Product details
Overview
PCI1515ZHK 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 an LDO voltage regulator, provides ExCA register compatibility with Intel 82365SL-DF, and enables hot insertion/removal via internal buffering - deployed in legacy laptop docking stations and industrial PC Card expansion systems.
For engineers reviewing the PCI1515ZHK datasheet, PCI1515ZHK pinout, PCI1515ZHK application, or PCI1515ZHK equivalent, key selection criteria include ExCA register compatibility, dual-voltage (3.3 V/5 V) card support, integrated power management for Suspend Mode, PCI Command Register programmability for posted writes, and multifunction terminal configurability for LED indicators and ACPI-compliant GPIO.
Technical Context
The PCI1515ZHK implements a full 32-bit PCI interface with pipelined data path logic supporting 8-, 16-, and 32-bit PC Card access using native 32-bit PCI cycles. Its internal buffering eliminates need for external bus transceivers during hot-swap operations.
It features two functional domains: Function 0 (CardBus socket controller) with ExCA-compatible registers and PCI Configuration Space, plus integrated subsystems including Serial EEPROM (I²C) interface, programmable interrupt subsystem (parallel IRQ, serialized IRQSER, SMI), and Power Management Control/Status registers aligned with PCI PM 1.1 and ACPI 1.0b.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCI Compliance | PCI Local Bus Specification Revision 2.3 - ensures interoperability with standard PCI host bridges and system BIOS enumeration. |
| PC Card Support | 16-bit, CardBus, and USB-custom PC Cards - enables backward compatibility with legacy 16-bit cards and high-speed CardBus peripherals. |
| Operating Voltage | 3.3 V or 5 V card power - selectable per slot via software-controlled power switch interface, supporting mixed-voltage card environments. |
| LDO Regulator | Integrated low-dropout voltage regulator - supplies stable 3.3 V core power without external LDO, reducing BOM count and layout complexity. |
| ExCA Compatibility | Register-level compatible with Intel 82365SL-DF - allows reuse of existing ExCA driver stacks and simplifies migration from legacy controllers. |
| Hot-Swap Support | Internally buffered card signals - eliminates need for external hot-swap protection circuitry and enables safe insertion/removal under OS control. |
| Suspend Mode | PCI Power Management (PME) and ACPI-compliant suspend/resume - reduces system power consumption during idle states while preserving socket state. |
Pinout & Package
PCI1515ZHK is housed in a 208-pin TQFP package (GHK/ZHK suffix per TI documentation), with pin assignments defined in Figure 2−1 ("PCI1515 GHK/ZHK-Package Terminal Diagram") and Tables 2−1 through 2−14 of the SCPS099 data manual.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | PCI Clock Input | Accepts 33 MHz PCI clock signal; drives internal timing for PCI transaction synchronization and configuration space access. |
| RST# | PCI Reset Input | Active-low asynchronous reset that initializes PCI configuration registers and clears pending interrupts and socket state. |
| AD[31:0] | PCI Address/Data Multiplexed Bus | 32-bit multiplexed address/data lines - used for PCI configuration reads/writes and memory-mapped socket register access. |
| C/BE#[3:0] | PCI Command/Byte Enable | Defines transaction type (I/O, memory, config) and active byte lanes during data phase - critical for proper ExCA register mapping. |
| FRAME#, IRDY#, TRDY# | PCI Transaction Control | Coordinate initiation, readiness, and completion of PCI cycles - required for reliable bridging of burst transfers to PC Card interface. |
| CD1#, CD2# | Card Detect Inputs | Dual card-detect signals - enable independent detection of two physical card positions in multi-socket implementations. |
| VCC_3V3, VCC_5V | Power Supply Inputs | Separate 3.3 V and 5 V supply pins - feed internal LDO and power-switch circuitry to deliver appropriate voltage to inserted cards. |
Key Features
| Feature | Design Value |
|---|---|
| ExCA Register Compatibility | Full register mapping alignment with Intel 82365SL-DF - enables drop-in driver reuse and avoids firmware requalification effort. |
