#144070 - Memory of AT89C2051 after reset |
Hello all,
I want to write a program for AT89C2051 to count an event but I want the last value of the counter to be saved in memory so to continue from the last saved value after restart the mcu. Can this be implemented in RAM memory? Is it possible and how? Any suggestion? |

| this is relatively complicated... | 01/01/70 00:00 | |
| Why no reset during low power? | 01/01/70 00:00 | |
| during active reset the oscillator is running... | 01/01/70 00:00 | |
| power back up? | 01/01/70 00:00 | |
| Oh, certainly... | 01/01/70 00:00 | |
| thanks | 01/01/70 00:00 | |

| options? | 01/01/70 00:00 | |
| my way of doing this... | 01/01/70 00:00 | |
| Then jus a RAM chip would work | 01/01/70 00:00 | |
| wouldn't it be easier and safer with serial EEPROM | 01/01/70 00:00 | |
| Maybe | 01/01/70 00:00 | |
| why not FRAM | 01/01/70 00:00 | |
| Combination of Technologies.... | 01/01/70 00:00 | |
| SRAM | 01/01/70 00:00 | |
| I don't think so | 01/01/70 00:00 | |
| this is not matter of "thinking"! | 01/01/70 00:00 | |
| OK, an another gotcha | 01/01/70 00:00 | |

| no | 01/01/70 00:00 | |
here is the best chip for u! | 01/01/70 00:00 |
