ATSAMC20E16A-AUT

Overview

The ATSAMC20E16A-AUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 128 KB of in-system programmable Flash memory and 16 KB of SRAM. The device supports a supply voltage range of 2.7 V to 5.5 V and includes an integrated 10-channel 12-bit ADC. Connectivity options include LIN, I2C, PMBus, SPI, and USART interfaces. It is housed in a 32-TQFP package with 26 available I/O lines.

Feature Summary

• ARM Cortex-M0+ processor core for efficient code execution
• Integrated high-accuracy 48 MHz RC oscillator
• Supports automotive AEC-Q100 qualification standards
• Includes multiple communication peripherals including LIN and PMBus

Applications

• Automotive body electronics modules
• Industrial control systems requiring LIN bus connectivity
• Power management monitoring devices using PMBus
• General-purpose embedded applications in consumer electronics

Procurement Notes

Verify the specific suffix 'AUT' indicates tape and reel packaging and automotive-grade qualification when sourcing. Confirm the manufacturer is Microchip Technology, formerly Atmel. Ensure the component meets RoHS compliance requirements for your assembly process. Check for any recent Product Change Notifications regarding assembly sites or materials.

Selection Notes

Select this part if your design requires 5V operation alongside automotive reliability standards. The inclusion of LIN and PMBus interfaces makes it suitable for networked power and body control applications. Consider the 128 KB Flash size against your firmware requirements. Evaluate the 32-TQFP package dimensions for PCB layout constraints compared to other SAM C20 variants.

Part Context

This component belongs to the ATSAM C20 family, which provides low-power, cost-effective solutions based on the ARM Cortex-M0+ architecture. The family is designed for applications needing moderate performance with extensive peripheral integration. The ATSAMC20E16A variant specifically targets environments requiring robust communication protocols like LIN and PMBus.

Replacement Considerations

ATSAMC20E16A-AU offers identical specifications in tray packaging instead of tape and reel. ATSAMC20G15A-AUT provides similar functionality but with reduced memory (32 KB Flash) and a different pin count (48-TQFP). Verify pin compatibility and software library support before substituting.
