PSoC 5, 3 & 1 MCU

Valued Contributor

Hi all, i had been trying to run the CY8CYKIT-059 (device CY8C5888LTI-LP097) at 80 MHz, found this thread about it:

   

http://www.cypress.com/forum/psoc-creator-software/how-clock-psoc5lp-80-mhz

   

At least the above link confirm that i should be able to speed up to 80 MHz.

   

Also find this page that "explain" the procedure to speed the PSoC 5LP up to 67 MHz and 79 MHz

   

http://airsupplylab.com/index.php/learn/14-psoc5/15-psoc-setting-cpu-frequency-of-psoc-5lp-to-67mhz-...

   

So i did a try and the max MCU speed i'm able to run without warnings is 62 MHz, then if in the System tab of the .cydwr file i choose a working temperature of 0 - 85°C i can go up to 64MHz.

   

Attached an screenshot of the Static Timing Analysis Report where as far as i can understand i will not being able to run more than 64 MHz and the Clock Configuration i'm using.

   

Are there more steps to make this works?

   

Thanks in advance

Found the reason, silly me, i didn't read the whole PWM component datasheet, i found the explanation on:

   

* DC and AC Electrical Characteristics (UDB Implementation)

   

16bits PWM can run up to 43MHz, so i changed the clock of the PWM instance on the schematic and the warning goes away.
