The paper describes UMC CMOS 0.18 pm (1.8 V) implementation of OctaLynx D microcontroller. The processor is 8-bit RISC structure with built-in Dynamic Thermal Management Unit cooperating with Temperature-Controlled Oscillator. The Dynamic Thermal Management Unit consists of clock source multiplexer, thermal interrupts control unit and special registers containing information of present chip temperature, oscillator frequency control signal and status/control bits. Processor core was written in Verilog hardware description language and designed in top-down technique while memories and analogue parts were designed in full custom technique. The system was fabricated and tested in the laboratory equipped with the thermal chamber. Some test results and software prepared for the microcontroller are presented.
