Hi,

I need to use a MMC card for a datalogger/control system in an industrial environment where temperatures can go upto 45 degC .

Can the MMC card work in such environments ??

I read the specs for the MMC card , the operating temperature is mentioned as between -25 degc/85 degc .

Does this apply to any MMC card ??

thanks

The exact temperature range is up to the manufacturer of the card you are using. But 45C is not an extreme temperature. Look at datasheet from several manufacturers and see what the usual limits are.

Thanks for the reply,

Actually this is the first time I would be using the card for an industrial application, so I was worried.

Also is it essential to use the MMC card connector, or will a floppy type connector do??

thanks

Thanks for the reply.

For my application the card need not be removed, so maybe it could be soldered directly to wires.

Will this damage the card ??

thanks
