PCI2050BPPM集成電路（IC）的專用規(guī)格書PDF中文資料

PCI2050BPPM屬于集成電路（IC）的專用。由美國德州儀器公司制造生產(chǎn)的PCI2050BPPM專用該系列產(chǎn)品可提供所需的功能，用以將信息源/信宿連到各種復(fù)雜或范圍狹窄應(yīng)用中的傳感器、變送器、致動器、傳輸介質(zhì)或其他此類端點(diǎn)。例如，汽車安全氣囊驅(qū)動器、車身控制和信息娛樂總線、自適應(yīng)電纜均衡器、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
