ATSAMC20E17A-ANT

Overview

The ATSAMC20E17A-ANT is an ARM microcontroller from the Microchip SAM C20 series, featuring an ARM Cortex-M0+ core. It integrates 32 kB of Flash program memory and 4 kB of SRAM data memory within a 32-pin TQFP package. The device supports a maximum clock frequency of 48 MHz and operates on a supply voltage range of 2.7 V to 5.5 V. It includes a 12-bit ADC with 10 channels and provides 26 general-purpose I/O lines. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range of -40°C to +105°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for enhanced reliability in vehicle environments.
• Extended industrial temperature operation capability spanning from -40°C to +105°C.
• Integrated 12-bit analog-to-digital converter supporting multiple input channels for sensor interfacing.

Applications

• Automotive body electronics and control modules
• Industrial sensor nodes requiring wide temperature tolerance
• General-purpose embedded control systems

Procurement Notes

Verify the specific suffix 'ANT' confirms the 105°C operating temperature rating and TQFP-32 packaging. Confirm AEC-Q100 automotive qualification status matches project requirements. Ensure compatibility with the 2.7V to 5.5V supply voltage range. Check humidity sensitivity level specifications for proper storage and handling procedures during assembly.

Selection Notes

Select this variant when automotive reliability and extended temperature performance are mandatory. The 32 kB Flash and 4 kB RAM suit moderate complexity control tasks. The 48 MHz speed balances processing needs with power efficiency. Verify pinout compatibility if replacing older SAM devices. Consider the TQFP-32 package for standard surface-mount assembly processes.

Part Context

This part belongs to the Microchip SAM C20 family, designed for cost-sensitive and low-power applications. The E17 designation typically indicates specific memory configurations within the E-series. The ANT suffix denotes the extended temperature grade and tape-and-reel packaging format. This family targets automotive and industrial sectors requiring robust MCU solutions.

Replacement Considerations

ATSAMC20E17A-AUT: Identical electrical specifications but rated for -40°C to +85°C temperature range. ATSAMD20E17A-AU: Similar architecture but lacks AEC-Q100 automotive qualification. Verify package dimensions and pin compatibility before substitution.
