The Texas Instruments PCI1131PDV is a multifunction PCI-to-CardBus controller for mobile PC applications. It provides a single PCI bus interface bridge (card function), with a dual CardBus socket capable of supporting two Type II or one Type III CardBus cards. This IC is commonly used in laptops and other mobile computing devices. Functions: - Provides a PCI interface to connect to the system bus and a CardBus interface to interface with CardBus slots. - Supports two Type II or one Type III CardBus cards. - Manages data transfer between the PCI and CardBus interfaces. - Handles power management functions for the connected CardBus cards. Applications: The Texas Instruments PCI1131PDV is typically used in laptops and portable computing devices to enable the connection of CardBus peripheral cards. Some common applications include: - Expansion of I/O capabilities via CardBus cards (e.g., network adapters, sound cards). - Adding additional storage options (e.g., CardBus-based solid-state drives). - Enhancing multimedia capabilities (e.g., video capture cards). Alternative Components: - Texas Instruments PCI1130PDV: Similar functionality as the PCI1131PDV with minor differences. - OXCB950: CardBus controller IC from Oxford Semiconductor. Embedded Modules: The PCI1131PDV integrates various functions, making it a standalone solution for PCI-to-CardBus bridging in mobile applications. No specific embedded modules are typically associated with this IC. Related Q&A: 1. What are the main advantages of using the Texas Instruments PCI1131PDV in laptop designs? 2.
