♠ LPC2468 Micro imwe-chip 16-bit / 32-bit;512 kB flash, Ethernet, CAN, ISP / IAP, USB 2.0 igikoresho / host / OTG, interineti yibuka hanze
NXP Semiconductor yateguye microcontroller ya LPC2468 hafi ya 16-bit / 32-bit ya ARM7TDMI-S CPU yibanze hamwe nigihe nyacyo cyo gukemura ibibazo birimo JTAG hamwe nibisobanuro byashyizwemo.LPC2468 ifite 512 kB ya-chip yihuta yihutakwibuka.
Iyi flash yibuka ikubiyemo ububiko bwihariye bwa 128-bit yagutse yububiko hamwe nubwubatsi bwihuta butuma CPU ikora amabwiriza akurikirana kuva flash yibuka kuri 72 MHz ya sisitemu ntarengwa.Ikiranga nikuboneka gusa kuri LPC2000 ARM microcontroller yumuryango wibicuruzwa.
LPC2468 irashobora gukora byombi 32-bit ARM hamwe na 16-bit ya Thumb amabwiriza.Inkunga kubice bibiri byigisha bivuze ko injeniyeri ashobora guhitamo guhitamo ibyifuzo byabohaba imikorere cyangwa ingano yubunini kurwego rwibisanzwe.Iyo intangiriro ikora amabwiriza muri leta ya Thumb irashobora kugabanya ingano ya code kurenza 30% hamwe nigihombo gito gusa mumikorere mugihe ikora amabwiriza muri leta ya ARM yerekana intangiriroimikorere.
LPC2468 microcontroller nibyiza kubikorwa byinshi byitumanaho.Harimo 10/100 Ethernet Media Access Controller (MAC), USB yuzuye yihuta Igikoresho / Host / OTG Igenzura hamwe na 4 kB ya RAM yanyuma, bineUARTs, imiyoboro ibiri yubugenzuzi (CAN), imiyoboro ya SPI, ibyambu bibiri bya Synchronous Serial (SSP), Imigaragarire itatu ya I2C, hamwe na I2S.Gushyigikira iki cyegeranyo cyitumanaho ryitumanaho ni ibintu bikurikiraibice;an-chip 4 MHz oscillator yimbere yimbere, 98 kB ya RAM yose igizwe na 64 kB ya SRAM yaho, 16 kB SRAM kuri Ethernet, 16 kB SRAM kubwintego rusange DMA, 2 kB ya bateri ikoreshwa na SRAM, hamwe na Memory yo hanzeUmugenzuzi (EMC).
Ibiranga bituma iki gikoresho gikwiranye ninzira yo gutumanaho hamwe na protocole ihindura.Kuzuza ibyiciro byinshi byitumanaho bigenzura, ubushobozi bwisaha butandukanye, nibiranga kwibuka biratandukanyeIbihe 32-bit, byatejwe imbere 10-biti ADC, 10-bit DAC, ibice bibiri bya PWM, ibyuma bine byo guhagarika hanze, hamwe numurongo wa GPIO wihuta 160.
LPC2468 ihuza 64 ya pin ya GPIO hamwe nibyuma bishingiye kuri Vector Interrupt Controller (VIC) bivuze ibiinyongeramusaruro zo hanze zirashobora kubyara impande zose.Ibi byose biranga bituma LPC2468 ibereye cyane kugenzura inganda na sisitemu yubuvuzi.
Processor ARM7TDMI-S itunganya, ikora kuri 72 MHz.
12 512 kB kuri chip flash yibuka yibikoresho hamwe na In-Sisitemu Porogaramu (ISP) hamwe nubushobozi bwa Porogaramu (IAP).Porogaramu yibikoresho ya Flash iri kuri bisi ya ARM kugirango ikore neza CPU.
98 kB kuri chip SRAM ikubiyemo:
64 kB ya SRAM kuri bisi ya ARM kugirango ikore neza CPU.
16 kB SRAM kuri interineti ya Ethernet.Irashobora kandi gukoreshwa nkintego rusange SRAM.
16 kB SRAM kubwintego rusange DMA ikoresha nayo igerwaho na USB.
Kubika 2 kB SRAM ububiko bwamakuru bukomoka kumurongo wigihe cyamasaha (RTC).
Sisitemu ebyiri ziteye imbere cyane Bus (AHB) sisitemu yemerera icyarimwe Ethernet DMA, USB DMA, hamwe na progaramu ya progaramu kuva kuri chip flash nta mpaka.
EMC itanga inkunga kubikoresho bidafite ububiko bwibikoresho nka RAM, ROM na flash, hamwe nibuka rifite imbaraga nkigipimo kimwe cya SDRAM.
Iterambere rya Vectored Interrupt Controller (VIC), ushyigikira interineti zigera kuri 32.
