New µC Precision32

09 March 2012 - 06:40 PM

Hello,

You know new Silabs µC 32-bit Précision32 ?

With USB 2.0 or not that seems well suited to some needs of OPENPILOT.

It incorporates many specific modules such :
- low power 22mA at 80Mhz
- PLL Clocks 1-80MHz. (Crystal less)
- two crossbars for assigning modules to  pins. Facilitates the design of CIs. Economy; $ 1.50 on  average by CI.
- pins 3.3V or 5V
- integrated regulator. Can pilot 5V 1A. Current measurement.
- 6 pins 1.8V..6V/300mA can driving power MOSFETs directly by  PWM/sine wave or another
- two  comparators LP integrated . Reference can be internally controlled .
- ... and other

With this we would certainly  make compact controllers for brushless motors  ....

IDE (+GCC)) and  Application Builder can be downloaded  from the site.
