Product details
Overview
The PCI1520PDVG4 from Texas Instruments is a dual-slot PCI-to-CardBus bridge controller in a 208-pin LQFP (PDV) package, implementing full 32-bit PCI v2.2 and PC Card Standard rev. 7.1 compliance. It supports hot insertion/removal of mixed 16-bit PC Cards (5 V/3.3 V) and 32-bit CardBus cards (3.3 V only), delivers ≥130 Mbps sustained burst throughput, and integrates an LDO-VR for 2.5-V core supply - enabling direct use with standard 3.3-V system rails in notebook docking stations and industrial expansion modules.
For engineers reviewing the PCI1520PDVG4 datasheet, PCI1520PDVG4 pinout, PCI1520PDVG4 application, or PCI1520PDVG4 equivalent, this page provides verified technical context on its ExCA register compatibility, PCI/CardBus dual-master/slave operation, power management (ACPI/PME), serial EEPROM interface, and socket-level interrupt routing - all critical for legacy PC Card subsystem design and migration.
Technical Context
The PCI1520PDVG4 implements a pipelined, buffered data path supporting concurrent 8-/16-/32-bit card access over full 32-bit PCI cycles, with independent buffering per socket to enable true hot-swap without external logic. Its register set is fully compatible with Intel 82365SL-DF/82365SL ExCA controllers, mapping configuration space, CardBus socket registers, and power-management registers into both memory and I/O address spaces.
It integrates a 2.5-V LDO-VR, internal ring oscillator, programmable CLKRUN output, and five general-purpose I/Os. Power management includes PCI PME, Suspend Mode, Clock Run Protocol, and CardBus-specific ACPI support - all coordinated via dedicated PM control/status registers and socket event masking.

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 PCI1510PZG4 | Single-slot variant; identical PDV package, register set, and LDO-VR; lacks second socket interface logic and associated pins. | Suitable only for systems requiring one CardBus slot; lower pin count and reduced PCB routing complexity. | Select PCI1510PZG4 when dual-socket functionality is unnecessary - reducing cost and board area while retaining driver compatibility. |
| Intel 82365SL-DF | No integrated LDO-VR; requires external 2.5-V supply; identical ExCA register map and socket control logic; 208-pin PQFP package. | Requires additional power component and tighter voltage tolerance; otherwise functionally interchangeable in legacy designs. | Choose 82365SL-DF only if existing board already provides 2.5-V rail - avoiding redesign but increasing BOM and thermal overhead vs. PCI1520PDVG4. |
Compared with PCI1510PZG4 and 82365SL-DF, the PCI1520PDVG4 uniquely combines dual-socket support, integrated 2.5-V regulation, and identical ExCA compatibility - delivering higher functional density and lower system-level power design effort without sacrificing driver reuse.

FAQ
What is the primary function of the PCI1520PDVG4 in a system architecture?
The PCI1520PDVG4 serves as a dual-slot PCI-to-CardBus bridge controller, enabling host systems with a PCI bus to interface with both legacy 16-bit PC Cards and modern 32-bit CardBus peripherals. It handles protocol translation, power management, hot-swap detection, and register-level compatibility with Intel's ExCA specification - making it essential for docking stations, expansion modules, and embedded platforms requiring flexible peripheral connectivity.
Does the PCI1520PDVG4 require an external 2.5-V power supply?
No, the PCI1520PDVG4 integrates a low-dropout voltage regulator (LDO-VR) that generates its 2.5-V core supply from the 3.3-V I/O rail. This eliminates the need for an external 2.5-V regulator, simplifying power design and reducing bill-of-materials cost - a key differentiator versus alternatives like the Intel 82365SL-DF.
Is the PCI1520PDVG4 pin-compatible with the Intel 82365SL-DF?
The PCI1520PDVG4 shares the same 208-pin LQFP (PDV) footprint and signal assignment as the Intel 82365SL-DF, enabling mechanical drop-in replacement. However, the PCI1520PDVG4 includes integrated LDO-VR functionality not present in the 82365SL-DF - requiring minor power rail adjustments if substituting in an existing 82365SL-DF design.
How does the PCI1520PDVG4 support hot insertion and removal of PC Cards?
The PCI1520PDVG4 internally buffers all card signals with ESD protection and implements ExCA-compliant socket event detection, power switching control (via TPS222X interface), and status monitoring. Its GRST-driven initialization sequence ensures safe enumeration after card insertion, while dedicated LED outputs provide visual activity feedback - all without requiring external buffer ICs or glue logic.
What interrupt configurations does the PCI1520PDVG4 support?
The PCI1520PDVG4 supports four interrupt modes: parallel PCI (INTA#/INTB#), serialized PCI (SERIRQ), parallel ISA (IRQx), and serialized ISA (SERIRQ). These are configured via ExCA and PCI configuration registers, allowing flexible integration into diverse host interrupt architectures - from legacy x86 systems to modern embedded controllers with limited IRQ resources.
