ATSAMD21E17L-AFT

Overview

The ATSAMD21E17L-AFT is a 32-bit microcontroller from the SAM D21G series, featuring an ARM Cortex-M0+ core operating at 48MHz. It integrates 128KB of Flash memory and 16KB of SRAM within a 32-TQFP package. The device supports a supply voltage range of 1.62V to 3.63V and operates between -40°C and 125°C. It includes 14-channel 12-bit ADCs, one 10-bit DAC, and interfaces such as I2C, SPI, USART, and LINbus.

Feature Summary

• Functional Safety (FuSa) qualification for automotive applications
• AEC-Q100 grade certification for reliability
• Extended industrial temperature range operation
• Integrated DMA controller for efficient data transfer

Applications

• Automotive body electronics
• Industrial control systems
• Consumer devices requiring functional safety
• Sensor interface modules

Procurement Notes

Verify the specific suffix 'L' indicates the extended temperature range and packaging type. Confirm AEC-Q100 compliance requirements match your design specifications. Check for RoHS and REACH status in official datasheets. Ensure pin compatibility with existing PCB layouts for the 32-TQFP form factor.

Selection Notes

Select this component when functional safety standards are mandatory. Compare RAM and Flash sizes against other SAM D21 variants. Consider the 48MHz clock speed for processing requirements. Evaluate peripheral counts like ADC channels against system needs.

Part Context

Part of the SAM D21 family designed for low-power, high-performance applications. The E17 variant offers higher memory capacity than base models. The L suffix typically denotes specific environmental or packaging attributes within Microchip's naming convention.

Replacement Considerations

ATSAMD21E17D-AUT: Similar specs but different package and temperature range. ATSAMD21E17L-AFTTR: Same electrical characteristics, different tape-and-reel packaging.
