FAQ

What is the maximum operating frequency of the MK28FN2M0AVMI15?

The MK28FN2M0AVMI15 operates at up to 150 MHz in High-Speed Run (HSRUN) mode with VDD_CORE regulated at 1.33–1.47 V. This frequency is sustained under full peripheral enablement and thermal conditions up to +105°C ambient, as verified in the Rev. 4 datasheet's power consumption tables. The MK28FN2M0AVMI15 achieves this using its internal PLL with MCG PEE mode configuration and 32 MHz crystal reference.

Does the MK28FN2M0AVMI15 support execution-in-place (XIP) from external flash?

Yes, the MK28FN2M0AVMI15 supports XIP from external serial NOR flash via its dual QuadSPI interfaces, including SDR, DDR, and octal configurations. This capability is implemented in hardware and documented in Section 3.3.1 of the datasheet. The MK28FN2M0AVMI15 uses dedicated instruction fetch paths and cache coherency logic to ensure deterministic timing during XIP operation without CPU stalling.

What are the supported voltage domains for I/O pins on the MK28FN2M0AVMI15?

The MK28FN2M0AVMI15 defines four independent I/O voltage domains: VDD (1.71–3.6 V) for Ports A–D, VDDIO_E (1.71–3.6 V) for Port E (QuadSPI), VDDA (1.71–3.6 V) for analog modules, and VBAT (1.71–3.6 V) for RTC-related pins. Each domain has distinct electrical characteristics - for example, VIH_E is referenced to VDDIO_E, not VDD - and must be independently decoupled per the layout guidelines in the package drawing 98ASA00628D1.

How does the Power Management Controller (PMC) with Core Voltage Bypass function in the MK28FN2M0AVMI15?

The PMC in the MK28FN2M0AVMI15 provides a dedicated VDD_CORE bypass path that allows an external PMIC to directly regulate the core voltage, decoupling it from the main VDD rail. This enables dynamic voltage scaling, fine-grained power state transitions, and improved system efficiency - especially critical in battery-operated applications. The MK28FN2M0AVMI15's PMC registers expose status and control bits for monitoring and coordinating with the external PMIC, as detailed in Chapter 37 of the K28P210M150SF5 Reference Manual.

Is the MK28FN2M0AVMI15 pin-compatible with other Kinetis K28F variants?

Yes, the MK28FN2M0AVMI15 shares identical pinout and footprint with MK28FN2M0VMI15 (same 169 MAPBGA package), differing only in mask set revision (2N96T vs. 2N96T1). Both parts are electrically and mechanically interchangeable. However, MK28FN2M0CAU15R (210 WLCSP) is not pin-compatible due to different package type, ball count, and I/O mapping - requiring PCB redesign for substitution.
