ATSAMS70N21A-ANT

Overview

The ATSAMS70N21A-ANT is a 32-bit microcontroller from the Microchip SAM S70 series, featuring an ARM Cortex-M7 core operating at 300 MHz. It integrates 2 MB of flash memory and 384 KB of SRAM within a 100-pin LQFP package. The device supports a supply voltage range of 1.7 V to 3.6 V and includes ten 12-bit ADC channels. Connectivity options include SPI, UART/USART, and USB interfaces, with an operating temperature range of -40°C to +105°C.

Feature Summary

• High-performance processing via ARM Cortex-M7 core running at 300 MHz
• Integrated non-volatile storage with 2 MB flash and 384 KB SRAM
• Analog signal acquisition capability through ten 12-bit ADC channels
• Standard communication support including SPI, UART/USART, and USB

Applications

• Industrial control systems requiring robust processing
• Medical devices utilizing analog input capabilities
• Automotive applications needing wide temperature operation
• Consumer electronics with USB connectivity requirements

Procurement Notes

Verify the specific suffix 'ANT' corresponds to the tape and reel packaging format as indicated by distributor listings. Confirm that the component meets RoHS compliance standards for your region. Ensure the ordering quantity aligns with the manufacturer's standard reel specifications. Cross-reference the datasheet revision date to confirm technical accuracy before finalizing procurement.

Selection Notes

Select this model when 2 MB of program storage and 384 KB of RAM are required for complex firmware execution. Choose the LQFP-100 package if surface-mount assembly with 75 available I/O pins is preferred over BGA or QFN alternatives. Consider this part for designs needing integrated USB functionality without external transceivers. Evaluate the 300 MHz clock speed against power consumption constraints in battery-operated scenarios.

Part Context

This component belongs to the SAM S70 family, which targets high-performance embedded applications. The series shares architectural similarities with the E70 and V71 families but offers distinct memory and peripheral configurations. The N-series designation typically indicates specific pin counts and package types within the broader product line.

Replacement Considerations

ATSAMS70N21A-CN serves as a tray-packaged alternative with identical electrical characteristics. ATSAMS70N20B-ANT provides similar performance but with reduced 1 MB flash memory. ATSAMS70J21B-ANT offers a smaller 64-pin package option with fewer I/O pins.
