ATSAMD20J14A-AUT

Overview

The ATSAMD20J14A-AUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48MHz. It features 16KB of in-system programmable Flash memory and 2KB of SRAM. The device supports a supply voltage range of 1.62V to 3.63V and includes an internal oscillator. It provides 52 general-purpose I/Os and integrates multiple communication interfaces including I2C, SPI, and USART. Analog capabilities consist of 20 channels of 12-bit ADC and one 10-bit DAC.

Feature Summary

• Integrates ARM Cortex-M0+ processor for efficient code execution
• Includes built-in analog-to-digital and digital-to-analog converters
• Supports standard serial communication protocols
• Features low-power operation with internal clock sources

Applications

• Battery-powered portable devices
• Industrial control systems
• Consumer electronics peripherals

Procurement Notes

Verify the suffix 'AUT' indicates tape and reel packaging distinct from the 'AU' tray variant. Confirm the specific temperature grade and voltage range requirements match the application design. Check current datasheet revisions for errata updates before finalizing hardware designs.

Selection Notes

Select this model when 16KB program storage and 52 I/O pins are required in a compact form factor. Compare against ATSAMD20J14B-AU for potential package or speed variations within the same memory configuration. Ensure the 1.62V to 3.63V supply range aligns with the system power architecture.

Part Context

This component belongs to the SAM D20 family of microcontrollers. It shares the core architecture with other SAM D20 variants but differs in memory size, I/O count, and package type. The J-series typically offers higher pin counts compared to E-series counterparts.

Replacement Considerations

ATSAMD20J14A-AU serves as the tray-packaged equivalent. ATSAMD20J14B-AU may offer alternative packaging or minor specification differences.
