Component Identity

The YINGHUA AVR64DB64-EPT is a 64-pin microcontroller in a TQFP package for embedded control tasks. Engineers select it when a design needs 64 KB of flash and the AVR instruction set in a compact surface-mount footprint. The part is stocked new and ready for production or prototype assembly.

Fit and Alternatives

This device suits developers building single-chip control boards, sensor interfaces or low-power state machines that fit the 64-pin pinout. It is not for buyers who need more I/O lines, larger program memory or a different package style such as BGA or QFN. Projects requiring integrated analogue peripherals beyond the standard AVR set should evaluate other families.

Deciding Specification

The 64-TQFP package fixes the board layout and the available pin count for every interface. Verify that the 64 pins provide enough GPIO, communication and power connections for the target schematic before committing to this part number. The 2026 listing date confirms current manufacturer availability.

Questions about this item

Does the 64-TQFP package need a specific PCB footprint?

The 64-TQFP package requires a matching 64-pin PCB footprint with correct pad pitch and dimensions for surface-mount soldering.

What is the critical step when hand-soldering the 64-TQFP IC?

Align all 64 pins precisely before applying heat; misalignment on the fine-pitch leads is the step most often done incorrectly.

When should the AVR64DB64-EPT be replaced in a design?

Replace the device if it fails functional testing, shows physical damage, or no longer meets the firmware requirements after the 2026 listing date.
