K32L2B31VMP0A

K32L2B31VMP0A Description

The low-leakage architecture, power-optimized peripherals, and security features (like cryptographic acceleration technology, cyclic redundancy check, and a true random number generator) of the K32L2B31VMP0A MCU family make it the perfect choice for the consumer, industrial, and IoT applications needing a low-cost, power-efficient option with longer battery life.

The low power Arm? Cortex?-M0+ processor in this series is perfect for applications that need to combine reduced cost and power with longer battery life. The K32 L2 family offers a wide range of memory resources to match varied application workloads inside a small-form-factor, low power, and highly integrated design, with options scaling from 64 KB to 512 KB Flash and from 32 kB to 128 kB SRAM.

The extension of the K32 L series further exemplifies NXP's focus on safe and power-efficient MCUs for the newest applications that are power-conscious and leakage-free.
