ATSAMD20G15B-MUT

Overview

The ATSAMD20G15B-MUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48MHz. It features 32KB of Flash memory and 4KB of SRAM within a 48-VQFN package with exposed pad. The device supports a supply voltage range of 2.7V to 5.5V and includes 14 channels of 12-bit ADC and one 10-bit DAC. Communication interfaces include I2C, SPI, and UART/USART. It operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates an ARM Cortex-M0+ processor for efficient 32-bit execution
• Provides flexible connectivity via I2C, SPI, and USART peripherals
• Includes analog conversion capabilities with multiple 12-bit ADC channels

Applications

• General-purpose embedded control systems
• Low-power sensor interface nodes
• Industrial communication gateways

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 48-VQFN footprint matches the PCB design constraints. Ensure the 2.7V to 5.5V supply voltage range aligns with the target system power architecture before finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate I/O count and analog performance is needed without USB connectivity. The wider supply voltage range compared to other SAM D20 variants allows for direct interfacing with 5V logic systems. Consider the 48-pin QFN package size relative to available board space and thermal dissipation requirements for the specific application environment.

Part Context

This part belongs to the Microchip SAM D20G family, designed for cost-sensitive applications requiring ARM Cortex-M0+ performance. It shares architectural similarities with the SAM D21 series but lacks functional safety certifications and USB controllers found in higher-tier models. The G-series designation indicates specific pinout and peripheral configurations distinct from E or J series variants.

Replacement Considerations

ATSAMD20G15A-MUT: Older silicon revision with potential errata differences; verify compatibility with existing firmware.
