AVR® XMEGA® 8/16-bit Microcontrollers

Microchip AVR XMEGA 8/16-bit Microcontrollers are low-power, high-performance and peripheral-rich CMOS 8/16-bit microcontrollers based on the AVR enhanced RISC architecture. By executing instructions in a single clock cycle, the Microchip AVR XMEGA 8/16-bit Microcontrollers achieve throughputs CPU approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed. AVR XMEGA 8/16-bit Microcontrollers combine a rich instruction set with 32 registers that are directly connected to the arithmetic logic unit (ALU), allowing two independent registers to be accessed in a single instruction, executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs many times faster than conventional single-accumulator or CISC based microcontrollers.

Functional Safety Solutions

Microchip Technology Functional Safety Solutions offer robustness, reliability, and safety to end-products. In some application segments, these requirements are formalized and mandatory, while in others, they are implemented to differentiate the product and take the step from a good product to an excellent product. The standards for functional safety depend on the market that is targeted. Many standards support multiple levels of rigorousness, which are applied depending on the likelihood and severity of the hazard. The methods of addressing hazards range from detecting single failures and putting the system into a safe state to full redundancy, where failures should not only be detected but also corrected without any interruption or degradation of service.
