NXP Semiconductors K32 L2 MCU family low-power MCUs

The K32 L2 MCU family's low-leakage architecture, combined with its power-optimized peripherals and security features (cryptographic acceleration, cyclic redundancy check, and a true random number generator), make it ideal for consumer, industrial and IoT applications requiring a low-priced, power-efficient option with longer battery life.

This family includes a low power Arm® Cortex®-M0+ core and scaling from 64KB to 512KB Flash and 32KB to 128KB SRAM, offering a wide range of memory resources to fit different application within a small-form-factor, low power, and highly integrated design.
