ATSAME70Q21A-CFN

Overview

The ATSAME70Q21A-CFN is a 32-bit microcontroller from the SAM E70 series, featuring an ARM Cortex-M7 core operating at 300MHz. It integrates 2MB of flash memory and 384KB of SRAM within a 144-LFBGA package. The device supports a supply voltage range of 1.7V to 3.6V and includes extensive connectivity options such as Ethernet, USB, CANbus, and various serial interfaces. It also provides 24-channel 12-bit ADCs and dual 12-bit DACs for analog applications.

Feature Summary

• Integrates high-performance ARM Cortex-M7 processor with single-precision FPU for complex control algorithms
• Includes dedicated Ethernet MAC with DMA for robust network communication capabilities
• Features multiple high-speed peripheral interfaces including QSPI, SDIO, and USB OTG
• Provides extensive analog conversion resources with numerous 12-bit ADC channels

Applications

• Industrial motor control systems requiring precise timing and processing
• Human-machine interface (HMI) panels with graphical displays
• Smart energy metering devices with advanced communication protocols
• Medical equipment requiring reliable data acquisition and processing

Procurement Notes

Verify the specific suffix CFN indicates the LFBGA-144 package variant when sourcing. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure design compatibility with the 1.7V to 3.6V operating voltage range. Check for any recent product change notices affecting pinout or electrical characteristics.

Selection Notes

Select this component when Ethernet connectivity and large memory capacity are required alongside high-speed processing. Compare against the ATSAMS70 series if Ethernet is not needed, as it offers similar CPU performance without the network controller. Consider the ATSAME70Q21A-CN for tray packaging requirements instead of tape and reel options.

Part Context

This part belongs to the SAM E70 family, designed for applications demanding high performance and rich peripheral sets. It shares the same core architecture with the SAM S70 but adds Ethernet capabilities. The Q21 designation typically indicates the highest memory configuration within the Q-series lineup.

Replacement Considerations

ATSAME70Q21A-CN serves as a direct alternative with identical specifications but different packaging format.
