ATSAMC20E15A-AUT

Overview

The ATSAMC20E15A-AUT is a 32-bit microcontroller from the Microchip SAM C20 series, built on an ARM Cortex-M0+ core. It features 32KB of in-system programmable Flash memory and 4KB of SRAM. The device operates at a maximum clock frequency of 48MHz and supports a supply voltage range of 2.7V to 5.5V. It includes ten 12-bit ADC channels and one 10-bit DAC. Communication interfaces include I2C, LIN, PMBus, SPI, and USART. The component is housed in a 32-TQFP package with 26 available I/O lines and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates an ARM Cortex-M0+ processor for efficient code execution in resource-constrained applications.
• Provides flexible analog conversion capabilities through multiple high-resolution ADC channels and a dedicated DAC output.
• Supports robust serial communication protocols including LINbus and PMBus for industrial and automotive connectivity.
• Features integrated non-volatile memory for program storage and data retention without external components.

Applications

• Industrial control systems requiring LINbus communication
• Automotive electronics compliant with AEC-Q100 standards
• Battery-powered devices utilizing low-voltage operation modes
• Smart sensors integrating analog signal processing

Procurement Notes

Verify the specific suffix 'AUT' indicates tape and reel packaging and extended temperature range during procurement. Confirm RoHS compliance status via official documentation before integration. Ensure ESD protection measures are applied during handling due to moisture sensitivity classification. Cross-reference the latest datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a 5V tolerant interface and automotive-grade reliability are required alongside standard ARM Cortex-M0+ performance. Compare against the ATSAMC20J series if higher pin counts or different package types like QFN are needed. Consider the ATSAMC21 series if cryptographic security features or higher flash capacity are necessary for the application.

Part Context

This part belongs to the SAM C20 family of 32-bit MCUs designed for cost-sensitive and space-constrained applications. The family emphasizes energy efficiency and peripheral integration suitable for general-purpose embedded tasks. The ATSAMC20E15A variant specifically targets environments requiring wide operating temperatures and automotive qualification standards.

Replacement Considerations

ATSAMC20E15A-AN is the equivalent part number differing only in tray packaging instead of tape and reel. ATSAMD20E15A-AU offers similar specifications but lacks automotive qualification and LINbus support. ATSAML10E15A-AU provides enhanced security features but operates at a lower clock speed and requires a different supply voltage range.
