Product details
Overview
PCI4515ZHK from Texas Instruments is a dual-function PCI-to-CardBus and OHCI 1394 (FireWire) host controller IC, integrating Function 0 (CardBus bridge) and Function 2 (IEEE 1394 OHCI link layer) on a single die. It supports 32-bit/33 MHz PCI bus interface, CardBus 5V/3.3V socket control, IEEE 1394a-2000 PHY interface, integrated LDO voltage regulator, and full ACPI/PCI power management. It is used in legacy PC Card expansion slots for FireWire-equipped laptops and docking stations.
For engineers reviewing the PCI4515ZHK datasheet, PCI4515ZHK pinout, PCI4515ZHK application, or PCI4515ZHK equivalent, key selection considerations include dual-function integration, ExCA register compatibility, OHCI 1394 timing compliance, CardBus power sequencing support, and TI's discontinued lifecycle status requiring obsolescence-aware sourcing.
Technical Context
The PCI4515ZHK implements two independent PCI functions: Function 0 acts as a CardBus bridge with ExCA-compliant socket registers, supporting 16-bit PC Card and CardBus (32-bit, 33 MHz) modes; Function 2 implements the OHCI 1394 link-layer controller with IEEE 1394a-2000 compliance, including isochronous transmit/receive context DMA, self-ID processing, and CSR register access. Both functions share the same PCI configuration space but operate via separate base address mappings.
It integrates a 3.3-V low-dropout voltage regulator for CardBus I/O, internal ring oscillator for reset timing, programmable interrupt subsystem (IRQSER/parallel IRQ), and serial EEPROM (I²C) interface for configuration storage. Power management includes PCI D0–D3hot states, CardBus Clock Run mode, suspend/resume signaling, and PME event generation for both functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCI Interface | 32-bit, 33 MHz compliant; enables connection to host CPU via standard PCI slot without glue logic. |
| CardBus Support | Full ExCA register set (Function 0); supports hot-plug detection, power switching, and 5V/3.3V card auto-sensing. |
| IEEE 1394 Interface | OHCI 1394a-2000 link-layer controller (Function 2); handles packet assembly, isochronous DMA, and bus management. |
| Integrated LDO | On-chip 3.3-V regulator with 500-mA output; powers CardBus socket logic and reduces external component count. |
| Power Management | ACPI-compliant; supports PCI D0–D3hot, CardBus Clock Run, suspend/resume, and PME assertion for both functions. |
| Serial EEPROM Interface | I²C-compatible serial bus (up to 400 kHz); stores vendor/device IDs, subsystem IDs, and configuration data. |
| Package | 208-pin PQFP (ZHK suffix); 28 × 28 mm body, 0.65 mm pitch; RoHS-compliant lead-free finish. |
Pinout & Package
PCI4515ZHK is housed in a 208-pin Plastic Quad Flat Package (PQFP), designated ZHK per TI's ordering nomenclature. The package features 28 mm × 28 mm body size, 0.65 mm lead pitch, and gull-wing leads compatible with standard surface-mount reflow processes.

| CB_VCC | CardBus I/O Supply Input | Input for 3.3 V or 5 V; selected automatically based on card presence; powers CardBus socket interface circuitry. |
| PHY_CLK | 1394 PHY Clock Output | Drives external IEEE 1394 PHY device (e.g., TSB41AB2); provides 49.152 MHz clock synchronized to isochronous cycle timer. |
| IRQ# | PCI Interrupt Request Output | Open-drain active-low signal shared by both functions; asserts on CardBus events or OHCI interrupts per mask settings. |
| SCL / SDA | I²C Serial Bus Interface | Connects to external serial EEPROM (e.g., 24LC02B); stores persistent configuration and subsystem identifiers. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PCI Function Integration | Single-die implementation of CardBus bridge (Function 0) and OHCI 1394 controller (Function 2); eliminates inter-chip timing constraints and reduces PCB area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-CardBus and IEEE 1394 controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCI4510ZHK | Single-function variant: CardBus bridge only (no OHCI 1394); lacks Function 2, PHY interface pins, and isochronous DMA engine. | Applicable only where FireWire functionality is not required; lower gate count and power consumption. | Select PCI4510ZHK when designing non-FireWire CardBus expansion solutions and cost/power optimization is critical. |
| TUSB2046B | USB 2.0 hub controller (not PCI/CardBus); no PCI interface, no OHCI, no ExCA registers; requires separate USB host controller. | Targets USB peripheral expansion-not direct replacement; incompatible with PC Card mechanical or electrical interface. | Consider only for greenfield USB-based expansion designs; not a functional or pin-compatible alternative to PCI4515ZHK. |
Compared with PCI4515ZHK, PCI4510ZHK removes FireWire capability but retains full CardBus bridge functionality and ExCA compliance, whereas TUSB2046B belongs to a different interface domain entirely and cannot satisfy the dual-role PCI/CardBus/1394 integration requirement.

FAQ
What is the primary function of the PCI4515ZHK?
The PCI4515ZHK is a dual-function PCI host controller integrating a CardBus bridge (Function 0) and an OHCI-compliant IEEE 1394 link-layer controller (Function 2). It enables PC Card sockets to support both legacy 16-bit cards and high-speed CardBus peripherals while providing native FireWire connectivity through hardware-accelerated isochronous DMA and CSR management - all within a single PCI device.
Does the PCI4515ZHK support both 3.3-V and 5-V CardBus operation?
Yes, the PCI4515ZHK supports automatic voltage detection and switching for 3.3-V and 5-V CardBus operation. Its CB_VCC pin senses card voltage class, and internal logic configures I/O buffers accordingly. The device also includes integrated level-shifting circuitry and clamping diodes to ensure safe interoperability across voltage domains without external components.
Is the PCI4515ZHK pin-compatible with other members of the PCI45xx family?
The PCI4515ZHK shares the same 208-pin PQFP (ZHK) package and core pinout with PCI4510ZHK and PCI4511ZHK, but differs in function-specific pins (e.g., PHY_CLK, PHY_DATA, and OHCI DMA request lines). While mechanical and basic PCI interface pins align, full pin compatibility requires matching the exact function set - PCI4515ZHK is not a drop-in replacement for single-function variants without firmware and layout review.
What power management features does the PCI4515ZHK implement?
The PCI4515ZHK implements comprehensive power management including PCI D0–D3hot states, CardBus Clock Run mode, suspend/resume signaling, and PME assertion for both Function 0 and Function 2. It supports ACPI-compliant system-level control and includes dedicated registers (e.g., Power Management Capabilities, Control/Status) to manage wake events, clock gating, and voltage scaling per function.
Where can I find the official datasheet and reference design files for the PCI4515ZHK?
The official PCI4515ZHK datasheet (SCPS086, July 2004) and related documentation are archived on Texas Instruments' website under legacy connectivity products. Reference schematics, layout guidelines, and ExCA register mapping tables are included in the data manual. Aetrix Electronics provides direct access to verified PDF copies and TI-authorized design files upon request for qualified engineering engagements.
