Overview
The ATSAMS70J20A-AN is a 32-bit microcontroller from the SAM S70 series, featuring an ARM Cortex-M7 core operating at 300MHz. It integrates 1MB of flash memory and 384KB of SRAM within a 64-LQFP package. The device supports a supply voltage range of 1.62V to 3.6V and operates between -40°C and 105°C. Key peripherals include five 12-bit ADC channels, one 12-bit DAC, USB, SPI, UART/USART, I2C, IrDA, LINbus, and SSC interfaces.
Feature Summary
- High-performance processing via ARM Cortex-M7 core with integrated FPU
- Integrated analog conversion capabilities including multiple ADC and DAC channels
- Comprehensive connectivity suite supporting industrial protocols like CAN, Ethernet, and USB
Applications
- Industrial automation controllers requiring high-speed processing
- Human-machine interface (HMI) displays with graphical rendering needs
- Smart metering systems utilizing advanced communication protocols
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the LQFP-64 configuration. Cross-reference part numbers with current datasheets to avoid obsolescence issues during production planning.
Selection Notes
Select this component when a balance of high computational power and moderate pin count is required. Compare against the ATSAME70 series for feature parity or the ATSAMS70J19A-AN for lower memory requirements. Consider the 64-pin constraint relative to total I/O needs before finalizing the design.
Part Context
This unit belongs to the SAM S70 family, designed for applications demanding robust performance in compact form factors. It shares architectural similarities with the E70 and V71 series but offers distinct peripheral configurations tailored for cost-sensitive industrial and consumer electronics markets.
Replacement Considerations
ATSAMS70J20A-MNT provides equivalent functionality in a 64-QFN package. ATSAMS70J19A-AN serves as a lower-memory alternative within the same LQFP-64 footprint.
