Procurement Notes

Verify the specific suffix 'AN' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with design requirements for the TQFP-48 form factor. Confirm that the 1.62 V to 3.63 V supply range aligns with the target system power architecture. Check for any recent product change notifications regarding manufacturing sources or assembly locations.

Selection Notes

Select this part when a low-power 32-bit MCU with moderate memory capacity is required. The 16 kB Flash and 2 kB SRAM suit applications with constrained code size. The TQFP-48 package offers a balance of pin count and board space. Consider alternative SAMD20 variants if higher I/O counts or different package styles are needed.

Part Context

This component belongs to the Microchip SAM D20 family of microcontrollers. The family utilizes the ARM Cortex-M0+ architecture to deliver performance with low power consumption. Other members in this series vary by memory size, package type, and peripheral availability while sharing the same core processor technology.

Replacement Considerations

Consult official Microchip cross-reference tools for verified substitutes. Equivalent parts within the SAM D20 family may offer different memory sizes or packages. Verify pinout compatibility before replacing the component in existing designs.
