FAQ

What is the maximum operating frequency of the MK10DX128VLF5?

The MK10DX128VLF5 operates at a maximum core frequency of 50 MHz. This speed is specified under full voltage and temperature range conditions and enables deterministic real-time control while maintaining ultra-low-power efficiency. The MK10DX128VLF5 achieves this using its ARM Cortex-M4 core with integrated flash accelerator and bus matrix, ensuring consistent instruction throughput without external clock multiplication.

Does the MK10DX128VLF5 support CAN FD or only classical CAN?

The MK10DX128VLF5 supports only Classical CAN 2.0B - not CAN FD. Its two CAN modules implement full CAN 2.0B compliance with hardware message filtering, FIFO buffering, and bit rates up to 1 Mbps. CAN FD functionality requires different peripheral IP and is not present in the K1x family; users requiring CAN FD should consider later-generation S32K or i.MX RT devices.

How much EEPROM-equivalent storage does the MK10DX128VLF5 provide via FlexMemory?

The MK10DX128VLF5 provides 32 KB of FlexNVM that can be configured as user-segmentable byte-erasable EEPROM. This space is distinct from main flash and supports true EEPROM semantics: individual byte writes and erases without block-level constraints. The MK10DX128VLF5 allows runtime reconfiguration between EEPROM and additional program/data space, enabling flexible data-logging and parameter storage.

Is the MK10DX128VLF5 pin-compatible with other Kinetis K1x MCUs in the same package?

Yes, the MK10DX128VLF5 is pin-compatible with other K1x MCUs offered in the 48-pin QFN (7×7 mm) package, including MK10DX32VLF5 and MK10DX64VLF5. Pin functions, power domains, and peripheral mappings are identical across these variants - allowing scalable memory upgrades without PCB redesign. However, feature availability (e.g., FPU, cache size, FlexNVM allocation) differs and must be validated per application.

What debug interfaces does the MK10DX128VLF5 support?

The MK10DX128VLF5 supports SWD (Serial Wire Debug) and JTAG interfaces for full-featured debugging and programming. It includes an ARM CoreSight debug architecture with hardware breakpoints, watchpoints, and real-time trace capability via SWO. These interfaces are accessible through standard debug probes compatible with Eclipse-based IDEs, IAR Embedded Workbench, and Keil MDK - enabling efficient firmware development and validation of the MK10DX128VLF5.
