FAQ

What is the maximum operating frequency of the MK64FN1M0VLL12 core?

The MK64FN1M0VLL12 features an ARM Cortex-M4 core rated for up to 120 MHz operation under specified voltage (1.71–3.6 V) and temperature (–40 to 105°C) conditions. This frequency is achievable using the Phase-Locked Loop (PLL) with external 3–32 MHz crystal input or internal 48 MHz IRC source, as documented in Section 2.3.1 of the K64P144M120SF5 datasheet. The MK64FN1M0VLL12 maintains full peripheral functionality including Ethernet and USB at this speed.

Does the MK64FN1M0VLL12 support crystal-less USB operation?

Yes, the MK64FN1M0VLL12 supports crystal-less USB full-speed and low-speed operation using its internal 48 MHz IRC oscillator, eliminating the need for an external 48 MHz crystal. This capability is enabled via the USBOTGCTL register and requires calibration of the IRC48M using the USB trim register (USBTRIM) - detailed in Section 3.8.2 of the K64F datasheet. The MK64FN1M0VLL12 achieves ±0.25% accuracy in crystal-less mode across temperature.

What Ethernet interface modes does the MK64FN1M0VLL12 support?

The MK64FN1M0VLL12 integrates a 10/100 Mbit/s Ethernet MAC supporting both MII and RMII physical layer interfaces. RMII mode uses 9 pins (including ENET0_RXD0/1, ENET0_TXD0/1, ENET0_TX_EN, ENET0_RX_ER, ENET0_CRS_DV, ENET0_REF_CLK) and requires an external PHY; MII mode uses 16 pins and supports direct connection to legacy PHYs. Both modes are fully supported in the K64 SDK and validated in the FRDM-K64F reference design.

How much SRAM is available on the MK64FN1M0VLL12 for application use?

The MK64FN1M0VLL12 provides 256 KB of on-chip SRAM, all accessible to the application without bank switching or remapping. This includes 240 KB general-purpose SRAM plus 16 KB reserved for system use (stack, heap, peripheral buffers). The MK64FN1M0VLL12 supports configurable memory protection unit (MPU) regions to isolate critical RTOS tasks and prevent buffer overflow corruption.

What low-power modes are available on the MK64FN1M0VLL12?

The MK64FN1M0VLL12 supports seven low-power modes: RUN, WAIT, VLPR, VLPW, STOP, VLPS, and LLS - plus four Very Low-Leakage Stop (VLLS) variants (VLLS0–VLLS3). Minimum current is 339 nA in VLLS0 with POR circuit disabled and RTC disabled, verified per Table 6 of the K64F datasheet. Wake-up latency ranges from 4.5 μs (VLPS→RUN) to 156 μs (VLLS0→RUN), enabling responsive event-driven operation.
