Overview
The ATSAMD51G18A-MUT is a 32-bit microcontroller based on the ARM Cortex-M4F core, operating at a maximum frequency of 120 MHz. It features 256 KB of in-system programmable flash memory and 128 KB of SRAM. The device is housed in a 48-VQFN package with exposed pad and supports an operating voltage range of 1.71 V to 3.63 V. It includes integrated USB Full-Speed controller, multiple communication interfaces, and a 12-bit ADC.
Feature Summary
- Integrates an ARM Cortex-M4F processor with hardware floating-point unit for efficient signal processing.
- Includes a dedicated USB Full-Speed device/controller peripheral for connectivity applications.
- Features low-power modes including Run, Idle, Sleep, Backup, and HIB to optimize energy consumption.
Applications
- USB-enabled consumer electronics and peripherals
- Industrial control systems requiring real-time processing
- Medical devices with analog signal acquisition needs
Procurement Notes
Verify the specific suffix 'MUT' corresponds to the 48-VQFN package and tape-and-reel shipping configuration. Confirm that the operating temperature range meets the application requirements, as industrial variants may differ. Ensure compatibility with the intended power supply voltage levels within the specified 1.71 V to 3.63 V range before finalizing procurement.
Selection Notes
Select this component when a balance of computational performance and connectivity is required. The Cortex-M4F core offers higher throughput than M0+ variants while maintaining reasonable power efficiency. The inclusion of USB hardware reduces CPU overhead compared to bit-banging solutions. Consider pin count and memory size relative to alternative SAM D51 family members to ensure optimal cost-performance fit.
Part Context
This part belongs to the Microchip SAM D51 family, designed for high-performance embedded applications. It shares architectural similarities with other SAM D5x devices but differs in memory size and package options. The G18 variant specifically denotes the 256 KB flash and 128 KB RAM configuration within the QFN footprint.
Replacement Considerations
Direct substitutes within the same family include ATSAMD51G18A-MFT (extended temperature range) or ATSAMD51G18A-AU (TQFP package). Cross-family replacements like ATSAMD51J18A require interface and pinout verification.
