ATSAMS70J20A-MNT

Overview

The ATSAMS70J20A-MNT is a 32-bit microcontroller based on the ARM Cortex-M7 core, operating at a maximum frequency of 300 MHz. It features 1 MB of in-system programmable Flash memory and 384 KB of SRAM. The device includes an internal oscillator and supports a supply voltage range of 1.08 V to 3.6 V. It provides 44 I/O pins and integrates five 12-bit ADC channels and one 12-bit DAC channel. Connectivity options include I2C, IrDA, LINbus, SPI, SSC, UART/USART, and USB interfaces. The component is housed in a 64-QFN (9x9 mm) package with exposed pad and operates within a temperature range of -40°C to +105°C.

Feature Summary

• High-performance processing via ARM Cortex-M7 core with integrated DSP and FPU capabilities
• Integrated analog conversion subsystem featuring multiple 12-bit ADCs and a 12-bit DAC
• Comprehensive peripheral set including DMA, PWM, watchdog timer, and power-on reset
• Support for diverse communication protocols such as USB, SPI, I2C, and UART

Applications

• Industrial control systems requiring high-speed processing
• Medical devices utilizing analog signal acquisition
• Automotive applications supporting LINbus communication
• Consumer electronics with USB connectivity requirements

Procurement Notes

Verify the specific suffix MNT to confirm the 64-QFN package type and tape-and-reel shipping configuration. Ensure compatibility with the required 1.08 V to 3.6 V supply voltage range for your target application. Confirm that the 44 available I/O pins meet the interface count needs. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this model when 1 MB of Flash and 384 KB of SRAM are sufficient for the application firmware and data storage. Choose this variant over other SAM S70 members if the 64-pin QFN footprint is preferred for space-constrained designs. Consider the specific peripheral mix, particularly the five ADC channels and single DAC, against alternative pin counts like the ATSAMS70N series if more general-purpose I/O is needed.

Part Context

This component belongs to the Microchip SAM S70 family, which utilizes the ARM Cortex-M7 architecture. The family is designed for applications demanding high performance and rich connectivity. The SAM S70 series shares common architectural features with the SAM E70 and SAM V70 families, differing primarily in memory sizes, package options, and peripheral availability tailored for specific market segments.

Replacement Considerations

The ATSAMS70J20A-ANT serves as a tray-packaged alternative with identical electrical specifications. For reduced memory configurations, the ATSAMS70J19A-MNT offers 512 kB Flash and 256 kB SRAM in the same package.
