PCI1515ZHK

Controllers Overview

The Texas Instruments PCI1515 is a single-socket PC Card controller compliant with PCI Local Bus Specification Revision 2.3 and the PC Card Standard Release 8.1. It supports 16-bit, CardBus, and USB custom cards powered at 5 V or 3.3 V. The device features an internal data path allowing host access to 8-, 16-, and 32-bit cards using full 32-bit PCI cycles. It includes an integrated low-dropout voltage regulator (LDO-VR) for core power supply management. The controller provides independent buffering and a pipeline architecture for sustained bursting performance.

Controllers Feature Summary

• Supports hot insertion and removal of PC Cards through internally buffered card signals without requiring external buffering components.
• Provides register compatibility with the Intel 82365SL-DF ExCA controller while offering enhanced performance via independent buffering and pipeline architecture.
• Integrates an LDO-VR for internal core power supply management and supports multiple low-power modes compliant with PCI Bus Power Management specifications.

Controllers Applications

• Bridging between the PCI bus and various PC Card types including 16-bit, CardBus, and USB custom interfaces.
• Implementing system-level power management strategies through ACPI-compliant programming interfaces and PCI power states.
• Utilizing multifunction terminals for platform-specific signals such as PCI LOCK, serial/parallel interrupts, and LED activity indicators.

Controllers Procurement Notes

Verify the specific package variant required, as the ZHK suffix denotes a particular physical form factor. Confirm that the design environment supports the necessary PCI and PC Card standards referenced in the datasheet. Ensure that the host system can accommodate the internal buffering requirements and power sequencing protocols defined by the controller's electrical characteristics.

Controllers Selection Notes

Select this component when a single-socket solution is required for bridging PCI buses to legacy or modern PC Card interfaces. Consider the internal buffering capabilities if external signal conditioning is to be minimized. Evaluate the need for integrated LDO-VR functionality versus external power regulation schemes based on system board space and thermal constraints.

Controllers Part Context

The PCI1515 serves as a high-performance bridge between the PCI local bus and PC Card sockets. It is designed to replace older discrete logic solutions or legacy controllers like the 82365SL-DF while maintaining register compatibility. The device integrates control logic, power management features, and signal buffering into a single chip to simplify motherboard or expansion card designs.

Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify register compatibility with the Intel 82365SL-DF if migrating from legacy designs, noting that the PCI1515 offers enhanced performance features beyond basic ExCA compatibility.
