Microchip Technology SAM L22 ARM-based Microcontrollers

Microchip SAM L22 ARM-based Microcontrollers (MCUs) are ultra-low-power segment LCD microcontrollers using the 32-bit ARM® Cortex®-M0+ processor. These MCUs drive up to 320 LCD segments and range from 48- to 100-pins with up to 256KB Flash and 32KB of SRAM. The SAM L22 devices operate at a maximum frequency of 32MHz and reach 2.46 CoreMark®/MHz.
