ATSAMD20E17A-AUT

Overview

The ATSAMD20E17A-AUT is an ARM microcontroller from the SAMD20 series, featuring a Cortex-M0+ core operating at a maximum frequency of 48 MHz. It integrates 128 kB of Flash program memory and 16 kB of SRAM data RAM within a 32-TQFP package. The device supports a supply voltage range of 1.62 V to 1.95 V and operates between -40°C and +85°C. Key peripherals include ten 12-bit ADC channels, six timers/counters, and interfaces such as I2C, SPI, and UART.

Feature Summary

Integrates non-volatile Flash memory for persistent code storage alongside static RAM for runtime data handling.
Includes multiple serial communication interfaces to facilitate connectivity with peripheral devices and sensors.
Features analog-to-digital conversion capabilities for processing external analog signals into digital data.

Applications

Industrial control systems requiring robust serial communication
Sensor interface modules utilizing analog input channels
General-purpose embedded applications within specified temperature ranges

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements, as this variant specifies a narrow supply range distinct from other SAMD20 models. Confirm moisture sensitivity level handling procedures during assembly to prevent damage.

Selection Notes

Select this component when a balance of moderate memory capacity and low power consumption is required for cost-sensitive designs. Compare pin counts and peripheral sets against alternative SAMD20 variants to ensure sufficient I/O availability. Validate that the 1.62 V to 1.95 V supply constraint aligns with the target board's power architecture.

Part Context

This part belongs to the SAMD20 family of 32-bit microcontrollers based on the ARM Cortex-M0+ processor. The family emphasizes energy efficiency and performance for battery-powered applications. The 'E' designation typically indicates a specific pin count and peripheral configuration within the broader SAMD20 product line.
