Product details
Overview
MCXC144VFT from NXP is an Arm® Cortex®-M0+ microcontroller operating at up to 48 MHz, featuring 256 KB Flash, 32 KB SRAM, 16 KB Boot ROM, and 40 GPIOs in a 48-pin QFN package. It integrates USB Full-Speed 2.0 device interface without external crystal, FlexIO for custom serial peripheral emulation, and supports segment LCD up to 24×8 segments - deployed in smart power sockets and battery-powered home security sensors.
For engineers reviewing the MCXC144VFT datasheet, MCXC144VFT pinout, MCXC144VFT application, or MCXC144VFT equivalent, key selection criteria include its 54 μA/MHz very low-power run mode, 1.96 μA deep sleep (RAM + RTC retained), 1.71–3.6 V supply range, -40 to 125°C junction temperature rating, and integrated boot loader with 80-bit unique chip ID.
Technical Context
The MCXC144VFT implements an Arm Cortex-M0+ core with Micro Trace Buffer and SWD debug interface, paired with a low-leakage wake-up unit and configurable clock system including internal high/low-frequency oscillators and reference clocks. Its memory subsystem includes 256 KB flash with advanced security, 32 KB SRAM, and 16 KB boot ROM containing a field-upgradable bootloader.
Peripherals include one 12-bit ADC, ACMP with 6-bit DAC, two I²C, two SPI, one UART, two LPUART, six-channel + dual two-channel timer/PWM modules, real-time clock, and FlexIO supporting UART/I²C/SPI emulation. 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 |
|---|---|---|---|
| MCXC244VFT | Same 48QFN package, adds USB FS 2.0 PHY and SLCD support - 256 KB Flash, 32 KB SRAM identical | Required where USB device functionality (e.g., HID keyboard/mouse emulation) or segment LCD is mandatory | Select MCXC244VFT when USB connectivity or on-device display is essential; MCXC144VFT suffices for headless, non-USB designs |
| KL17Z128VLH4 | Legacy Kinetis L1 family; 128 KB Flash, 16 KB SRAM, 64LQFP package - no USB, no SLCD, lower integration | Suitable for cost-sensitive, non-USB, non-LCD applications requiring long-term availability over new design-in | Choose KL17Z128VLH4 only for legacy migration or where NXP's long-term supply commitment outweighs feature gap |
Compared with MCXC244VFT, MCXC144VFT omits USB and SLCD hardware - reducing die size and dynamic power, making it optimal for headless, ultra-low-power sensor nodes. Against KL17Z128VLH4, MCXC144VFT delivers 2× Flash/SRAM, modern low-power architecture, and FlexIO flexibility - justifying migration for new designs.

FAQ
Does MCXC144VFT support USB device functionality?
No, MCXC144VFT does not integrate a USB physical layer. Unlike MCXC244VFT or MCXC444VLH, it lacks the USB FS 2.0 transceiver and associated registers. The MCXC144VFT datasheet confirms USB is not implemented in this variant. For USB-enabled designs, consider MCXC244VFT or MCXC444VLH instead. MCXC144VFT retains all other peripherals - including FlexIO, SLCD, ADC, and timers - making it ideal for non-USB, ultra-low-power applications.
What is the maximum segment LCD configuration supported by MCXC144VFT?
The MCXC144VFT supports up to 24×8 or 28×4 segment LCD configurations, as confirmed in the MCX C Series Fact Sheet and MCXCFS REV 0 documentation. This capability is enabled by dedicated SLCD peripheral hardware with built-in bias generation and multiplexing control. No external LCD driver IC is required. The 48-pin QFN package provides sufficient COM/SEG pins to drive full 192-segment displays, commonly used in smart power sockets and thermostats.
Is MCXC144VFT pin-compatible with other MCX C14x family members in 48QFN?
Yes, MCXC144VFT shares the same 48-pin QFN footprint and pinout with MCXC143VFT and MCXC244VFT, as verified in the "MCX C04x/C14x/24x/44x MCU Options" table. All three use identical mechanical dimensions, pad layout, and thermal pad configuration. However, signal mapping differs where peripherals vary - e.g., USB pins on MCXC244VFT are NC on MCXC144VFT. PCB reuse is feasible only if unused pins are left unconnected or repurposed safely.
What debug interface does MCXC144VFT provide?
MCXC144VFT provides Serial Wire Debug (SWD) via dedicated SWD_DIO and SWD_CLK pins, fully compliant with ARM CoreSight standards. It supports full-speed programming, real-time variable inspection, and instruction trace via the integrated Micro Trace Buffer. No JTAG header is required. Debugging is supported natively in MCUXpresso IDE, Keil MDK, and IAR Embedded Workbench - all validated with MCXC144VFT reference designs and FRDM evaluation boards.
Does MCXC144VFT include a hardware cryptographic accelerator?
No, MCXC144VFT does not include a dedicated hardware cryptographic accelerator such as AES or SHA engines. Security relies on software-implemented algorithms and flash-based protection features like region locking, secure boot, and debug disable. The MCX C Series prioritizes low-cost, low-power operation over cryptographic acceleration; for hardware crypto, consider NXP's LPC55Sxx or i.MX RT1010 families. MCXC144VFT's advanced flash security remains effective for firmware IP protection and anti-cloning.
