#180203 - increase the clock until lockup Responding to: ???'s previous message |

When you overclock a chip, the chip itself can lock up or create general havoc all on its own. Hi Per Well, the Atmel recommend a max of 20 MHz, I was quite surprised when I replaced the 20 MHz crystal for a 30MHz and the AVR carried on running no problems, obviously mcu manufactures specify a safe limit but if the chip don't lock up at 1.5x clock speed then whats the problem?., yes indeed the micro will consume more energy by increasing the clock but that depends on application surely?
