ATSAMS70J19B-ANT

Overview

The ATSAMS70J19B-ANT is a 32-bit microcontroller from the Microchip SAM S70 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 144-pin LQFP package. The device supports a supply voltage range of 1.7 V to 3.6 V and includes multiple communication interfaces such as SPI, UART, USART, USB, CAN-FD, Ethernet, I2C, and I2S. It also provides analog peripherals including five 12-bit ADC channels and one 12-bit DAC.

Feature Summary

• High-performance processing via ARM Cortex-M7 core with integrated DSP and FPU capabilities for complex control applications.
• Comprehensive connectivity suite supporting industrial protocols like CAN-FD and Ethernet alongside standard serial interfaces.
• Integrated analog front-end with high-resolution ADCs and DACs for precise signal acquisition and generation.

Applications

• Industrial automation controllers requiring robust real-time processing and deterministic communication.
• Human-machine interface (HMI) panels utilizing display controllers and touch screen inputs.
• Smart energy metering systems demanding high accuracy and secure data transmission.
• Medical equipment requiring reliable digital signal processing and isolated communication links.

Procurement Notes

Verify the specific suffix 'ANT' confirms the tape-and-reel packaging format rather than tray distribution. Confirm the 'B' revision status against the latest datasheet updates to ensure compatibility with required errata fixes. Check RoHS compliance documentation for current environmental standards. Validate pinout compatibility if replacing older revisions within the same family.

Selection Notes

Select this component when a balance of high-speed processing and extensive peripheral integration is required in a moderate pin-count package. Compare against the ATSAME70 series for similar performance but different feature sets or memory configurations. Consider the ATSAMS70N19B-ANT if a smaller 100-pin package is sufficient for the design constraints. Evaluate power consumption requirements against the 300 MHz maximum clock speed specifications.

Part Context

This part belongs to the SAM S70 family, designed for high-performance embedded applications. It shares architectural similarities with the SAM E70 and SAM V70 series but offers specific peripheral combinations tailored for industrial and automotive environments. The J variant typically denotes a specific pin count and package configuration within the broader S70 portfolio.
