Overview
The ATSAML22G17A-UUT is a 32-bit ARM Cortex-M0+ microcontroller from the Microchip SAML22 family. It features 128 kB of Flash program memory and 16 kB of SRAM data RAM. The device operates within a supply voltage range of 1.62 V to 3.63 V and supports a maximum clock frequency of 32 MHz. It includes a 12-bit ADC with 10 channels, 36 general-purpose I/Os, and four timers/counters. The component is housed in a WLCSP-49 package and is rated for an industrial operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates USB functionality alongside standard communication interfaces such as I2C, SPI, and USART.
- Includes on-chip EEPROM memory for non-volatile data storage.
- Supports low-power operation modes suitable for energy-constrained applications.
Applications
- USB-enabled peripheral devices
- Smart card implementations
- Industrial control systems requiring robust communication interfaces
Procurement Notes
Verify the specific suffix UUT corresponds to the WLCSP-49 package and industrial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the required soldering profile for wafer-level chip-scale packaging technologies.
Selection Notes
Select this model when USB connectivity is required alongside moderate memory capacity in a compact footprint. Compare against the ATSAML22G17A-AUT if TQFP packaging is preferred over WLCSP. Evaluate the ATSAML22G18A series if higher Flash or RAM capacities are necessary for the application requirements.
Part Context
This component belongs to the SAM L22 ultra-low-power MCU family designed for cost-sensitive and space-constrained embedded applications. The G17 variant specifically targets designs needing integrated USB capabilities without external transceivers. It complements other SAML22 parts by offering a balance of processing power and peripheral richness in a minimal form factor.
Replacement Considerations
ATSAML22G17A-AUT offers identical core specifications but utilizes a TQFP-48 package instead of WLCSP-49. ATSAML22G18A variants provide increased memory resources (256 kB Flash, 32 kB RAM) while maintaining similar performance characteristics.
