  • FET430PIF自制資料

    The MSP-FET430PIF is a Parallel Port interface (does not include target board) that is used to program and debug MSP430 FET tools and test boards through the JTAG interface. This interface is included in our FET tools, but sold without the development board. This interface uses a Parallel PC Port to communicate to the Debugger Software (IAR Kickstart software included) running on the PC. The interface uses the standard 14 pin header to communicate to the MSP430 device using the standard JTAG protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is extremely low power, no external power supply is required. The tool has an integrated software environment and connects directly to the PC which greatly simplifies the set-up and use of the tool. The flash development tool supports development with all MSP430 flash parts. Features MSP430 debugging interface to connect a MSP430-Flash-device to a Parallel port on a PC Supports JTAG debug protocol (NO support for Spy-Bi-Wire (2-wire JTAG) debug protocol, Spy-Bi-Wire (2-wire JTAG) is supported by MSP-FET430UIF) Parallel Port cable and a 14-conductor target cable Full documentation on CD ROM Integrated IAR Kickstart user interface which includes: Assembler Linker Limulator Source-level debugger Limited C-compiler Technical specifications: Backwardly compatable with existing FET tool boards.

  • MSP430 USB JTAG自制資料

    The MSP-FET430U14 is a powerful flash emulation tool to quickly begin application development on the MSP430 MCU. It includes USB debugging interface used to program and debug the MSP430 in-system through the JTAG interface or the pin saving Spy Bi-Wire (2-wire JTAG) protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is ultra-low power, no external power supply is required. The debugging tool interfaces the MSP430 to the included integrated software environment and includes code to start your design immediately.  The MSP-FET430UIF development tools supports development with all MSP430 flash devices

  • Agilent Wedge for Probing High

    IntroductionAs chip designers pack more functions into ICs,pin counts continue to grow and the space betweenpins keeps shrinking. Pin spacings of 0.5 mm and0.65 mm are not at all uncommon. The power ofthese new ICs is wonderful, to be sure, but trou-bleshooting them can be a chore because connect-ing scopes and logic analyzers has become muchmore difficult and less dependable.

  • 關于PCB封裝的資料收集整理.pdf

    關于PCB封裝的資料收集整理. 大的來說,元件有插裝和貼裝.零件封裝是指實際零件焊接到電路板時所指示的外觀和焊點的位置。是純粹的空間概念.因此不同的元件可共用同一零件封裝,同種元件也可有不同的零件封裝。像電阻,有傳統的針插式,這種元件體積較大,電路板必須鉆孔才能安置元件,完成鉆孔后,插入元件,再過錫爐或噴錫(也可手焊),成本較高,較新的設計都是采用體積小的表面貼片式元件(SMD)這種元件不必鉆孔,用鋼膜將半熔狀錫膏倒入電路板,再把SMD 元件放上,即可焊接在電路板上了。晶體管是我們常用的的元件之一,在DEVICE。LIB庫中,簡簡單單的只有NPN與PNP之分,但實際上,如果它是NPN的2N3055那它有可能是鐵殼子的TO—3,如果它是NPN的2N3054,則有可能是鐵殼的TO-66或TO-5,而學用的CS9013,有TO-92A,TO-92B,還有TO-5,TO-46,TO-52等等,千變萬化。還有一個就是電阻,在DEVICE 庫中,它也是簡單地把它們稱為RES1 和RES2,不管它是100Ω 還是470KΩ都一樣,對電路板而言,它與歐姆數根本不相關,完全是按該電阻的功率數來決定的我們選用的1/4W 和甚至1/2W 的電阻,都可以用AXIAL0.3 元件封裝,而功率數大一點的話,可用AXIAL0.4,AXIAL0.5等等。現將常用的元件封裝整理如下:電阻類及無極性雙端元件:AXIAL0.3-AXIAL1.0無極性電容:RAD0.1-RAD0.4有極性電容:RB.2/.4-RB.5/1.0二極管:DIODE0.4及DIODE0.7石英晶體振蕩器:XTAL1晶體管、FET、UJT:TO-xxx(TO-3,TO-5)可變電阻(POT1、POT2):VR1-VR5這些常用的元件封裝,大家最好能把它背下來,這些元件封裝,大家可以把它拆分成兩部分來記如電阻AXIAL0.3 可拆成AXIAL 和0.3,AXIAL 翻譯成中文就是軸狀的,0.3 則是該電阻在印刷電路板上的焊盤間的距離也就是300mil(因為在電機領域里,是以英制單位為主的。同樣的,對于無極性的電容,RAD0.1-RAD0.4也是一樣;對有極性的電容如電解電容,其封裝為RB.2/.4,RB.3/.6 等,其中“.2”為焊盤間距,“.4”為電容圓筒的外徑。對于晶體管,那就直接看它的外形及功率,大功率的晶體管,就用TO—3,中功率的晶體管,如果是扁平的,就用TO-220,如果是金屬殼的,就用TO-66,小功率的晶體管,就用TO-5,TO-46,TO-92A等都可以,反正它的管腳也長,彎一下也可以。對于常用的集成IC電路,有DIPxx,就是雙列直插的元件封裝,DIP8就是雙排,每排有4個引腳,兩排間距離是300mil,焊盤間的距離是100mil。SIPxx 就是單排的封裝。等等。值得我們注意的是晶體管與可變電阻,它們的包裝才是最令人頭痛的,同樣的包裝,其管腳可不一定一樣。例如,對于TO-92B之類的包裝,通常是1 腳為E(發射極),而2 腳有可能是B 極(基極),也可能是C(集電極);同樣的,3腳有可能是C,也有可能是B,具體是那個,只有拿到了元件才能確定。因此,電路軟件不敢硬性定義焊盤名稱(管腳名稱),同樣的,場效應管,MOS 管也可以用跟晶體管一樣的封裝,它可以通用于三個引腳的元件。Q1-B,在PCB 里,加載這種網絡表的時候,就會找不到節點(對不上)。在可變電阻