Purpose Intego rusange ya DMA mugenzuzi (GPDMA) kuri AHB ishobora gukoreshwa hamwe na SSP, I 2S-bus, na SD / MMC interineti kimwe no kwibuka-kwibuka.
Inter Imigaragarire ya Serial:
Ethernet MAC hamwe na interineti ya MII / RMII hamwe na DMA mugenzuzi.Iyi mikorere iba kuri AHB yigenga.
USB 2.0 yuzuye yihuta yicyuma cyibikoresho / host / OTG mugenzuzi hamwe na chip PHY hamwe na DMA mugenzuzi.
Bane UART hamwe nibice bya baud igipimo cyibisekuru, kimwe gifite modem igenzura I / O, imwe hamwe na IrDA, byose hamwe na FIFO.
URASHOBORA kugenzura imiyoboro ibiri.
Control Umugenzuzi wa SPI.
Control Abagenzuzi babiri ba SSP, hamwe na FIFO hamwe nubushobozi bwa protocole nyinshi.Imwe nimwe isimbuza icyambu cya SPI, igabana ihagarikwa ryayo.SSPs irashobora gukoreshwa hamwe na GPDMA mugenzuzi.
Inter Interineti eshatu za I2C-bus (imwe ifite imiyoboro ifunguye na kabiri ifite ibyuma bisanzwe byambu).
I 2S (Inter-IC Ijwi) Imigaragarire yo kwinjiza amajwi cyangwa ibisohoka.Irashobora gukoreshwa hamwe na GPDMA.
Abandi bo hanze:
Interface Ikarita yububiko bwa SD / MMC.
160 Intego rusange I / O pin hamwe nogushobora gukurura / kumanuka.
10-biti ADC hamwe no kwinjiza ibintu byinshi muri pin 8.
10-bit DAC.
Ibintu bine rusange bigamije igihe / kubara hamwe 8 byinjira hamwe na 10 ugereranya ibisubizo.Buri gihe cyigihe kigira umubare winjiza hanze.
Ibice bibiri bya PWM / ingengabihe hamwe ninkunga yo kugenzura ibyiciro bitatu.Buri PWM ifite ibyinjira byo hanze byinjira.
RTC hamwe nimbaraga zitandukanye.Inkomoko yisaha irashobora kuba oscillator ya RTC cyangwa isaha ya APB.
K 2 kB SRAM ikoreshwa na pin ya RTC, ituma amakuru abikwa mugihe chip zisigaye zashizwemo.
WatchDog Timer (WDT).WDT irashobora gukorerwa kuva muri oscillator y'imbere ya RC, oscillator ya RTC, cyangwa isaha ya APB.
Interineti isanzwe ya ARM ikizamini / gukuramo interineti kugirango ihuze nibikoresho bihari.
Kwigana kwigana module ishyigikira igihe nyacyo.
Imashanyarazi imwe 3.3 V itanga amashanyarazi (3.0 V kugeza 3.6 V).
Ibintu bine byagabanije imbaraga: ubusa, ibitotsi, imbaraga-hasi, nimbaraga-hasi.
Ibintu bine byo hanze byahagaritswe byinjira nkurugero / urwego rworoshye.Amapine yose ku cyambu 0 na port 2 arashobora gukoreshwa nkinkomoko yoroheje yo guhagarika isoko.
Gutunganya kubyuka biva muburyo bwa Power-down ukoresheje interineti iyo ari yo yose ishoboye gukora mugihe cya Power-down (harimo guhagarika hanze, guhagarika RTC, ibikorwa bya USB, guhagarika Ethernet guhagarika, ibikorwa bya bisi ya CAN, icyambu 0/2 pin guhagarika).Imbaraga ebyiri zigenga zitanga uburyo bwiza bwo gukoresha ingufu zishingiye kubintu bikenewe.
Buri periferiya ifite isaha igabanya amasaha yo gukomeza kuzigama ingufu.Abatandukanya bafasha kugabanya imbaraga zikora kuri 20% kugeza 30%.
Brownout itahura hamwe ninzira zinyuranye zo guhagarika no gusubiramo ku gahato.
Kuri-chip power-on reset. Kuri-chip kristal oscillator ifite intera ikora ya 1 MHz kugeza 25 MHz.
4 MHz y'imbere ya oscillator ya RC yagabanutse kugera kuri 1% byukuri bishobora gukoreshwa nkisaha ya sisitemu.Iyo ikoreshwa nkisaha ya CPU, ntabwo yemerera CAN na USB gukora.
Kuri-chip PLL yemerera imikorere ya CPU kugeza ku gipimo ntarengwa cya CPU idakeneye kristu yo hejuru.Irashobora gukoreshwa kuva oscillator nkuru, oscillator y'imbere, cyangwa oscillator ya RTC.
Gusikana imbibi zo gupima ikizamini cyoroshye.
Imikorere itandukanye ya pin imikorere ihitamo yemerera byinshi bishoboka gukoresha on-chip peripheral imikorere.
