FAQ
What is the maximum operating temperature for XC164CS32F40FBBAFXQMA1?
The device is qualified for industrial temperature range −40 °C to +125 °C ambient, with junction temperature limit of +150 °C. Thermal derating begins above +105 °C ambient, requiring PCB copper pour and thermal vias under the exposed pad to maintain reliability.
Does XC164CS32F40FBBAFXQMA1 support JTAG debugging?
Yes, it supports IEEE 1149.1-compliant JTAG interface for boundary-scan testing and on-chip debugging via Infineon's DAS (Debug Access Server) protocol. The JTAG port shares pins with Port 0.0–0.3 and requires dedicated debug enable sequence during reset.
Is the on-chip Flash memory protected against unauthorized readout?
Yes, Flash protection is implemented via three independent security levels: Level 0 (unprotected), Level 1 (read protection enabled), and Level 2 (full protection including debug access disable). Protection is activated by writing specific keys to the Flash configuration register during programming.
Can XC164CS32F40FBBAFXQMA1 operate from a 3.3 V supply only?
No. The device requires separate 3.3 V for analog circuits (VDDA) and 5.0 V for digital I/O (VDD), with internal regulators generating core voltage. Operating VDD below 4.5 V violates absolute maximum ratings and may cause undefined behavior in CAN transceiver and I/O drivers.
