K32L3A
K32L3A60VPJ1AT
72 MHz Arm® Cortex®-M0+/M4F Dual Core Microcontroller
with up to 1280 KB Flash and 384 KB SRAM
The K32L3A family of devices is an ultra-low-power, dual core
solution ideal for applications that require a high performance
Cortex-M4F processor to run the application and an efficient
Cortex-M0+ to run low power operations such as sensor data
collection and perform low level operations that don't need the
full power of the M4 core.
