Txhawm rau ua tiav kev lag luam txhim khu kev qha ntawm 200 degree, kev cia siab ib leeg ntawm kev tshuaj xyuas siv cov txheej txheem semiconductor tsis txaus. Hloov chaw, kev sib koom tes daws teeb meem thoob plaws plaub theem- cov khoom siv, cov khoom siv, kev tsim hluav taws xob, thiab kev ua haujlwm tsis zoo- yog yuav tsum tau. Lub siab -kub tsis kam ntawm lubZT6206H siab -kub ARM processoryog tsim los ntawm cov thev naus laus zis hauv qab no:
Ua ntej, siab -kub SOI (Silicon- ntawm-Insulator) thev naus laus zis lossis tshwj xeeb uas siv cov tshuab silicon tshwj xeeb yog siv rau wafer fabrication txhawm rau txhawm rau PN junction leakage tam sim no thiab latch- nce cov teebmeem. Rau Cortex-M4 core, static to tam sim no ntawm 200℃tej zaum yuav yog ob qhov kev txiav txim siab ntau dua li ntawm 25 degree. ZT6206H tswj siab - qhov kub thiab txias ntawm lub zog siv hluav taws xob nyob rau hauv qhov kev siv tau los ntawm kev ua kom muaj qhov ntsuas hluav taws xob thiab ua kom zoo rau kev sib cuag zoo. Thib ob, CQFP (Ceramic Quad Flat Package) raug xaiv rau kev ntim khoom, uas nws cov coefficient ntawm thermal expansion (CTE) sib tw ntawm PCB ceramic substrates lossis hlau-cov core boards, tiv thaiv kev sib koom ua ke ntawm kev qaug zog thiab tawg los ntawm kev kub siab -kub cycling. Cov kab noj hniav ceramic kuj muab kev tiv thaiv hermetic tiv thaiv kev yaig ntawm cov nti sab hauv los ntawm siab -siab downhole noo noo thiab hydrogen sulfide gas.
Nyob rau hauv cov nqe lus ntawm kev cia siab rau ua hauj lwm, lub processor nta ib tug meej kub-segmented kev khiav hauj lwm hom.
puv-Kev ua haujlwm ntau (tsawg dua lossis sib npaug li 175 degree):Lub ntsiab zaus ntawm 80 MHz, nrog rau txhua qhov peripherals (xws li PLL, RTC, I²C, CAN) ua haujlwm ib txwm.
Derated ntau yam (175℃txog 200 degree):Cov zaus tseem ceeb txo mus rau 16 MHz, nrog qee qhov analog thiab moos - cuam tshuam cov khoom siv (PLL, RTC, I²C, CAN) tsis taus; Txawm li cas los xij, cov tub ntxhais, SRAM, flash nco, SPI, USART, ADC, DAC, kev ua haujlwm amplifiers, thiab cov sib piv tseem ua haujlwm.
Qhov kev tsim no ua rau lub kaw lus tswj hwm cov ntaub ntawv yooj yim tau txais thiab qis -kev sib txuas lus ceev ntawm qhov kub siab tshaj 200 degree, zam kev kaw tag nrho. Txawm hais tias qhov ua tau - nyob rau hauv qhov kub thiab txias sensor muaj qhov nominal ntau txog 175 degree, nws ua hauj lwm raws li ib tug tshwm sim rau derated hom: thaum lub sensor nyeem ntawv nce mus txog 175 degree, lub kaw lus nquag hloov mus rau qis - zaus hom thiab kaw siab - hwj chim- siv peripherals.
Txhawm rau tiv taus qhov kev vibration loj heev (feem ntau tshaj 20 g RMS, zaus 5-2000 Hz), cov hlau lead suab thiab qhov dav ntawm ZT6206H CQFP pob yog optimized. Ua ke nrog underfill los yog pin reinforcement, nws resists mechanical stress. Cov neeg tsim qauv yuav tsum tsis txhob tso cov txheej txheem ze rau siab - cov khoom loj (piv txwv li, transformers) lossis cov chaw raug tshem tawm hauv PCB layout, thiab siv cov ceramic lossis hlau-cov tub ntxhais PCBs los txhim kho tag nrho cov rigidity.
Qingdao ZITN tau tsim cov kev sim thiab tshuaj ntsuam xyuas tshwj xeeb hauv thaj tsam ntawm ultra-siab-kub hluav taws xob. Txhua ZT6206H dhau los ua pov thawj ua haujlwm ntawm 175℃thiab 200 degree, nrog cov ntaub ntawv qhia txog kev taug qab tau muab rau cov tsis tseem ceeb xws li siab -kub flash nco cov ntaub ntawv khaws cia, siab -kub ADC offset, thiab oscillator zaus drift. Rau kev sau npe-thaum-drilling instrument designers, qhov no tshem tawm qhov xav tau los tsim cov khoom kim heev -kub ntsuas platforms rau tag nrho - parameter tshuaj ntsuam. Kev tsim qauv tuaj yeem ua ncaj qha raws li lub rooj derating hauv daim ntawv teev cov ntaub ntawv, ua kom luv luv ntawm txoj kev loj hlob.
Hauv kev siv tswv yim, kev ntsuas kev ntseeg tau hauv qab no raug pom zoo:
- Muab X7R los yog C0G ceramic capacitors ze rau lub processor fais fab pins, thiab account rau capacitance attenuation ntawm qhov kub thiab txias (X7R yuav poob tshaj 70% capacitance ntawm 200 degree; C0G los yog siab -kub tantalum capacitors raug pom zoo hloov).
- Ntxiv qhov sib txawv lossis tam sim no - lub voj tsav tsheb mus rau USART thiab SPI cov kab sib txuas lus kom tiv taus siab - qhov kub thiab txias.
- Ua haujlwm ib ntus thiab ua haujlwm rov qab los ntawm cov ntaub ntawv tseem ceeb hauv SRAM, thiab kho ib qho - me ntsis yuam kev siv lub cim xeeb flash ECC (yog tias muaj).
Los ntawm kev sib txuas cov txheej txheem no nrog rau qhov siab tshaj -kub tsim ntawm ZT6206H, ib qho kev txhim khu kev qha ua tau raws li qhov yuav tsum tau ua ntawm downhole kev khiav hauj lwm.
