FAQ

What is the maximum operating temperature for XC2361B40F80LRABHXUMA1?

The device is qualified per AEC-Q100 Grade 2, supporting continuous operation from −40°C to +105°C ambient temperature. Thermal derating begins above 105°C case temperature, and junction temperature must remain below 150°C under all operating conditions per datasheet Section 5.2.

Does XC2361B40F80LRABHXUMA1 support JTAG debugging in production?

Yes - it includes full IEEE 1149.1 JTAG support via TRST/TCK/TMS/TDO/TDI pins, enabling boundary-scan testing, flash programming, and real-time on-chip debugging using Infineon's DAS and Lauterbach tools. Debug access remains enabled post-production unless disabled via secure boot configuration.

Can the on-chip ADCs perform simultaneous sampling across all 16 channels?

No - the dual ADCs support synchronized start triggers but share a single conversion pipeline; true simultaneous sampling is limited to two channels (one per ADC). Up to 16 channels can be scanned in sequence with <1 µs per conversion and hardware-controlled sequencing via CAPCOM2 or PEC.

Is external memory expansion supported, and what bus widths are configurable?

Yes - the External Bus Controller supports up to 12 Mbytes address space with programmable chip-selects. Data bus width is selectable per region as 8-bit or 16-bit; address bus width is configurable from 16 to 24 bits, and bus timing (wait states, setup/hold) is fully software-defined per chip-select zone.
