Product details
Overview
PCI1450GJG from Texas Instruments is a dual-slot PC Card controller IC bridging 32-bit PCI bus to 16-bit PC Card and 32-bit CardBus interfaces. It supports hot insertion/removal, 132 MB/s burst transfers, ACPI 1.0 and PCI 2.1/2.2 compliance, and integrated Zoomed Video (ZV) path with 23 dedicated pins. Used in notebook/desktop add-in cards for legacy expansion.
For engineers reviewing the PCI1450GJG datasheet, PCI1450GJG pinout, PCI1450GJG application, or PCI1450GJG equivalent, key selection considerations include ExCA register compatibility with Intel 82365SL-DF, dual-socket power management (D3 cold wake-up), programmable interrupt routing (4 modes), ZV signal buffering, and 257-pin Micro-Star BGA package mechanical constraints.
Technical Context
The PCI1450GJG implements a PCI-to-CardBus bridge with two independent socket controllers, each supporting full 32-bit PCI cycles for 8-/16-/32-bit card access. Its pipeline architecture enables sustained bursting, while internal buffering isolates card signals for hot-swap safety.
It integrates a programmable interrupt subsystem with 8 IRQMUX outputs (configurable to 15 ISA IRQs), four GPIOs, and serial EEPROM interface for subsystem ID loading. The ZV path operates at pixel clock rates up to 27 MHz with dedicated PCLK, SCLK, LRCLK, SDATA, and sync signals (HREF/VSYNC).

Equivalent & Alternatives
The following parts are listed as comparable options for similar PC Card controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the primary function of the PCI1450GJG in a system architecture?
The PCI1450GJG serves as a PCI-to-CardBus bridge IC, enabling host systems with a 32-bit PCI bus to interface with two independent PC Card sockets-supporting both legacy 16-bit PC Cards and 32-bit CardBus devices. It handles protocol translation, power management, interrupt routing, and Zoomed Video signal buffering, making it essential for notebook expansion cards and docking stations. The PCI1450GJG integrates all necessary logic to eliminate external glue components in compliant designs.
Does the PCI1450GJG support hot insertion and removal of PC Cards?
Yes, the PCI1450GJG fully supports hot insertion and removal through internal signal buffering, advanced noise immunity (90 µs on card detect lines), and robust power-switch control via its 3-line serial interface to TI TPS2206. All card signals are isolated during insertion/removal events, and the device maintains stable register state during transitions between D0 and D3 power states. This ensures reliable operation in portable systems where users frequently swap modems, network adapters, or storage cards.
How does the Zoomed Video (ZV) interface of the PCI1450GJG differ from standard video I/O?
The PCI1450GJG's ZV interface provides a dedicated, internally buffered 23-pin path-including PCLK, SCLK, LRCLK, SDATA, HREF, VSYNC, and YUV/UV pixel buses-that connects directly to VGA controllers without external drivers or level shifters. Unlike generic video I/O, this path meets CardBus loading specifications, guarantees timing compliance, and offloads pixel data handling from the CPU via DMA. The PCI1450GJG manages ZV power domains separately, enabling low-latency video streaming in medical and industrial imaging applications.
Is the PCI1450GJG pin-compatible with the Intel 82365SL-DF controller?
The PCI1450GJG is ExCA register-compatible with the Intel 82365SL-DF, meaning software drivers and configuration logic can be reused-but it is not pin-compatible due to architectural differences: the PCI1450GJG uses a 257-pin Micro-Star BGA package with integrated ZV signals and dual-socket control, whereas the 82365SL-DF is a 128-pin PQFP device supporting only single-socket 16-bit PC Cards. Hardware redesign is required, though firmware migration is simplified by register mapping alignment.
What power management features does the PCI1450GJG implement per ACPI 1.0 and PCI specifications?
The PCI1450GJG implements full ACPI 1.0 and PCI Power Management Specification compliance, including D0–D3cold states, PME wake-up from D3cold via RI_OUT/PME pin, SUSPEND signaling, CLKRUN-driven clock gating, and hardware-assisted D3 entry/exit sequencing. It supports PCI bus lock (LOCK), distributed DMA for low-CPU wake events, and programmable D3 status reporting. These features allow host OS power managers to coordinate deep sleep states across PC Cards and the bridge itself-critical for battery life in mobile platforms using the PCI1450GJG.
