mini pci-e针脚定义.doc

Mini PCI插槽也同样是在PCI插槽的基础上发展起来的，最初是应用于笔记本，现在不少台式机也配备了Mini PCI插槽。Mini PCI的定义与PCI基本上一致，只是在外型上进行了微缩。目前使用Mini PCI插槽的主要有内置的无线网卡、Modem网卡、电视卡以及一些多功能扩展卡等硬件设备。PCI 是 Peripheral Component Interconnect 的缩写接口卡的外观PCI 标准 32位/64位 接口卡 -| PCI 元件侧 （B面） | | | | _ 32 位引脚部分 64 位引脚部分 _|_| |-|-|-| b01 b11 b14 b49 b52 b62 b63 b94PCI 5V 32/64位卡| optional | _ 32 位引脚部分 64 位引脚部分 _|_| |-|-|PCI 3.3V 32/64位卡| optional | _ 32 位引脚部分 64 位引脚部分 _|_| |-|-|引脚定义 Pin +5V +3.3V Universal DescriptionA1 TRST Test Logic ResetA2 +12V +12 VDCA3 TMS Test Mde SelectA4 TDI Test Data InputA5 +5V +5 VDCA6 INTA Interrupt AA7 INTC Interrupt CA8 +5V +5 VDCA9 RESV01 Reserved VDCA10 +5V +3.3V Signal Rail +V I/O (+5 V or +3.3 V)A11 RESV03 Reserved VDCA12 GND03 (OPEN) (OPEN) Ground or Open (Key)A13 GND05 (OPEN) (OPEN) Ground or Open (Key)A14 RESV05 Reserved VDCA15 RESET ResetA16 +5V +3.3V Signal Rail +V I/O (+5 V or +3.3 V)A17 GNT Grant PCI useA18 GND08 GroundA19 RESV06 Reserved VDCA20 AD30 Address/Data 30A21 +3.3V01 +3.3 VDCA22 AD28 Address/Data 28A23 AD26 Address/Data 26A24 GND10 GroundA25 AD24 Address/Data 24A26 IDSEL Initialization Device SelectA27 +3.3V03 +3.3 VDCA28 AD22 Address/Data 22A29 AD20 Address/Data 20A30 GND12 GroundA31 AD18 Address/Data 18A32 AD16 Address/Data 16A33 +3.3V05 +3.3 VDCA34 FRAME Address or Data phaseA35 GND14 GroundA36 TRDY Target ReadyA37 GND15 GroundA38 STOP Stop Transfer CycleA39 +3.3V07 +3.3 VDCA40 SDONE Snoop DoneA41 SBO Snoop BackoffA42 GND17 GroundA43 PAR ParityA44 AD15 Address/Data 15A45 +3.3V10 +3.3 VDCA46 AD13 Address/Data 13A47 AD11 Address/Data 11A48 GND19 GroundA49 AD9 Address/Data 9A52 C/BE0 Command, Byte Enable 0A53 +3.3V11 +3.3 VDCA54 AD6 Address/Data 6A55 AD4 Address/Data 4A56 GND21 GroundA57 AD2 Address/Data 2A58 AD0 Address/Data 0A59 +5V +3.3V Signal Rail +V I/O (+5 V or +3.3 V)A60 REQ64 Request 64 bit ?A61 VCC11 +5 VDCA62 VCC13 +5 VDC A63 GND GroundA64 C/BE7# Command, Byte Enable 7A65 C/BE5# Command, Byte Enable 5A66 +5V +3.3V Signal Rail +V I/O (+5 V or +3.3 V)A67 PAR64 Parity 64 ?A68 AD62 Address/Data 62A69 GND GroundA70 AD60 Address/Data 60A71 AD58 Address/Data 58A72 GND GroundA73 AD56 Address/Data 56A74 AD54 Address/Data 54A75 +5V +3.3V Signal Rail +V I/O (+5 V or +3.3 V)A76 AD52 Address/Data 52A77 AD50 Address/Data 50A78 GND GroundA79 AD48 Address/Data 48A80 AD46 Address/Data 46A81 GND GroundA82 AD44 Address/Data 44A83 AD42 Address/Data 42A84 +5V +3.3V Signal Rail +V I/O (+5 V or +3.3 V)A85 AD40 Address/Data 40A86 AD38 Address/Data 38A87 GND GroundA88 AD36 Address/Data 36A89 AD34 Address/Data 34A90 GND GroundA91 AD32 Address/Data 32A92 RES ReservedA93 GND GroundA94 RES Reserved B1 -12V -12 VDCB2 TCK Test ClockB3 GND GroundB4 TDO Test Data OutputB5 +5V +5 VDCB6 +5V +5 VDCB7 INTB Interrupt BB8 INTD Interrupt DB9 PRSNT1 ReservedB10 RES +V I/O (+5 V or +3.3 V)B11 PRSNT2 ?B12 GND (OPEN) (OPEN) Ground or Open (Key)B13 GND (OPEN) (OPEN) Ground or Open (Key)B14 RES Reserved VDCB15 GND ResetB16 CLK ClockB17 GND GroundB18 REQ RequestB19 +5V +3.3V Signal Rail +V I/O (+5 V or +3.3 V)B20 AD31 Address/Data 31B21 AD29 Address/Data 29B22 GND GroundB23 AD27 Address/Data 27B24 AD25 Address/Data 25B25 +3.3V +3.3VDCB26 C/BE3 Command, Byte Enable 3B27 AD23 Address/Data 23B28 GND GroundB29 AD21 Address/Data 21B30 AD19 Address/Data 19B31 +3.3V +3.3 VDCB32 AD17 Address/Data 17B33 C/BE2 Command, Byte Enable 2B34 GND13 GroundB35 IRDY Initiator ReadyB36 +3.3V06 +3.3 VDCB37 DEVSEL Device SelectB38 GND16 GroundB39 LOCK Lock busB40 PERR Parity ErrorB41 +3.3V08 +3.3 VDCB42 SERR System ErrorB43 +3.3V09 +3.3 VDCB44 C/BE1 Command, Byte Enable 1B45 AD14 Address/Data 14B46 GND18 GroundB47 AD12 Address/Data 12B48 AD10 Address/Data 10B49 GND20 GroundB50 (OPEN) GND (OPEN) Ground or Open (Key)B51 (OPEN) GND (OPEN) Ground or Open (Key)B52 AD8 Address/Data 8B53 AD7 Address/Data 7B54 +3.3V12 +3.3 VDCB55 AD5 Address/Data 5B56 AD3 Address/Data 3B57 GND22 GroundB58 AD1 Address/Data 1B59 VCC08 +5 VDCB60 ACK64 Acknowledge 64 bit ?B61 VCC10 +5 VDCB62 VCC12 +5 VDC B63 RES ReservedB64 GND GroundB65 C/BE6# Command, Byte Enable 6B66 C/BE4# Command, Byte Enable 4B67 GND GroundB68 AD63 Address/Data 63B69 AD61 Address/Data 61B70 +5V +3.3V Signal Rail +V I/O (+5 V or +3.3 V)B71 AD59 Address/Data 59B72 AD57 Address/Data 57B73 GND GroundB74 AD55 Address/Data 55B75 AD53 Address/Data 53B76 GND GroundB77 AD51 Address/Data 51B78 AD49 Address/Data 49B79 +5V +3.3V Signal Rail +V I/O (+5 V or +3.3 V)B80 AD47 Address/Data 47B81 AD45 Address/Data 45B82 GND GroundB83 AD43 Address/Data 43B84 AD4
