Frequently asked questions
What temperature range does the -A2 variant support?
-40°C to 85°C ambient (TA). This matches the industrial temperature band expected for non-climate-controlled enclosure panels, but the 100-LQFP thermal characteristics must be verified against the enclosure thermal model for continuous operation at the upper limit.
Can I socket the 100-LQFP for field replacement?
The 100-LQFP at 0.5mm pitch is not practically field-socketed at this pin count. MRO stock replacements require either pre-socketed boards or a full rewire to a different package footprint.
