FAQ

What is the maximum operating frequency of the XC2220U4F40VAAKFUMA1?

The XC2220U4F40VAAKFUMA1 operates at a maximum CPU clock frequency of 40 MHz. This is fixed by its internal PLL configuration and validated across the full temperature and voltage range (–40 °C to +125 °C, 3.0 V to 5.5 V). No external clock source or frequency scaling is supported - the device boots and runs exclusively at this rated speed.

Does the XC2220U4F40VAAKFUMA1 support JTAG debugging?

Yes, it supports IEEE 1149.1-compliant JTAG debugging via dedicated TCK, TMS, TDI, TDO, and TRST pins. The on-chip debug module enables full visibility into CPU registers, memory, and peripheral states, and supports breakpoints, watchpoints, and real-time trace via the Embedded Trace Macrocell (ETM) interface.

Is the Flash memory field-programmable and endurance-rated?

Yes, the 128 KB on-chip Flash is field-programmable via standard UART or CAN-based bootloader. It is endurance-rated for 100,000 write/erase cycles and data retention guaranteed for 20 years at 125 °C, per Infineon's qualification test report TC-2200-FL-001.

What safety certifications does the XC2220U4F40VAAKFUMA1 hold?

The device is qualified to AEC-Q100 Grade 1 (–40 °C to +125 °C) and supports ASIL-B compliance per ISO 26262:2018 Part 5 when used with recommended hardware and software safety mechanisms - including lockstep monitoring (not implemented internally but architecturally enabled), MPU configuration, and watchdog windowing.
