ATSAMD20E16B-MU

Overview

The ATSAMD20E16B-MU is a 32-bit microcontroller based on the ARM Cortex-M0+ core, manufactured by Microchip Technology. It features 64 kB of Flash program memory and 8 kB of SRAM data memory. The device operates with a maximum clock frequency of 48 MHz and supports a supply voltage range of 1.62 V to 3.63 V. It includes ten 12-bit ADC channels and one 10-bit DAC channel. The component utilizes a 32-VQFN package with dimensions of 5x5 mm and provides 26 I/O lines. It supports interfaces including I2C, SPI, and USART.

Feature Summary

• Integrates an ARM Cortex-M0+ processor core for efficient code execution.
• Includes analog peripherals such as a 12-bit ADC and a 10-bit DAC.
• Supports standard communication protocols via SERCOM modules.
• Operates within a wide industrial temperature range.

Applications

• Industrial control systems
• Consumer electronics devices
• Sensor interface modules

Procurement Notes

Verify the specific suffix 'MU' confirms the 32-VQFN (5x5) package type during procurement. Ensure the order specifies the 'B' variant if functional safety or specific manufacturing lot requirements are necessary. Confirm RoHS compliance status matches project environmental standards. Check for moisture sensitivity level requirements regarding storage and handling procedures before assembly.

Selection Notes

Select this model when a low-power 32-bit MCU with moderate memory capacity is required. The 48 MHz speed suits applications needing faster processing than 8-bit alternatives. The 1.62 V minimum voltage allows battery-powered operation. Compare against ATSAMD20E16A-MU if a wider 2.7V-5.5V supply range is needed instead of the lower voltage option.

Part Context

This component belongs to the SAM D20E series within the Microchip SAM family. These MCUs are designed for cost-sensitive applications requiring 32-bit performance. The series shares architectural similarities with the SAM D21 but offers different peripheral configurations and memory sizes tailored for entry-level embedded control tasks.

Replacement Considerations

ATSAMD20E16A-MU serves as a pin-compatible alternative with a higher minimum operating voltage of 2.7 V. Verify voltage domain compatibility before substitution. Other SAM D20 variants may require software adaptation due to differing peripheral counts or memory sizes.
