The form factor is a Quad Flat Package . This means it is a square chip, with 32 pins on each of its four sides. It’s a surface-mount device, designed to be soldered flat onto the surface of a printed circuit board (PCB). The part number often contains embedded codes, such as “LA0DG,” that describe the specific silicon revision and package details.
Primarily found in laptop motherboards, such as the Wistron SJV50 (Acer Aspire 5738G) and early MacBook Air/Pro models (A1304, A1286). Functionality and Applications | Symptom | Verified Diagnosis | Action |
Features contextual search results that include block diagrams and power sequence information from laptop motherboard schematics (e.g., Wistron, JM41/JM51 designs). WPCE773LA0DG Datasheets - ariat-tech.com
This component is a (Super I/O) that often requires advanced soldering skills to replace. It is commonly found in laptop schematics alongside other power and logic components, such as the ISL62392 power IC. Market Availability Wpce773la0dg Datasheet Pdf Verified !!exclusive!!
The 128-pin LQFP package distributes its pins into logical groups. These groups manage everything from basic power delivery to advanced signaling.
If the Nuvoton website is proving difficult to navigate, check the inventory listings on or Digi-Key . Even if they don’t stock the WPCE773LA0DG, the product page for any Nuvoton EC chip (like the NPCE795LA0DX) will have a link to view the manufacturer’s datasheet on the Nuvoton site. A “Mouser Part Number” or “Datasheet” button on a component website usually links directly back to the manufacturer’s PDF.
