PCI1450GJG

Controllers Overview

The Texas Instruments PCI1450GJG is a high-performance PC Card controller featuring a 32-bit PCI interface. It supports two independent PC Card sockets compliant with the 1997 PC Card Standard and PCI-to-CardBus Bridge specifications. The device operates with a 3.3-V core logic and universal PCI interfaces compatible with both 3.3-V and 5-V signaling environments. It enables mix-and-match configurations of 5-V/3.3-V PC Card16 cards and 3.3-V CardBus cards, supporting hot insertion and removal. The controller facilitates burst transfers up to 132 Mbyte/sec and includes an internally buffered zoomed video path.

Controllers Feature Summary

• Supports two independent PC Card sockets for simultaneous operation of 16-bit and CardBus cards
• Provides an internally buffered zoomed video (ZV) path to reduce design effort
• Features programmable interrupt subsystem with multiple signaling modes including Serial ISA/Serial PCI
• Includes four general-purpose I/O pins and dedicated pins for PCI CLKRUN and socket activity LEDs

Controllers Applications

• Bridging between PCI bus and PC Cards in notebook computers
• Bridging between PCI bus and PC Cards in desktop computers
• Systems requiring support for mixed 16-bit and 32-bit CardBus card implementations

Controllers Procurement Notes

Verify the specific GJG suffix indicates the 257-pin Micro-Star BGA package configuration. Confirm that the component matches the SCPS044 datasheet revision from September 1998. Ensure compatibility with the intended system's PCI signaling voltage levels and power management requirements before integration.

Controllers Selection Notes

Select this controller when designing systems requiring dual PC Card slots with full 32-bit PCI interface capabilities. It is suitable for applications needing integrated zoomed video support and flexible interrupt routing options. Consider the 257-pin BGA packaging constraints during PCB layout and thermal management planning.

Controllers Part Context

The PCI1450 is part of Texas Instruments' legacy PC Card controller family designed for PCI-based systems. It serves as a bridge between the host PCI bus and peripheral PC Card interfaces. The device is register-compatible with the Intel 82365SL-DF ExCA controller, facilitating migration and integration into existing architectures.
