FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The SAK-XC2265N-24F40L AA achieves a maximum CPU clock frequency of 80 MHz, resulting in a 12.5 ns instruction cycle time. This is enabled by its five-stage pipeline architecture and internal PLL, which multiplies an external 10 MHz crystal input. All integer ALU operations execute in one cycle at this frequency, as confirmed in Section 1.1 and Table 4.7.2.1 of the datasheet.

Does this MCU support functional safety standards such as ISO 26262?

Yes - the SAK-XC2265N-24F40L AA includes hardware features required for ASIL-B compliance: ECC-protected Flash and SRAM, Memory Protection Unit (MPU), lockstep-capable peripherals (e.g., CCU6), and comprehensive self-test capabilities documented in Infineon's Safety Manual for XC2000. It is qualified per AEC-Q100 Grade 1 and supports diagnostic coverage up to 90% for memory and clock monitoring.

How many CAN interfaces does it integrate, and what protocol versions are supported?

The device integrates two independent MultiCAN modules compliant with CAN 2.0B specification (ISO 11898-1), supporting both standard (11-bit) and extended (29-bit) identifier frames, bit rates up to 1 Mbps, and hardware message filtering with 32 message objects per channel. No CAN FD or ISO 11898-2 physical layer is integrated - external transceivers are required.

What debug and programming interfaces are available?

SAK-XC2265N-24F40L AA supports on-chip debug via JTAG interface compliant with IEEE 1149.1, with full OCDS (On-Chip Debug Support) functionality including real-time trace, hardware breakpoints, watchpoints, and memory inspection. Programming is performed through JTAG or serial bootloader using USIC channels; no SWD or proprietary debug port is present.
