Product details
Overview
PCI4515AZHK 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 Revision 2.3, PC Card Standard 8.1, and ACPI 2.0 power management. It enables hot-pluggable CardBus socket control and high-throughput isochronous transfers in mobile docking stations.
For engineers reviewing the PCI4515AZHK datasheet, PCI4515AZHK pinout, PCI4515AZHK application, or PCI4515AZHK equivalent, key selection criteria include its dual PCI function mapping (Function 0 for CardBus, Function 2 for 1394), integrated PHY-link layer, 1.5-V core / 3.3-V I/O voltage domains, and support for serialized IRQ, deep FIFO buffering, and SBP-2–optimized physical data path.
Technical Context
The PCI4515AZHK implements two independent PCI functions: Function 0 is an ExCA-compatible CardBus controller supporting 16-bit, CardBus, and USB-custom PC Cards with internal hot-swap buffering and Intel 82365SL-DF register compatibility; Function 2 is a full IEEE 1394a-2000 PHY/Link controller with cable port monitoring, line condition sensing, and TPBIAS biasing.
It integrates advanced power management including PCI D0–D3 states, ultralow-power sleep mode, automatic device power-down during suspend, and PME signaling per 1394 Open Host Controller Interface Specification 1.1. Its physical layer supports fly-by concatenation, arbitration acceleration, and multispeed reset - all verified for interoperability with FireWire™ and i.LINK™ implementations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCI Compliance | PCI Local Bus Spec Rev 2.3, supports burst transfers, posted writes, and 32-bit addressing for host-to-card throughput optimization |
| 1394 Data Rates | 100/200/400 Mbps - enables compatibility with legacy and high-speed FireWire peripherals without external rate negotiation logic |
| Power Domains | 1.5-V core logic with internal regulator + 3.3-V I/O - eliminates need for external core LDO in host designs |
| CardBus Support | Hot insertion/removal with internal signal buffering - removes requirement for discrete hot-swap controllers or level shifters |
| Interrupt Architecture | Serialized IRQ + multiple interrupt modes + register-access-fail interrupt - simplifies driver exception handling and improves system debug visibility |
| FIFO Depth | Deep FIFOs for both PCI and 1394 paths - tolerates >10 µs host latency while sustaining 132-MBPS burst transfers |
| PHY-Link Functions | Resynchronization of incoming 1394 data to local clock + encode/decode at bit level - ensures deterministic timing alignment across speed transitions |
Pinout & Package
PCI4515AZHK is housed in a 257-pin MicroStar BGA (ZHK package), 15 mm × 15 mm, 1.0 mm pitch, RoHS-compliant, MSL Level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | PCI Clock Input | Accepts 33 MHz PCI reference clock; internally distributed to both PCI and 1394 subsystems for synchronous operation |
| TPBIAS | Cable Port Bias | Provides dedicated bias voltage to 1394 differential pair - ensures proper common-mode voltage for cable detection and link training |
| SUSPEND# | PCI Power Management | Active-low signal indicating D3cold entry; triggers automatic power-down of inactive 1394 ports and CardBus interface |
| LED_A / LED_B | Activity Indicators | Open-drain outputs for CardBus and 1394 activity LEDs - directly drive standard 20-mA indicator LEDs without external drivers |
| PHY_SCLK | PHY Serial Clock | Internal clock for PHY register access; register access fail interrupt asserts when SCLK is inactive - aids firmware diagnostics |
| MF[7:0] | Multifunction Terminals | Programmable GPIOs supporting PCI LOCK, serial/parallel interrupts, VGA palette decode, or platform-specific signaling - reduces need for companion logic |
Key Features
| Feature | Design Value |
|---|---|
| IEEE 1394a-2000 Full PHY/Link Integration | Eliminates need for discrete PHY IC and separate OHCI controller - reduces BOM count and PCB area by ~35 mm² |
| ExCA Register Compatibility | Enables reuse of existing Intel 82365SL-DF driver stacks - cuts Windows/Linux driver development time by up to 60% |
| PCI Function Separation (F0/F2) | Allows independent reset, power gating, and enumeration of CardBus and 1394 subsystems - improves system-level fault isolation |
| Serial ROM Interface | Loads Subsystem ID/Vendor ID at boot - enables OEM branding and custom device enumeration without firmware modification |
| Connection Debounce & Arbitrated Short Reset | Prevents false link-up events during cable mating - increases 1394 link reliability in portable docking applications |
Applications
| Mobile Docking Station | Digital Video Capture Adapter |
|---|---|

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 |
|---|---|---|---|
| TIBB02314 | Single-function 1394a PHY only; no CardBus controller or PCI bridge logic | Requires external PCI-to-CardBus bridge (e.g., TI PCI4510) - increases component count and layout complexity | Select when only 1394 expansion is needed and CardBus functionality is handled elsewhere |
| PCI4510AGHK | CardBus-only controller (no 1394 PHY/Link); same BGA-257 package footprint but different pinout and function mapping | Cannot support FireWire peripherals - limits use to legacy PC Card expansion only | Select when system already includes discrete 1394 controller or FireWire is not required |
Compared with TIBB02314 and PCI4510AGHK, the PCI4515AZHK uniquely integrates both CardBus and 1394a functions in one die - reducing interconnect latency, eliminating board-level timing skew between interfaces, and enabling coordinated power state transitions across both domains.

FAQ
What is the primary function of the PCI4515AZHK?
The PCI4515AZHK is a dual-function integrated controller: Function 0 implements a PCI-to-CardBus bridge compliant with PC Card Standard 8.1 and ExCA registers, while Function 2 delivers full IEEE 1394a-2000 PHY and Link-layer capability. It enables simultaneous CardBus peripheral expansion and FireWire device connectivity from a single PCI slot - a capability confirmed in TI's SLLA241 datasheet and validated in production docking station designs.
Is the PCI4515AZHK pin-compatible with other TI PCI45xx devices?
No, the PCI4515AZHK is not pin-compatible with other members of the PCI45xx family such as PCI4510AGHK. Although both use 257-pin BGA packages, the ZHK and GHK variants have distinct pinouts, different multifunction terminal assignments, and non-overlapping power/ground ball placements - confirmed by TI's PACKAGE OPTION ADDENDUM dated 24-Feb-2009.
Does the PCI4515AZHK support isochronous data transfer for video applications?
Yes, the PCI4515AZHK supports isochronous receive dual-buffer mode and guarantees low-jitter cycle timer synchronization - features explicitly documented for DV and digital video capture applications in the SLLA241 datasheet. Its deep FIFOs and SBP-2–optimized physical data path ensure sustained 25-MB/s isochronous bandwidth required for SMPTE 259M-compliant video streams.
What power management features does the PCI4515AZHK provide?
The PCI4515AZHK implements PCI D0–D3 power states, ultralow-power sleep mode, automatic power-down of inactive 1394 ports, and PME signaling per 1394 OHCI specification. It also supports ACPI 2.0 and Intel Mobile Power Guideline 2000 - enabling battery-aware operation in portable docking systems without external power sequencers.
Can the PCI4515AZHK be used in new designs today?
The PCI4515AZHK is marked OBSOLETE by Texas Instruments and is not recommended for new designs. However, Aetrix Electronics maintains traceable inventory and supports legacy production programs, industrial retrofits, and repair-bill-of-materials continuity where functional equivalence and long-term supply assurance are critical - consistent with TI's stated lifetime-buy guidance for discontinued components.
