The chip relies heavily on the LPC bus interface to interact with the system PCH. It handles standard I/O cycles, DMA transfers, and serialized interrupt streams. This alignment ensures compliance with standard ACPI requirements. 3. Keyboard Controller (KBC)
Table 10-7 details the VBAT (pin 128) monitoring. If voltage drops below 2.0V, the EC automatically resets the RTC registers. This is a common cause of "CMOS checksum error" on motherboards using this chip. Replace the backup battery before replacing the EC.
Handles system power states (S0-S5), including charging management and battery monitoring.
Extended range from -40°C to 105°C (TA), making it suitable for industrial and demanding commercial environments. wpce773la0dg datasheet pdf verified
Engineers should verify that the schematic diagram aligns with the specific motherboard revision, as custom firmware implementations are common. 4. WPCE773LA0DG Datasheet PDF Verified Sources

The verified datasheet explains the In-System Programming (ISP) procedure:
Major electronic component valuation indices track the chip at a 34% fake threat rating in open market procurement spaces. Counterfeits often involve recycled or rebranded components with altered date codes or completely non-functional inner silicon. This is a common cause of "CMOS checksum
Uses internal ADC (Analog-to-Digital Converters) to read analog thermal diodes placed near the CPU and GPU. Advanced Power Management
The part is Active , so you can purchase it from global electronic component distributors. Utsource , Bonchip , Mouser , or Digi-Key are reliable options. It is also widely available on eBay and AliExpress, but beware of used or counterfeit chips on those platforms.
No. The "773" has 64KB Flash; the "775" has 128KB Flash. While pin-compatible, the firmware is not interchangeable. The verified datasheet warns that cross-flashing will cause a hard lock.
