Frequently asked questions
What does the 105°C operating temperature mean for a sealed IP67 enclosure?
The 105°C rating is the absolute maximum ambient under the JESD51-3 thermal test board conditions. In a sealed enclosure the internal ambient will exceed the external ambient; the junction temperature depends on the thermal resistance from the exposed pad through the PCB vias to the enclosure airspace. Model the pad thermal path before specifying the enclosure — the 105°C Ta is not a licence to run the part at the package limit in a sealed box without derating.
What I/O count is left for a fieldbus codec after the peripherals are mapped?
29 I/O is the gross count. A SPI codec consumes at minimum two pins (MOSI/MISO) plus a chip-select; a UART codec consumes two pins; an I²C host consumes two. With the ADC taking 12 channels and the debug interface occupying a small subset, the free GPIO count for discrete signalling or additional fieldbus daisy-chaining narrows significantly — the I/O map must be pinned out before the PCB layout is fixed.
