ATSAMS70Q19A-ANT

Overview

The ATSAMS70Q19A-ANT is an ARM Cortex-M7 microcontroller from the SAM S70 series, packaged in a 144-pin LQFP with tape-and-reel delivery. It features a 32-bit architecture operating at up to 300 MHz, equipped with 512 kB of Flash memory and 256 kB of SRAM. The device includes 114 I/O lines, 24-channel 12-bit ADCs, and dual 12-bit DACs. Supported interfaces include SPI, UART, USART, USB, CAN, Ethernet, I2C, QSPI, MMC/SD/SDIO, LINbus, IrDA, EBI/EMI, and I2S. It operates within a voltage range of 1.7 V to 3.6 V and supports temperatures from -40°C to +105°C.

Feature Summary

• High-performance processing via ARM Cortex-M7 core running at 300 MHz
• Integrated analog conversion capabilities with 24-channel 12-bit ADCs and dual 12-bit DACs
• Comprehensive connectivity suite including Ethernet, USB, CAN, and multiple serial protocols
• Flexible external memory interface support for expanded storage or peripheral expansion

Applications

• Industrial automation controllers requiring high-speed processing and robust communication
• Human-machine interface (HMI) displays utilizing LCD/TFT drivers and touch control
• Medical equipment needing precise analog signal acquisition and digital control
• Smart metering systems integrating energy measurement and secure data transmission

Procurement Notes

Verify the specific suffix 'ANT' confirms the tape-and-reel packaging format rather than tray distribution. Confirm the exact pinout and electrical characteristics against the official Microchip datasheet for the SAM S70 family. Ensure compatibility with required operating voltages and temperature ranges for the target application environment before finalizing procurement.

Selection Notes

Select this component when a balance of high computational power and extensive peripheral integration is required in a surface-mount package. The 144-pin LQFP offers significant I/O availability compared to smaller packages while maintaining manageable board space. Consider the 512 kB Flash capacity for complex firmware requirements and the 300 MHz speed for real-time control tasks involving multiple simultaneous peripherals.

Part Context

This part belongs to the SAM S70 series, designed for applications demanding high performance and rich connectivity. It shares architectural similarities with the SAM E70 and SAM V70 families but is optimized for cost-effective industrial and consumer solutions. The device integrates advanced security features and low-power modes suitable for battery-operated or always-on systems.

Replacement Considerations

ATSAMS70Q19A-AN serves as the tray-packaged equivalent with identical electrical specifications. ATSAME70Q19A-CN provides the same functionality in a BGA package. Cross-family replacements like ATSAMD71 require software adaptation due to peripheral differences.
