Product details
Overview
MCXC041VFG 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 - ideal for battery-powered smart power sockets and DC fan control.
For engineers reviewing the MCXC041VFG datasheet, MCXC041VFG pinout, MCXC041VFG application, or MCXC041VFG equivalent, key selection considerations include its 16-pin QFN package, USB-free segment LCD capability, 1.71–3.6 V supply range, -40 to 125°C junction temperature rating, and absence of integrated USB or LCD drivers in this variant.
Technical Context
The MCXC041VFG 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 6-bit DAC, while system-level features comprise low/high-frequency oscillators, internal reference clocks, and COP watchdog.
Memory architecture includes 32 KB on-chip Flash with error correction, 2 KB SRAM, and 8 KB Boot ROM containing a configurable bootloader. Power management supports multiple low-power modes: 2.2 μA static (full retention), 7.5 μs wake-up time, and deep-sleep mode down to 77 nA with RTC retention.

FAQ
Does MCXC041VFG support USB connectivity?
No, MCXC041VFG does not integrate a USB controller. Unlike MCXC24x/44x variants, this part lacks USB FS 2.0 hardware. MCXC041VFG relies on UART or LPUART for host communication. USB capability requires upgrading to MCXC242VFM or MCXC444VLH, which include dedicated USB PHY and transceivers.
What is the maximum operating frequency of MCXC041VFG?
The MCXC041VFG operates at a maximum core frequency of 48 MHz, sustained across its full 1.71–3.6 V supply range and -40 to 125°C junction temperature. This frequency is achieved using the internal high-frequency oscillator or optional external clock source, with no derating required under specified conditions.
Is MCXC041VFG pin-compatible with other MCX C-series MCUs?
No, MCXC041VFG is not pin-compatible with other MCX C-series parts due to its unique 16-pin QFN (VFG) package. MCXC041VFK uses a 24-pin QFN (VFK), and MCXC141VFM uses a 32-pin QFN (VFM). Pin counts, spacing, and signal assignments differ - board redesign is required for substitution.
Does MCXC041VFG include a segment LCD controller?
No, MCXC041VFG does not include a segment LCD controller. That feature is reserved for MCXC44x family members (e.g., MCXC444VLH). MCXC041VFG omits SLCD hardware entirely - confirmed by NXP's MCX C04x/C14x/24x/44x MCU Options table and block diagram documentation.
What debug interface does MCXC041VFG support?
MCXC041VFG supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins. It includes a Micro Trace Buffer for real-time instruction trace without halting execution. JTAG is not supported. Debugging is fully compatible with MCUXpresso IDE, IAR Embedded Workbench, and Keil MDK.
