YINGHUA AT91M55800A-33AU 176-LQFP semiconductor

AT91M55800A-33AU microcontroller

The AT91M55800A-33AU is a 176-pin LQFP microcontroller supplied new from YINGHUA. It targets engineers building embedded control systems that require this specific part number for production or repair. The component is classified as an IC semiconductor and carries the manufacturer highlights exactly as listed.

Drop-in replacement for existing AT91M55800A-33AU

This device serves as a direct replacement when the same AT91M55800A-33AU part is specified in a bill of materials or schematic. The jump is worth it when a project demands the exact 176-LQFP package and 33 MHz rating identified in the supplier data. No alternative part numbers or generations are referenced in the available facts.

176-LQFP package with 33 MHz operation

The 176-lead quad flat pack provides the pin count and footprint defined for this AT91M55800A variant. It comfortably handles designs laid out for this specific package and clock speed. Headroom ends where the application requires a different pin count, voltage range, or frequency not covered by the 33AU suffix.
