The PCI9050REV1 is a 32-bit PCI Local Bus Target/Initiator interface controller from PLX Technology. It acts as a bridge between a local bus and the PCI bus, enabling devices on the local bus to communicate with the PCI bus. This controller is commonly used in embedded systems, data acquisition systems, and industrial control applications where a PCI interface is required.

Applications:

• Data Acquisition Systems
• Industrial Control Systems
• Embedded Systems with PCI connectivity
• Peripheral expansion cards
• Legacy ISA or EISA bus to PCI conversion

Features:

• 32-bit PCI Target/Initiator
• Supports PCI Rev 2.1
• Local bus interface (can be configured for different bus widths)
• DMA support
• Interrupt controller
• EEPROM interface for configuration data

Benefits:

• Easy PCI Integration: Simplifies the process of connecting a local bus device to a PCI bus.
• High Performance: Supports DMA for efficient data transfer between the local bus and the PCI bus.
• Flexibility: Configurable local bus interface allows it to be adapted to different system architectures.
• Reduced Development Time: Provides a complete PCI interface solution, reducing the need for custom hardware and software development.
• Cost-Effective: Integrated features such as DMA and interrupt controller reduce the need for external components.

Detailed Information:

The PCI9050REV1 provides a seamless bridge between a local bus and the PCI bus. It supports both target and initiator functionality, allowing the local device to act as either a slave or a master on the PCI bus. The DMA controller enables high-speed data transfers without CPU intervention, improving system performance. The interrupt controller manages interrupts from the local device and forwards them to the PCI bus.

Technical Specifications:

• PCI Interface: 32-bit, 33 MHz, PCI Rev 2.1 compliant
• Local Bus Interface: Configurable bus width (8, 16, or 32 bits)
• DMA Channels: Supports multiple DMA channels
• Interrupt Controller: Programmable interrupt controller
• EEPROM Interface: Supports serial EEPROM for configuration storage
• Operating Voltage: 3.3V or 5V
• Package: Typically available in a PQFP or PLCC package

The PCI9050REV1 is a versatile and widely used PCI interface controller that simplifies the integration of local bus devices into PCI-based systems. Its flexible architecture, DMA support, and integrated features make it an ideal choice for a variety of embedded and industrial applications.
