Overview
The ATSAMC20E16A-AUTS2 is an ARM Cortex-M0+ microcontroller from the SAM C20 family, manufactured by Microchip Technology. It features a 48 MHz maximum clock frequency and integrates 64 kB of Flash program memory with 8 kB of SRAM data RAM. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an industrial temperature range of -40°C to +85°C. It provides 26 general-purpose I/O pins and includes a 12-bit ADC with 10 channels. Connectivity options include I2C, SPI, UART/USART, and CAN bus interfaces.
Feature Summary
- Integrates a high-accuracy RC48 oscillator for reliable clocking without external components.
- Supports automotive-grade operation with extended industrial temperature specifications.
- Includes integrated CAN bus interface for robust communication in networked systems.
Applications
- Automotive body electronics and control modules
- Industrial sensor nodes requiring CAN connectivity
- Low-power embedded control applications
Procurement Notes
Verify the specific suffix 'AUTS2' against official Microchip documentation to confirm the presence of the high-accuracy RC48 oscillator and tape-and-reel packaging configuration. Ensure the component meets the required automotive or industrial qualification standards specified in the datasheet before integration into final designs.
Selection Notes
Select this variant when a built-in high-accuracy internal oscillator is required to reduce bill-of-materials complexity. The inclusion of CAN bus support makes it suitable for applications needing direct serial communication capabilities. Confirm that the 32-TQFP package dimensions align with the target PCB layout constraints.
Part Context
This component belongs to the SAM C20 family of 32-bit ARM Cortex-M0+ microcontrollers. The series is designed for cost-sensitive applications requiring moderate performance and peripheral integration. The 'E16' designation typically indicates the specific memory configuration within the family lineup.
Replacement Considerations
Consult the official Microchip SAM C20 family cross-reference guide for verified pin-compatible or functionally equivalent alternatives. Verify that any substitute part maintains the same package type and electrical characteristics.
