功能安全性解決方案

Microchip Technology功能安全性解決方案可為終端產品提供穩健性、可靠性及安全性。在某些應用領域中，這些要求是正式及強制性的，而在其他應用領域，則是為了產品脫穎而出，讓產品從良好邁向完美。功能安全的標準取決於目標市場。許多標準支援多種嚴格等級，根據危險的可能性及嚴重程度套用這些等級。處理危險的方法包括檢測單個故障並將系統置於安全狀態，以及完全冗餘，其中不僅應該檢測故障，而且應該糾正故障，不中斷或影響服務。

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.
