Product details
Overview
PCI1420PDV from Texas Instruments is a PCI-to-CardBus bridge controller supporting two independent PC Card/CardBus sockets, featuring pipelined architecture for >130 Mbps throughput, 208-pin LQFP (PDV) package, 3.3-V core logic with universal 3.3-V/5-V PCI interface compatibility, and ExCA register mapping in memory and I/O space.
For engineers reviewing the PCI1420PDV datasheet, PCI1420PDV pinout, PCI1420PDV application, or PCI1420PDV equivalent, key selection considerations include hot-insertion support for mixed 5-V/3.3-V 16-bit PC Cards and 32-bit CardBus cards, distributed DMA capability, programmable CLKRUN output, and Intel 82365SL register compatibility in notebook/desktop host designs.
Technical Context
The PCI1420PDV implements a dual-socket bridge with separate ExCA configuration spaces per socket, enabling independent power management and interrupt routing for each slot. It supports both PCI master and slave operation, initiating bus mastering during 16-bit PC Card DMA or CardBus bridging transactions.
Its internal data path handles 8-, 16-, and 32-bit card accesses using full 32-bit PCI cycles, with independent buffering and pipeline architecture sustaining burst transfers. Low-power modes-including suspend states coordinated via PCI CLKRUN and CardBus CCLKRUN-align with PCI Bus Power Management Interface Specification compliance.

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 |
|---|---|---|---|
| PCI1410PDV | Single-socket variant with identical PDV package, reduced I/O window count (3 memory + 1 I/O per socket), no CLKRUN# programmability | Limited to cost-sensitive single-slot designs; lacks dual-socket hot-swap coordination and distributed DMA | Select when only one CardBus socket is needed and BOM cost reduction outweighs flexibility loss |
| PCI1520GHK | 209-pin MicroStar BGA package (GHK), supports same dual-socket functionality but requires different PCB layout and reflow profile | BGA footprint increases routing density and thermal management complexity; not drop-in replaceable for PDV-based designs | Choose for space-constrained layouts where BGA placement enables shorter trace lengths and improved signal integrity |
Compared with PCI1420PDV, PCI1410PDV reduces socket count and feature set for lower-cost implementations, while PCI1520GHK offers identical functionality in a BGA form factor-neither is pin-compatible, requiring board redesign, but both serve overlapping system-level roles in PCI-hosted CardBus expansion.

FAQ
What is the primary function of the PCI1420PDV in a host system?
The PCI1420PDV serves as a dual-socket PCI-to-CardBus bridge controller, enabling communication between a PCI host bus and two independent PC Card or CardBus peripherals. It manages ExCA-compliant configuration, power sequencing, hot insertion/removal, and DMA transfers. The PCI1420PDV integrates all necessary logic to support mixed 5-V/3.3-V 16-bit cards and 3.3-V 32-bit CardBus cards without external interface components.
Does the PCI1420PDV support both PCI master and slave operation?
Yes, the PCI1420PDV operates in both PCI master and slave modes. As a slave, it responds to PCI configuration and memory-mapped I/O reads/writes from the host. As a master, it initiates PCI bus transactions during 16-bit PC Card DMA transfers or CardBus bridging operations. This dual-mode capability allows flexible integration into diverse host architectures while maintaining full compliance with PCI Local Bus Specification Rev 2.2.
How does the PCI1420PDV handle hot insertion and removal of PC Cards?
The PCI1420PDV provides full hardware-level hot insertion and removal support through internal signal buffering and ExCA-compliant socket control logic. All card-facing signals-including VCC, VPP, and I/O lines-are buffered on-die to meet PC Card Standard electrical requirements. The PCI1420PDV monitors card presence, voltage status, and readiness signals autonomously, eliminating need for external hot-swap controllers or discrete protection circuitry in compliant designs.
What package type and RoHS status does the PCI1420PDV use?
The PCI1420PDV uses a 208-pin Low-Profile Quad Flat Package (LQFP) with PDV drawing, RoHS-compliant finish (Cu/NiPdAu), and moisture sensitivity level (MSL) rating of Level-1 (260°C, unlimited floor life). It is designated as Green (RoHS & no Sb/Br) per TI's eco-plan, meaning it contains no bromine- or antimony-based flame retardants and meets all six RoHS substance restrictions, including lead ≤0.1% by weight.
Is the PCI1420PDV pin-compatible with Intel 82365SL controllers?
No, the PCI1420PDV is not pin-compatible with Intel 82365SL controllers due to differing package types (208-pin LQFP vs. 128-pin PQFP) and expanded signal set including CLKRUN#, LED outputs, and additional general-purpose I/Os. However, it is fully register-compatible with Intel 82365SL-DF and 82365SL ExCA implementations, allowing reuse of existing driver software and configuration space access logic in host systems.
