... if you don't have ... some ... source of backup power ... the only choice is a dedicated nonvolatile memory. Absolutely! The key word is Non-Volatile Besides standard EEPROMs ... I would like to direct your attention to RAMTRON's FRAM devices Note that there are also other vendors of FRAM devices, and a number of other non-volatile technologies. Note also that Ramtron have some non-volatile latches - you might be able to build a non-volatile counter from them... |

| Memory of AT89C2051 after reset | 01/01/70 00:00 | |
| 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 | |
| alternatives | 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 | |
| to Jan | 01/01/70 00:00 | |
| no | 01/01/70 00:00 | |
here is the best chip for u! | 01/01/70 00:00 |
