Industrial BS2sx or BS2p24

achilles03

What components would I need to swap out on the 'sx or 'p in order to allow it to operate down to -20C (preferably -40C)?· I'm not sure if the resonator is the limiting factor, or if there are others.

Thanks for the help!

You could individually test a BS2p or BS2sx at the low temperatures, and it will probably work okay. The Ubicon CPU and the eeprom are already rated for -40 degrees, but the voltage regulator is commercial, so you could drop in an LT1121I5. I don't know about the resonator.

My BS2pe based data loggers are constructed with 100% industrial rated components:

It also has the AT45DB041 flash memory with RAM buffers, that allows for data streaming that might be relevant to a separate question you had about rapid memory access.
