Muaj pes tsawg daim chips nyob hauv ib lub tsheb?

Muaj pes tsawg daim chips nyob hauv ib lub tsheb?Los yog, muaj pes tsawg daim chips xav tau lub tsheb?

Honestly, nws nyuaj rau teb.Vim nws nyob ntawm tus tsim ntawm lub tsheb nws tus kheej.Txhua lub tsheb xav tau cov chips sib txawv, tsawg li kaum rau ntau pua, ntau li ntau txhiab lossis ntau txhiab daim chips.Nrog rau txoj kev loj hlob ntawm automotive txawj ntse, hom chips kuj tau nce los ntawm 40 mus rau ntau tshaj 150.

Automotive chips, zoo li tib neeg lub hlwb, tuaj yeem muab faib ua tsib pawg los ntawm kev ua haujlwm: xam, kev xaav, kev ua tiav, kev sib txuas lus, kev cia khoom thiab kev siv hluav taws xob.

Ntxiv subdivision, tuaj yeem muab faib ua cov nti tswj, suav nti, ntsuas nti, kev sib txuas lus nti,nco chip, kev ruaj ntseg nti, hwj chim nti,tsav nti, hwj chim tswj nti cuaj pawg.

Automotive nti cuaj pawg:

1. Tswj nti:MCU, SOC

Thawj kauj ruam kom nkag siab txog automotive electronics yog kom nkag siab txog kev tswj hluav taws xob.Lub ECU tuaj yeem hais tau tias yog lub khoos phis tawj sib txuas uas tswj hwm lub tshuab loj ntawm lub tsheb.Ntawm lawv, on-board MCU tuaj yeem hu ua lub hlwb ntawm lub tsheb ECU, uas yog lub luag haujlwm rau kev suav thiab ua cov ntaub ntawv ntau yam.

Feem ntau, ECU hauv lub tsheb yog lub luag haujlwm rau kev ua haujlwm sib cais, nruab nrog MCU, raws li Deppon Securities.Tej zaum kuj yuav muaj cov xwm txheej uas ib qho ECU tau nruab nrog ob lub MCUS.

MCUS suav txog li 30% ntawm tus naj npawb ntawm cov khoom siv semiconductor siv hauv lub tsheb, thiab tsawg kawg yog 70 yuav tsum tau rau ib lub tsheb tnws saum MCU nti.

2. xam nti: CPU, GPU

CPU feem ntau yog lub chaw tswj hwm ntawm SoC nti.Nws qhov txiaj ntsig yog nyob rau hauv kev teem sijhawm, kev tswj hwm thiab kev sib koom tes muaj peev xwm.Txawm li cas los xij, CPU muaj tsawg dua cov khoos phis tawj thiab tsis tuaj yeem ua tau raws li tus lej loj ntawm cov haujlwm yooj yim sib txuas.Yog li ntawd, kev tsav tsheb tsav SoC feem ntau xav tau kev sib koom ua ke ib lossis ntau Xpus ntxiv rau CPU kom ua tiav AI suav.

3. Lub zog nti: IGBT, silicon carbide, lub zog MOSFET

Lub zog semiconductor yog lub hauv paus ntawm kev hloov hluav taws xob hluav taws xob thiab kev tswj xyuas hluav taws xob hauv cov khoom siv hluav taws xob, uas yog siv los hloov qhov voltage thiab zaus hauv cov khoom siv hluav taws xob, DC thiab AC hloov dua siab tshiab.

Siv lub zog MOSFET ua piv txwv, raws li cov ntaub ntawv, nyob rau hauv cov tsoos roj tsheb, qhov tsawg-voltage MOSFET ib lub tsheb yog hais txog 100. Nyob rau hauv lub zog tshiab tsheb, qhov nruab nrab noj nruab nrab thiab high voltage MOSFET ib lub tsheb tau nce mus rau ntau. tshaj 200. Nyob rau hauv lub neej yav tom ntej, MOSFET kev siv ib lub tsheb nyob rau hauv nruab nrab thiab high-end qauv yuav tsum nce mus rau 400.

4. Kev sib txuas lus nti: cellular, WLAN, LIN, direct V2X, UWB, CAN, satellite positioning, NFC, Bluetooth, ETC, Ethernet thiab hais txog;

Kev sib txuas lus nti tuaj yeem muab faib ua kev sib txuas lus thiab kev sib txuas lus wireless.

Wired kev sib txuas lus yog tsuas yog siv rau ntau yam ntaub ntawv kis tau tus mob ntawm cov khoom nyob rau hauv lub tsheb.

Kev sib txuas lus wireless tuaj yeem paub txog kev sib txuas ntawm lub tsheb thiab tsheb, tsheb thiab tib neeg, tsheb thiab khoom siv, tsheb thiab ib puag ncig ib puag ncig.

