Is there any 1.8V UART to RS232 Level translator? out there in the market.
possibly, but that would have to be a multiple volatge supply chip, I can not see a charge pump pumping 1V8 to 232 levels. The simple way would be to level convert and use a 3V3 or 5V 232 chip. Wlcome to te fun world of multiple voltage rails. Erik |

| Try digikey | 01/01/70 00:00 | |
| I read about some MOSFETs that switch at <1.5V | 01/01/70 00:00 | |
| why fiddle when there are dedicated chips? | 01/01/70 00:00 | |
| It depends on how many he needs, doesn't it? | 01/01/70 00:00 | |
| not really | 01/01/70 00:00 | |
| and what's price and availability in small quantit | 01/01/70 00:00 | |
