The CPU uses a three-stage instruction pipeline that allows execution of up to one instruction per clock cycle, or up to 20 million instructions per second (MIPS) at a clock rate of 20 MHz. The family of CompactRISC™ microcontrollers are general-purpose 16-bit microcontrollers based on a Reduced Instruction Set Computer (RISC) architecture. The device operates as a complete microcomputer with all system timing, interrupt logic, flash program memory or ROM memory, RAM, EEPROM data memory, and I/O ports included on-chip. It is ideally suited to a wide range of embedded controller applications because of its high performance, on-chip integrated features and low power consumption, resulting in decreased system cost.
