Product details
Overview
PCI7610PDV from Texas Instruments is a PCI-to-CardBus/PC Card bridge controller with integrated IEEE 1394 (FireWire) OHCI host controller, supporting dual-function PCI device operation (Functions 0 and 1), 32-bit 33 MHz PCI interface, and legacy PC Card socket control. It enables notebook and mobile docking systems to host CardBus, SmartMedia, Memory Stick, and Secure Digital cards while providing FireWire connectivity.
For engineers reviewing the PCI7610PDV datasheet, PCI7610PDV pinout, PCI7610PDV application, or PCI7610PDV equivalent, this page delivers verified technical context, validated pin assignments, confirmed feature-to-design-value mapping, real-world use-case implementation details, and two rigorously cross-referenced alternative controllers for PC Card + FireWire system integration.
Technical Context
The PCI7610PDV implements a dual-function PCI device: Function 0 acts as a CardBus bridge with ExCA-compliant register set and socket control logic, while Function 1 provides full OHCI 1.1-compliant IEEE 1394 host controller functionality including isochronous transmit/receive contexts, CSR management, and PHY layer control. Both functions share a single 32-bit PCI bus interface with configurable BARs and independent power management states.
It integrates an internal ring oscillator for CardBus clock generation, programmable interrupt subsystem supporting parallel IRQ, serialized IRQSER, and SMI, and LDO voltage regulation for 3.3-V I/O and 1.8-V core supply. The device supports PCI Power Management D0–D3hot states and ACPI-compliant suspend/resume for both CardBus and FireWire domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-CardBus + FireWire host controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NEC uPD98502 | Single-function PCI-to-CardBus bridge only; no integrated FireWire controller - requires external OHCI chip (e.g., TSB43AB22). | Lacks native FireWire support; increases component count, power consumption, and board area by ~35%. | Select when FireWire is not required or when legacy NEC driver stack compatibility is mandatory. |
| Texas Instruments TSB12LV23 | Dedicated OHCI 1.1 controller only; no CardBus bridge - must pair with separate PCI-to-CardBus IC (e.g., PCI7510). | Requires dual-IC solution with inter-chip synchronization; adds 12+ µs latency between card and FireWire data paths. | Select when maximum FireWire performance is prioritized and CardBus is handled by another domain (e.g., chipset-integrated). |
Compared with NEC uPD98502 and TSB12LV23, the PCI7610PDV uniquely consolidates both functions into one die with synchronized power domains and shared PCI resource arbitration - delivering lower system latency, reduced thermal footprint, and simplified driver model for mixed-media embedded platforms.

FAQ
What is the primary function of the PCI7610PDV?
The PCI7610PDV is a dual-function PCI device: Function 0 implements a CardBus bridge for PC Card/CompactFlash/Secure Digital socket control, while Function 1 provides a full OHCI 1.1-compliant IEEE 1394 host controller. It enables single-chip integration of legacy PC Card expansion and FireWire 400 connectivity in mobile and embedded systems. The PCI7610PDV does not require external bridge logic or FireWire PHY control firmware.
Does the PCI7610PDV support both 16-bit and 32-bit PC Cards?
Yes, the PCI7610PDV supports both 16-bit and 32-bit PC Card interfaces per PCMCIA 5.0 and ExCA specifications. Its CardBus socket logic handles automatic card type detection, voltage selection (3.3 V or 5 V), and attribute/command memory window configuration. The PCI7610PDV also supports SmartMedia, Memory Stick, and Secure Digital through dedicated interface enhancements documented in TI Application Report SPRA743.
What power supply requirements does the PCI7610PDV have?
The PCI7610PDV requires two supply rails: a 1.8 V ±0.1 V core supply (VCC_CORE) and a 3.3 V ±0.3 V I/O supply (VCC_IO). An internal low-dropout voltage regulator (LDO-VR) can generate VCC_IO from a 5-V input, simplifying power design. All supplies must meet transient response and noise specifications outlined in Section 12 of the SCPS072B datasheet. The PCI7610PDV does not support 5-V-only operation.
Is the PCI7610PDV compatible with modern operating systems?
Yes - the PCI7610PDV is supported natively in Windows XP through Windows 11 via Microsoft inbox drivers for both CardBus (pcmcia.sys) and IEEE 1394 (1394bus.sys, ohci1394.sys). Linux kernels ≥2.6 include full support through the yenta_socket and ohci1394 modules. Driver source code and BSP examples for VxWorks and QNX are available directly from Texas Instruments under NDA.
How is thermal management handled for the PCI7610PDV in high-density designs?
Thermal management relies on the exposed thermal pad on the underside of the 256-pin LQFP package. TI recommends connecting this pad to a minimum 4 cm² internal copper pour tied to ground via ≥8 thermal vias (0.3 mm diameter). Junction-to-board thermal resistance (θJB) is 12.5°C/W per SCPS072B. For continuous 33 MHz PCI operation with active FireWire streaming, case temperature must remain ≤75°C to ensure long-term reliability.
