K32L2A31VLH1A数据手册恩XP中文资料规格书

描述 Description

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 atrue 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 scalingfrom 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, andhighly integrated design.
