Product details
Overview
MCXC141VLH from NXP is an entry-level Arm® Cortex®-M0+ microcontroller operating at up to 48 MHz, featuring 32 KB Flash, 8 KB SRAM, 16 KB Boot ROM, and 54 GPIOs in a 64-pin LQFP package. It supports low-power operation (54 μA/MHz run mode, 1.96 μA deep sleep), USB Full-Speed device interface without external crystal, and segment LCD driving capability for HMI applications.
For engineers reviewing the MCXC141VLH datasheet, MCXC141VLH pinout, MCXC141VLH application, or MCXC141VLH equivalent, key selection considerations include its 64LQFP package, USB FS 2.0 device support without external crystal, segment LCD driver (24×8 or 28×4), 1.71–3.6 V supply range, and -40 to 125°C junction temperature rating.
Technical Context
The MCXC141VLH implements an Arm Cortex-M0+ core with Micro Trace Buffer and SWD debug interface, paired with a low-leakage wake-up unit and flexible clock system including internal high/low-frequency oscillators. It integrates a 12-bit ADC, ACMP with 6-bit DAC, and multiple timer/PWM modules (1×6-channel + 2×2-channel).
Its memory subsystem includes 32 KB on-chip Flash, 8 KB SRAM, and 16 KB Boot ROM containing a configurable bootloader. FlexIO enables emulation of custom serial protocols, while USB FS 2.0 operates without external crystal via internal oscillator calibration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCXC142VFM | 64 KB Flash, 16 KB SRAM, 24-pin QFN - higher memory, smaller package, no USB | Suitable for compact, memory-constrained designs without USB or LCD needs | Select when footprint reduction and extra code space outweigh USB/LCD requirements |
| MCXC242VLH | 64 KB Flash, 16 KB SRAM, USB FS enabled, same 64LQFP package - adds USB functionality | Required where host-side USB enumeration or device firmware upgrade over USB is mandatory | Choose when crystal-less USB device capability is essential and 32 KB Flash is insufficient |
Compared with MCXC141VLH, MCXC142VFM trades USB and LCD support for higher memory density in QFN, while MCXC242VLH retains identical packaging and adds USB functionality at the cost of reduced Flash headroom for non-USB applications.

FAQ
Does MCXC141VLH support USB device functionality without an external crystal?
Yes, MCXC141VLH integrates a factory-calibrated internal 48 MHz oscillator that meets USB Full-Speed timing requirements, eliminating the need for an external 12 MHz crystal and associated load capacitors. This feature is confirmed in the MCX C Series Fact Sheet (Document Number: MCXCFS REV 0) and applies specifically to MCXC141VLH's USB FS 2.0 device interface.
What segment LCD configurations does MCXC141VLH support?
MCXC141VLH supports up to 24×8 or 28×4 segment LCD configurations using its integrated SLCD peripheral. These modes are hardware-defined and require no external driver IC. The exact mapping depends on pin assignment in the 64LQFP package and is detailed in the MCX C Series Reference Manual section on Segment LCD Controller.
Is MCXC141VLH pin-compatible with other MCX C Series devices in 64LQFP?
No, MCXC141VLH is not fully pin-compatible with other 64LQFP MCX C Series variants such as MCXC242VLH or MCXC444VLH. While all share the same package outline, pin functions differ significantly - especially for USB, LCD, and peripheral signals - requiring PCB redesign for substitution.
What debug interface does MCXC141VLH provide?
MCXC141VLH includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, supporting full JTAG-style debugging, flash programming, and real-time trace via the Micro Trace Buffer. This interface is accessible through standard SWD connectors and supported by MCUXpresso IDE, IAR Embedded Workbench, and Keil MDK.
What is the minimum deep-sleep current for MCXC141VLH with RTC and RAM retention?
The minimum deep-sleep current for MCXC141VLH with RTC and RAM retained is 1.96 μA, measured under specified conditions (VDD = 3.0 V, Tj = 25°C). This value is documented in the MCX C Series Electrical Characteristics table and reflects the lowest achievable static power state for battery-backed operation.
