ATSAMD20E17A-MNT

Overview

The ATSAMD20E17A-MNT is an ARM microcontroller from the SAM D20 series, featuring a Cortex-M0+ core. It integrates 128 kB of Flash program memory and 16 kB of SRAM data RAM. The device operates within a supply voltage range of 1.62 V to 3.63 V and supports a maximum clock frequency of 48 MHz. It utilizes a 32-pin QFN package and includes a 12-bit ADC with 10 channels. The component provides 26 general-purpose I/O pins and supports interfaces including I2C, SPI, and UART/USART. It is rated for an extended operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates a 32-bit ARM Cortex-M0+ processor core for efficient code execution.
• Includes non-volatile Flash memory for program storage and static RAM for data handling.
• Features a 12-bit analog-to-digital converter with multiple input channels.
• Supports standard serial communication protocols such as I2C, SPI, and USART.

Applications

• Low-power embedded control systems
• Industrial sensor nodes
• Portable battery-operated devices

Procurement Notes

Verify the specific suffix MNT indicates tape and reel packaging when ordering. Confirm the voltage range corresponds to the E variant specifications. Ensure the QFN-32 footprint matches the target PCB design. Check for RoHS compliance documentation if required by project standards. Validate the extended temperature rating against environmental requirements.

Selection Notes

Select this model for applications requiring low power consumption and moderate processing speed. The 1.62 V minimum voltage allows operation in ultra-low power scenarios. The 48 MHz clock speed balances performance and energy efficiency. Consider the 128 kB Flash size for firmware complexity. Evaluate the 26 available I/O pins against interface requirements.

Part Context

This component belongs to the Microchip SAM D20 family, which is designed for cost-sensitive and power-efficient applications. The family shares a common architecture but varies in memory size, pin count, and peripheral sets. The E variant typically denotes specific voltage and package configurations within the broader product line.

Replacement Considerations

ATSAMD20E17A-AU offers the same electrical specifications in a TQFP-32 package. ATSAMD20J17A-MNT provides identical core features in a 64-pin QFN package. Verify pin compatibility and package dimensions before substitution.
