PCI1620PDV

Controllers Overview

The Texas Instruments PCI1620PDV is an obsolete dual-socket PC Card and UltraMedia controller integrated into a 208-pin LQFP package. It functions as a three-function PCI device compliant with PCI Local Bus Specification 2.2, providing two independent PC Card socket controllers adhering to PC Card Standard 8.0 and a firmware loading interface. The component supports serialized IRQs, PCI Power Management Interface Specification 1.1, and Advanced Configuration and Power Interface (ACPI) Specification 1.0. It features a serial EEPROM interface for subsystem identification and dedicated terminals for PCI CLKRUN. The internal architecture includes an integrated voltage regulator generating 1.8-V core logic from 3.3-V I/O cells, enabling compatibility with 5-V, 3.3-V, and 1.8-V cards.

Controllers Feature Summary

• Dual independent PC Card socket controllers supporting hot insertion and removal of 16-bit, CardBus, and UltraMedia cards
• Integrated voltage regulator allowing operation with 1.8-V core logic and 3.3-V I/O signaling environments
• Advanced filtering on card detect lines providing noise immunity and support for external zoomed video
• Serial interface compatibility with TI TPS2226 and TPS2228 power switches for system power management

Controllers Applications

• Bridging between the PCI bus and PC Cards in high-volume PC applications
• UltraMedia Flash media and Smart Card adapter implementations
• Systems requiring mix-and-match 5-V/3.3-V 16-bit PC Cards and 3.3-V CardBus slots

Controllers Procurement Notes

Verify the obsolete status of the PCI1620PDV before initiating any design or procurement activities. Confirm that the specific 208-pin LQFP package variant meets all mechanical and electrical requirements for the target application. Review the manufacturer's standard warranty terms and disclaimers regarding critical applications. Ensure compliance with RoHS and environmental classifications defined in the latest packaging information addendum.

Controllers Selection Notes

Select this component only if the design requires a dual-socket PC Card controller with integrated voltage regulation for 1.8-V core operation. Verify that the host system utilizes a PCI bus compliant with Specification 2.2 and supports the required interrupt modes. Evaluate the need for UltraMedia controller functionality alongside standard PC Card sockets. Consider the availability of qualified drivers for Smart Card adapters and ATA drivers for FlashMedia applications.

Controllers Part Context

The PCI1620 series serves as an I/O controller interface IC designed for PC Card, Flash, and Smart Card control within embedded processors and microcontroller systems. It bridges legacy PC Card standards with modern PCI bus architectures. The PDV suffix specifically denotes the 208-pin Low Profile Quad Flat Package variant, distinct from the BGA packages used in other series members like the GHK.

Controllers Replacement Considerations

The PCI1620PDV is listed as obsolete. No public confirmed substitute part numbers are documented in the provided source material.
