ATSAML22-XPRO-B Présentation
A Xplained Pro evaluation kit (sometimes called a Starter Kit or Dev Kit) is a Microchip-branded development platform that integrates the target MCU with a built-in programmer/debugger, standard extension headers, and reference peripherals. It belongs to the broader hierarchy: development board -> MCU evaluation kit -> ARM Cortex starter platform, designed to accelerate firmware bring-up, peripheral evaluation, and reference design reuse before committing to a custom PCB.
Key features of the ATSAML22-XPRO-B include the SAM L22 MCU running at up to 32 MHz, 256 KB Flash, 32 KB SRAM, a 4x40 segment LCD controller, Peripheral Touch Controller (PTC), 16-bit timers, and full-speed USB support on certain SAM L22 variants. The board's SleepWalking technology lets peripherals wake the CPU only on relevant events, achieving 39 µA/MHz active and 490 nA in ultra-low-power backup mode per the SAML22 family datasheet. The on-board nEDBG provides drag-and-drop programming, virtual COM port, and CMSIS-DAP debugging without an external programmer.
Typical applications for this kit include wearable and battery-powered IoT sensor nodes, ultra-low-power human-machine interface (HMI) prototypes with segment LCD + touch, industrial metering and HVAC user panels, and portable medical/fitness devices. The built-in segment LCD and touch make it especially suited for thermostat, remote control, and appliance front-panel designs where power budget is critical.
When designing with the ATSAML22-XPRO-B, engineers typically use Microchip Studio (Atmel Studio legacy) or MPLAB X IDE with the START code-configurator to generate peripherals and ASF (Advanced Software Framework) drivers. Pin-mapping documentation ships in the user guide PDF and the on-board silk-screen, allowing direct translation to a custom design.

Applications typiques
ATSAML22-XPRO-B convient pour 6 applications: Wearable IoT Sensor Prototypes, Battery-Powered Thermostat / HVAC Panel, Industrial Metering User Interface, Portable Medical / Fitness Devices, Smart Home Sensor Hubs, Appliance Front-Panel Reference Designs.
Wearable IoT Sensor Prototypes
The ATSAML22-XPRO-B fits wearable IoT sensor prototypes because the SAM L22 MCU consumes only 39 µA/MHz active and drops to 490 nA in backup mode per the SAML22 family datasheet. The board's on-board debugger (nEDBG) lets engineers flash firmware and measure current without an external programmer. The integrated PTC touch controller allows wearable user interfaces (button, slider) without extra hardware, while the segment LCD enables wrist-mounted HMI at sub-1 µA standby cost. Use Microchip Studio and ASF for SAM L22 peripheral setup; SleepWalking peripheral events ensure the CPU only wakes on meaningful sensor triggers.
Recommandé
Battery-Powered Thermostat / HVAC Panel
The ATSAML22-XPRO-B is well suited for battery-powered thermostat and HVAC front-panel prototypes because the integrated 4x40 segment LCD controller and PTC touch peripheral cover both display and user-input needs on a single MCU. The SAM L22's 490 nA backup mode with RTC retention enables multi-year coin-cell operation for wall thermostats, and the Cortex-M0+ core at 32 MHz is fast enough for basic PID control loops. The Xplained Pro extension headers allow connection to off-board temperature, humidity, and CO2 sensors using standard mikroBUS click boards.
Recommandé
Industrial Metering User Interface
The ATSAML22-XPRO-B enables industrial metering UI prototypes, especially electricity, water, or gas meters requiring a low-power segment-LCD display and capacitive touch buttons. The SAM L22's 32 KB SRAM and 256 KB Flash hold metering firmware stacks and small GUI assets, while SleepWalking lets UART, timer, or external interrupt peripherals wake the CPU only when a button press occurs. The board's mikroBUS socket accepts standard sensor clicks (e.g., temperature, pressure) used in metering end products. ROHS3 compliance supports metering designs sold globally.
Recommandé
Portable Medical / Fitness Devices
The ATSAML22-XPRO-B is ideal for portable medical and fitness device prototypes including pedometers, glucose meters, and wearable health monitors. The SAM L22's ultra-low-power SleepWalking peripherals are crucial because medical wearables spend most of the time in deep sleep, waking only on sensor events or scheduled heart-rate intervals. The integrated PTC touch and segment LCD provide user interface without extra components, and the Cortex-M0+ core runs enough DSP for basic filtering. The on-board debugger supports IEC 62304-style firmware development workflows with MPLAB XC32 compiler.
Recommandé
Smart Home Sensor Hubs
The ATSAML22-XPRO-B is suitable for smart home sensor hub prototypes combining motion, temperature, and touch interfaces into a single battery-powered device. The SAM L22 integrates up to 16 channels of PTC touch plus segment LCD in a single MCU, eliminating external touch ICs and reducing BOM cost. The on-board nEDBG debugger enables drag-and-drop firmware updates over USB during development. Use ASF or MPLAB Harmony v3 for SAM L22 peripheral setup; connect to off-board radios (LoRa, BLE, sub-GHz) via mikroBUS for full smart-home stack prototyping.
Recommandé
Appliance Front-Panel Reference Designs
The ATSAML22-XPRO-B is appropriate for appliance front-panel reference designs such as washing machine, oven, or dishwasher control panels with capacitive buttons and segment LCD readouts. The SAM L22's Peripheral Touch Controller supports both button and slider gestures needed for modern appliance UX, and SleepWalking keeps power consumption low when the user is not interacting. The Xplained Pro form factor and mikroBUS socket allow integration of power-monitoring or motor-control click boards to demonstrate full appliance firmware on a single development platform.

Principaux différenciateurs
- Integrated 4x40 segment LCD controller on the target MCU (vs ATSAML21-XPRO-B)
- Ultra-low-power SleepWalking peripheral event system (vs ATSAMG55-XPRO)
- Industry-standard Xplained Pro + mikroBUS ecosystem (vs ATSAMHA1G16A-XPRO)
Notes de conception
Estimated: when prototyping battery-powered designs with the ATSAML22-XPRO-B, remove the on-board nEDBG debugger's USB bridge power from the measurement loop by cutting the 3.3V LDO jumper or using the board's current-measurement header. The SAM L22N18A target MCU consumes 39 µA/MHz active and 490 nA in backup mode per the SAML22 family datasheet, so a poorly-isolated measurement can show 50-100x higher current than the MCU itself.
Critical: do not power the kit from both USB and an external 3.3V source simultaneously. The ATSAML22-XPRO-B is designed to be USB-powered for development only; in end products, the SAM L22N18A is the MCU and power management must follow the SAML22 family datasheet recommendations for input voltage, decoupling, and segment LCD bias generation. The on-board debugger circuitry is not present in a production design.
Recommended: when migrating from ATSAML22-XPRO-B to a custom PCB, replicate the Xplained Pro standard extension header pin mapping (J1, J2, J3, mikroBUS) to preserve compatibility with the broad ecosystem of mikroBUS click boards. The kit user guide PDF (document 60001428B family) contains the official pin-assignment table; copying it directly avoids re-engineering peripheral routing for each new prototype.
