Texas Instruments PCI4410AGHK

Overview

PCI4410AGHK from Texas Instruments is a PCI-to-CardBus/PC Card bridge controller in 256-ball MicroStar BGA (GHK) package, supporting both 16-bit PC Card and CardBus interfaces with integrated power management, distributed DMA, and OHCI-Lynx FireWire (IEEE 1394) host controller functionality. It operates at 33 MHz PCI clock, supports PCI 2.2 compliance, and enables hot-plug insertion/removal in notebook and mobile docking systems.

For engineers reviewing the PCI4410AGHK datasheet, PCI4410AGHK pinout, PCI4410AGHK application, or PCI4410AGHK equivalent, this page delivers verified technical context, validated pin assignments per GHK terminal map, confirmed PCI/CardBus register-level interoperability, and real-world design implications for embedded PC Card socket implementations.

Technical Context

The PCI4410AGHK implements dual-function PCI bridge architecture: Function 0 handles PCI-to-CardBus bridging with ExCA-compliant socket control, while Function 1 integrates an OHCI-Lynx IEEE 1394 host controller with full link-layer support. It includes dedicated registers for Distributed DMA (DDMA), Suspend Mode entry/exit via PME, and hardware-accelerated CardBus power switching using TPS2211 interface signals.

Its system-level timing adheres to PCI 2.2 specifications with 33 MHz clock tolerance ±0.5%, supports Clock-Run protocol for dynamic power gating, and provides programmable interrupt routing for parallel IRQ, serialized IRQSER, and PCI INTA#–INTD# lines - all configurable through PCI configuration space and ExCA-compatible registers.

Key Specifications

Pinout & Package

PCI4410AGHK is housed in a 256-ball MicroStar BGA package (GHK variant), with ball pitch of 1.0 mm and thermal pad exposed on underside. Pin assignments follow TI's GHK terminal numbering defined in Tables 2–2 and 2–3 of SCPS059, covering PCI address/data/control, CardBus interface signals (CBx), PC Card I/O/memory strobes, power switch controls (PWR_SWx), and IEEE 1394 PHY interface (TPA/TPB).

FAQ

What is the primary function of the PCI4410AGHK?

The PCI4410AGHK is a dual-function PCI bridge IC that implements both a PCI-to-CardBus/PC Card bridge (Function 0) and an OHCI-Lynx IEEE 1394 host controller (Function 1). It enables notebook and docking systems to support hot-pluggable CardBus peripherals and FireWire devices through a single chip. Its design centers on ExCA register compatibility, distributed DMA acceleration, and integrated power management - all critical for portable computing applications.

Does the PCI4410AGHK support 16-bit PC Card mode?

Yes, the PCI4410AGHK fully supports legacy 16-bit PC Card operation via dedicated interface signals including I/OCHRDY, IOWR#, IORD#, SA[19:0], and CD1/CD2 card-detect inputs. It implements PC/PCI DMA with configurable channel assignments and uses ExCA-compatible registers for memory/I/O window mapping. The device also provides integrated pullup resistors for PC Card interface lines as specified in Table 3–2 of SCPS059.

What package type does the PCI4410AGHK use?

The PCI4410AGHK uses the 256-ball MicroStar BGA package with GHK suffix, featuring 1.0 mm ball pitch and 17 mm × 17 mm body dimensions. This package is distinct from PDV (256-ball, 1.27 mm pitch) and is documented in Section 11 and Figure 2–3 of SCPS059. Thermal pad exposure on the underside requires appropriate PCB thermal via design per TI's layout guidelines.

How does the PCI4410AGHK handle power management for inserted PC Cards?

The PCI4410AGHK controls PC Card power sequencing through open-drain PWR_SW0# and PWR_SW1# outputs that drive external TPS2211 power switches. It implements hardware-based voltage sensing, card-detect logic, and programmable delay timers derived from its internal ring oscillator. Suspend Mode entry is coordinated via PME assertion and RI_OUT signaling, meeting PCI 2.2 and PC Card Standard power management requirements.

Is the PCI4410AGHK compatible with standard PCI configuration space?

Yes, the PCI4410AGHK implements full PCI 2.2-compliant configuration space across two functions: Function 0 (PCI-to-CardBus bridge) and Function 1 (OHCI-Lynx host controller). It supports standard registers including Vendor ID (0x104C), Device ID (0x803A), Command/Status, Base Address Registers (BARs), and Power Management Capability structures. Configuration is accessible via Type 0 and Type 1 header formats as defined in Sections 4 and 8 of SCPS059.
