DV 01:59 PM Software Development: RE: PWM signal generation.

Hi Costas,
Is it acceptable to just have the fan always on at max RPM? If so then a PWM isn't required and you can just plug a fan into J3 and you don't need to worry about PWM logic.
If you do want to control the speed of the fan ... Daniel Vincelette

CH 03:27 PM Software Development: PWM signal generation.

We would like to use a cooling fan on the A10 FPGA of the MitySOM-A10S.
We plan to connect the fan to the J3 connector.
How do we generte the PWM signal to control the fan?
And, could you suggest any of the shelf stick on fans to use ... Costas Hatzinikolaou

DV 02:49 PM FPGA Development: RE: battery-backup.

Hi Costas,
It does not. The MitySOM-A10S doesn't support battery backed up volatile security keys. In order to use the security feature of the Arria 10 you would need to use the one time programmable non-volatile memory for the key st... Daniel Vincelette

CH 01:45 PM FPGA Development: battery-backup.

I understand the the Real Time clock is connected to the VBAT battery voltage input pin of J4 connector in the MitySOM-A10S card.
Does the battery also provide backup for the RAM locations where the volatile security keys are stored?
