ATSAMS70Q21B-CFN

Overview

The ATSAMS70Q21B-CFN is a 32-bit microcontroller from the SAM S70 series, featuring an ARM Cortex-M7 core operating at 300MHz. It integrates 2MB of Flash memory and 384KB of SRAM within a 144-pin LFBGA package. The device supports a supply voltage range of 1.7V to 3.6V and includes 114 I/O pins. Key peripherals include 24-channel 12-bit ADCs, 12-bit DACs, USB, SPI, UART, USART, and DMA controllers.

Feature Summary

High-performance processing via ARM Cortex-M7 core with DSP instructions
Integrated analog conversion capabilities with multiple 12-bit ADC channels
Comprehensive connectivity suite including USB and standard serial interfaces
Direct Memory Access controller for efficient data throughput management

Applications

Industrial control systems requiring high-speed processing
Human-machine interface (HMI) displays
Medical equipment with analog signal acquisition needs
Automotive infotainment and instrument clusters

Procurement Notes

Verify the specific suffix 'CN' against the manufacturer's official datasheet to confirm environmental compliance and material declarations. Ensure the 144-LFBGA footprint matches your PCB design constraints. Confirm that the 1.7V minimum supply voltage aligns with your system power architecture before finalizing procurement.

Selection Notes

Select this model when 2MB of program storage and 384KB of RAM are required for complex applications. The 144-pin package provides extensive I/O options compared to smaller variants. Consider the 300MHz clock speed for real-time processing demands. Verify compatibility with existing development tools in the SAM S70 ecosystem.

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 V71 series but offers specific memory and peripheral configurations tailored for cost-sensitive yet powerful solutions. The Q21 variant specifically denotes the 2MB Flash capacity tier.
