Product details
Overview
PCI1620PDV from Texas Instruments is a dual-socket PC Card and UltraMedia™ controller implementing three PCI functions: two independent PC Card socket controllers (Functions 0 & 1) and a firmware loader interface (Function 2). It supports 16-bit PC Cards, CardBus, SmartMedia™, SD, MultiMediaCard, Memory Stick™, and Smart Card adapters with 1.8-V core / 3.3-V I/O, PCI 2.2 compliance, and ExCA register compatibility for legacy system integration in notebook and embedded host platforms.
For engineers reviewing the PCI1620PDV datasheet, PCI1620PDV pinout, PCI1620PDV application, or PCI1620PDV equivalent, key selection considerations include its dual-socket CardBus/PC Card bridging capability, integrated voltage regulation, serial EEPROM configuration interface, ACPI-compliant multifunction terminals, and support for hot insertion/removal of mixed-voltage cards without host driver changes.
Technical Context
The PCI1620PDV implements a PCI-to-CardBus bridge architecture compliant with PC Card Standard 8.0 and PCI Local Bus Specification Revision 2.2. It provides separate configuration spaces per socket, supports serialized IRQ and PCI LOCK, and delivers 132-MBps burst transfers via pipelined data path logic with independent buffering.
Its internal architecture includes an integrated 1.8-V regulator for core logic, 3.3-V I/O cells, and a three-terminal serial interface compatible with TI TPS2226/TPS2228 power switches. Four general-purpose event registers and seven programmable multifunction terminals enable platform-specific ACPI event handling, LED control, suspend signaling, and PCI CLKRUN management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PC Card and UltraMedia controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCI1620GHK | BGA-209 package; identical electrical and functional specification; different thermal and mechanical footprint | Preferred for space-constrained designs where LQFP layout is impractical; requires BGA rework capability | Select GHK for high-density PCBs; PDV remains optimal for prototyping and manual assembly due to LQFP visibility and reworkability |
| PCI1620ZHK | BGA-209 package with alternate ball map; functionally identical but incompatible pinout vs. GHK/PDV | Used in specific TI reference designs with custom carrier boards; not interchangeable without board redesign | ZHK is not a drop-in alternative; choose only if matching original equipment manufacturer's board layout and firmware calibration |
Compared with PCI1620PDV, the GHK offers identical functionality in a smaller BGA form factor suitable for volume production, while ZHK requires full board redesign due to non-compatible ball mapping - making PDV the only option for legacy-compatible LQFP-based upgrades and evaluation.

FAQ
What is the primary function of the PCI1620PDV in a host system?
The PCI1620PDV serves as a dual-socket PCI-to-CardBus bridge and UltraMedia controller, enabling host systems to interface with 16-bit PC Cards, CardBus peripherals, SmartMedia™, SD, MultiMediaCard, Memory Stick™, and Smart Card adapters. Its three-function PCI architecture - two independent socket controllers plus a firmware loader - allows seamless integration without modifying existing ExCA-compliant host drivers. The PCI1620PDV is essential for expanding legacy PCI platforms with modern flash media and secure authentication capabilities.
Does the PCI1620PDV support hot insertion and removal of PC Cards?
Yes, the PCI1620PDV fully supports hot insertion and removal of PC Cards and CardBus devices through hardware-level detection circuitry including advanced filtering on card detect lines (CD1#, CD2#) providing 90 µs noise immunity. This ensures reliable real-time card presence sensing without false triggers. The PCI1620PDV works with standard PC Card service software and requires no host driver modifications - a key feature confirmed in TI's SLLA234 datasheet and validated in notebook and industrial embedded implementations using the PCI1620PDV.
What voltage levels does the PCI1620PDV support for core logic and I/O interfaces?
The PCI1620PDV uses a 1.8-V core logic supply generated internally by an integrated voltage regulator, while its I/O cells operate at 3.3 V for PCI bus signaling and PC Card interface compatibility. It also supports external 1.8-V card power delivery via a three-terminal serial interface compatible with TI TPS2226 and TPS2228 dual power switches. This dual-rail architecture enables direct interfacing with 5-V, 3.3-V, and 1.8-V cards across both sockets - a capability explicitly documented in the PCI1620PDV datasheet and critical for mixed-voltage expansion systems.
Is the PCI1620PDV pin-compatible with the Intel 82365SL–DF controller?
The PCI1620PDV is ExCA register compatible with the Intel 82365SL–DF, meaning it maps control registers identically in memory or I/O space and supports the same host interface defined in the PC Card Standard. However, it is not pin-compatible - the PCI1620PDV is a 208-pin LQFP device with distinct pin assignments for CLKRUN#, SUSPEND#, RI#, and multifunction terminals absent in the older Intel part. System migration requires PCB layout changes but preserves full software compatibility, as confirmed in TI's SLLA234 application report for the PCI1620PDV.
What types of UltraMedia cards does the PCI1620PDV support?
The PCI1620PDV supports SmartMedia™, SD, MultiMediaCard, Memory Stick™, and Smart Card adapters through its integrated UltraMedia™ controller. It enables passive 4-in-1 adapters as well as active PC Card-style flash media solutions, all using existing host ATA drivers for storage and TI-provided qualified drivers for Smart Card functions. This multi-format support is built into the PCI1620PDV's firmware and data path logic - eliminating need for external controllers - and is verified in TI's official documentation, including the SLLA234 datasheet revision dated June 2006.
