This application note aims at helping the reader to get started with the Atmel® SAM L22 ARM® Cortex®-M0+ based Ultra low-power segment LCD microcontroller.
Atmel | SMART SAM L22 is a series of Ultra low-power segment LCD microcontrollers using the 32-bit ARM Cortex-M0+ processor, ranging from 48- to 100-pins with up to 256KB Flash and 32KB of SRAM and to drive up to 320 LCD segments. The SAM L22 devices operate at a maximum frequency of 32MHz and reach 2.14 Coremark/ MHz. With sophisticated power management technologies the SAM L22 devices run below 50μA/MHz in active mode and below 600nA in ultra-low-power backup mode with RTC.
SAM L22 is targeted for segment LCD and/or Battery powered applications, like sport watches, personal healthcare devices, thermostat with user interface, access control panels and metering (gas, water, energy metering, and basic smart meter) applications.
