Product details
Overview
The PCI1520ZHK from Texas Instruments is a dual-slot CardBus-to-PCI bridge controller in a 209-ball MicroStar BGA (ZHK) package, implementing full 32-bit PCI-to-CardBus bridging at 33 MHz with pipelined architecture, integrated LDO-VR for 2.5-V core supply, and hot-swap support for mixed 5-V/3.3-V 16-bit PC Cards and 3.3-V CardBus cards - deployed in notebook docking stations and industrial PC Card expansion systems.
For engineers reviewing the PCI1520ZHK datasheet, PCI1520ZHK pinout, PCI1520ZHK application, or PCI1520ZHK equivalent, this page delivers verified technical context on ExCA register compatibility, PCI/ISA interrupt routing options, CardBus socket power management, serial EEPROM subsystem ID loading, and ZV (Zoomed Video) signal support per PC Card Standard Rev. 7.1.
Technical Context
The PCI1520ZHK implements a dual-function PCI device (Function 0 and Function 1), each with independent ExCA-compliant configuration space and dedicated memory/I/O windows: five PCI memory windows and two I/O windows per 16-bit interface, plus two memory and two I/O windows per CardBus socket. Its internal buffering enables hot insertion/removal without external logic.
It supports multiple interrupt delivery modes - parallel PCI, serialized PCI (IRQSER), parallel ISA, and serialized ISA - and integrates a ring oscillator for clock generation when external clocks are unavailable. Power management includes Suspend Mode, CLKRUN protocol, and PME-capable registers compliant with PCI Bus Power Management Interface Spec Rev. 1.1.

Use Value: Enables concurrent high-bandwidth CardBus operation (e.g., 130+ Mbps video streaming + 100 Mbps Ethernet) without CPU polling overhead via burst transfers and DMA-ready interfaces. |
Use Scenario: An ultraportable notebook uses a modular expansion bay accepting either a second battery or dual PC Card adapters. IC Role / Device Role / Timing Role: PCI1520ZHK provides socket-level power control, card presence sensing, and ExCA-compliant register access - abstracting hardware complexity from OS drivers. Use Value: Supports seamless runtime insertion/removal of 16-bit or CardBus cards under Windows ACPI power states, with automatic resource reconfiguration and LED activity feedback. |
| Industrial Data Acquisition System | Legacy PCI-Based Test Equipment |
Use Scenario: A rack-mounted DAQ chassis uses PCI1520ZHK to host calibrated sensor interface cards (e.g., thermocouple, strain gauge) in ruggedized PC Card form factor. IC Role / Device Role / Timing Role: Acts as deterministic low-latency bridge with programmable interrupt routing (parallel PCI or serialized IRQSER), ensuring precise timestamp alignment between PCI host and card peripherals. Use Value: Delivers sub-microsecond interrupt latency and guaranteed 33-MHz PCI cycle timing - critical for synchronized multi-channel sampling at >100 kS/s. |
Use Scenario: A semiconductor ATE platform upgrades aging ISA-based instrumentation modules using PCI-hosted CardBus adapters. IC Role / Device Role / Timing Role: PCI1520ZHK serves as register-compatible drop-in replacement for Intel 82365SL-DF controllers - preserving existing BIOS, driver, and test firmware.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CardBus-to-PCI bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI PCI1510ZHK | Single-slot variant; lacks second socket interface, reduced memory/I/O window count, no ZV support | Suitable only for cost-sensitive single-card applications; cannot replace dual-socket functionality | Select PCI1510ZHK only when system requires exactly one CardBus slot and lower gate count is prioritized |
| Intel 82365SL-DF | No integrated LDO-VR (requires external 2.5-V supply); no ZV support; older 0.35-µm process; lower max throughput (~90 Mbps) | Legacy design continuity; limited to 16-bit PC Card only; no native CardBus burst acceleration | Choose 82365SL-DF only for strict register-identical replacement where PCI1520ZHK's advanced features are unused |
Compared with PCI1520ZHK, PCI1510ZHK reduces socket count and feature set for lower cost, while 82365SL-DF trades integration and performance for legacy compatibility - making PCI1520ZHK the optimal choice for new dual-slot, mixed-voltage, high-throughput CardBus designs requiring ZV and ACPI support.

FAQ
What is the primary function of the PCI1520ZHK?
The PCI1520ZHK is a dual-slot CardBus-to-PCI bridge controller that enables PCI hosts to interface with both 16-bit PC Cards and 32-bit CardBus cards. It handles voltage translation, hot-swap detection, ExCA register mapping, and burst-mode data transfers. The PCI1520ZHK integrates an LDO-VR for 2.5-V core supply and supports ACPI-compliant power management - making it ideal for notebook docking and industrial expansion systems.
Does the PCI1520ZHK require an external 2.5-V power supply?
No. The PCI1520ZHK includes an integrated low-dropout voltage regulator (LDO-VR) that generates its 2.5-V core supply from the 3.3-V I/O rail (VCC_IO). This eliminates the need for an external 2.5-V source, simplifying power design and reducing BOM cost. The LDO-VR is explicitly documented in Section 3.8.1 of the SCPS065D data manual.
Is the PCI1520ZHK pin-compatible with the Intel 82365SL-DF?
No - the PCI1520ZHK uses a 209-ball MicroStar BGA (ZHK) package, while the 82365SL-DF uses a 144-pin PQFP. However, the PCI1520ZHK is register-compatible with the 82365SL-DF and 82365SL, meaning software drivers and ExCA register access patterns remain identical. Hardware redesign is required for physical replacement due to differing packages and ball/pin counts.
What does "ZHK" signify in the part number PCI1520ZHK?
"ZHK" denotes the MicroStar BGA package variant of the PCI1520, specifying a 209-ball grid array with 0.8-mm pitch and thermal-enhanced construction. It is distinct from the PDV (208-terminal LQFP) variant. TI's ordering information confirms ZHK = PBGA package, and Figure 2−2 and Table 2−2 in SCPS065D validate terminal assignments specific to the GHK/ZHK footprint.
Does the PCI1520ZHK support Zoomed Video (ZV) functionality?
Yes. The PCI1520ZHK implements full hardware support for the Zoomed Video interface per PC Card Standard Rev. 7.1, including dedicated ZVCLK, ZVSYNC, and ZVDATA[7:0] signals and standardized ZV register model access. Section 3.5.4 and Table 3−3 in SCPS065D confirm ZV output functionality and signal timing - enabling direct video capture/playback offload without host CPU intervention.
