Product details
Overview
MCXC141VFM from NXP is an Arm® Cortex®-M0+ microcontroller operating at up to 48 MHz, featuring 32 KB Flash, 8 KB SRAM, and 16 KB Boot ROM, with 28 GPIOs, USB FS 2.0 (crystal-less), segment LCD support (24×8 or 28×4), and ultra-low-power deep-sleep mode at 1.96 μA (RAM + RTC retained) - used in smart power sockets and battery-powered home security sensors.
For engineers reviewing the MCXC141VFM datasheet, MCXC141VFM pinout, MCXC141VFM application, or MCXC141VFM equivalent, key selection considerations include its 32-pin QFN package, crystal-free USB capability, segment LCD driver integration, and verified 1.71–3.6 V supply range with -40 to 125°C junction temperature rating.
Technical Context
The MCXC141VFM implements a static low-power architecture with multiple sleep modes: deep-sleep current of 1.96 μA (RTC + RAM retained), very low-power run mode at 54 μA/MHz, and wake-up time of 7.5 μs from full retention. It integrates FlexIO for customizable serial peripheral emulation and supports USB FS 2.0 without external crystal via internal oscillator calibration.
Its analog subsystem includes a 12-bit ADC, ACMP with 6-bit DAC, internal voltage reference, and low-leakage wake-up unit. System-level features comprise SWD debug interface, Micro Trace Buffer, COP software watchdog, and 80-bit unique chip ID embedded in ROM.

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, same 32QFN package and peripheral set | Better suited for applications requiring larger firmware (e.g., BLE stack + sensor fusion) | Select when firmware size exceeds 32 KB or additional RAM is needed for real-time buffering |
| Kinetis KL17Z128VLH4 | ARM Cortex-M0+, 128 KB Flash, 16 KB SRAM, 64LQFP only, no integrated segment LCD | Lacks native SLCD support; requires external driver for display; higher pin count limits miniaturization | Choose only if existing LQFP layout exists and SLCD is not required; otherwise, MCXC141VFM offers superior integration |
