Texas Instruments PCI7410PDV

Overview

PCI7410PDV 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 FireWire data rates, 1.8-V core / 3.3-V I/O operation, and PCI power states D0–D3 for mobile computing systems.

For engineers reviewing the PCI7410PDV datasheet, PCI7410PDV pinout, PCI7410PDV application, or PCI7410PDV equivalent, key selection considerations include its dual-role 1394 PHY/LLC integration, ExCA-compatible register mapping, support for hot insertion/removal of PC Cards, and compliance with PC 2001, ACPI 2.0, and PCI 2.3 standards in battery-constrained notebook platforms.

Technical Context

The PCI7410PDV implements a tightly coupled PHY-Link architecture where the integrated LLC handles OHCI-compliant isochronous/asynchronous packet processing while the PHY layer performs data-strobe encoding, line condition monitoring, and differential transmit/receive on two independent twisted-pair A/B ports. Its internal PLL derives 393.216 MHz from a 24.576 MHz crystal to generate S100/S200/S400 signaling clocks.

Function-level segmentation isolates responsibilities: Function 0 manages 16-bit/CardBus socket timing and voltage switching; Function 1 provides dedicated SD/MMC or Memory Stick protocol signaling; Function 2 integrates full 1394a arbitration, fly-by concatenation, port suspend/resume, and cable power presence detection; Function 3 enables firmware load via I/O-mapped RAM access.

Key Specifications

Pinout & Package

PCI7410PDV is packaged in a 209-pin MICROSTAR BGA (GHK package drawing) with 0.8-mm ball pitch and RoHS-compliant lead finish. The device uses area-array ball layout optimized for high-speed PCI and 1394 signal integrity, requiring controlled-impedance PCB routing and thermal via placement under the die pad.

FAQ

What is the primary function of the PCI7410PDV in a notebook PC design?

The PCI7410PDV serves as a four-function PCI-to-CardBus bridge IC that integrates PC Card socket control, SD/MMC/Memory Stick interface, dual-port IEEE 1394a-2000 PHY/Link-layer controller, and firmware loader. In notebook designs, PCI7410PDV enables compact, low-power expansion cards supporting FireWire video capture and flash memory access through a single Type II PC Card slot without requiring external controllers or level shifters.

Does the PCI7410PDV support both 3.3-V and 5-V PCI signaling environments?

Yes, the PCI7410PDV features universal PCI interfaces compatible with both 3.3-V and 5-V PCI signaling environments. Its I/O cells operate at 3.3 V and include internal voltage regulation for 1.8-V core logic, allowing seamless integration into mixed-voltage motherboard designs while maintaining full PCI Local Bus Specification Revision 2.3 compliance.

How does the PCI7410PDV handle power management for battery-powered applications?

The PCI7410PDV implements comprehensive power management including PCI D0–D3 states, automatic device power-down during suspend, inactive port power-down, and ultralow-power sleep mode. It complies with Intel Mobile Power Guideline and ACPI 2.0, enabling OS-directed power state transitions and reducing system-level power consumption in notebook PCs without sacrificing 1394 or SD performance.

What external components are required for the PCI7410PDV's 1394 interface to operate?

The PCI7410PDV requires only a 24.576-MHz fundamental-mode crystal (or optional external clock) to generate all necessary 1394 timing signals. Each 1394 port needs discrete 1.8-kΩ pull-up resistors on TPBIAS lines and standard 110-Ω differential termination on TPB/TPA pairs. No external transceivers, level shifters, or PLLs are needed-the PHY layer is fully integrated within the PCI7410PDV.

Is the PCI7410PDV pin-compatible with the Intel 82365SL-DF ExCA controller?

Yes, the PCI7410PDV implements ExCA-compatible registers mapped in memory or I/O space and is register-compatible with the Intel 82365SL-DF controller. This allows existing PCMCIA socket service software to operate without modification when migrating to PCI7410PDV-based designs, preserving investment in driver development and validation effort.
