Abstract: An embedded Micro-Controller Unit(MCU) system for mixed-signal processor is introduced in this paper. According to the request of systems reconfiguration, all the instructions stored in the EEPROM off-chip are transferred into the SRAM on-chip and executed. The MCU system is fabricated in SMIC 0.18 µm mixed-signal CMOS process with an area of 1.06 mm2. It operates from 1.8 V power supply. Measurement results show that all of the instructions are executed correctly and it can be used to configure the function of the mixed-signal processor in a way compatible with SPI protocol.

Key words: embedded Micro-Controller Unit(MCU), reconfiguration, mixed-signal processor
