RTC Battery Type for S10 SoC Dev Kit?

[jwdonal]

I have a S10 SoC Dev Kit. I’d like to use the onboard RTC for keeping proper time in Linux between power cycles. However, I don’t know which battery type is required in the BT1 slot on the board. I incorrectly assumed it was a CR2032 which is what I’m familiar with for RTC but a CR2023 isn’t even close to fitting. The required battery needs a much smaller diameter than a 2032 and also needs to be thicker than a 2032. Can someone please tell me what the expected battery type/model/size is?

Hi Sir

Welcome to INTEL forum. May we know, is this the board that you refer to? https://www.intel.com/content/www/us/en/programmable/products/boards_and_kits/dev-kits/altera/stratix-10-soc-development-kit.html

Hi

Based on my understanding, most dev kit using (Energizer 357-303HVZ Lithium coin battery) https://data.energizer.com/pdfs/357-303ZB.pdf

You should be able to find the existing battery full part number (to clarify the spec) from dev kit BOM list. Example below is the BOM list path from dev kit installer

• stratix10_1sx280uf50 >> board_design_files >>BOM
