Highly integrated controller with embedded microcontrollers designed for fast peripheral management. Keyboard Controller: Supports matrix keyboard scanning.
Handles system power states (S0-S5), including charging management and battery monitoring.
The is a highly integrated Embedded Controller (EC) developed by Nuvoton Technology. It is primarily used in laptop motherboards, netbooks, and industrial computing platforms. This micro-controller manages low-level system tasks that the main CPU cannot handle efficiently when asleep or booting up.
Integrated with chipsets like the Intel Cantiga-GM and ICH9M. Wistron Project Codes: Frequently appeared in designs such as the (Project 91.4CQ01.001). Verified Datasheet Resources
Getting a is a ritual of good engineering practice. While the PDF may be harder to find than a standard 555 timer chip, the effort is always worth it. By going directly to Nuvoton, using a datasheet aggregator, or locating the official laptop schematics, you can uncover the precise electrical and physical characteristics of the chip. This empowers you to successfully repair a dead motherboard, design a compatible system, or simply expand your technical knowledge. wpce773la0dg datasheet pdf verified
(formerly part of Winbond). It is a vital component in laptop motherboards, serving as the bridge between the system's hardware and its firmware. Commonly found in high-performance machines like the Apple MacBook Pro (A1286) and various
Use an oscilloscope to verify if the 33MHz LPC clock is oscillating.
Pins designed to manage the startup sequence of the motherboard, including sending signals to turn on the CPU VRM (Voltage Regulator Module).
The integrated keyboard matrix controller supports standard matrix configurations (typically up to 16x8 matrix scanning). It also handles legacy PS/2 devices, mouse interfaces, and specialized hotkey mappings found on modern portable computers. 4.

| Specification | Details | | :--- | :--- | | | Winbond Electronics / Nuvoton Technology | | Part Number | WPCE773LA0DG | | Function | Multi-Controller / Embedded Controller (EC) / Super I/O | | Core Logic | KBC (Keyboard Controller) & Embedded Controller | | Package Type | QFP (Quad Flat Package) / TQFP-128 | | Supply Voltage (VDD) | 2.7V to 5.5V |
When looking for a verified datasheet for the WPCE773LA0DG, ensure the document covers the specific suffix variant. Suffix variations often dictate internal memory differences, package refinements, or specific logic level tolerances.
Embedded Controllers like the WPCE773LA0DG are the first integrated circuits to boot when power is applied to a motherboard, long before the primary CPU or GPU initializes. They run specialized internal firmware designed to manage baseline physical behaviors:
Finding a "verified" datasheet can be difficult as these are often proprietary to the notebook design. However, general data can be accessed through major electronic component distributors and archive sites. Integrated with chipsets like the Intel Cantiga-GM and ICH9M
Hope this saves someone else the headache of searching!
Section 5.3 specifies ICC(max) = 180 mA at 25 MHz. If the chip exceeds 60°C (140°F) without load, it is likely shorted (VDDC to GND). The datasheet provides a thermal resistance of 20°C/W.
Before diving into the datasheet, you must understand the role of this IC. The WPCE773LA0DG is a highly integrated with the following core architecture:
