Overview
The W83L603G is an I/O expander manufactured by Nuvoton Technology Corporation. It provides eight general-purpose input/output (GPIO) pins accessible via SMBus and I2C serial interfaces. The device operates at a supply voltage of 3.3V and is designed for surface-mount installation in SOP-14 packages. It supports RoHS compliance standards and functions within a minimum operating temperature of 0°C.
Feature Summary
- Provides eight configurable GPIO pins for system expansion
- Supports SMBus and I2C serial communication protocols
- Operates on a 3.3V power supply rail
- Available in compact SOP-14 surface-mount packaging
Applications
- General-purpose I/O expansion in embedded systems
- SMBus-based peripheral control interfaces
- I2C bus extension for low-pin-count microcontrollers
Procurement Notes
Verify current production status directly with the manufacturer, as lifecycle information may be subject to change. Confirm availability through authorized distributors or official channels before initiating procurement processes. Ensure compatibility with existing system voltage levels and interface requirements.
Selection Notes
Select this component when eight additional digital I/O lines are required for SMBus or I2C systems. Verify that the target application environment maintains a stable 3.3V supply. Ensure the PCB layout accommodates the SOP-14 package dimensions and thermal requirements for surface-mount assembly.
Part Context
This part belongs to the category of interface ICs specifically designed as I/O expanders. It serves to bridge communication between host controllers and peripheral devices requiring additional digital signals. The device integrates standard serial interface logic to facilitate easy integration into existing SMBus or I2C architectures without complex hardware modifications.
Replacement Considerations
Consult official documentation for verified substitute part numbers. Cross-referencing requires matching pinout configurations, voltage specifications, and interface protocol support to ensure functional equivalence in the target application.
