Ultra-Low-Power, Highly Integrated MCU
The K32 L2 MCU family’s low-leakage architecture, combined with its power-optimized peripherals and security features (such as cryptographic acceleration technology, 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 with options scaling from 64 KB to 512 KB Flash and from 32 kB to 128 kB SRAM, the K32 L2 family offers a wide range of memory resources to fit different application tasks within a small-form factor, low power, and highly integrated design.
