ATSAMS70N20A-CNT

Overview

The ATSAMS70N20A-CNT 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-LFBGA package. The device supports a supply voltage range of 1.7V to 3.6V and operates between -40°C and +105°C. Key peripherals include ten 12-bit ADC channels, two 12-bit DACs, and multiple communication interfaces such as SPI, UART/USART, USB, I2C, IrDA, LINbus, MMC/SD/SDIO, and QSPI.

Feature Summary

• High-performance processing via ARM Cortex-M7 core with DSP instructions
• Integrated analog conversion capabilities with multiple 12-bit ADC and DAC channels
• Comprehensive connectivity suite supporting serial, universal, and mass storage protocols
• On-chip memory architecture providing substantial program storage and data RAM

Applications

• Industrial automation controllers requiring high-speed processing
• Medical devices utilizing precise analog signal acquisition
• Consumer electronics with display and touch interface requirements
• Automotive infotainment systems needing robust connectivity

Procurement Notes

Verify the suffix CNT indicates tape and reel packaging when ordering. Confirm the specific variant matches the required pinout and memory configuration for the target application. Ensure compatibility with development tools such as ATATMEL-ICE for programming and debugging. Check current datasheet revisions for any updates regarding electrical characteristics or recommended operating conditions prior to final design implementation.

Selection Notes

Select this model for applications demanding high computational throughput and extensive peripheral integration in a compact form factor. Compare against the ATSAMS70N20A-CN if tray packaging is preferred over tape and reel. Consider the ATSAME70N20A series if Ethernet connectivity is required instead of the S70's specific interface set. Evaluate power consumption profiles against the 1.7V to 3.6V operating range to ensure system efficiency meets design constraints.

Part Context

This component belongs to the Microchip SAM S70 family, designed for performance-oriented embedded applications. It shares architectural similarities with the SAM E70 and V70 families but offers distinct peripheral configurations tailored for specific market segments. The N20 designation typically denotes the 1MB flash and 384KB RAM configuration within the 100-pin package lineup.

Replacement Considerations

ATSAMS70N20A-CN serves as a direct functional alternative with identical specifications but differs in packaging format (tray versus tape and reel). Designers must verify footprint compatibility when switching between these variants.
