            SAM L22 Series Microcontrollers
                    Microchip offers its SAM L22 ultra-low-power segment LCD MCUs operating at a maximum frequency of 32 MHz and reaching 2.46 Coremark®/MHz.
    

Image of Atmel's SAM L22 Series Microcontrollers Microchip's Atmel 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.

Key Features

Low power: Market-leading power-saving techniques include a 12-channel event system that allows peripherals to communicate directly with each other without involving the CPU. Microchip SleepWalking peripherals gate both the clock and power to reduce leakage and switching, and only wake the CPU upon a pre-qualified event, achieving an ultra-low power consumption of 35 µA/MHz in active mode and a ULPBench score of 185.8, reducing overall power consumption.
Peripheral flexibility: An innovative serial communication module (SERCOM) is fully software-configurable to handle I²C, USART/UART, and SPI communications. With multiple SERCOM modules on a device, the peripheral mix can be tailored precisely to the application. The I²C can operate up to 3.4 MHz (I²S, PMBus, and SMBus are also supported). The SAM L22 also supports the ISO7816 Interface.
DMA: The SAM L family features a 16-channel DMA controller supporting both memory and peripheral data transfers.

Full-speed USB: The SAM L21 supports both USB embedded Host and USB device modes, while the SAM L22 supports full-speed USB device mode. Full-speed USB is supported in Device mode using an internal RC oscillator, reducing BOM cost and design complexity.
Microchip QTouch^® peripheral touch controller: The QTouch controller offers built-in hardware support for buttons, sliders, wheels, and proximity, and supports both mutual and self-capacitive touch without the need for external components. It offers superb sensitivity and noise tolerance, as well as self-calibration, making any user tuning superfluous.
Scalability: Flash memory densities range from 32 KB to 256 KB and up to 40 KB of SRAM with packages ranging from 32- to 100-pin options.
