ATSAMS70J19A-MN

Overview

The ATSAMS70J19A-MN is a 32-bit microcontroller from the SAM S70 series, featuring an ARM Cortex-M7 core operating at 300MHz. It integrates 512KB of flash memory and 256KB of SRAM. The device includes five 12-bit ADC channels and one 12-bit DAC. It supports interfaces including I2C, SPI, UART/USART, USB, IrDA, and LINbus. Powered by 1.08V to 3.6V, it operates between -40°C and 105°C in a 64-QFN package with 44 I/O pins.

Feature Summary

• ARM Cortex-M7 processor with integrated DSP and FPU capabilities for high-performance computing
• Integrated analog peripherals including multiple 12-bit ADCs and a 12-bit DAC
• Comprehensive connectivity suite supporting USB, Ethernet-capable protocols, and standard serial buses

Applications

• Industrial automation control systems
• Human-machine interface (HMI) displays
• Medical equipment requiring precise analog signal processing
• Smart metering applications

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with required voltage levels and interface configurations. Cross-reference datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement specifications.

Selection Notes

Select this component when a balance of moderate memory capacity and high-speed processing is required. It is suitable for designs needing integrated analog conversion without external components. Compare against the ATSAME70 series if Ethernet MAC or CAN FD support is mandatory, as the SAM S70 variant may lack these specific peripheral sets.

Part Context

This part belongs to the SAM S70 family, designed for cost-sensitive applications compared to the E70 series. It shares the same core architecture but typically offers reduced peripheral counts such as fewer ADC channels and absence of Ethernet MAC. It serves as a streamlined alternative for embedded control tasks where maximum connectivity is not the primary constraint.

Replacement Considerations

ATSAMS70J19A-MNT: Identical functional specifications with tape-and-reel packaging instead of cut tape or tray options.
