PCI2050BPDV集成电路（IC）的专用规格书PDF中文资料

PCI2050BPDV属于集成电路（IC）的专用。由德州仪器制造生产的PCI2050BPDV专用该系列产品可提供所需的功能，用以将信息源/信宿连到各种复杂或范围狭窄应用中的传感器、变送器、致动器、传输介质或其他此类端点。例如，汽车安全气囊驱动器、车身控制和信息娱乐总线、自适应电缆均衡器、智能卡等等。

1.1 Features

The PCI2050B bridge supports the following features:

• Two 32-bit, 66-MHz PCI buses

• 3.3-V core logic with universal PCI interfaces compatible with 3.3-V and 5-V PCI signaling environments

• Internal two-tier arbitration for up to nine secondary bus masters and supports an external secondary bus

arbiter

• Ten secondary PCI clock outputs

• Independent read and write buffers for each direction

• Burst data transfers with pipeline architecture to maximize data throughput in both directions

• Supports write combing for enhanced data throughput

• Up to three delayed transactions in both directions

• Supports the frame-to-frame delay of only four PCI clocks from one bus to another

• Bus locking propagation

• Predictable latency per PCI Local Bus Specification

• Architecture configurable for PCI Bus Power Management Interface Specification

• CompactPCI hot-swap functionality

• Secondary bus is driven low during reset

• VGA/palette memory and I/O decoding options

• Advanced submicron, low-power CMOS technology

• 208-terminal PDV, 208-terminal PPM, or 257-terminal MicroStar BGA™ package
