ATSAMS70N20B-AN

Overview

The ATSAMS70N20B-AN is a 32-bit microcontroller from the SAM S70 series, featuring an ARM Cortex-M7 core operating at 300MHz. It integrates 1MB of Flash memory and 384KB of SRAM within a 100-LQFP package. The device supports a supply voltage range of 1.62V to 3.6V and operates between -40°C and +105°C. Key peripherals include Ethernet, CANbus, I2C, SPI, UART/USART, USB, QSPI, and MMC/SD/SDIO interfaces.

Feature Summary

Integrated Ethernet MAC with dedicated DMA for high-speed network communication
Supports CANbus and LINbus protocols for automotive and industrial connectivity
Includes multiple high-speed serial interfaces such as SPI, QSPI, and SDIO
Features built-in analog-to-digital and digital-to-analog converters

Applications

Industrial automation controllers requiring robust connectivity
Automotive infotainment and instrument cluster systems
Smart metering and utility infrastructure devices
Medical equipment with display and data logging capabilities

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing board layouts regarding the 100-LQFP footprint. Cross-reference datasheet revisions for any errata or design updates prior to final production implementation.

Selection Notes

Select this component when both Ethernet and CANbus/LINbus support are required in a single MCU. The 1MB Flash capacity suits applications with complex firmware and large codebases. Consider the 300MHz performance for real-time processing tasks involving display control or signal analysis.

Part Context

This part belongs to the SAM S70 family, designed for high-performance embedded applications. It shares architectural similarities with the SAM E70 and V70 series but offers specific peripheral combinations tailored for cost-sensitive yet feature-rich designs. The LQFP package provides a balance between pin count and mounting ease.
