SAM L MCUs

Setting a New Low Power Benchmark for ARM® Cortex®-M23 & ARM® Cortex® - M0+  -Based Microcontrollers

Microchip SAM L family of microcontrollers (MCUs) are built with innovative picoPower® Technology to deliver best-in-class low power consumption down to 25 µA/MHz in active mode, under 100nA in sleep mode and fast wake-up times of 1.2uS. These MCUs have achieved EEMBC certified ULPMark Score of 405, which is the highest score for an ARM® Cortex®-M23 or ARM® Cortex®- M0+ class device. In addition to ultra-low-power capabilities, these devices feature enhanced Peripheral Touch Controller, chip-level robust security, ARM®TrustZone® Technology, AES, Full Speed USB host and device, Event System and Sleepwalking, 12-bit analog, built in opAmps and much more. With the Internet of Things (IoT) market predicted to grow to billion devices by 2020 and the widespread use of wearables & low power accessories, designers increasingly need lower-power, robust security and touch interfaces —The SAM L series is designed to meet the needs of these applications, expanding battery life from years to decades while adding elegant touch and securing the IoT nodes.

Key Features:

  • picoPower Technology — picoPower devices are designed from the ground up for lowest possible power consumption from transistor design and process geometry, sleep modes, flexible clocking options, on-the-fly user-selectable performance levels, event system to SleepWalking peripherals. These devices can operate down to 1.62V while still maintaining all functionality, including analog functions. They have short wake-up time, with multiple wake-up sources from even the deepest sleep modes. They utilize low leakage processes and libraries to deliver industry-leading low power consumption in active and all sleep modes.
  • QTouch® Peripheral Touch Controller — Offers built-in hardware support for buttons, sliders, wheels, surfaces, and proximity, and supports both mutual and self-capacitive touch without the need for external components. It offers superior water tolerance, excellent sensitivity, faster response times and high noise immunity, as well as self-calibration, making any user tuning superfluous.
  • Robust Security: Offers chip-level tamper resistance, ARM®  TrustZone®, secure boot, secure bootloader, AES, secure key storage, TRNG and secure debug.
  • 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, you can tailor the peripheral mix precisely to your application. The I2C™ can operate up to 3.4 MHz (PMBus and SMBus are also supported). The SAM L22, SAM L10, and SAM L11 also support 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.
  • Scalability — Flash memory densities range from 16KB to 256KB and up to 40kB of SRAM with packages as small as 2.8 x 2.8 mm and ranging from 24- to 100-pin options.
