Overview
The ATSAML22J17A-AUT is a 32-bit microcontroller from the SAM L22J series, built on an ARM Cortex-M0+ core. It features 128KB of in-system programmable flash memory and 16KB of SRAM. The device operates at a maximum frequency of 32MHz with a supply voltage range of 1.62V to 3.63V. It includes 16 channels of 12-bit ADCs, supports I2C, SPI, UART/USART, and USB interfaces, and offers 50 general-purpose I/O pins. Packaged in a 64-TQFP (10x10) format, it functions within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates a Peripheral Touch Controller (PTC) for capacitive touch sensing applications without external components.
- Includes a Segment LCD Controller capable of driving complex display segments directly.
- Supports advanced analog peripherals including multiple comparators and high-resolution data converters.
- Provides hardware-accelerated security features via AES encryption modules.
Applications
- Battery-powered wearable devices requiring low power consumption and touch input
- Industrial control systems utilizing segment LCD displays for user interface
- USB-enabled consumer electronics and peripheral devices
- Smart home automation nodes with analog sensor integration
Procurement Notes
Verify the specific suffix 'AUT' confirms automotive-grade qualification if required by your design specifications. Confirm the package type matches your PCB footprint requirements. Check the latest datasheet revision for any errata or pinout updates before finalizing production designs. Ensure compatibility with your chosen development tools and debuggers for the SAM L22 family.
Selection Notes
Select this component when a balance of moderate flash capacity and extensive analog/touch peripherals is needed. It is suitable for designs requiring direct LCD driving and USB connectivity without external controllers. Consider alternative SAM L22 variants if higher clock speeds or different I/O counts are necessary. Evaluate power consumption profiles against specific application duty cycles.
Part Context
This part belongs to the SAM L22 family of ultra-low-power microcontrollers designed for cost-sensitive and battery-operated applications. The J-series variant typically offers a mid-range configuration within the family, providing sufficient resources for complex user interfaces and connectivity options while maintaining energy efficiency standards typical of the Cortex-M0+ architecture.
Replacement Considerations
ATSAML22J18A-AUT: Offers increased flash memory (256KB) with identical pinout and peripherals. ATSAML22J16A-AUT: Provides reduced flash (64KB) and RAM (8KB) but maintains the same package and core functionality.
