Product details
Overview
PCI4515AGHK from Texas Instruments is a dual-function PCI-to-CardBus bridge and IEEE 1394a-2000 OHCI-compliant single-port PHY/Link-layer controller in a 257-pin BGA package. It supports 100/200/400 Mbps FireWire data rates, PCI Local Bus Specification Revision 2.3, and PC Card Standard 8.1. It enables hot-pluggable CardBus socket control and integrated 1394 connectivity for portable computing platforms.
For engineers reviewing the PCI4515AGHK datasheet, PCI4515AGHK pinout, PCI4515AGHK application, or PCI4515AGHK equivalent, key selection considerations include its dual PCI function mapping (Function 0 for CardBus, Function 2 for 1394), 1.5-V core / 3.3-V I/O voltage operation, ACPI 2.0 compliance, and support for serialized IRQ, deep FIFO buffering, and physical write posting.
Technical Context
The PCI4515AGHK implements two independent PCI functions: Function 0 is an ExCA-compatible CardBus controller supporting 16-bit, CardBus, and custom interface PC Cards with internal hot-swap buffering; Function 2 is a fully IEEE Std 1394a-2000-compliant PHY/Link controller with cable port monitoring, connection debounce, and fly-by concatenation. Both functions share a common 32-bit PCI interface compliant with Revision 2.3.
It integrates advanced power management including PCI D0–D3 states, ultralow-power sleep mode, automatic device power-down during suspend, and support for Intel Mobile Power Guideline 2000. The controller uses advanced submicron CMOS technology and includes a 24.576-MHz crystal-based timing reference for 1394 transmit/receive synchronization at all three data rates.

Applications
| Mobile Notebook Expansion | Digital Video Capture Adapter |
|---|---|
Use Scenario: Adding CardBus-based peripherals (e.g., Wi-Fi, modem, SSD) and FireWire DV camcorder connectivity to thin-and-light notebooks. IC Role / Device Role / Timing Role: PCI4515AGHK serves as the unified bridge between the host PCI bus and both the CardBus socket and 1394 cable port - managing arbitration, power sequencing, and isochronous timing. Use Value: Eliminates need for discrete CardBus and 1394 controllers, reducing BOM cost and PCB area while maintaining full IEEE 1394a-2000 compliance at 400 Mbps. | Use Scenario: High-bandwidth video capture from FireWire-enabled DV, HDV, or DVCAM camcorders into Windows-based editing workstations. IC Role / Device Role / Timing Role: PCI4515AGHK acts as OHCI-compliant 1394 host controller with dual-buffered isochronous receive - synchronizing frame-aligned data streams to PCI bus timing. Use Value: Enables sustained 400-Mbps isochronous transfers with low jitter via deep FIFOs and physical write posting - critical for real-time uncompressed video ingestion. |
| Legacy PCMCIA Docking Station | Industrial Machine Vision Interface |
Use Scenario: Docking station providing simultaneous CardBus peripheral expansion (e.g., SCSI, Ethernet) and 1394 camera tethering for field service laptops. IC Role / Device Role / Timing Role: PCI4515AGHK manages concurrent PCI transactions across two independent functions - isolating CardBus I/O from 1394 streaming traffic. Use Value: Prevents bus contention through separate buffering and pipelined architecture - ensures deterministic response for both hot-plug events and real-time video capture. | Use Scenario: Embedded vision system using FireWire cameras in factory automation, where reliable hot-swap and deterministic power-down are required. IC Role / Device Role / Timing Role: PCI4515AGHK provides IEEE 1394a-2000 link-layer control with cable power presence monitoring and node power class signaling - enabling safe hot-insertion and system-level power management. Use Value: Supports extended suspend/resume cycles and ultralow-power sleep mode - extends operational uptime in fanless, thermally constrained enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-CardBus-and-1394 controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TIBB02312A | Single-function 1394a PHY-only device; no CardBus controller or PCI interface | Requires external PCI-to-CardBus bridge and OHCI host controller - increases component count and layout complexity | Only suitable when 1394 PHY functionality is needed separately from CardBus control |
| PCI4510A | Lacks IEEE 1394a-2000 enhancements (no fly-by concatenation, no arbitration acceleration); supports only 100/200 Mbps | Not interoperable with newer 400-Mbps FireWire devices or legacy DV components requiring extended resume signaling | Appropriate only for cost-sensitive designs targeting older 1394-1995/1394a-2000 baseline compliance without 400-Mbps or enhanced link reliability |
Compared with PCI4515AGHK, TIBB02312A requires full external controller integration, increasing design effort and board area, while PCI4510A omits critical 1394a-2000 features like fly-by concatenation and 400-Mbps support - limiting compatibility with modern FireWire peripherals and DV equipment.

FAQ
What is the primary function of the PCI4515AGHK?
The PCI4515AGHK is a dual-function PCI controller integrating a CardBus socket controller (Function 0) and an IEEE 1394a-2000 OHCI-compliant PHY/Link-layer controller (Function 2). It enables simultaneous high-speed peripheral expansion via CardBus and FireWire connectivity on portable computing platforms. Its architecture supports hot insertion, deep FIFO buffering, and full ACPI 2.0 power management - making it central to legacy mobile docking and video capture designs. The PCI4515AGHK delivers this functionality in a single 257-pin BGA package.
Is the PCI4515AGHK pin-compatible with the Intel 82365SL-DF controller?
Yes, the PCI4515AGHK's CardBus controller (Function 0) is register-compatible with the Intel 82365SL-DF ExCA controller, allowing reuse of existing BIOS and driver software. However, it is not physically pin-compatible due to differing package types - the 82365SL-DF uses PQFP packaging while the PCI4515AGHK uses a 257-pin MicroStar BGA. Board-level redesign is required for replacement, though software migration is simplified. The PCI4515AGHK extends functionality beyond the 82365SL-DF with integrated 1394 support and advanced power modes.
Does the PCI4515AGHK support 400-Mbps IEEE 1394 operation?
Yes, the PCI4515AGHK fully supports IEEE Std 1394a-2000 at 100 Mbps, 200 Mbps, and 400 Mbps data rates. Its PHY/Link layer implements all required encoding, resynchronization, and arbitration acceleration features for reliable 400-Mbps operation. The device includes TPBIAS terminal for proper cable biasing and monitors line conditions to maintain active connection integrity - ensuring interoperability with FireWire™ and i.LINK™ implementations that require full 1394a-2000 compliance. This capability is confirmed in the official TI SLLA241 datasheet for PCI4515AGHK.
What power management features does the PCI4515AGHK provide?
The PCI4515AGHK supports PCI D0–D3 power states, ACPI 2.0-compliant programming, and multiple low-power modes including automatic device power-down during suspend, inactive port power-down, and ultralow-power sleep mode. It complies with Intel Mobile Power Guideline 2000 and provides PME signaling per 1394 OHCI specification. These features allow system-level power optimization in battery-powered applications such as notebooks and docking stations. The PCI4515AGHK achieves this with a 1.5-V core powered by an internal regulator and 3.3-V I/O - minimizing external power supply complexity.
Why is the PCI4515AGHK marked as OBSOLETE, and is it still available for purchase?
The PCI4515AGHK is marked OBSOLETE by Texas Instruments per their packaging information addendum, indicating discontinued production. However, Aetrix Electronics maintains legacy inventory and offers traceable, tested units for ongoing production and repair programs. Supply support includes BOM continuity management and lifecycle coordination - enabling continued use in industrial maintenance, medical device servicing, and legacy video capture systems where redesign is impractical. While new designs should consider modern alternatives, the PCI4515AGHK remains viable for sustaining engineering needs.
