PCI1512ZVF

Controllers Overview

The PCI1512ZVF is a single-slot CardBus controller manufactured by Texas Instruments, housed in a 216-terminal MicroStar BGA package. It serves as a high-performance bridge between the PCI bus and PC Cards, supporting both 16-bit PC Cards and 32-bit CardBus devices. The device operates with a 2.5-V core logic supply and supports 3.3-V or 5-V I/O signaling environments. It features a pipelined architecture enabling throughput exceeding 130 Mbps for bidirectional data transfers. The controller includes an integrated low-dropout voltage regulator (LDO-VR) to eliminate external power components and provides five general-purpose I/Os. It complies with the ExCA standard and is register-compatible with Intel 82365SL-DF and 82365SL controllers.

Controllers Feature Summary

• Supports hot insertion and removal of PC Cards without requiring external buffering due to internally buffered card signals.
• Provides flexible interrupt configuration options including parallel PCI, parallel ISA, serialized ISA, and serialized PCI modes.
• Features independent buffering and a pipelined architecture to maximize data throughput via burst transfers.
• Includes an integrated LDO-VR to simplify board design by removing the need for an external 2.5-V power supply.

Controllers Applications

• Bridging PCI buses to PC Cards in notebook computers
• Connecting PC Cards in desktop computer systems
• Implementing single-slot CardBus expansion solutions

Controllers Procurement Notes

Verify the current production status before design implementation, as the PCI1512ZVF is listed as NRND (Not Recommended for New Designs). Confirm that the 216-terminal MicroStar BGA package dimensions align with the target PCB layout constraints. Ensure compatibility with existing system BIOS and driver software for the specific interrupt and power management configurations required.

Controllers Selection Notes

Select this component when a single-slot solution is required for bridging PCI to PC Cards in legacy or specific industrial applications. It is suitable for designs needing register compatibility with Intel 82365SL controllers. Consider the NRND status and evaluate alternative newer generation controllers if new product development is intended. Verify support for both 3.3-V and 5-V PC Card power requirements.

Controllers Part Context

The PCI1512 is part of Texas Instruments' portfolio of interface controllers designed for PC peripheral connectivity. It specifically addresses the needs of CardBus and PC Card interfaces in computing platforms. The ZVF suffix denotes the specific 216-terminal MicroStar BGA packaging variant used for this device.

Controllers Replacement Considerations

As the PCI1512ZVF is marked NRND, verify availability through lifetime-buy periods or existing stock. Consult Texas Instruments for recommended successor devices or alternative single-slot CardBus controllers that offer active status and updated packaging options.
