EC140 64-bit PCI Target

See EC125 for 32-bit PCI Target

Features

• Fully supports PCI specification 2.1 and 2.2 protocol.
• Supports both 64-bit and 32-bit bus systems.
• Supports dual address cycle (DAC) 64-bit addressing.
• Designed for ASIC and PLD implementations.
• Fully static design with edge triggered flip-flops.
• Combined bus master and target functions.
• Efficient back-end interface for different types of bus slave and master devices.
• Zero wait state burst data transfer.
• Automatic transfer restart on target retry and disconnect.
• High speed bus request and arbitration.
• Parity generation and parity error detection.
• Includes all PCI specific configuration registers.
• Optimized for devices with slow output enable control.

Differentiating Features

• Multiple base address registers.
• Address and data multiplexing.
• Dual address cycle
• Asynchronous clock domain.
• Direct FIFO interface.
