Product details
Overview
PCI7515GHK from Texas Instruments is a multifunction PCI-to-CardBus/IEEE 1394/Smart Card controller IC implementing three PCI functions (Function 0: CardBus bridge, Function 2: OHCI 1394 host controller, Function 5: Smart Card interface) in a single 256-pin PBGA package. It supports 33-MHz PCI bus operation, 48-MHz CardBus clock, and IEEE 1394a-2000 PHY interface for high-speed serial I/O in portable computing systems.
For engineers reviewing the PCI7515GHK datasheet, PCI7515GHK pinout, PCI7515GHK application, or PCI7515GHK equivalent, key selection considerations include its triple-function integration, PCI power management compliance (D0–D3hot/D3cold), integrated LDO voltage regulator, ExCA register compatibility, and support for legacy PC Card 16-bit and CardBus 32-bit interfaces.
Technical Context
The PCI7515GHK implements a PCI-to-CardBus bridge with full ExCA register mapping (Function 0), an OHCI-compliant IEEE 1394a-2000 host controller (Function 2) supporting isochronous transmit/receive contexts and cycle timer synchronization, and a Smart Card interface (Function 5) compliant with ISO/IEC 7816-3 electrical signaling and protocol timing. All three functions share a common 33-MHz PCI bus interface and independent power domains.
It integrates a 48-MHz internal ring oscillator for CardBus timing, programmable interrupt routing (IRQSER, parallel IRQ, SMI), and a 3.3-V LDO voltage regulator for CardBus socket power. Power management follows PCI 2.2 and ACPI 1.0 specifications, with per-function PME capability and suspend/resume state retention across all three PCI functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multifunction PCI interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB6010 | USB 2.0 OTG transceiver with integrated PHY; no CardBus or Smart Card support; single-function USB-only device. | Targets USB peripheral connectivity only; cannot replace PCI7515GHK's triple-interface capability or PC Card legacy support. | Select only if application requires USB 2.0 host/peripheral functionality without need for CardBus, 1394, or smart card interfaces. |
| PCI9054-AC | Dedicated PCI-to-Local Bus bridge (no native CardBus/1394/Smart Card logic); requires external ASIC or FPGA for those functions. | Suitable for custom local bus peripherals but lacks integrated standards compliance-adds design complexity and validation burden for PC Card/1394/EMV use cases. | Choose only for proprietary bus expansion where full standards compliance is not required and external logic can be justified. |

FAQ
What is the primary function of the PCI7515GHK?
The PCI7515GHK is a multifunction PCI controller IC integrating three distinct PCI functions: a CardBus bridge (Function 0), an OHCI-compliant IEEE 1394a-2000 host controller (Function 2), and a Smart Card interface (Function 5). It enables a single PCI slot to support legacy PC Cards, high-speed 1394 peripherals, and secure smart card transactions-all within one 256-pin PBGA package. This integration reduces system complexity and board space in portable and embedded platforms.
Does the PCI7515GHK support both 16-bit PC Cards and CardBus cards?
Yes, the PCI7515GHK fully supports both 16-bit PC Cards and 32-bit CardBus cards through its Function 0 implementation. It complies with PC Card Standard Release 7.0 and provides ExCA register compatibility, card detect (CD1#/CD2#), power switch control, and 48-MHz CardBus clock generation. The device automatically detects card type and configures appropriate timing and signaling per the PC Card specification.
What IEEE 1394 standards does the PCI7515GHK implement?
The PCI7515GHK implements IEEE 1394a-2000 via its OHCI 1.1-compliant Function 2, supporting data rates up to 400 Mbps, isochronous transmit/receive context management, self-ID completion, and full CSR architecture. It does not support IEEE 1394b (800/1600 Mbps) or FireWire S800TP. The PHY layer is implemented externally; PCI7515GHK provides the link-layer controller and DMA engine only.
How does the PCI7515GHK handle power management across its three functions?
The PCI7515GHK implements independent PCI 2.2-compliant power management for each function: Function 0 (CardBus), Function 2 (1394), and Function 5 (Smart Card) each support D0–D3hot/D3cold states with individual PME# assertion capability. The device also includes an integrated 3.3-V LDO regulator for CardBus socket power and supports ACPI 1.0 system-level suspend/resume coordination across all functions without requiring external power sequencers.
Is an external crystal required for the PCI7515GHK to operate?
No external crystal is required for basic operation: the PCI7515GHK includes an internal 48-MHz ring oscillator for CardBus clock generation and accepts a 33-MHz PCI system clock on CLKIN. However, for IEEE 1394 applications requiring precise cycle timer accuracy (±100 ppm), TI recommends using an external 24.576-MHz crystal with the integrated PLL to meet IEEE 1394a timing specifications. The crystal connects to X1/X2 pins and is optional for non-1394 use cases.
