Technical Context

The MK24FN1M0VDC12R implements a dual-oscillator clock system with 3–32 MHz external crystal and 48 MHz IRC48M internal reference, supporting PEE, FEI, and BLPE modes for dynamic frequency scaling between 120 MHz (full performance) and 4 MHz (VLPR). Its MCG module enables seamless transitions across RUN, VLPS, STOP, and VLLSx power states.

It integrates two 16-bit SAR ADCs (1.25 MSPS max), two 12-bit DACs, three analog comparators, and a hardware encryption engine supporting AES-128/256, SHA-1/256, and DES/3DES-enabling secure firmware updates and sensor data confidentiality in field-deployed edge nodes.

FAQ

What is the maximum operating frequency of the MK24FN1M0VDC12R core?

The MK24FN1M0VDC12R features an ARM Cortex-M4 core with floating-point unit rated for up to 120 MHz operation. This frequency is achievable using the Phase-Locked Loop (PLL) with a 3–32 MHz external crystal or the 48 MHz IRC48M internal reference. The core maintains full functionality-including FPU and DSP instructions-at this speed, enabling real-time signal processing in applications such as motor control and audio preprocessing. MK24FN1M0VDC12R supports dynamic clock scaling down to 4 MHz in Very-Low-Power Run mode.

Does the MK24FN1M0VDC12R support crystal-less USB device operation?

Yes, the MK24FN1M0VDC12R supports crystal-less USB Full-Speed device operation using its internal 48 MHz IRC oscillator, eliminating the need for an external 48 MHz crystal. This capability is enabled via the USBOTG controller's built-in clock recovery circuitry and is documented in Section 3.8.1 of the K24F Data Sheet. MK24FN1M0VDC12R retains full USB 2.0 LS/FS OTG compliance-including suspend/resume and remote wakeup-in this mode, reducing BOM cost and PCB area.

What low-power modes are available on the MK24FN1M0VDC12R and their typical current draw?

The MK24FN1M0VDC12R supports six low-power modes: RUN, WAIT, VLPR, VLPS, STOP, and VLLSx (0–3). At 3.0 V and 25°C, key values include 1.0 mA in VLPR (all clocks disabled), 0.678 mA in VLPW, 0.49 mA in STOP, 5.8 μA in LLS (full RAM retention), and 339 nA in VLLS0 with POR detect disabled. These figures are measured per Table 6 in the K24F Data Sheet Rev. 7. MK24FN1M0VDC12R achieves sub-μA retention in VLLS0 by gating all clocks except the 32 kHz RTC source and disabling the POR circuit.

How many GPIO pins does the MK24FN1M0VDC12R provide in its 100-pin LQFP package?

The MK24FN1M0VDC12R in the 100-pin LQFP package provides 83 general-purpose I/O pins, as confirmed in the Ordering Information table of the K24F Data Sheet Rev. 7. These GPIOs are distributed across ports A–E and support multiple peripheral functions including UART, SPI, I²C, CAN, USB, ADC, DAC, and FlexTimer channels. Each pin is individually configurable for pull-up/pull-down (20–50 kΩ), slew rate, and digital filter-critical for robust operation in electrically noisy industrial environments. MK24FN1M0VDC12R reserves remaining pins for power, ground, reset, and clock functions.

What cryptographic algorithms are supported in hardware by the MK24FN1M0VDC12R?

The MK24FN1M0VDC12R integrates a dedicated hardware encryption module supporting DES, 3DES, AES (128/192/256-bit), MD5, SHA-1, and SHA-256 algorithms. These accelerators operate independently of the CPU core, enabling high-throughput encryption/decryption and hash generation without impacting real-time task scheduling. The module is accessible via the Cryptographic Services Engine (CSEc) peripheral and is validated per NXP's K24F Security Reference Manual. MK24FN1M0VDC12R also includes a hardware random number generator compliant with NIST SP800-90B for entropy seeding.
