Product details
Overview
MCXC444VMP from NXP is an Arm® Cortex®-M0+ microcontroller operating at up to 48 MHz, featuring 256 KB Flash, 32 KB SRAM, USB Full-Speed 2.0 device interface without external crystal, segment LCD controller (24×8 or 28×4), and FlexIO for custom serial peripheral emulation - deployed in smart power sockets and battery-powered home security sensors.
For engineers reviewing the MCXC444VMP datasheet, MCXC444VMP pinout, MCXC444VMP application, or MCXC444VMP equivalent, key selection considerations include its 64-ball BGA package, deep-sleep current of 1.96 µA with RTC+RAM retention, 1.71–3.6 V supply range, -40 to 125°C junction temperature rating, and integrated boot ROM with secure bootloader.
Technical Context
The MCXC444VMP implements a low-power Arm Cortex-M0+ core with micro trace buffer and SWD debug interface, paired with dual LPUARTs, two I²C, two SPI, one UART, and FlexIO for protocol flexibility. Its clock system integrates low/high-frequency oscillators and internal reference clocks.
Power management includes multiple low-power modes: very low-power run mode (54 µA/MHz), deep sleep (1.96 µA with RAM+RTC retained), and static mode down to 77 nA. Wake-up latency is 7.5 µs with full register retention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Kinetis KL27Z128VLH4 | 32-bit ARM Cortex-M0+, 48 MHz, 128 KB Flash, 16 KB SRAM, USB FS, no segment LCD controller | Lacks native SLCD support; requires external driver or GPIO bit-banging for display | Choose when USB + low power are critical but display is LED-only or OLED-based |
| RA2A1 R7FA2A1AB3CFM | Arm Cortex-M23, 48 MHz, 256 KB Flash, 32 KB SRAM, USB FS, segment LCD (24×4), no FlexIO | Offers TrustZone security extension but lacks FlexIO; SLCD supports fewer segments than MCXC444VMP | Prefer when hardware-enforced security isolation is mandatory and display complexity is lower |
Compared with KL27Z128VLH4 and RA2A1 R7FA2A1AB3CFM, the MCXC444VMP uniquely combines crystal-less USB, 24×8 segment LCD capability, and FlexIO in a single 64BGA package - making it optimal for cost-sensitive, display-equipped, battery-aware edge nodes where peripheral flexibility and BOM simplification are design priorities.

FAQ
Does MCXC444VMP require an external crystal for USB operation?
No, MCXC444VMP features an internal USB PLL with factory-trimmed oscillator, enabling full-speed USB 2.0 device operation without any external crystal or load capacitors. This eliminates three BOM items and simplifies PCB layout. The internal oscillator meets USB suspend/resume timing requirements per MCXC444VMP's electrical specifications and has been validated across temperature and voltage ranges.
What segment LCD configurations does MCXC444VMP support?
MCXC444VMP supports two segment LCD configurations: 24 segments × 8 commons or 28 segments × 4 commons. It drives these directly using integrated SLCD peripheral with software-configurable bias and frame frequency. No external LCD driver IC is needed, reducing system cost and board area. The configuration is selected at runtime via SLCD control registers in the MCXC444VMP memory map.
What is the lowest achievable current consumption in deep-sleep mode for MCXC444VMP?
The lowest verified deep-sleep current for MCXC444VMP is 1.96 µA with RTC and SRAM fully retained, measured at 3.0 V and 25°C per NXP's MCXCFS REV 0 fact sheet. This value assumes all unused peripherals disabled, GPIOs configured as high-impedance inputs with pull-downs disabled, and VDD/VSS pins properly decoupled. Real-world designs achieve <2.1 µA with careful layout and power sequencing.
Is MCXC444VMP pin-compatible with other MCX C44x variants like MCXC443VMP?
Yes, MCXC444VMP and MCXC443VMP share identical 64-ball BGA package footprints, pin assignments, and power/ground ball layout. Both support the same USB, SLCD, FlexIO, and peripheral pin mappings. However, MCXC444VMP includes 256 KB Flash versus 128 KB in MCXC443VMP - this difference does not affect pin compatibility but impacts firmware partitioning and bootloader placement.
Which development boards are officially supported for MCXC444VMP evaluation?
The FRDM-MCXC444 is the official NXP development board for MCXC444VMP, featuring the exact 64LQFP variant (MCXC444VLH) pre-soldered with USB debug interface, onboard RGB LED, push buttons, and Arduino-compatible headers. While MCXC444VMP itself is in 64BGA, the FRDM-MCXC444 provides accessible signals and example projects targeting the full MCX C44x feature set, including USB CDC, SLCD simulation, and FlexIO UART emulation.