Ntawm lawv, tus naj npawb ntawm cov transceivers tuaj yeem loj, raws li cov ntaub ntawv kev lag luam, qhov nruab nrab CAN / LIN transceiver daim ntawv thov ntawm lub tsheb yog tsawg kawg yog 70-80, thiab qee lub tsheb ua haujlwm tuaj yeem ncav cuag ntau dua 100, lossis ntau dua 200.

5. Nco nti: DRAM, NOR FLASH, EEPROM, SRAM, NAND FLASH

Lub cim xeeb nti ntawm lub tsheb yog siv los khaws ntau yam kev pab cuam thiab cov ntaub ntawv ntawm lub tsheb.

Raws li kev txiav txim siab ntawm lub tuam txhab semiconductor hauv Kaus Lim Qab Teb ntawm qhov kev thov rau DRAM rau kev tsav tsheb ntse, lub tsheb tau kwv yees tias muaj qhov xav tau siab tshaj plaws rau DRAM / NAND Flash mus txog 151GB / 2TB, raws li, thiab cov chav kawm thiab ADAS autonomous kev tsav tsheb muaj kev siv ntau tshaj plaws ntawm kev nco chips.

6. Fais fab / Analog nti: SBC, analog pem hauv ntej kawg, DC / DC, digital cais, DC / AC

Analog nti yog tus choj txuas rau lub ntiaj teb tiag tiag thiab lub ntiaj teb digital, feem ntau yog hais txog cov analog circuits uas muaj qhov tsis kam, capacitor, transistor, thiab lwm yam. .) integrated circuit.

Raws li Oppenheimer txheeb cais, analog circuits account rau 29% ntawm tsheb chips, ntawm uas 53% yog cov teeb liab saw cores thiab 47% yog lub hwj chim tswj chips.

7. Tsav tsheb nti: siab sab tsav tsheb, qis sab tsav tsheb, LED / zaub, qhov rooj tsav tsheb, choj, lwm yam tsav tsheb, thiab lwm yam

Nyob rau hauv automotive electronic system, muaj ob txoj hauv kev los tsav lub load: qis sab tsav thiab sab tsav siab.

High-side drives feem ntau yog siv rau lub rooj zaum, teeb pom kev zoo, thiab kiv cua.

Tsawg sab tsav yog siv rau lub cev muaj zog, cua sov, thiab lwm yam.

Ua ib lub tsheb tswj hwm hauv Tebchaws Meskas ua piv txwv, tsuas yog lub hauv ntej lub cev tswj hwm thaj tsam tau teeb tsa nrog 21 tus tsav tsheb siab, thiab lub tsheb siv ntau dua 35.

8. Sensor nti: ultrasonic, duab, suab, laser, inertial navigation, millimeter yoj, ntiv tes, infrared, voltage, kub, tam sim no, av noo, txoj hauj lwm, siab.

Automotive sensors yuav muab faib ua lub cev sensors thiab ib puag ncig sensing sensors.

Hauv kev ua haujlwm ntawm lub tsheb, lub tsheb sensor tuaj yeem sau lub cev lub xeev (xws li qhov kub thiab txias, siab, txoj haujlwm, ceev, thiab lwm yam) thiab cov ntaub ntawv ib puag ncig, thiab hloov cov ntaub ntawv khaws cia rau hauv cov teeb liab hluav taws xob rau kev xa mus rau lub hauv paus tswj chav tsev. tsheb.

Raws li cov ntaub ntawv, lub tsheb ntse tsav theem 2 yuav tsum nqa rau 6 sensors, thiab L5 lub tsheb yuav tsum nqa 32 sensors.

9. Kev ruaj ntseg nti: T-Box/V2X kev ruaj ntseg nti, eSIM/eSAM kev ruaj ntseg nti

Automotive kev ruaj ntseg nti yog ib hom kev sib koom ua ke nrog kev sib koom ua ke cryptographic algorithm thiab lub cev tiv thaiv kev tawm tsam.

Niaj hnub no, nrog rau kev loj hlob ntawm cov tsheb ntse, cov khoom siv hluav taws xob hauv lub tsheb yuav inevitably nce, thiab nws yog tsav los ntawm kev loj hlob ntawm cov chips.

Raws li cov ntaub ntawv muab los ntawm Tuam Tshoj Association of Automobile Manufacturers, lub tsheb chips yuav tsum tau rau cov tsoos roj tsheb yog 600-700, tus naj npawb ntawm cov tsheb chips xav tau rau hluav taws xob tsheb yuav nce mus rau 1600 / tsheb, thiab qhov kev thov rau chips rau ntau lub tsheb txawj ntse yuav tsum nce mus rau 3000 / tsheb.

Nws tuaj yeem hais tias lub tsheb niaj hnub zoo li lub khoos phis tawj loj ntawm wheels.
