These are new members of the Freescale MC56F800 Digital Signal Controller (DSC) family. Article includes a roadmap and a chart of the low power modes. - Bill Giovino Executive Editor http://Microcontroller.com

Also the table lacks any 1uA entry at all.. ? -jg

not further criticizing Bill's article, I'm curious about the PGA performance. The "PGA Specifications" table in the preliminary technical data is at least confusing. I assume they mean 4LSB linearity error at higher gains, else the whole PGA were useless. But there is no indication about offset and noise. One ADC step at full gain is just 32uV (3V / 4096 / 32 is 23uV). It would be _great_, if these devices really contained a good PGA, since a good external PGA costs as much as a whole 56F800x. Any other microcontroller with a useful PGA? Oliver -- Oliver Betz, Munich despammed.com might be broken, use Reply-To:
