ATSAME70N21A-ANT

Overview

The ATSAME70N21A-ANT is a Microchip Technology microcontroller from the SAM E70 series, featuring an ARM Cortex-M7 core operating at 300 MHz. It provides 2 MB of flash memory and 384 KB of SRAM within a 100-pin LQFP package. The device supports a 32-bit data bus width and includes integrated peripherals such as Ethernet, USB, CANbus, SPI, UART/USART, I2C, QSPI, MMC/SD/SDIO, LINbus, IrDA, DMA, I2S, PWM, and watchdog timer. It offers 10-channel 12-bit ADCs and two 12-bit DACs. Operating voltage ranges from 1.62 V to 3.6 V, with a functional range of 1.7 V to 3.6 V. The component operates between -40°C and +105°C and is supplied in tape and reel packaging.

Feature Summary

• High-performance processing via ARM Cortex-M7 core running at 300 MHz
• Integrated connectivity interfaces including Ethernet, USB, and CANbus
• On-chip analog conversion with ten 12-bit ADC channels and dual 12-bit DACs

Applications

• Industrial motor control systems
• Human-machine interface (HMI) displays
• Smart metering applications

Procurement Notes

Verify the specific suffix 'ANT' confirms the tape and reel packaging format required for automated assembly processes. Confirm that the 100-LQFP footprint matches the target PCB design. Ensure the 1.62V to 3.6V supply voltage requirements are met by the system power architecture. Validate that the industrial temperature range of -40°C to +105°C aligns with environmental specifications.

Selection Notes

Select this component when high computational throughput is required alongside extensive peripheral integration. The 2 MB flash capacity supports complex firmware and large graphics buffers. The inclusion of dedicated hardware accelerators and multiple communication interfaces reduces external component count. Consider the 100-pin package density for board space constraints compared to smaller variants in the same family.

Part Context

This part belongs to the SAM E70 family of 32-bit microcontrollers designed for demanding embedded applications. It shares the Cortex-M7 architecture with other models like the ATSAME70N20A but distinguishes itself through increased flash storage. The series targets markets requiring robust connectivity and real-time processing capabilities without relying on external controllers.

Replacement Considerations

ATSAME70N20A-AN: Offers identical core performance and peripherals but with reduced 1 MB flash memory. ATSAMS70N21A-ANT: Shares the same 2 MB flash and 384 KB RAM configuration but utilizes a TFBGA-100 package instead of LQFP.
