Overview
The ATSAMD20E16A-AN is an 8-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 16 KB of in-system programmable Flash memory and 2 KB of SRAM. The device includes a comprehensive set of peripherals such as USB 2.0 Full-Speed interface, multiple USARTs, SPI interfaces, I2C interfaces, and various timers. It operates within a voltage range of 1.6 V to 3.6 V and supports up to 23 general-purpose I/O pins depending on the package configuration.
Feature Summary
- Integrates an ARM Cortex-M0+ processor core for efficient code execution with low power consumption characteristics.
- Includes a built-in USB 2.0 full-speed controller enabling direct connectivity without external transceivers.
- Provides flexible peripheral options including multiple serial communication interfaces and analog-to-digital converters.
Applications
- USB-enabled consumer electronics devices
- Simple industrial control systems requiring serial communication
- Portable battery-powered instruments
Procurement Notes
Verify the specific suffix 'AN' against the manufacturer's official documentation to confirm package type and temperature range specifications. Ensure compatibility with existing board layouts regarding pin assignments and voltage levels before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a low-cost ARM-based solution with native USB support is required. Consider the limited Flash and SRAM sizes relative to application complexity. Evaluate power supply requirements against the specified 1.6 V to 3.6 V operating range.
Part Context
This model belongs to the Microchip SAM D20 family of microcontrollers designed for cost-sensitive applications. The family shares common architectural features while differing in memory size and peripheral counts. The E16 variant specifically denotes the 16 KB Flash capacity within this series.
Replacement Considerations
Direct replacements may include other SAM D20 variants with different memory sizes, provided pin compatibility is maintained. Verify functional equivalence of USB controllers and peripheral sets when substituting with similar ARM Cortex-M0+ devices from other manufacturers.
