E mōhio ana koe he aha te mahi a te IC LED?

Ko te Arahiko Whakakotahi o ngā Diode Whakaputa Marama e kiia ana ko te IC LED. He momo arahiko whakauru i hangaia mō te whakahaere me te taraiwa i ngā LED, ngā diode whakaputa-marama rānei. He maha ngā mahi a ngā arahiko whakauru LED (IC), tae atu ki te whakahaere ngaohiko, te whakaiti i te kanapa, me te whakahaere iahiko, e āwhina ana i te whakahaere tika me te whai hua o ngā pūnaha rama LED. Ko ngā tono mō ēnei arahiko whakauru (IC) ko ngā panui whakaaturanga, ngā rama, me te whakamārama waka.
Ko te kupu whakarāpopoto mō te Integrated Circuit ko IC. He taputapu hiko iti nei i hangaia mai i ngā wāhanga maha i hangaia ki te haurua-ira, tae atu ki ngā ātete, ngā transistors, ngā capacitors, me ētahi atu ara iahiko hiko. Ko ngā mahi hiko tae atu ki te whakanui, te whakawhiti, te whakahaere ngaohiko, te tukatuka tohu, me te rokiroki raraunga ngā mahi matua o tētahi ara iahiko whakauru (IC). He maha ngā hua hiko, pērā i ngā rorohiko, ngā waea pūkoro, ngā pouaka whakaata, ngā taputapu hauora, ngā pūnaha motuka, me ētahi atu, e whakamahi ana i ngā ara iahiko whakauru (IC). Mā te whakakotahi i ētahi wāhanga ki roto i te maramara kotahi, ka taea e rātou te whakaiti i ngā taputapu hiko, te mahi pai ake, me te whakamahi i te iti o te mana. Ko te nuinga o ngā pūnaha hiko e whakamahi ana i ngā IC hei wāhanga hanga matua, e huri haere ana i te rāngai hiko.

He maha ngā momo IC, ia IC he mea hanga mō tētahi whakamahinga me tētahi kaupapa motuhake. Anei ētahi momo IC rongonui:

MCU: Kei roto i ēnei porowhita whakauru he matua tukatuka iti, he mahara, me ngā taputapu tāpiri katoa i runga i te maramara kotahi. Ka hoatu e rātou he mātauranga me te mana whakahaere ki ngā taputapu, ā, ka whakamahia i roto i ngā momo pūnaha whakauru.

Ka whakamahia e ngā rorohiko me ētahi atu pūnaha uaua ngā tukatuka iti (MPU) hei waeine tukatuka matua (CPU). Ka whakahaerehia e rātou ngā tataunga me ngā tohutohu mō ngā momo mahi.

He mea hanga motuhake ngā IC DSP mō te tukatuka i ngā tohu matihiko, pērā i ngā awa oro me ngā ataata. He maha ngā whakamahinga o ēnei i roto i ngā tono pērā i te tukatuka whakaahua, ngā taputapu oro, me ngā whakawhitiwhiti kōrero.
Ngā Porowhita Whakauru Motuhake mō te Taupānga (ASIC): He porowhita whakauru motuhake ngā ASIC, ā, he mea hanga mō ētahi whakamahinga, mō ētahi kaupapa rānei. Ka whakaratohia e rātou te mahi tino pai mō tētahi kaupapa motuhake, ā, he maha ngā wā ka kitea i roto i ngā taputapu motuhake pērā i ngā pūnaha whatunga me ngā taputapu hauora.

Ko ngā Ara Kūaha Ka taea te Whakahōtaka i te Mara, arā, ko ngā FPGA, he ara iahiko whakauru ka taea te whakarite kia taea te whakahaere i ngā mahi motuhake i muri i te hanganga. He ngāwari ki te urutau, ā, he maha ngā kōwhiringa whakahou hōtaka.

Ngā ara iahiko whakauru anaro (IC): Ka tukatukahia e ēnei taputapu ngā tohu tonu, ā, ka whakamahia i roto i ngā tono whakahaere ngaohiko, whakanui, me te tātari. Ko ngā kaiwhakahaere ngaohiko, ngā whakanui oro, me ngā whakanui whakahaere (op-amp) ētahi tauira.
Ka taea e ngā IC whai mahara te penapena me te tiki raraunga. Ko ētahi tauira ko te Mahara Pānui-Anake Ka Taea te Mukua e te Hiko (EEPROM), te Mahara Irahiko, te Mahara Uru Matapōkere Tuturu (SRAM), me te Mahara Uru Matapōkere Hihiri (DRAM).

Ngā IC e whakamahia ana i roto i te whakahaere hiko: Ka whakahaerehia e ēnei IC te hiko e whakamahia ana i roto i ngā taputapu hiko. Ko te whakahaere i te tuku hiko, te utu pākahiko, me te hurihanga ngaohiko ētahi o ngā mahi e whakamahia ai.

Mā ēnei ara iahiko whakauru (IC) ka taea te hono i waenga i ngā rohe anarohiko me ngā rohe matihiko mā te huri i ngā tohu anarohiko ki te matihiko, me te hurihanga. E mōhiotia ana ēnei ko ngā kaitahuri anarohiko-ki-matihiko (ADC) me ngā kaitahuri matihiko-ki-anarohiko (DAC).

He torutoru noa iho ēnei whakarōpūtanga, ā, he whānui te mara o ngā ara iahiko whakauru (IC), ā, kei te tipu haere tonu i te puta mai o ngā tono hou me ngā putanga hangarau hou.
