Product details
Overview
PCI1420PDVG4 from Texas Instruments is a PCI-to-CardBus bridge controller supporting two independent PC Card/CardBus sockets, featuring pipelined architecture for >130 Mbps throughput, 3.3-V core logic with universal 3.3-V/5-V PCI interface compatibility, and register compatibility with Intel 82365SL-DF/SL ExCA controllers. It enables hot insertion/removal of mixed 5-V/3.3-V 16-bit PC Cards and 32-bit CardBus cards in notebook and desktop systems.
For engineers reviewing the PCI1420PDVG4 datasheet, PCI1420PDVG4 pinout, PCI1420PDVG4 application, or PCI1420PDVG4 equivalent, key selection considerations include dual-socket ExCA register mapping, programmable CLKRUN output, distributed DMA support, 208-pin LQFP package constraints, and NRND status requiring supply continuity planning.
Technical Context
The PCI1420PDVG4 implements a full PCI Local Bus Specification-compliant interface acting as both PCI master (during 16-bit PC Card DMA or CardBus bridging) and slave, with support for fast posted writes to improve bus utilization. Its internal data path handles 8-, 16-, and 32-bit card accesses using full 32-bit PCI cycles.
It integrates Exchangeable Card Architecture (ExCA) registers mapped in both memory and I/O space, supports parallel/serial ISA and PCI interrupt signaling, and provides five PCI memory windows plus two I/O windows per R2 socket - all while maintaining internal buffering for hot-swap operation without external components.

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 |
|---|---|---|---|
| PCI1420PDV | Identical pinout, identical electrical specs, same PDV package; differs only in tape-and-reel packaging quantity (36 vs 36) and eco-plan labeling | No functional difference; used interchangeably in production where MSL Level-1 compliance is required | Select PCI1420PDV when sourcing from legacy inventory or distributor stock lacking G4 suffix marking |
| PCI1420GHK | 209-terminal MicroStar BGA package (GHK), different footprint and solder-reflow profile; same core functionality and register set | Requires PCB redesign due to BGA vs LQFP; preferred in space-constrained designs where thermal pad grounding improves EMI performance | Choose PCI1420GHK only when board layout allows BGA placement and thermal management supports 220°C peak reflow |
Compared with PCI1420PDVG4, PCI1420PDV offers identical functionality in the same LQFP package but without explicit G4 eco-labeling, while PCI1420GHK delivers equivalent bridge capability in a smaller BGA form factor at the cost of layout incompatibility and higher assembly complexity.

FAQ
What is the primary function of the PCI1420PDVG4 in a system architecture?
The PCI1420PDVG4 serves as a PCI-to-CardBus bridge controller, enabling communication between a host PCI bus and two independent PC Card or CardBus sockets. It translates protocols, manages voltage levels (5-V/3.3-V), handles hot insertion/removal, and provides ExCA-compliant register mapping. The PCI1420PDVG4 is essential for adding modular peripheral expansion to notebook and desktop platforms without requiring custom interface logic.
Is the PCI1420PDVG4 pin-compatible with Intel 82365SL-DF or 82365SL controllers?
Yes, the PCI1420PDVG4 is register-compatible with Intel 82365SL-DF and 82365SL ExCA controllers, meaning software drivers written for those devices can operate with minimal or no modification. However, it is not pin-compatible - the PCI1420PDVG4 uses a 208-pin LQFP package, whereas the Intel parts use different packages and pinouts. Hardware redesign is required for replacement.
Does the PCI1420PDVG4 support both 16-bit PC Cards and 32-bit CardBus cards simultaneously?
Yes, the PCI1420PDVG4 supports any combination of 16-bit PC Cards and 32-bit CardBus cards across its two sockets, including mixed-voltage operation (5-V and 3.3-V cards). Each socket independently negotiates card type and voltage, and the device handles protocol translation, arbitration, and timing alignment internally without host CPU involvement.
What power management features does the PCI1420PDVG4 implement per the PCI specification?
The PCI1420PDVG4 complies with the PCI Bus Power Management Interface Specification and provides dedicated signals including CLKRUN#, SUSPEND#, and CCLKRUN# for coordinated low-power state entry/exit. It supports D1/D2 device power states and enables dynamic clock gating, allowing the host system to reduce power consumption during idle periods while preserving socket readiness for hot insertion events.
Why is the PCI1420PDVG4 marked as NRND (Not Recommended for New Designs)?
The PCI1420PDVG4 is designated NRND by Texas Instruments because it targets legacy PC Card infrastructure that has been superseded by ExpressCard and USB-based expansion. While still in production to support existing customer designs, TI recommends newer alternatives for new projects. Aetrix Electronics maintains active inventory and supply continuity planning for PCI1420PDVG4 to support long-lifecycle industrial and medical equipment programs.
