Power up the device(CYCLONE 5) in temperature under zero

[sn681]

we are using in our board the device CYCLONE 5 - 5CSEBA5U23,
when we are trying to power up the device in temperature under zero( -5 cel),
we are getting the " altera_load" failed with error code -2" and the "conf_done" stays low.
If the board is power up in a positive temperature , and we are cooling the board, the device working fine.
We check all signals control , the are setting ok.

Hi,

Have you follow our userguide when configuring and power up the FPGA?

Hi Aiman,

We designed our board according to Intel's recommendation.

The device works great in all temperatures, but when we trying to turn it on at temperatures below zero

we are getting the " altera_load" failed with error code -2".

Is there anything we can try to resolve this ?

Hi,

Thank you for the update. Can you provide us the screenshot of the failure/error code?

Also, please provide the full device OPN.

Hi,

If you ae using commercial device, the operating junction temperature should be between 0 to 85C.

Hi,

1. I have attached a screenshot of the error code.

2. what do you mean when you wrote "full devic OPN"?

3.We use CYCLONE V - 5CSEBA5U23I7N, the operating junction temperature should be between -40 to 100C.

Hi,

-How many devices show the same failure when power up using below 0cel?

-Please share the top marking for the failing devices.

 Hi Aiman,

- We tested 10 devices and 8 of them showed an failure when power up  below 0cel.

-You want me to share the top marking of the CYCLONE V - 5CSEBA5U23?

[sn681]

Hi Aiman,

Is there any update?

Hi Aiman,

See attached top marking of the CYCLONE V - 5CSEBA5U23.

Hi,

Apologize for the delay in response.

Can you check:

• Power up status such as
• power rails all power up correctly
• Measure the voltage during the power up
• Also, different component on the board can also effect the power up
• And, is there any changes when power up between those 10 devices? Are the 10 devices using the same board or different board?

Regards,

Aiman

Hi Aiman,

-We check all power rails there is no change when power up below 0cel.

-We measure the voltage during the power up, the are setting ok.

-The signal "conf_done" stays low.

-There are no different components between the boards, the 10 devices using the same board.
