Microchip ATSAML22J16A

ARM Cortex-M0+, 32 MHz, 64 kB ROM, 8 kB RAM

The Microchip ǀ SMART SAM L22 ARM Cortex-M0+ based microcontroller series are ideal for IoT, HMI, Building Automation, smart metering, wireless, and any system that needs segment LCD controller, large memories and ultra-low power consumption. With a rich set of peripherals, flexibility and ease-of-use combined with ultra-low power consumption, the SAM L22 is designed for simple and intuitive migration between SAM L devices due to identical peripheral modules, compatible code and a linear address map. The SAM L22 is also compatible with the SAM D family of general-purpose MCUs.
