FAQ

What is the maximum operating frequency of the MK24FN1M0VDC12 core?

The MK24FN1M0VDC12 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 4–32 MHz crystal or internal reference clocks. The device maintains full peripheral functionality and timing compliance at this speed across its specified voltage (1.71–3.6 V) and temperature (–40 to 105°C) ranges, as verified in NXP's K24P144M120SF5 datasheet Rev. 7.

Does the MK24FN1M0VDC12 support crystal-less USB operation?

Yes, the MK24FN1M0VDC12 supports crystal-less USB full-speed and low-speed operation via its integrated USB OTG 2.0 controller. This capability eliminates the need for an external 48 MHz crystal or oscillator, reducing BOM cost and PCB area. The internal 48 MHz IRC (IRC48M) provides the required clock source, and the USB PHY includes built-in trimming to maintain ±0.25% accuracy over voltage and temperature - confirmed in Section 3.8.1 of the K24F datasheet.

How many GPIO pins does the MK24FN1M0VDC12 provide in its 100-pin LQFP package?

The MK24FN1M0VDC12 in the 100-pin LQFP package provides 83 general-purpose I/O pins, as specified in NXP's Ordering Information table (Rev. 7, p. 2). These GPIOs support multiple peripheral functions via pin multiplexing, including UART, I²C, SPI, CAN, ADC inputs, and PWM outputs. All 83 pins are individually configurable for pull-up/pull-down, drive strength, and interrupt triggering - enabling flexible hardware design without external logic.

What hardware security features are integrated into the MK24FN1M0VDC12?

The MK24FN1M0VDC12 integrates dedicated hardware security modules including AES-128/256, DES/3DES, SHA-1/SHA-256 cryptographic accelerators, a true random number generator (TRNG), and CRC-32 computation engine. It also includes a 128-bit unique identification number per chip and memory protection unit (MPU) with multi-master enforcement. These features are documented in Sections 3.5 and 7.1 of the K24F datasheet and enable secure boot, encrypted firmware updates, and TLS offload without software-only overhead.

What is the lowest achievable power consumption mode for the MK24FN1M0VDC12?

The MK24FN1M0VDC12 achieves its lowest power consumption in Very-Low-Leakage Stop Mode 0 (VLLS0) with POR detect circuit disabled, drawing just 339 nA at –40 to 25°C and 3.0 V supply (Table 6, K24F datasheet Rev. 7). In this mode, the core, peripherals, and most clocks are halted while retaining full register and RAM contents, and wakeup can occur within 5 μs via RTC alarm or GPIO event - making it ideal for battery-powered applications requiring years of operation on a single coin cell.
