Atmel has recently announced the addition of the SAM L22 series to its family of secure, ARM® Cortex® M0+-based MCUs. These new devices offer a built-in, ultra-low power capacitive touch interface with a segment LCD controller that can deliver up to 320 segments. Typical applications for these controllers would include low-power devices such as thermostats, electric/gas/water meters, home control, medical and access systems.
Their inbuilt features make them suited to IoT applications and the SAM L22 series includes security capabilities to deliver 256-bit AES, cyclic redundancy check (CRC), true random number generator, Flash protection and tamper detection to ensure information is securely stored, delivered and accessible. The devices use Atmel’s proprietary picoPower® technologies for low power consumption and smart low-power peripherals that work independently of the CPU in sleep modes.
