- Microchip imakhulupirira kuti banja lake lazinthu ndi limodzi la mabanja otetezeka kwambiri amtundu wake pamsika lerolino, zikagwiritsidwa ntchito m'njira yofunira komanso pansi pamikhalidwe yabwinobwino.
- Pali njira zosakhulupirika komanso zosaloledwa zomwe zimagwiritsidwa ntchito kuphwanya chitetezo cha code. Njira zonsezi, monga momwe tikudziwira, zimafuna kugwiritsa ntchito zinthu za Microchip m'njira yosiyana ndi zomwe zili mu Microchip's Data Sheets. N’kutheka kuti munthu amene amachita zimenezi ndi wakuba zinthu zanzeru.
- Microchip ndi wokonzeka kugwira ntchito ndi kasitomala amene akukhudzidwa ndi kukhulupirika kwa code yawo.
- Ngakhale Microchip kapena wopanga semiconductor wina aliyense sangatsimikizire chitetezo cha code yawo. Kutetezedwa kwa ma code sikutanthauza kuti tikutsimikizira kuti chinthucho ndi "chosasweka."
Chitetezo cha code chikusintha nthawi zonse. Ife ku Microchip ndife odzipereka kupitiliza kukonza zida zotetezedwa ndi zinthu zathu. Kuyesa kuphwanya chitetezo cha code ya Microchip kungakhale kuphwanya Digital Millennium Copyright Act. Ngati izi zikuloleza kulowa kwa pulogalamu yanu kapena ntchito zina zomwe zili ndi copyright, mungakhale ndi ufulu woyimba mlandu malinga ndi lamuloli. Zambiri zomwe zili m'bukuli zokhudzana ndi chipangizocho.
Zizindikiro
mapulogalamu ndi zina zotere zimaperekedwa kuti zitheke Dzina la Microchip ndi logo, logo ya Microchip, dsPIC, ndipo zitha kulowedwa m'malo ndi zosintha. Ndi udindo wanu FlashFlex, flexPWR, JukeBlox, KEELOQ, KEELOQ logo, Kleer, onetsetsani kuti pulogalamu yanu ikugwirizana ndi zomwe mukufuna. LANCheck, MediaLB, ZAMBIRI, logo YABWINO, MPLAB, MICROCHIP SIIKUYAMBIRA KAPENA OptoLyzer, PIC, PICSTART, logo ya PIC32, RightTouch, SpyNIC, ZINSINSI ZAmtundu ULIWONSE KAYA EXPRESS KAPENA SST, SST Logo, IMPI/SuperFlash, ndi zolembetsedwa. ZOLEMBEDWA KAPENA M'MWAWA, MALAMULO KAPENA zizindikiro za Microchip Technology Incorporated mu M'MAYIKO, ZOKHUDZANA NDI CHIdziwitso, USA ndi mayiko ena. KUPHATIKIRA KOMA OSATI ZOKHALA NDI MKHALIDWE WAKE, UKHALIDWE, KACHIWIRI, NTCHITO KAPENA The Embedded Control Solutions Company ndi mTouch NDIKUBWERA PA CHOLINGA.
Microchip imakana zidziwitso zonse zolembetsedwa za Microchip Technology Incorporated zobwera chifukwa cha chidziwitsochi ndikugwiritsa ntchito kwake. Kugwiritsa ntchito zida za Microchip ku USA pakuthandizira moyo ndi/kapena chitetezo kumagwiritsidwa ntchito pa Analog-for-the-Digital Age, BodyCom, chipKIT, chipKIT logo, chiopsezo cha wogula, ndipo wogula amavomereza kuteteza, kubwezera ndi CodeGuard, dsPICDEM. . Palibe ziphaso zomwe zili ndi logo ya KleerNet, MiWi, MPASM, MPF, logo Yotsimikizika ya MPLAB, yoperekedwa, mosabisa kapena ayi, pansi pa Microchip MPLIB, MPLINK, MultiTRAK, NetDetach, Omniscient Code
ufulu wazinthu zanzeru. Generation, PICDEM, PICDEM.net, PICkit, PICtail, RightTouch logo, REAL ICE, SQI, Serial Quad I/O, TotalEndurance, TSHARC, USBCheck, VariSense, ViewSpanya,
WiperLock, Wireless DNA, ndi ZENA ndi zizindikiro za Microchip Technology Incorporated ku USA ndi mayiko ena. SQTP ndi chizindikiro cha ntchito cha Microchip Technology Incorporated
ku USA Silicon Storage Technology ndi chizindikiro cholembetsedwa cha Microchip Technology Inc. m'maiko ena. GestIC ndi zizindikiro zolembetsedwa za Microchip Technology Germany II GmbH & Co. KG, kampani ya Microchip Technology Inc., m'maiko ena. Zizindikiro zina zonse zotchulidwa pano ndi zamakampani awo.
