The MCX C14x/24x/44x microcontrollers, featuring an Arm® Cortex®-M0+ core, offer a range of memory configurations, from 32KB to 256KB Flash and up to 32KB SRAM, with 16KB Boot ROM. These entry-level MCUs are optimized for cost-sensitive and battery-powered applications requiring low-power USB connectivity and segment LCD support. The FlexIO technology enables customization for various serial peripheral emulation needs. They feature optimized low-power modes, achieving efficiency down to 54uA/MHz in very low-power run mode and 1.96 uA in deep sleep mode with retained RAM and RTC. These devices are supported by the MCUXpresso Developer Experience to optimize, ease and help accelerate embedded system development.
