#149710 - wide supply voltage Responding to: ???'s previous message |
Kai Klaas said:
Think only of the ground pin current of usual three pin voltage regulators, especially the low drop variants, for instance. This is why for the ultralow power MCUs it's absolutely necessary to have wide supply voltage range, so that NO regulator is needed for example for battery-powered applications. Atmel comes into mind in this respect... but not the '51s unfortunately :-( JW PS. One more thing, the absolute winners in the low power quest will be ROM based devices, as the FLASH is a classical power-sucker. |

| Who has the lowest-power 8051s...? | 01/01/70 00:00 | |
| the answer heavily depends... | 01/01/70 00:00 | |
| Benchmarks | 01/01/70 00:00 | |
| certainly... | 01/01/70 00:00 | |
| Just like any other benchmark, then. | 01/01/70 00:00 | |
| Something like this? | 01/01/70 00:00 | |
| I would like to know... | 01/01/70 00:00 | |
| did you see ... | 01/01/70 00:00 | |

| no, just | 01/01/70 00:00 | |
| 33uA | 01/01/70 00:00 | |
| you could always... | 01/01/70 00:00 | |

| This is often an academic question... | 01/01/70 00:00 | |
| wide supply voltage | 01/01/70 00:00 | |
| i think it's Maxim ... | 01/01/70 00:00 | |
| but why would you do it? | 01/01/70 00:00 | |
