ATSAMS70J19A-AN

Overview

The ATSAMS70J19A-AN is a 32-bit ARM Cortex-M7 microcontroller from the SAM S70 series, operating at a maximum clock frequency of 300 MHz. It features 512 kB of Flash program memory and 256 kB of SRAM data RAM. The device includes a 16 kB ROM block and supports a supply voltage range of 1.7 V to 3.6 V. It provides 44 general-purpose I/Os and integrates five 12-bit ADC channels and one 12-bit DAC. Interfaces include SPI, UART, USART, and USB. The component is housed in a 64-pin LQFP package with an operating temperature range of -40°C to +105°C.

Feature Summary

• High-performance processing via ARM Cortex-M7 core with integrated DSP instructions
• Integrated analog conversion capabilities including multiple 12-bit ADCs and a 12-bit DAC
• Support for serial communication protocols such as SPI, UART, USART, and USB

Applications

• Industrial control systems requiring high-speed processing
• Human-machine interface (HMI) displays
• Medical equipment applications
• Automotive infotainment systems

Procurement Notes

Verify the specific suffix AN corresponds to the LQFP-64 package variant when sourcing. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure design compatibility with the specified 1.7 V to 3.6 V supply voltage range and industrial temperature limits. Check for any recent product change notices affecting pinout or electrical characteristics.

Selection Notes

Select this model for designs necessitating the Cortex-M7 architecture within the SAM S70 family. Compare against ATSAME70J19B-AN if Ethernet connectivity is required, as the S70 series lacks built-in Ethernet controllers found in the E70 series. Evaluate memory requirements against the 512 kB Flash and 256 kB SRAM configuration to ensure sufficient resources for application firmware and runtime data.

Part Context

This component belongs to the SAM S70 series, which targets performance-oriented embedded applications. It shares the same core processor as the SAM E70 and V70 series but omits certain peripheral sets like Ethernet MACs to optimize cost and pin count for specific use cases. The J19 designation indicates the specific memory capacity and package configuration within the broader S70 product line.

Replacement Considerations

ATSAMS70J19A-MNT offers identical functional specifications in a 64-QFN package.
