Product details
Overview
PCI1520IZHK from Texas Instruments is a dual-slot PCI-to-CardBus bridge controller in 209-ball MicroStar BGA (GHK) 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 in notebook docking stations.
For engineers reviewing the PCI1520IZHK datasheet, PCI1520IZHK pinout, PCI1520IZHK application, or PCI1520IZHK equivalent, this page delivers verified technical context, confirmed pin functions per GHK package, real-world power management register behavior, and validated alternative controllers for PC Card subsystem design.
Technical Context
The PCI1520IZHK implements a register-compatible ExCA-compliant bridge with two independent socket interfaces-each supporting full CardBus 32-bit/33-MHz operation and legacy 16-bit PC Card mode. Its internal data path handles 8-/16-/32-bit card accesses via 32-bit PCI cycles, with burst transfers enabling sustained >130 Mbps throughput in both directions.
It integrates an LDO-VR for on-chip 2.5-V core generation, supports multiple interrupt delivery methods (parallel PCI, serialized ISA/PCI), includes five general-purpose I/Os, and features dedicated terminals for socket activity LEDs, ring indication (RI_OUT), CLKRUN control, and TPS222X power-switch interface-all while maintaining Intel 82365SL-DF/SL register compatibility.

Applications
| Mobile Docking Station | Notebook Expansion Bay |
|---|---|
Use Scenario: A laptop dock provides simultaneous connectivity for legacy 16-bit modems and high-speed 32-bit CardBus Ethernet adapters.

IC Role / Device Role / Timing Role: PCI1520IZHK serves as the host-side bridge controller, handling PCI enumeration, CardBus BAR decoding, and socket event interrupts. Use Value: Integrated LDO-VR simplifies power design; CLKRUN# support reduces idle power consumption during bay disconnection. |
| Industrial PCMCIA Host | Legacy System Upgrade Module |
Use Scenario: An industrial embedded controller adds field-replaceable I/O modules via ruggedized CardBus sockets. IC Role / Device Role / Timing Role: PCI1520IZHK provides register-compatible ExCA interface for Linux PCMCIA subsystem drivers and manages socket-level power sequencing. Use Value: Intel 82365SL-DF register compatibility ensures drop-in driver support; RI_OUT and LED outputs simplify status monitoring. |
Use Scenario: A desktop motherboard upgrade kit replaces aging ISA-based peripherals with modern CardBus alternatives. IC Role / Device Role / Timing Role: PCI1520IZHK bridges legacy PCI bus to new CardBus peripherals, translating PCI memory/I/O cycles into CardBus command sequences.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-CardBus bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI PCI1510IZHK | Single-slot variant; lacks second socket interface and associated registers; identical GHK package and core logic | Not suitable for dual-socket systems; limited to single-card applications like compact expansion modules | Select PCI1510IZHK only when board space or cost constraints eliminate need for dual-socket support |
| Intel 82365SL-DF | No integrated LDO-VR; requires external 2.5-V supply; same ExCA register map and pinout (PDV package only) | Requires additional power component; incompatible pinout prevents direct PCB replacement for GHK-based designs | Choose 82365SL-DF only if existing PDV-layout infrastructure and external 2.5-V supply are already in place |
Compared with PCI1520IZHK, the PCI1510IZHK reduces socket count and feature set for cost-sensitive single-card use cases, while the 82365SL-DF demands external core regulation and offers no BGA option-making PCI1520IZHK the sole GHK-packaged, self-regulated dual-socket bridge in its class.

FAQ
What is the package type and ball count for PCI1520IZHK?
The PCI1520IZHK uses a 209-ball MicroStar BGA (GHK) package with 0.8-mm ball pitch and 17 × 17 array layout. This differs from the 208-terminal LQFP (PDV) variant. Pin functions are fully documented in Figure 2−1 and Table 2−2 of the SCPS065D data manual, and all 209 terminals are electrically validated for GHK-specific routing.
Does PCI1520IZHK require an external 2.5-V power supply?
No. The PCI1520IZHK integrates a low-dropout voltage regulator (LDO-VR) that generates the 2.5-V core supply internally from the 3.3-V I/O rail. This eliminates the need for an external 2.5-V source, reducing bill-of-materials count and improving power rail stability-confirmed in Section 3.8.1 and Table 7−2 of SCPS065D.
Is PCI1520IZHK compatible with Intel 82365SL-DF drivers?
Yes. The PCI1520IZHK is register-compatible with the Intel 82365SL-DF and 82365SL ExCA controllers, meaning standard PC Card drivers-including Linux pcmcia-cs and Windows CE ExCA stacks-operate without modification. However, physical pinout differs: 82365SL-DF uses PDV (LQFP), not GHK (BGA), so PCB replacement is not possible.
How does PCI1520IZHK support hot insertion and removal of PC Cards?
The PCI1520IZHK provides internal 3-state bidirectional buffering on all card signals, eliminating need for external transceivers. Hot-swap safety is enforced through GRST-driven initialization, dedicated card-detect logic (Section 3.5.1), and ExCA register-based event masking-ensuring clean enumeration and safe power sequencing during live card changes.
What interrupt delivery methods does PCI1520IZHK support?
The PCI1520IZHK supports four interrupt delivery modes: parallel PCI (INTA#–INTD#), serialized PCI (IRQSER), parallel ISA (IRQ0–IRQ15), and serialized ISA (IRQSER). These are configured via the Interrupt Pin Register (Section 4.24) and Interrupt Mask/Flag Registers (Table 3−9), allowing flexible integration with host interrupt controllers in diverse platform architectures.
