Microcontroller Volumes thiab nqi

Mar 08, 2019

Hauv xyoo 2002, txog li 55% ntawm tag nrho CPUs muag hauv ntiaj teb no muaj 8-microcontrollers thiab microprocessors. [10]


Ntau tshaj li ob npaug ntawm 8-microcontrollers tau muag hauv 1997, [11] thiab raws li Semico, muaj tshaj li plaub plhom 8-ntsis microcontrollers tau muag hauv xyoo 2006. [12] Tsis ntev los no, Semico tau thov MCU lag luam loj hlob 36.5% hauv xyoo 2010 thiab 12% hauv 2011. [13]


Ib lub tsev nyob hauv ib lub teb chaws uas tsim tau tsuas yog muaj plaub hom microprocessors nkaus xwb, tab sis ze peb lub chaw ua ke ntawm microcontrollers. Lub tsheb nruab nrab ntawm lub tsheb muaj txog 30 microcontrollers. Lawv tuaj yeem pom muaj nyob rau hauv ntau lub xov tooj hluav taws xob xws li cov cav tov ntxhua khaub ncaws, microwave ncu, thiab xov tooj.


Teeb pom kev, 8-ntsis ntu tau dominated MCU lag luam [..] 16-microcontrollers los ua cov coob ntim MCU qeb hauv 2011, overtaking 8-ntsis li thawj zaug xyoo ntawd [..] IC Insights ntseeg tau tias cov pleev ntawm MCU tom khw yuav muaj kev hloov ntau yam hauv tsib xyoos tom ntej nrog rau 32-ntsis liaj teb ua kom muaj kev sib koom ua ke ntawm cov khoom muag thiab qhov ntau ntau. Los ntawm 2017, 32-ntsis MCUs yuav tsum nco txog 55% ntawm microcontroller muag [..] Raws li qhov ntsuas, 32-ntsis MCUs yuav tsum muaj nyiaj 38% ntawm microcontroller tuaj rau xyoo 2017, thaum 16-ntsis cov khoom siv 34% ntawm tag nrho, thiab 4- / 8-ntsis designs yog kwv yees li 28% ntawm units muag xyoo ntawd. 32-ntsis MCU kev lag luam yuav tsum muaj kev loj hlob sai vim yog pheej xav thov kom muaj ntau dua qhov muaj tseeb ntawm cov txheej txheem tsim thiab qhov loj hlob hauv kev siv Internet. [..] Hauv ob peb xyoos tom ntej no, txoj haujlwm 32-ntsis MCUs yuav tsum paub txog 25% ntawm kev ua haujlwm hauv tsheb.

Tus nqi tsim khoom siv yuav yog $ 0.10 rau ib chav tsev.


Tus nqi tau plummeted dhau lub sijhawm, nrog rau qhov pheej yig tshaj 8-ntsis microcontrollers uas muaj nyob rau hauv 0.03 USD hauv 2018 [15], thiab qee qhov 32-ntsis microcontrollers ncig Teb Chaws Asmeskas $ 1 rau cov zoo sib xws.


Nyob rau hauv 2012, tom qab lub ntiaj teb muaj kev puas tsuaj - qhov phem tshaj plaws qhov kev muag khoom poob txhua xyoo thiab qhov rov qab thiab qhov muag nruab nrab ntawm xyoo-tshaj-plawg 17% -yog qhov txo tsawg txij thaum 1980s-qhov nqi nruab nrab ntawm lub microcontroller yog US $ 0.88 ($ 0.69 rau 4- / 8-ntsis, $ 0.59 rau 16-ntsis, $ 1.76 rau 32-ntsis). [14]


Nyob rau hauv 2012, thoob ntiaj teb kev muag khoom ntawm 8-ntsis microcontrollers tau nyob ib ncig ntawm $ 4 billion, thaum 4-ntsis microcontrollers kuj pom qhov muag loj. [16]


Nyob rau 2015, 8-ntsis microcontrollers yuav raug them $ 0.311 (1,000 units), [17] 16-ntsis rau $ 0.385 (1,000 units), [18] thiab 32-ntsis rau $ 0.378 (1,000 units, tab sis tom $ 0.35 rau 5,000). [19]


Hauv xyoo 2018, 8-ntsis microcontrollers tuaj yeem them tau rau $ 0.03 [15], 16-ntsis rau $ 0.393 (1,000 units, tab sis tom $ 0.563 rau $ 100 lossis $ 0.349 rau tag nrho cov lus ntawm 2,000), [20] thiab 32-ntsis rau $ 0.503 (1,000 chav nyob, tab sis tom $ 0.466 rau 5,000). [21] Tus nqi qis dua 32-ntsis microcontroller, hauv ib chav ntawm ib qho, yuav tsum muaj rau $ 0.891. [22]


Nyob rau hauv 2018, tus nqi qis dua microcontrollers saum toj no los ntawm 2015 yog txhua yam kim tshaj (nrog rau kev nce nqi ntawm xyoo 2018 thiab 2015 tus nqi rau cov koog no): 8-ntsis microcontroller tau them rau $ 0.319 (1,000 units) los yog 2.6% [23] 16-nqe ib zaug rau $ 0.464 (1,000 units) lossis 21% siab dua, [24] thiab 32-ntsis ib tug $ 0.503 (1,000 units, tab sis tom $ 0.466 rau 5,000) lossis 33% siab dua.
