FAQ
What is the maximum operating frequency of the SAK-XC2236N-24F40L AA CPU?
The CPU achieves a maximum operating frequency of 80 MHz, corresponding to a 12.5 ns instruction cycle time. This is attained using the on-chip PLL with an external 1–20 MHz crystal input, and is validated across the full –40 °C to +125 °C temperature range per Infineon's V1.5 datasheet Section 4.7.2.1.
Does the SAK-XC2236N-24F40L AA support CAN FD?
No, it implements MultiCAN Rev. 2.0B only, supporting classical CAN up to 1 Mbit/s. While its 256 message objects and hardware filtering provide robust CAN 2.0B networking, it lacks the protocol stack, bit-rate switching, and extended data length features required for CAN FD compliance.
How is Flash memory protected against corruption during power loss?
Flash integrity is enforced via Error Correction Code (ECC) circuitry that detects and corrects single-bit errors and detects double-bit errors in real time. Additionally, the hardware CRC checker validates Flash content at boot or on-demand, and the MPU prevents accidental write access to protected sectors.
Is JTAG debugging supported on this part?
Yes, the device supports IEEE 1149.1 JTAG via dedicated TCK/TDO/TDI/TMS pins and includes On-Chip Debug Support (OCDS) for real-time trace, breakpoints, and memory inspection. Debug access is also available through the Device Access Port (DAP) for alternative toolchain integration.
