There just isn't enough data for the F2013's 16bit > converter. so how do think other engineers design MSP430 products without this info? Same problem with the AVR datasheets. Design by experimentation is a poor design method, in my book...

On my desk, there are lots of developments tools connected to the windown 98 pc via rs232. At a corner, there is a MSP430 development kits (require XP/USB) sitting there, waiting for one of two things: 1. I upgrade to XP or 2. TI downgrade to Win98/rs232. I don't see either one happening soon.

Designed > by yours truly :-) How long ago did you design it? 20 years ago there was little other choice than 8051. It was already sort of a microcontroller, even though it needs external ram/rom. Ten years ago - still a valid choice, but the arena is getting smaller and smaller for the 8051. I agree it can still be a very valid choice today, for typically very less demanding tasks. Like a pellet heater. Damn if I know what a pellet heater is. > Jim mentioned that the 80C51 runs around a billion/year. Where do you > think these are going? Is someone eating them? A billion. With such large numbers and nothing to compare it against, I don't know if I should be impressed or not. Maybe a booming sales in pellet heaters is the cause of all this. -- Thanks, Frank.

One of the advantages of this series is the huge supply voltage range, doing away with the need for voltage regulation in most designs. -- Regards, Joerg http://www.analogconsultants.com |
