ATSAME70N20B-ANT

Overview

The ATSAME70N20B-ANT is a 32-bit microcontroller based on the ARM Cortex-M7 core, operating at a maximum frequency of 300 MHz. It features 1 MB of Flash memory and 384 kB of SRAM. The device includes ten 12-bit ADC channels and two 12-bit DAC channels. It supports multiple communication interfaces including Ethernet, CANbus, I2C, SPI, UART/USART, USB, and QSPI. Powered by a voltage range of 1.7 V to 3.6 V, it is housed in a 100-LQFP package with an operating temperature range of -40°C to +105°C.

Feature Summary

• High-performance processing via ARM Cortex-M7 core running up to 300 MHz
• Integrated connectivity supporting Ethernet, USB, and various serial protocols
• On-chip analog conversion capabilities with multiple ADC and DAC channels

Applications

• Industrial motor control systems
• Human-machine interface (HMI) displays
• Medical equipment requiring high-speed data acquisition
• Automotive infotainment and instrument clusters

Procurement Notes

Verify the specific suffix 'ANT' corresponds to the tape and reel packaging configuration as indicated by distributor listings. Confirm that the component meets RoHS3 compliance requirements for your manufacturing process. Ensure the selected variant matches the required pin count and package dimensions for your PCB layout design.

Selection Notes

Select this model when a balance of high computational power and extensive peripheral integration is required within a 100-pin footprint. Consider the ATSAME70N20A-AN if tray packaging is preferred over reel packaging, noting that the core functionality remains identical. Evaluate the ATSAME70J19B-AN if a smaller 64-pin package suffices for the application constraints.

Part Context

This component belongs to the Microchip SAM E70 family, designed for applications demanding robust performance and rich connectivity. The series integrates advanced peripherals such as LCD controllers and cryptographic accelerators alongside the Cortex-M7 processor, targeting complex embedded solutions across industrial and automotive sectors.

Replacement Considerations

ATSAME70N20A-AN serves as a direct functional substitute with identical specifications, differing primarily in packaging format.
