Product details
Overview
PCI7410ZHK from Texas Instruments is a four-function, 33-MHz PCI-to-CardBus bridge IC integrating PC Card socket control (Function 0), SD/MMC/Memory Stick interface (Function 1), IEEE 1394a-2000 OHCI PHY/Link-layer controller with two fully compliant cable ports (Function 2), and firmware loading interface (Function 3). It supports 100/200/400 Mbits/s data rates, 1.8-V core / 3.3-V I/O operation, and PCI power states D0–D3 for notebook and mobile docking applications.
For engineers reviewing the PCI7410ZHK datasheet, PCI7410ZHK pinout, PCI7410ZHK application, or PCI7410ZHK equivalent, key selection criteria include dual 1394a port compliance, ExCA register compatibility with Intel 82365SL–DF, integrated SD/MMC/Memory Stick socket support, and PCI 2.3/ACPI 2.0/PC2001 certification for legacy and low-power embedded PC Card designs.
Technical Context
The PCI7410ZHK implements a multi-function PCI device where Function 2 delivers full IEEE 1394a-2000 OHCI compliance-including arbitration acceleration, fly-by concatenation, port disable/suspend/resume, and physical write posting-while synchronizing inbound data to a local 49.152-MHz clock derived from an internal PLL locked to a 24.576-MHz crystal. Each 1394 port features independent TPBIAS biasing, line condition monitoring, and differential TPA/TPB transceivers.
Function 0 provides PC Card Standard 8.0-compliant socket control with hot insertion/removal support, subtractive decoding, and VGA/palette memory/I/O options; Function 1 offers dedicated SD/MMC or Memory Stick interface logic; Function 3 enables firmware loading into internal RAM via an I/O-mapped window. All functions share a unified 32-bit PCI interface with burst transfers, deep FIFOs, and serialized IRQ support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-CardBus + 1394 interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCI7421ZHK | Successor device with enhanced 1394b support (S800), improved thermal performance, and updated packaging (225-ball BGA); retains same pinout and register compatibility | Required for new designs needing S800 speed or longer lifecycle; not suitable for cost-sensitive legacy replacements where PCI7410ZHK remains in stock | Select PCI7421ZHK for future-proof 1394b deployments; PCI7410ZHK remains viable for maintenance of existing PC Card systems with S400-only requirements |
| TUSB2046B | USB 2.0 hub controller only; no 1394, SD/MMC, or CardBus functionality; 32-pin QFP package; operates at 3.3 V only | Applicable only where USB-not FireWire or flash card-connectivity is needed; cannot replace PCI7410ZHK's multi-interface role | Not a functional alternative; included only as a point of contrast for designers evaluating interface consolidation strategies |
Compared with PCI7421ZHK, the PCI7410ZHK offers identical register-level compatibility and S400 1394a support but lacks S800 capability and uses the older 209-pin GHK BGA; versus TUSB2046B, it delivers fundamentally different functionality-integrated 1394+CardBus+flash media-not USB expansion alone.

FAQ
What is the primary function of the PCI7410ZHK in a PC Card design?
The PCI7410ZHK serves as a four-function PCI-to-CardBus bridge IC. Its primary role is to integrate PC Card socket control, SD/MMC/Memory Stick interface, dual-port IEEE 1394a-2000 OHCI PHY/Link-layer controller, and firmware loader into one device. In a PC Card design, the PCI7410ZHK enables seamless communication between the host PCI bus and peripheral cards while providing native FireWire connectivity and flash media support - all without requiring external glue logic or multiple discrete controllers.
Does the PCI7410ZHK support both 3.3-V and 5-V PCI signaling environments?
Yes, the PCI7410ZHK supports universal PCI interfaces compatible with both 3.3-V and 5-V PCI signaling environments. Its I/O cells are designed for 3.3-V operation but tolerate 5-V signaling levels per PCI Local Bus Specification Revision 2.3. This dual-voltage compatibility allows the PCI7410ZHK to be used in mixed-voltage motherboard designs without level-shifting circuitry, simplifying integration into legacy and transitional PCI platforms.
How does the PCI7410ZHK handle power management for battery-powered applications?
The PCI7410ZHK implements comprehensive power management for battery-powered applications through PCI-defined D0–D3 power states, automatic device power-down during suspend, inactive port power gating, and an ultralow-power sleep mode drawing less than 100 µA. It complies with Intel Mobile Power Guideline 2000 and ACPI 2.0, enabling OS-directed power state transitions. The 1.8-V core voltage - generated internally from 3.3-V I/O - further reduces dynamic power consumption during active 1394 or CardBus operations.
Is the PCI7410ZHK pin-compatible with the Intel 82365SL–DF ExCA controller?
Yes, the PCI7410ZHK is register-compatible with the Intel 82365SL–DF ExCA controller, meaning its ExCA register map matches exactly - allowing existing PC Card socket service software to operate without modification. However, pin compatibility is not guaranteed: the PCI7410ZHK uses a 209-pin MICROSTAR BGA package, whereas the 82365SL–DF uses a 128-pin PQFP. Therefore, while software migration is seamless, hardware layout requires redesign to accommodate the BGA footprint and routing constraints.
What external components are required for basic PCI7410ZHK operation?
For basic PCI7410ZHK operation, you must provide a 24.576-MHz crystal (or external clock) for the 1394 PHY PLL, 3.3-V and 1.8-V power supplies (with appropriate decoupling capacitors), 33-MHz PCI clock input, and proper termination (110-Ω differential) on each 1394 TPA/TPB pair. Optional components include serial ROM for subsystem ID loading and discrete logic for SD/MMC vs. Memory Stick mode selection - though the latter can also be strapped via GPIO pins.
