#151807 - not the old 'H' P89c51Rx2 Responding to: ???'s previous message |
Modern microcontrollers use non-volatile embedded memories, which can be erased and re-programmed up to 100 000 times. Fuses are nothing else but privileged locations in such non-volatile embedded memories (like EEPROM or Flash).
Not the old 'H' P89c51Rx2 that - now discontinued (two generations since then) - chip had an actual fuse for the 6/12 clock mechanism. Once blown that was it. Thus it is very confusing to refer to 'fuses' that can be 'fixed once they are blown' Ph.. eh NXP refer to "configuration bits" Erik |
