WPCE773LA0DG is an Embedded Controller (EC) chip, primarily used as a Super I/O (SIO) wpce773la0dg datasheet pdf better

controller in laptop and industrial motherboards. Originally developed by Winbond Electronics , this product line was later transitioned to Nuvoton Technology Corporation after Nuvoton was spun off from Winbond. ariat-tech.com Core Specifications Manufacturer: Nuvoton Technology Corporation (formerly Winbond). Package Type: (128-pin Quad Flat Package). Operating Temperature: Extended range of -40°C to 105°C cap T sub cap A ), making it suitable for industrial environments.

Processors / Microcontrollers (specifically Super I/O / Embedded Controllers). Typical Applications:

Found in laptop motherboards (e.g., Apple MacBook Pro Mid-2010 models, Wistron schematics) for managing legacy ports, power sequencing, and keyboard control. ariat-tech.com Key Functions As a Super I/O chip, the WPCE773LA0DG typically manages: Legacy I/O Support:

Serial and parallel ports, keyboard controller (KBC), and PS/2 mouse interfaces. Hardware Monitoring: Voltage, temperature, and fan speed control. General Purpose I/O (GPIO): Multiple configurable pins for system-specific logic. Firmware Interface:

Often works alongside SPI BIOS chips (typically 4MB) to manage boot sequences. Datasheet and Procurement Resources Poorly scanned datasheets ruin these

Q: Is the WPCE773LA0DG the same as the WPCE775LA0DG? A: No. The 775 variant has more GPIO pins and a larger embedded flash (256KB vs. 128KB). Using the wrong datasheet will lead to register mapping errors.

Q: Can I use a WPCE773LA0DG in a new design in 2025? A: Unlikely – it’s end-of-life for new consumer products. But for repairs or legacy industrial systems, it’s still available. Check distributor stock on Mouser or DigiKey. If your datasheet’s timing diagrams are unreadable, you

Q: My datasheet says “Preliminary” – is that bad? A: Yes. A preliminary datasheet may have incorrect pinouts or unimplemented features. Look for “Final” or “Rev 1.x” watermarks.

Q: Where’s the cheapest place to buy this chip? A: Aliexpress and Utsource sell pulled chips, but they may be counterfeit. A “better” datasheet includes die markings – use those to verify authenticity.
