The CPU uses a 17K architecture and can directly manipulate the data memory and control various operations and peripheral hardware with a single instruction. All instructions are 16-bit 1-word instructions. As the peripheral hardware, a prescaler for digital tuning that operates at up to 150 MHz, PLL frequency synthesizer, and frequency counter, as well as many I/O ports, LCD controller/driver, 12-bit timer, A/D converter, D/A converter (PWM output), clock generator port are provided. Therefore, a high-performance digital tuning system with sophisticated functions can be configured with a single chip. The µ PD17P010 is available as a one-time PROM model of the µ PD17010. This one-time PROM model can be used for evaluation of the program of the µ PD17010 and small-scale production of the application system.
