FAQ

What is the maximum operating frequency and core architecture of the MK64FN1M0VLQ12?

The MK64FN1M0VLQ12 features an ARM Cortex-M4 core with integrated floating-point unit (FPU) and digital signal processing (DSP) extensions, rated for operation up to 120 MHz. This frequency is achievable under specified voltage (1.71–3.6 V) and temperature (-40°C to 105°C) conditions, with performance validated using the PEE clock mode and MCG PLL configuration per the K64 reference manual. The MK64FN1M0VLQ12 delivers deterministic real-time execution essential for industrial control loops.

Does the MK64FN1M0VLQ12 support crystal-less USB operation?

Yes, the MK64FN1M0VLQ12 supports crystal-less USB full-speed and low-speed device operation using its internal 48 MHz IRC (IRC48M) clock source. This eliminates the need for an external 48 MHz crystal, reducing BOM cost and PCB area. The IRC48M meets USB timing tolerance (±0.25%) across voltage and temperature ranges, and is enabled via USBCTRL register settings. The MK64FN1M0VLQ12 retains full USB OTG functionality including suspend/resume and charger detection.

What Ethernet interface options does the MK64FN1M0VLQ12 provide?

The MK64FN1M0VLQ12 integrates a 10/100 Mbit/s Ethernet MAC with both MII and RMII physical layer interfaces. It supports IEEE 1588-2008 precision time protocol via dedicated timestamp registers and hardware capture logic. The MAC includes configurable FIFOs, checksum offload (IP/TCP/UDP), and multicast filtering. No external PHY is required for RMII - only a 50 MHz reference clock and magnetics are needed. The MK64FN1M0VLQ12 does not include a PHY; external PHY selection must match RMII/MII signaling and timing specs.

What low-power modes are available on the MK64FN1M0VLQ12, and what is the lowest current draw?

The MK64FN1M0VLQ12 supports seven low-power modes, including VLLS0 (Very-Low-Leakage Stop Mode 0) with full register and RAM retention. In VLLS0 with POR detect disabled, typical current consumption is 339 nA at 3.0 V and 25°C - the lowest among Kinetis K64 variants. Wake-up occurs in ≤5 μs via GPIO, RTC alarm, or LLWU sources. All modes retain critical state, and VLLS0 is qualified for operation across the full -40°C to 105°C range. The MK64FN1M0VLQ12 achieves this via optimized power gating and leakage suppression circuits.

Does the MK64FN1M0VLQ12 include hardware cryptographic acceleration?

Yes, the MK64FN1M0VLQ12 includes dedicated hardware modules for AES-128/256, DES/3DES, SHA-1/256, MD5, and CRC-32, plus a true random number generator (TRNG). These accelerators operate independently of the CPU core, enabling concurrent encryption/decryption and hash computation without impacting real-time task scheduling. Key derivation, TLS handshake, and secure boot verification execute in microseconds rather than milliseconds. The MK64FN1M0VLQ12 uses these blocks to meet IEC 62443-3-3 SL2 security requirements out-of-the-box.
