This chip is most frequently encountered in . It is a staple in many Apple MacBook models , such as the MacBook Air A1304 and MacBook Pro A1286/A1278 , where it acts as the primary I/O controller. In these systems, a failure in the WPCE773LA0DG often leads to power-on issues, keyboard/trackpad failure, or fan control problems. Purchasing and Availability (2021 Update)
Offers a direct link to the WPCE773LA0DG Datasheet (PDF) and current inventory levels.
Offers a downloadable PDF focusing on manufacturer information and inventory status.
The is a highly integrated Input/Output (I/O) controller chip, typically classified within the processors or microcontrollers category. While direct "2021" manufacturer-issued datasheet PDFs are scarce due to its legacy status, technical documentation and procurement options remain available through specialized distributors. Technical Specifications
The Winbond WPCE773LA0DG is a highly integrated, low-power, and feature-rich microcontroller unit (MCU) designed for a wide range of applications, including industrial control, consumer electronics, and Internet of Things (IoT) devices. As a leading provider of semiconductor solutions, Winbond has been delivering high-quality products to meet the growing demands of the electronics industry. In this article, we will provide an in-depth look at the WPCE773LA0DG MCU, its features, and benefits, as well as guide you on how to download its datasheet in PDF format.
Supply houses such as Ariat Tech's WPCE773LAODG Catalog offer standardized packaging data and basic electrical parameters.
Official datasheets from Winbond for this specific generation of chips are tightly controlled. To find schemas, pin layouts, or functional block diagrams, engineers often rely on alternative documentation methods:
The definitive documentation for this IC is found through specialized database providers. Because it is an older product, finding active listings on public manufacturer portals can be difficult.
Signals like RSMRST# (Resume Reset), PWRBTN# (Power Button), and SUSB# / SUSC# regulate the power-up sequence. The EC must receive the power button trigger and release RSMRST# to inform the PCH that standby power is stable. Common Faults and Troubleshooting
To verify that the chip is getting stable core voltage power.
If you are unable to find the datasheet on the Winbond website, you can try the following alternative sources:
To help narrow down the technical information for your repair or design project, tell me:
The fan controller now includes an auto-spinup algorithm. Table 12-3 in the 2021 PDF provides recommended register values for 4-wire PWM fans – values that were omitted in the 2019 release.
