Overview
The ATSAMS70J19A-ANT is a 32-bit microcontroller based on the ARM Cortex-M7 core, operating at a maximum frequency of 300MHz. It features 512KB of flash memory and 256KB of SRAM. The device includes five 12-bit ADC channels and one 12-bit DAC. It supports interfaces such as SPI, UART/USART, and USB. Powered by a voltage range of 1.7V to 3.6V, it operates between -40°C and +105°C in a 64-LQFP package.
Feature Summary
- High-performance processing via ARM Cortex-M7 core with FPU
- Integrated analog conversion capabilities including multiple ADCs and a DAC
- On-chip connectivity supporting standard serial communication protocols
Applications
- Industrial control systems requiring high-speed processing
- Medical devices utilizing analog signal acquisition
- Consumer electronics with USB interface requirements
Procurement Notes
Verify the specific suffix 'ANT' corresponds to the tape and reel packaging configuration when ordering. Confirm that the 64-LQFP footprint matches the target PCB design. Ensure the voltage supply range aligns with system power rails. Check for any recent product change notices regarding pinout or electrical characteristics updates from the manufacturer.
Selection Notes
Select this component when a balance of moderate memory capacity and high clock speed is required within a compact 64-pin form factor. It serves as a suitable alternative to larger packages if I/O count constraints exist. Consider the internal oscillator accuracy if external crystal precision is critical for timing-sensitive applications.
Part Context
This part belongs to the SAM S70 series, designed for applications needing robust performance without the complexity of higher-end models. It shares architectural similarities with the ATSAME70 series but targets specific market segments with tailored peripheral sets. The J19 designation indicates specific memory and package combinations within the family.
Replacement Considerations
ATSAMS70J19A-MNT offers identical electrical specifications in a QFN package. ATSAMS70J21B-ANT provides increased memory resources in the same LQFP-64 package.
