Product details
Overview
PCI1031PDV from Texas Instruments is a PCI-to-PC Card16 controller IC supporting two independent 16-bit PC Card sockets compliant with the 1995 PC Card standard, operating at 33 MHz PCI clock rate, with 3.3-V core logic and dual-voltage (3.3-V/5-V) PC Card signaling, used in notebook and desktop systems for legacy PC Card expansion.
For engineers reviewing the PCI1031PDV datasheet, PCI1031PDV pinout, PCI1031PDV application, or PCI1031PDV equivalent, key selection concerns include PCI Local Bus Specification 2.1 compliance, ExCA register compatibility, Intel 82365SL-DF register mapping, hot-insertion support per socket, and Zoom Video mode enablement via 23-pin redefinition on each 68-pin PC Card interface.
Technical Context
The PCI1031PDV implements a dual-socket bridge architecture with separate configuration spaces for each PC Card slot, enabling independent memory and I/O window allocation: five PCI memory windows and two I/O windows per socket. Its internal datapath supports full 32-bit PCI cycles for 8-/16-bit card access and includes independent 32-bit write buffers for posted writes.
It integrates multifunction interrupt handling-supporting both PCI-style (INTA/INTB) and ISA-style (IRQ3–IRQ15) interrupts-with programmable serialization via IRQSER, and provides TI extension registers mapped in PCI configuration space alongside ExCA registers mapped in memory/I/O space. Power management includes SUSPEND mode preserving register state during RSTIN assertion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCI-to-PC Card16 controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCI1030PDV | Single-socket variant; lacks second PC Card interface and associated I/O/memory windows. | Not suitable for dual-card systems; lower pin count (160-pin TQFP) and reduced feature set (no Zoom Video, no IRQSER). | Select only when cost-sensitive designs require exactly one PC Card slot and omit ZV/serialization needs. |
| PCI1131PDV | Enhanced revision with improved power management, extended ExCA register set, and added CardBus support (32-bit, 33 MHz). | Backward-compatible but adds CardBus capability; requires updated BIOS/driver support for new features. | Choose for future-proofing where CardBus migration path is planned, but verify legacy driver compatibility. |
Compared with PCI1031PDV, PCI1030PDV sacrifices socket count and advanced features for cost reduction, while PCI1131PDV extends functionality toward CardBus without compromising 16-bit PC Card support-making PCI1031PDV optimal for pure dual-socket 16-bit legacy expansion.

FAQ
What is the primary function of the PCI1031PDV in a system architecture?
The PCI1031PDV serves as a dual-socket PCI-to-PC Card16 bridge controller, translating PCI bus transactions into 16-bit PC Card protocol for two independent sockets. It handles address decoding, data buffering, interrupt routing, and power sequencing-enabling legacy PCMCIA peripherals to operate seamlessly on modern PCI-based motherboards without requiring changes to host firmware or drivers.
Does the PCI1031PDV support both 3.3-V and 5-V PC Cards simultaneously?
Yes, the PCI1031PDV supports mix-and-match 3.3-V and 5-V PC Cards across its two sockets. VCCA supplies Socket A and VCCB supplies Socket B independently, allowing one socket to power a 3.3-V modem card while the other powers a 5-V flash memory card-each with appropriate level-shifting and hot-swap protection built into the controller's I/O circuitry.
How does the PCI1031PDV implement Zoom Video (ZV) mode?
The PCI1031PDV implements Zoom Video mode by redefining 23 pins on each 68-pin PC Card interface to carry ZV-specific signals (e.g., ZVCLK, ZVDATA[7:0], ZVSYNC) instead of standard PC Card address/data lines. This occurs only when ZV mode is enabled via TI extension registers, allowing direct routing of uncompressed video frames from PC Card to VGA controller without intermediate buffering or CPU intervention.
What is the role of the IRQ9/IRQSER pin on the PCI1031PDV?
The IRQ9/IRQSER pin on the PCI1031PDV is a dual-function terminal: configured as IRQ9, it delivers standard ISA-style interrupts from PC Cards to the system PIC; configured as IRQSER, it serializes multiple PC Card interrupt requests (e.g., from Socket A and Socket B) onto a single wire using TI's proprietary serialization protocol-reducing interrupt pin count and simplifying board-level interrupt routing.
Is the PCI1031PDV pin-compatible with the Intel 82365SL-DF controller?
Yes, the PCI1031PDV is register-compatible with the Intel 82365SL-DF PC Card interface controller, meaning software drivers written for the 82365SL-DF can operate unchanged with the PCI1031PDV. However, physical pinout differs due to PCI interface integration and dual-socket support-requiring PCB redesign despite functional driver compatibility.
