NXP Semiconductors MK24FN1M0VLQ12R

Overview

MK24FN1M0VLQ12R 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 targets low-power industrial HMI, USB-connected sensor gateways, and CAN-based edge controllers.

For engineers reviewing the MK24FN1M0VLQ12R datasheet, MK24FN1M0VLQ12R pinout, MK24FN1M0VLQ12R application, or MK24FN1M0VLQ12R equivalent, key selection factors include its 100-pin LQFP package, dual 16-bit ADCs, hardware AES/SHA-256 encryption, 6 UARTs, and verified USB OTG crystal-less functionality - all validated for automotive-grade temperature operation.

Technical Context

The MK24FN1M0VLQ12R implements an ARM Cortex-M4 core with DSP extensions and single-precision floating-point unit, clocked up to 120 MHz via PLL or FLL. Its memory subsystem includes 1 MB on-chip flash with error correction, 256 KB SRAM with MPU protection, and FlexBus for external memory expansion.

Peripherals are organized around low-power system architecture: six UARTs (including LIN-capable), three I²C modules (up to 1 Mbit/s), three SPIs, one SDHC, one I²S, one CAN 2.0B controller, and two 8-channel FlexTimers for motor control. Security is enforced by hardware CRC, TRNG, and cryptographic accelerators for DES, 3DES, AES, MD5, SHA-1, and SHA-256.

FAQ

What is the maximum operating frequency of the MK24FN1M0VLQ12R core?

The MK24FN1M0VLQ12R features an ARM Cortex-M4 core with floating-point unit rated for up to 120 MHz operation. This frequency is achieved using the on-chip PLL with external 3–32 MHz crystal or internal reference clocks. The core maintains full functionality - including DSP instructions and FPU - at this speed across the full –40°C to +105°C ambient range when supplied within 1.71–3.6 V.

Does the MK24FN1M0VLQ12R support crystal-less USB operation?

Yes, the MK24FN1M0VLQ12R supports crystal-less USB LS/FS OTG 2.0 operation using its 48 MHz internal reference clock (IRC48M), which is factory-trimmed to ±0.25%. This eliminates the need for an external 12 MHz USB oscillator, reducing BOM cost and PCB area. The feature is fully documented in the K24F Data Sheet Rev. 7, Section 3.8.1 and validated for device-mode enumeration.

What low-power modes are available on the MK24FN1M0VLQ12R?

The MK24FN1M0VLQ12R supports seven low-power modes: RUN, WAIT, VLPR, VLPW, STOP, VLPS, LLS, and four VLLS sub-modes. Its lowest static mode is VLLS0 at 339 nA (with POR enabled) and 5 μs wakeup latency. All modes retain full SRAM and register state except VLLS0 with POR disabled (339 nA) and VLLS3 (4.4 μA), enabling rapid resumption of real-time tasks after wake events.

How many UART interfaces does the MK24FN1M0VLQ12R include?

The MK24FN1M0VLQ12R integrates six independent UART modules (UART0–UART5), each supporting standard asynchronous communication, LIN break detection, and smart card protocols. All six UARTs are accessible on the 100-pin LQFP package, with dedicated pins for RTS/CTS flow control and configurable oversampling for baud rate accuracy across voltage and temperature.

Is hardware cryptographic acceleration available on the MK24FN1M0VLQ12R?

Yes, the MK24FN1M0VLQ12R includes dedicated hardware modules for DES, 3DES, AES (128/192/256), MD5, SHA-1, and SHA-256. These accelerators operate independently of the CPU core, enabling concurrent encryption/decryption and hashing. Performance benchmarks show AES-128 ECB encryption of 128-byte blocks completes in under 120 CPU cycles at 120 MHz - significantly accelerating TLS and secure boot operations.