| Programmable Posted Writes | Configurable via PCI Command Register - improves PCI bus utilization by allowing host to issue non-blocking writes to socket registers. |
| ACPI-Compliant GPIO | Eight multifunction terminals support ACPI _GPX methods - permits OS-level control of LEDs, card activity indicators, and platform-specific events. |
| Integrated Serial EEPROM Interface | I²C-compatible serial-bus interface - stores socket configuration, vendor ID, and subsystem ID in external EEPROM without requiring host CPU intervention. |
| CardBus Clock Run Protocol | Supports dynamic clock gating during idle - reduces power consumption in CardBus mode without disrupting link integrity or requiring resynchronization. |
Applications
| Industrial Docking Stations | Laptop Expansion Cradles |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PC Card bridge controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Intel 82365SL-DF | Original ExCA controller; no integrated LDO; requires external 3.3 V regulator and discrete hot-swap buffers. | Same ExCA register map but higher BOM cost and larger footprint due to external components. | Select when legacy driver validation is complete and board layout cannot accommodate ZHK's integrated LDO. |
| Texas Instruments PCI1520 | Two-socket variant with identical register set, enhanced thermal performance, and extended temperature range (–40°C to 85°C). | Supports dual-slot configurations and industrial ambient conditions; not pin-compatible with PCI1515ZHK. | Select for new dual-socket designs requiring wider operating temperature or higher reliability margins. |
Compared with Intel 82365SL-DF, PCI1515ZHK reduces component count via integrated LDO and buffering; compared with PCI1520, it offers lower cost and smaller footprint for single-socket applications but lacks extended temperature support and dual-socket capability.

FAQ
What is the primary function of the PCI1515ZHK?
The PCI1515ZHK is a single-function PCI-to-PC Card bridge controller that enables communication between a PCI host bus and 16-bit, CardBus, or USB-custom PC Cards. It handles enumeration, power management, hot-swap signaling, and register-level ExCA compatibility - all within a single 208-pin TQFP package. The PCI1515ZHK integrates key functions such as an LDO regulator and internal signal buffering to reduce external component count.
Is the PCI1515ZHK pin-compatible with the Intel 82365SL-DF?
No, the PCI1515ZHK is not pin-compatible with the Intel 82365SL-DF, though it is register-compatible at the ExCA level. The PCI1515ZHK uses a 208-pin TQFP (ZHK) package, whereas the 82365SL-DF uses a 208-pin PQFP with different pin assignments for power, ground, and multifunction signals. Board redesign is required for replacement, but driver software remains reusable due to ExCA register alignment.
Does the PCI1515ZHK support both 3.3 V and 5 V PC Cards?
Yes, the PCI1515ZHK supports both 3.3 V and 5 V PC Cards through dedicated VCC_3V3 and VCC_5V supply inputs and software-controllable power switches. Its internal logic detects card voltage requirements via CD1#/CD2# and VPP/VCC sense lines, then activates the appropriate power rail - enabling mixed-voltage operation in single-socket systems without manual configuration.
What power management features does the PCI1515ZHK provide?
The PCI1515ZHK supports PCI Power Management (PME) and ACPI-compliant Suspend Mode, including wake-on-card-insertion and runtime clock gating via CardBus Clock Run Protocol. Its Power Management Control/Status Register (offset 0x44) and Power Management Capabilities Register (offset 0x40) implement PCI PM 1.1 functionality, allowing the host to place the device in D0–D3 states while preserving socket context across resume transitions.
Can the PCI1515ZHK be used in new designs today?
Yes, the PCI1515ZHK remains viable for new designs targeting legacy PC Card infrastructure, especially where long-term availability, driver reuse, and simplified power architecture are priorities. While PC Card is deprecated in consumer laptops, it persists in industrial, military, and test equipment markets - and Aetrix Electronics maintains active inventory and lifecycle coordination for PCI1515ZHK to support ongoing production.
