Winbond Wpce773la0dg Datasheet — Pdf Updated Download 2021
Whether you are designing a new embedded motherboard or maintaining an existing product line, always verify that you have the 2021 version (or newer) downloaded and archived locally. Do not rely on cached or third-party copies from 2018 or earlier unless you enjoy debugging phantom hardware faults.
It manages the multi-line matrix keyboard scanning layout, handles hardware-level debouncing, and transmits keystroke data directly to the host operating system via the LPC bus interface. 3. Thermal and Fan Management
The chip manages the matrix scanning of the laptop keyboard. It handles debouncing, ghost key prevention, and transmits scan codes to the host via the LPC bus.
The chip communicates with the Southbridge or PCH using these lines: Multiplexed command, address, and data lines. LFRAME#: Indicates the start of an LPC bus cycle. LCLK: LPC clock input (typically 33 MHz). 3. System Management Signals winbond wpce773la0dg datasheet pdf download 2021
The WPCE773LA0DG is a frequent point of failure in laptops due to its exposure to standby power rails and external ports. Symptoms of a Faulty Chip:
Winbond Electronics (Original) / Nuvoton Technology Corporation (Current). Part Category: Logic Integrated Circuit / Embedded Microcontroller. Package Type: (128-pin Quad Flat Package). Operating Temperature Range: cap T sub cap A ), making it suitable for industrial-grade applications. Production Status (as of 2021-2024):
Manages input from the laptop keyboard and touchpad. Whether you are designing a new embedded motherboard
Tracks voltage rails and protects components from over-voltage or over-temperature conditions.
The you are experiencing (e.g., no power, loop restarting) What voltage rails you have already measured
The embedded controller works closely with the main system SPI Flash BIOS memory chip (such as a Winbond 4MB or 8MB W25Q series). Corrupted firmware inside the SPI chip can look like a physically dead WPCE773LA0DG chip. Flashing the main BIOS or the dedicated EC ROM should always be attempted before desoldering hardware. The chip communicates with the Southbridge or PCH
Connects the EC directly to the PCH/Southbridge for bios data transfer.
