NXP Semiconductors MK24FN1M0VLL12R

Overview

MK24FN1M0VLL12 from NXP Semiconductors is a 120 MHz ARM® Cortex®-M4 microcontroller with FPU, 1 MB flash, 256 KB SRAM, and USB LS/FS OTG 2.0 with crystal-less operation. It delivers 250 μA/MHz run power, 5.8 μA static current with full state retention, and operates from –40 to 105°C at 1.71–3.6 V. It is used in industrial USB-connected edge nodes requiring low-power real-time control and secure firmware updates.

For engineers reviewing the MK24FN1M0VLL12 datasheet, MK24FN1M0VLL12 pinout, MK24FN1M0VLL12 application, or MK24FN1M0VLL12 equivalent, key selection criteria include its 144-pin LQFP package, dual 16-bit ADCs, hardware AES/SHA-256 encryption, CAN 2.0B interface, and verified 120 MHz deterministic execution under RTOS.

Technical Context

The MK24FN1M0VLL12 implements a tightly coupled ARM Cortex-M4 core with DSP extensions and single-precision floating-point unit, supported by a multi-layer AHB bus matrix and 16-channel DMA controller. Its memory subsystem includes 1 MB on-chip flash with 64-bit prefetch buffer and 256 KB SRAM split across multiple banks for concurrent access.

Low-power operation is enabled by six distinct power modes (RUN, VLPR, STOP, VLPS, LLS, VLLS), with VLLS0 consuming as low as 339 nA and sub-5 μs wakeup. Clock management integrates PLL, FLL, IRC48M, and 3–32 MHz external crystal support, while security relies on dedicated hardware CRC, RNG, and cryptographic accelerators for DES/3DES/AES/SHA-1/SHA-256.

FAQ

What is the maximum operating frequency and core type of the MK24FN1M0VLL12?

The MK24FN1M0VLL12 features an ARM Cortex-M4 core with integrated floating-point unit, rated for continuous operation at 120 MHz across its full temperature range (–40 to 105°C). This frequency is achievable using the on-chip PLL with external 4–32 MHz crystal or internal IRC sources, and is validated under worst-case voltage (1.71 V) and temperature conditions per NXP's K24F datasheet Rev. 7.

Does the MK24FN1M0VLL12 support crystal-less USB device operation?

Yes, the MK24FN1M0VLL12 supports crystal-less USB full-speed device mode using its internal 48 MHz IRC (IRC48M) calibrated to ±0.25% accuracy. This eliminates the need for an external 12 MHz crystal in USB device applications, reducing BOM cost and PCB footprint - confirmed in Section 3.8.1 of the K24F datasheet and validated in NXP's AN4959 application note.

How much SRAM and flash memory does the MK24FN1M0VLL12 include?

The MK24FN1M0VLL12 integrates 1 MB of on-chip program flash memory and 256 KB of general-purpose SRAM. The flash supports 100,000 erase/write cycles and includes error correction circuitry; the SRAM is organized in multiple banks to enable concurrent CPU and DMA access - both values are explicitly listed in the Ordering Information table of the K24F datasheet Rev. 7.

What low-power modes are available on the MK24FN1M0VLL12, and what is the lowest current draw?

The MK24FN1M0VLL12 offers six low-power modes: RUN, VLPR, STOP, VLPS, LLS, and VLLS. Its lowest active-retention mode is VLLS0, drawing as little as 339 nA at 3.0 V and –40 to 25°C with POR detect disabled - measured and specified in Table 6 of the K24F datasheet Rev. 7, enabling decade-long battery operation in wake-on-event sensor applications.

Which hardware security features are integrated into the MK24FN1M0VLL12?

The MK24FN1M0VLL12 includes a hardware CRC module, true random number generator (TRNG), and cryptographic accelerator supporting DES, 3DES, AES-128/192/256, MD5, SHA-1, and SHA-256. These are physically isolated peripherals with dedicated clock domains and memory-mapped registers - all documented in Sections 3.5 and 3.6 of the K24F datasheet Rev. 7 and validated in NXP's K24 Security Reference Manual.
