疑難芯片解密-ATtiny28L解密

來源：IC解密的了解，我們提供C8051F713單片機的主要功能特征介紹以供參考，以便為后續(xù)的技術合作和項目溝通提供方便。針對芯片解密，耐斯迪解密事業(yè)部早先就曾針對客戶的解密需求進行過方案開發(fā)，而近期在該芯片解密中的技術突破將為更多客戶帶來實實在在的利益。
　　以下是我們對ATtiny28L單片機的簡單介紹供各位參考：
　　The ATtiny28 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture.By executing powerful instructions in a single clock cycle, the ATtiny28 achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general-purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
