Datasheet Pdf Verified: Wpce773la0dg

Specified for an extended range of -40°C to 105°C (TA) , making it suitable for both commercial and industrial environments.

Offers a comprehensive technical summary and stock availability. The Datasheet Archive

Due to its wide temperature tolerance, it is used in ruggedized embedded systems.

The is an advanced I/O (Input/Output) controller chip, primarily manufactured by Winbond Electronics (often associated with Nuvoton Technology Corporation following the acquisition of Winbond’s Logic IC business). This component is a critical part of modern computing hardware, specifically found in laptop motherboards and mobile computing systems. Key Technical Specifications

A counterfeit or incomplete datasheet for this EC will not show the correct GPIO multiplexing or power-on sequence requirements, leading to bricked boards. wpce773la0dg datasheet pdf verified

Detailed LQFP128 (QFP) dimensions to ensure proper soldering.

Extended range of -40°C to 105°C (TA).

Tracking thermal sensors and fan speeds to prevent overheating. Legacy Port Support:

When all else fails, search for the for a laptop known to contain the chip. For example, the Acer Aspire 5810TG schematic explicitly lists the “KBC (Embedded Controller), SIO: WPCE773LA0DG ”. The schematic PDF is often a 40-page document that contains a full pinout for the chip. A schematic is not the chip’s datasheet, but it is an official diagram from the laptop manufacturer showing exactly how the chip is wired. This is often more useful than a bare datasheet for a technician. Specified for an extended range of -40°C to

As a "Super I/O" or "Multi-controller" chip, the WPCE773LA0DG serves several vital roles: Winbond WPCE773LA0DG 773LA0DG IO Controller Chip ICs

Pins such as LCLK (LPC Clock), LFRAME# , and LAD[3:0] carry multiplexed command, address, and data signals between the EC and the system hub.

: Verify that the 3.3V standby power rail successfully reaches the chip's power inputs. The is an advanced I/O (Input/Output) controller chip,

Use an oscilloscope to verify if the 33MHz LPC clock is oscillating.

For engineers and laptop repair professionals, the is a critical Embedded Controller (EC) and Super I/O (SIO) chip often found in laptop motherboards. Originally produced by Winbond and later part of the Nuvoton product line, this IC manages low-level system functions such as power sequencing, keyboard management, and thermal monitoring.
