Product details
Overview
MCXC041VFK from NXP is an entry-level Arm® Cortex®-M0+ microcontroller operating at up to 48 MHz, featuring 32 KB Flash, 2 KB SRAM, and 8 KB Boot ROM. It integrates a 12-bit ADC, comparator, multiple timer/PWM modules, and supports low-power operation down to 2.2 μA static current with 7.5 μs wake-up time - deployed in smart power sockets and DC fan control.
For engineers reviewing the MCXC041VFK datasheet, MCXC041VFK pinout, MCXC041VFK application, or MCXC041VFK equivalent, key selection criteria include QFN24 package compatibility, USB-free segment LCD capability, 1.71–3.6 V supply range, -40 to 125°C junction temperature rating, and FlexIO peripheral support for custom serial emulation.
Technical Context
The MCXC041VFK implements an Arm Cortex-M0+ core with micro trace buffer and NVIC, paired with a low-leakage wake-up unit and DMA controller. Its analog subsystem includes a 12-bit ADC and ACMP with integrated 6-bit DAC and internal voltage reference.
System-level features include dual LPUARTs, two I²C and two SPI interfaces, one UART, and clocking via low/high-frequency oscillators plus internal reference clocks - all operating within 1.71–3.6 V supply and qualified for -40 to 125°C Tj.

FAQ
What is the maximum operating frequency of the MCXC041VFK?
The MCXC041VFK operates at a maximum core frequency of 48 MHz using its Arm Cortex-M0+ processor. This speed is fully supported across the entire specified voltage range (1.71–3.6 V) and temperature range (-40 to 125°C). The MCXC041VFK achieves deterministic real-time response in fan control and socket switching applications without requiring external PLL circuitry.
Does the MCXC041VFK support USB connectivity?
No, the MCXC041VFK does not integrate USB functionality. USB FS 2.0 is only available in the MCXC24x/44x families (e.g., MCXC242VFM). The MCXC041VFK retains all other core peripherals - including FlexIO, ADC, timers, and LPUARTs - making it ideal for non-USB applications like standalone smart sockets and fan controllers where USB is unnecessary.
What package type and dimensions does the MCXC041VFK use?
The MCXC041VFK uses a 24-pin QFN package measuring 4 × 4 mm with 0.5 mm pin pitch and wettable flanks. This package is RoHS-compliant and optimized for reflow soldering and automated optical inspection. Its thermal pad improves heat dissipation in enclosed smart socket housings, and the pin count matches the 22 GPIOs plus power/ground/debug signals defined in the MCXC041VFK datasheet.
Can the MCXC041VFK drive a segment LCD display?
No, the MCXC041VFK lacks integrated segment LCD (SLCD) controller hardware. SLCD support begins with the MCXC44x family (e.g., MCXC444VLH). The MCXC041VFK retains full compatibility with external LCD drivers or discrete LED arrays via its 22 GPIOs and PWM modules - enabling status indication and basic HMI in smart power sockets without LCD overhead.
What debug interface does the MCXC041VFK provide?
The MCXC041VFK includes a standard Serial Wire Debug (SWD) interface with SWD_DIO and SWD_CLK pins, supporting full JTAG/SWD protocol for programming and real-time debugging. It also integrates a Micro Trace Buffer for instruction trace capture. This debug capability is accessible directly through the 24-pin QFN footprint - no auxiliary debug header required - simplifying test fixture design for MCXC041VFK-based production boards.
