K32L2A31VLH1A

K32L2A31VLH1A is a K32 L2A, 72MHz Cortex-M0+ based microcontroller. It supports ultra-low-power Arm based microcontroller with crystalless USB feature, large flash and RAM, evolutionary low-power peripherals and security features. This is an ideal solution for sensor hub applications, smart energy, Internet of Things, and edge and concentrator. The enhanced Arm Cortex M0+ is the member of the Cortex-M series of processors targeting microcontroller cores focused on very cost sensitive, low power applications. It has a single 32-bit AMBA AHB-Lite interface and includes an NVIC component. It also has hardware debug functionality including support for simple program trace capability. The processor supports the Armv6-M instruction set (Thumb) architecture including all but three 16-bit Thumb opcodes (52 total) plus seven 32-bit instructions. It is upward compatible with other Cortex-M profile processors.
