Procurement Notes

Verify the specific suffix CFNT confirms the tape-and-reel packaging format, which differs from the tray-packaged CN variant. Ensure compatibility with reflow soldering profiles specified for the UFBGA-144 package. Confirm moisture sensitivity level handling requirements during storage and assembly. Cross-reference the latest datasheet revision for any errata or design changes affecting pinout or electrical characteristics.

Selection Notes

Select this component when a balance of high computational performance and rich peripheral integration is required. The 512 kB Flash and 256 kB SRAM suit complex firmware applications. Consider the UFBGA package for space-constrained designs where surface mount technology is preferred. Evaluate power consumption specifications against system battery life requirements if applicable.

Part Context

This part belongs to the SAM S70 family, which targets high-performance embedded applications. It shares architectural similarities with the SAM E70 and SAM V70 families but may differ in specific peripheral sets or connectivity options. The Q19 designation typically indicates the specific memory configuration within the series.

FAQ

What is the difference between the ATSAMS70Q19A-CN and ATSAMS70Q19A-CFNT?

The primary difference is the packaging format. The CN suffix denotes a Tray package, while the CFNT suffix indicates a Tape & Reel package suitable for automated surface-mount assembly.

Does the ATSAMS70Q19A-CFNT support Ethernet connectivity?

Yes, the SAM S70 family generally includes Ethernet MAC peripherals. However, specific availability depends on the exact silicon revision and datasheet documentation for this specific part number.
