ATSAME70N19B-CNT

Overview

The ATSAME70N19B-CNT is a Microchip Technology microcontroller from the SAM E70 series, featuring an ARM Cortex-M7 core operating at 300 MHz. It integrates 512 KB of Flash memory and 256 KB of SRAM within a 100-pin LQFP package. The device supports a supply voltage range of 1.7 V to 3.6 V and includes 75 I/O pins with 12-bit ADC resolution.

Feature Summary

• High-performance processing via ARM Cortex-M7 architecture
• Integrated analog front-end capabilities with 12-bit conversion
• Flexible connectivity through multiple communication interfaces

Applications

• Industrial motor control systems
• Advanced human-machine interface (HMI) panels
• Complex embedded automation controllers

Procurement Notes

Verify the specific suffix CNT against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing design-in tools such as Atmel-ICE or SAMV71-XULT for development purposes. Cross-reference datasheet revisions to validate pinout and electrical characteristics prior to final procurement.

Selection Notes

Select this component when a balance of moderate I/O count and high-speed processing is required. It serves as a suitable alternative to higher-pin-count variants like the Q-series for cost-sensitive applications while maintaining the same core performance level found in the SAM E70 family.

Part Context

This part belongs to the SAM E70 family of 32-bit microcontrollers designed for demanding industrial and commercial applications. It shares architectural similarities with the S70 and V70 series but focuses on standard connectivity options without specialized automotive or Ethernet AVB features.

Replacement Considerations

Compatible substitutes include other SAM E70 variants such as ATSAME70J19B or ATSAME70Q19A, provided pin counts and peripheral requirements align with the target application design constraints.
