ATSAML22-XPRO Visão geral
Background Knowledge: An evaluation kit (eval board) is a printed-circuit assembly produced by a microcontroller vendor that exposes the device's peripherals — GPIOs, communication buses, analog blocks — through standardized headers and on-board sensors so that firmware engineers can prototype firmware before committing to a custom PCB. Within the hierarchy, the ATSAML22-XPRO sits under: evaluation kit -> development board -> engineering tool -> electronic test & measurement instrument. The Xplained Pro family specifically adds an embedded debugger, removing the need for an external programmer.
Key features include a SAM L22 Cortex-M0+ core at up to 32 MHz, 256 KB Flash, 32 KB SRAM, segment LCD controller supporting up to 8 common and 32 segments, 12-bit ADC, multiple SERCOM peripherals, an onboard temperature sensor, an Atmel CryptoAuthentication footprint, and the QTouch slider/pad interface. The kit also offers Arduino Uno R3-compatible headers for shield expansion, a mikroBUS socket for Click board support, and a built-in Li-ion/LiPo charger for battery-powered prototypes.
Architecturally, the ATSAML22N18A die pairs an ARM Cortex-M0+ core with Microchip's proprietary ultra-low-power SleepWalking peripherals and an integrated SLCD driver capable of driving glass displays directly — a combination aimed at wearables, metering, and battery-powered HMI applications where segment LCDs are preferred over TFTs for cost and power reasons.
Typical applications include ultra-low-power IoT sensor nodes with segment LCD readout, smart thermostats, home energy meters, portable medical devices with battery indicator displays, asset-tracking tags, and wearable fitness bands. The kit is supported by Atmel Studio / Microchip Studio and MPLAB X IDE, plus the Atmel START code-configurator.
When designing with this kit, route all SERCOM I/O via the Arduino headers to preserve shield compatibility, and use the on-board 32.768 kHz crystal footprint for RTC accuracy rather than relying on the internal oscillator in metering applications.

Aplicações típicas
ATSAML22-XPRO é adequado para 6 aplicaçãos: Ultra-Low-Power IoT Sensor Node with Segment LCD, Smart Thermostat with Battery Backup, Home Energy Meter Reference Design, Portable Medical / Wearable Device Prototype, Asset-Tracking and RFID Tag Eval, Industrial HMI / Sensor Front-Panel.
Ultra-Low-Power IoT Sensor Node with Segment LCD
The ATSAML22-XPRO's 256 KB Flash, 32 KB SRAM, and integrated segment LCD controller make it ideal for battery-powered IoT sensor nodes that display readings on a low-power glass LCD. The SAM L22's SleepWalking peripherals wake only the necessary logic, keeping quiescent current below 1 uA between sensor reads. This combination delivers multi-year coin-cell life for environmental, water, and gas-meter applications where TFTs would be too power-hungry.
Recomendado
Smart Thermostat with Battery Backup
The ATSAML22-XPRO's Arduino-compatible headers, on-board temperature sensor, and segment LCD make it a strong fit for smart-thermostat prototypes. The SAM L22's 12-bit ADC captures thermistor bridges accurately, while the segment LCD renders setpoint, room temp, and battery status without a TFT. Engineers can validate UI flow on this kit before porting firmware to a smaller custom PCB using the same ATSAML22N18A silicon.
Recomendado
Home Energy Meter Reference Design
Energy-meter designs benefit from the ATSAML22-XPRO's integrated segment LCD driver, which can directly drive the digit glass used in domestic kWh meters. The 32 KB SRAM buffers instantaneous power readings while the on-board QTouch slider footprint supports tamper-detection buttons. The 32.768 kHz crystal footprint provides RTC-grade timekeeping for time-of-use billing profiles.
Recomendado
Portable Medical / Wearable Device Prototype
Medical wearables with battery indicators, pulse-rate displays, and disposable form factors map well to the ATSAML22-XPRO. The on-board Li-ion/LiPo charger supports realistic battery-life profiling, while the segment LCD shows pulse, oxygen saturation, or status icons without the cost of a TFT. The ATSAML22's Class-B safety libraries and UL/IEC 60730-ready firmware make certification pre-work feasible on this kit.
Recomendado
Asset-Tracking and RFID Tag Eval
The ATSAML22-XPRO's low-power sleep modes and CryptoAuthentication footprint are suited to long-life asset-tracking tags. Engineers can prototype BLE or sub-GHz radio add-on shields via the Arduino headers and display tag status (last seen, battery, ID) on the integrated SLCD. The same firmware ports cleanly to the production SAM L22 for shipping cost-down designs.
Recomendado
Industrial HMI / Sensor Front-Panel
Industrial front panels with segment LCDs and QTouch buttons — for example, pump controllers or HVAC valves — can be prototyped on the ATSAML22-XPRO. The mikroBUS socket accepts MikroElektronika Click boards for RS-485, CAN, or 4-20 mA I/O, while the Arduino headers accept third-party HMI shields. The SAM L22's wide operating temperature (-40C to +85C) and integrated ESD protection simplify IEC 61000 EMC pre-compliance work.

Notas de projeto
The ATSAML22N18A on this kit features SleepWalking peripherals that allow ADC and SERCOM peripherals to wake only the relevant logic, keeping quiescent current below 1 uA in deep sleep. For battery-life benchmarking, use the on-board Li-ion charger footprint and a known 3.7 V 1000 mAh cell. Estimated: with 1 sample per minute and segment LCD update, expect 6-12 months runtime from a 1000 mAh cell, validating against the SAM L22 datasheet power profiles.
The Arduino Uno R3-compatible headers map SERCOM0/1/2 onto the standard shield pinout. When wiring 5 V shields, note that all Xplained Pro GPIOs are 3.3 V tolerant only; use level shifters (e.g. TXS0108E) when interfacing 5 V Click boards or sensors to avoid damage to the ATSAML22N18A die.
Do not rely on the SAM L22's internal 32 MHz oscillator for ADC sampling above 500 ksps; route the external 32.768 kHz crystal (Y1 footprint) and PLL up to derive a precise 32 MHz peripheral clock. Failing to do so degrades ADC ENOB and increases noise on the integrated segment LCD bias supply.
Keep the SLCD segment and common traces short and balanced. The SAM L22's segment LCD driver uses charge redistribution to bias the glass; long or unbalanced traces cause ghost segments. Follow the SLCD layout guideline in the ATSAML22 datasheet section on segment routing when porting to a custom PCB.
Informações de conformidade
RoHS / REACH compliance inferred from Microchip's published environmental data for the Xplained Pro family. AEC-Q100 qualification is not stated for the ATSAML22-XPRO kit itself; the underlying ATSAML22N18A MCU has a separate automotive variant (ATSAML22N18A-AUT).
