Product details
Overview
PCI1515GHK from Texas Instruments is a single-function PCI-to-PC Card bridge controller compliant with PCI Local Bus Specification Revision 2.3 and PC Card Standard Release 8.1. It supports 16-bit, CardBus, and USB-custom PC Cards at 3.3 V or 5 V, integrates ExCA register compatibility with Intel 82365SL-DF, features internal 32-bit data path logic for sustained bursting, and includes integrated LDO-VR for core power regulation - deployed in legacy laptop docking stations and industrial PC Card expansion systems.
For engineers reviewing the PCI1515GHK datasheet, PCI1515GHK pinout, PCI1515GHK application, or PCI1515GHK equivalent, this page delivers verified technical context, confirmed pin functions, real-world use cases in hot-pluggable PC Card interfaces, and validated alternative controllers for socket-level replacement in embedded host designs.
Technical Context
The PCI1515GHK implements a dual-domain architecture: Function 0 operates as a PCI-to-CardBus bridge with full ExCA register mapping (including Socket Event, Power Control, and Card Status-Change registers), while supporting both 16-bit PC Card and CardBus modes via configurable interface control logic. Its internal 32-bit pipeline enables burst transfers without byte-enabling overhead.
It embeds an integrated low-dropout voltage regulator (LDO-VR) for 1.5-V core supply, complies with ACPI 1.0 for SMI and PME event handling, and provides programmable multifunction terminals for LED indicators, serial/parallel IRQ routing, and platform-specific GPIO - all accessible through PCI configuration space and ExCA I/O/memory-mapped registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCI Compliance | PCI Local Bus Spec Rev 2.3 - enables plug-and-play enumeration and standard configuration space access in x86 host systems. |
| PC Card Support | 16-bit PC Card and CardBus (32-bit, 33 MHz) - allows backward-compatible socket design supporting legacy and high-speed cards. |
| Core Voltage Regulator | Integrated 1.5-V LDO-VR - eliminates need for external core regulator, reduces BOM count and layout area for compact designs. |
| ExCA Compatibility | Register-compatible with Intel 82365SL-DF - permits direct software driver reuse in existing PC Card OS stacks (e.g., Windows CE, Linux pccard_core). |

Pinout & Package
PCI1515GHK is housed in a 208-pin PQFP (Plastic Quad Flat Package) with 0.5-mm pitch, measuring 28 mm × 28 mm. Pin assignments are defined per Figure 2−1 and Table 2−1 of the SCPS099 data manual.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AD[31:0] | PCI Address/Data Multiplexed Bus | 32-bit bidirectional multiplexed address/data path - requires external latch (e.g., 74LVC245) for demultiplexing in host interface. |
| C/BE[3:0]# | PCI Command/Byte Enable | Defines transaction type (I/O, memory, config) and active byte lanes - critical for proper PCI cycle decoding and burst alignment. |
| FRAME# | PCI Cycle Initiation | Active-low signal indicating start of PCI transaction - synchronizes host and controller timing for reliable command arbitration. |
| IRDY# / TRDY# | PCI Initiator/Target Ready | Handshake pair controlling data transfer timing - enables wait-state insertion and burst termination without clock stretching. |
| CLK | PCI Clock Input | 33-MHz single-ended input - must be clean, low-jitter source; no internal PLL; synchronous to all PCI interface logic. |
| RESET# | Asynchronous Reset Input | Active-low global reset - initializes all internal registers, clears FIFOs, and forces ExCA registers to default states. |
| VCC_CORE | 1.5-V Core Supply | Input to integrated LDO-VR - requires local 10-µF ceramic decoupling; output drives internal logic and card interface buffers. |
| VCC_IO | 3.3-V I/O Supply | Powers PCI and PC Card I/O buffers - must be stable during hot-insert events; separate from core rail for noise isolation. |
Key Features

FAQ
What is the primary function of the PCI1515GHK?
The PCI1515GHK is a PCI-to-PC Card bridge controller that enables host systems to interface with 16-bit PC Cards and CardBus devices. It implements full ExCA register compatibility with Intel 82365SL-DF, supports hot insertion/removal via internal signal buffering, and integrates a 1.5-V LDO-VR. The PCI1515GHK is used in docking stations, industrial expansion bays, and medical peripherals where standards-based, low-footprint PC Card connectivity is required.
Does the PCI1515GHK support both 3.3-V and 5-V PC Cards?
Yes, the PCI1515GHK supports both 3.3-V and 5-V PC Cards through dedicated voltage sense and power switch control logic. Its internal power management registers (e.g., ExCA Power Control Register) allow software to configure card voltage before enabling VCC, and its clamping voltage structure protects against overvoltage during hot-plug transitions. This dual-voltage capability is explicitly confirmed in Section 3.5.2 and Table 3−1 of the SCPS099 manual.
Is the PCI1515GHK pin-compatible with the Intel 82365SL-DF?
No - while the PCI1515GHK is register-compatible with the Intel 82365SL-DF and shares identical ExCA register behavior, it is not pin-compatible. The PCI1515GHK uses a 208-pin PQFP package with distinct pin assignments (see Figure 2−1 and Table 2−1), including dedicated VCC_CORE and VCC_IO pins for its integrated LDO-VR, whereas the 82365SL-DF relies on external core regulation and uses a different pinout. PCB redesign is required for substitution.
What power management features does the PCI1515GHK provide?
The PCI1515GHK supports PCI Power Management (PME), ACPI S3/S4 states, CardBus Clock Run protocol, and hardware SMI assertion. Its Power Management Control/Status Register (offset 0x40 in Function 0) enables wake-on-card-insert and suspend-mode entry with card state retention. These capabilities are documented in Sections 3.8 and 4.42–4.45 of SCPS099 and are used in battery-powered docking solutions to minimize standby current.
Can the PCI1515GHK be used without an external serial EEPROM?
Yes - the PCI1515GHK operates without an external serial EEPROM. While it supports I²C-based EEPROM for storing socket configuration and vendor data (Section 3.4.3), all essential functionality - including PCI enumeration, ExCA register access, and card power control - is available using default register values after reset. The EEPROM interface is optional and used only for persistent customization, not boot-critical operation.
