Overview
The SMSC LPC47B373QFP is a Super I/O controller housed in a 100-pin Quad Flat Package (QFP) with a 0.65 mm pitch. It operates on a 5 V supply (4.5–5.5 V range) and supports commercial temperature ranges from 0°C to 70°C. The device features an 8-bit external data bus, an 11-bit address bus, and ISA bus compatibility. Its maximum functional clock frequency is 14.32 MHz. Constructed using CMOS technology, it is designed for embedded system applications requiring integrated peripheral management.
Feature Summary
- Integrates multiple peripheral functions into a single chip for system control
- Supports ISA bus interface protocols for legacy compatibility
- Utilizes surface-mount QFP packaging for compact board integration
Applications
- Embedded computer systems
- Super I/O controller implementations
- LPC bus based hardware platforms
Procurement Notes
Verify the specific suffix or revision code against official SMSC documentation to confirm pinout and feature set accuracy. Ensure the procurement source provides genuine components with valid traceability. Confirm that the package type matches the required 100-pin QFP specification for your design. Check for any obsolescence notices or lifecycle status updates from the manufacturer before finalizing orders.
Selection Notes
Select this component when an ISA-compatible Super I/O solution is required for embedded architectures. It is suitable for designs needing integrated peripheral management within a 5 V logic environment. Consider the 100-pin QFP footprint constraints during PCB layout. Verify thermal requirements against the commercial grade operating range of 0°C to 70°C for your specific application environment.
Part Context
This part belongs to the SMSC LPC47 series of Super I/O controllers. These devices are designed to manage low-speed peripherals in PC and embedded systems. The LPC47B373 variant specifically targets applications requiring robust interface support and integrated control functions within a standard industrial form factor.
Replacement Considerations
Consult official SMSC cross-reference guides for verified substitutes. Generic equivalents may lack specific register compatibility or timing characteristics required by the host system.
