ATSAMS70J20B-MNT

Overview

The ATSAMS70J20B-MNT is a Microchip Technology ARM microcontroller from the SAM S70 series, featuring an ARM Cortex-M7 core operating at a maximum clock frequency of 300 MHz. It integrates 1 MB of flash program memory and 384 kB of SRAM data RAM within a 64-pin VQFN package. The device supports a supply voltage range of 1.7 V to 3.6 V and includes 44 general-purpose I/Os. Peripheral interfaces include SPI, UART/USART, and USB. It features a 12-bit ADC with 5 channels and a 12-bit DAC.

Feature Summary

• High-performance processing capability via ARM Cortex-M7 core architecture
• Integrated analog signal conversion with 12-bit resolution for both input and output
• Support for multiple serial communication protocols including USB and USART

Applications

• Industrial control systems requiring high-speed processing
• Medical devices utilizing analog-to-digital signal acquisition
• Automotive infotainment or instrument clusters using USB connectivity

Procurement Notes

Verify the specific suffix 'MNT' against the official datasheet to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this model when a balance of moderate pin count (44 I/O) and substantial memory (1 MB Flash, 384 kB SRAM) is required in a compact surface-mount package. It is suitable for applications needing USB connectivity and limited analog inputs compared to larger BGA variants. Consider the VQFN-64 footprint constraints during PCB layout design.

Part Context

This component belongs to the SAM S70 family of 32-bit microcontrollers designed for applications demanding high performance and rich peripheral sets. The J-series variant typically offers a reduced pin count compared to Q-series counterparts while maintaining the same core performance and memory capacity. It shares architectural similarities with the SAM E70 and SAM V70 families.

Replacement Considerations

ATSAMS70J20A-MNT: Similar memory and core specifications but may differ in interface support or manufacturing revision. ATSAMS70N20A-CN: Offers higher I/O count (75 pins) in a BGA-100 package, requiring significant PCB redesign.
