- Integrated analog conversion capabilities including multiple 12-bit ADCs and DACs
- Comprehensive peripheral set supporting diverse communication standards and data storage protocols
Applications
- Industrial automation control systems
- Human-machine interface displays
- Medical equipment controllers
- Automotive infotainment units
Procurement Notes
Verify the specific suffix CN against official Microchip documentation to confirm regional compliance or material specifications. Confirm the 100-TFBGA footprint matches your PCB design constraints. Ensure the 1.08V to 3.6V supply range aligns with your power architecture. Cross-reference the datasheet revision date for any errata updates affecting pinout or electrical characteristics.
Selection Notes
Select this component when high computational throughput is required alongside substantial onboard memory. The TFBGA package suits dense board layouts but requires specialized surface-mount assembly. Compare against other SAM S70 variants if different memory sizes or package types like LQFP are preferred. Verify that the internal oscillator meets timing accuracy requirements without external crystals.
Part Context
This part belongs to the SAM S70 family, designed for applications demanding advanced graphics and high-speed processing. It shares architectural similarities with the SAM E70 and V70 families but offers specific memory and peripheral configurations tailored for cost-sensitive yet performance-critical embedded solutions.
Replacement Considerations
ATSAMS70N20B-ANT: Different package (LQFP-100) and tape/reel format. ATSAMS70N19A-CN: Lower memory capacity (512KB Flash, 256KB SRAM). ATSAMS70N21B-CN: Higher memory capacity (2MB Flash).
