♠LPC2468 I-Single-chip 16-bit/32-bit micro; 512 kB flash, Ethernet, CAN, ISP/IAP, USB 2.0 idivayisi/host/OTG, inkumbulo yangaphandle interface
Ama-Semiconductors e-NXP adizayine i-LPC2468 microcontroller eduze kwe-16-bit/32-bit ARM7TDM-S CPU core enokusebenzelana kokususa iphutha kwesikhathi sangempela okufaka kokubili i-JTAG nokulandelela okushumekiwe. I-LPC2468 ino-512 kB we-on-chip high-speed flashinkumbulo.
Le nkumbulo ye-flash ihlanganisa isixhumi esibonakalayo esikhethekile senkumbulo ebanzi engu-128-bit kanye nesakhiwo se-accelerator esivumela i-CPU ukuthi isebenzise imiyalo elandelanayo esuka kumemori ye-flash ngezinga eliphezulu lewashi lesistimu engu-72 MHz. Lesi siciitholakala kuphela kumndeni wemikhiqizo ye-LPC2000 ARM microcontroller.
I-LPC2468 ingakwazi ukusebenzisa kokubili i-32-bit ARM kanye nemiyalelo ye-Thumb engu-16-bit. Ukusekelwa kwamasethi amabili wemiyalo kusho ukuthi onjiniyela bangakhetha ukuthuthukisa isicelo sabokungaba ukusebenza noma usayizi wekhodi ezingeni le-sub-routine. Uma umongo ukhipha imiyalelo kusimo sesithupha unganciphisa usayizi wekhodi ngaphezu kuka-30 % ngokulahleka okuncane kuphela ekusebenzeni ngenkathi kusetshenziswa imiyalelo kusimo se-ARM kukhulisa umgogodla.ukusebenza.
Isilawuli esincane se-LPC2468 silungele izinhlelo zokusebenza zokuxhumana ezinezinjongo eziningi. Ihlanganisa i-10/100 Ethernet Media Access Controller (MAC), Isilawuli se-USB esigcwele isivinini Sedivayisi/Umsingathi/OTG esino-4 kB we-endpoint RAM, ezine.Ama-UART, iziteshi ezimbili ze-Controller Area Network (CAN), isixhumi esibonakalayo se-SPI, Izimbobo ezimbili ze-Synchronous Serial (SSP), izixhumanisi ezintathu ze-I2C, kanye nesixhumi esibonakalayo se-I2S. Ukusekela leli qoqo lezixhumi ezibonakalayo zezokuxhumana isici esilandelayoizingxenye; i-oscillator enembile engu-4 MHz yangaphakathi, 98 kB wesamba se-RAM ehlanganisa u-64 kB we-SRAM yasendaweni, 16 kB SRAM ye-Ethernet, 16 kB SRAM ngenjongo evamile ye-DMA, 2 kB ye-SRAM esebenza ngebhethri, kanye Nenkumbulo YangaphandleIsilawuli (EMC).
Lezi zici zenza le divayisi ifaneleke ngokufanelekile kumasango okuxhumana neziguquli zephrothokholi. Ukugcwalisa izilawuli eziningi zokuxhumana ze-serial, amakhono wewashi ahlukahlukene, kanye nezici zenkumbulo kuyahlukahluka.Izibali sikhathi ezingama-32-bit, i-10-bit ADC ethuthukisiwe, i-10-bit DAC, amayunithi amabili e-PWM, izikhonkwane ezine eziphazamisayo zangaphandle, kanye nemigqa efika ku-160 esheshayo ye-GPIO.
I-LPC2468 ixhuma izikhonkwane ezingu-64 ze-GPIO ku-hardware based Vector Interrupt Controller (VIC) okusho ukuthi leziokokufaka kwangaphandle kungadala iziphazamiso ezicushwe emaphethelweni. Zonke lezi zici zenza i-LPC2468 ifaneleke kakhulu ukulawula izimboni nezinhlelo zezokwelapha.
Iphrosesa ye-ARM7TMI-S, isebenza kufika ku-72 MHz.
512 kB inkumbulo yohlelo lwe-chip flash enekhono lokuHlela Kwangaphakathi (ISP) kanye Nohlelo Lokusebenza Kwangaphakathi (IAP). Imemori yohlelo lwe-Flash isebhasini lendawo le-ARM ukuze ifinyelele ukusebenza okuphezulu kwe-CPU.
98 kB on-chip SRAM ihlanganisa:
64 kB we-SRAM ebhasini lendawo le-ARM ukuze uthole ukufinyelela kwe-CPU esebenza kahle.
16 kB SRAM yesixhumi esibonakalayo se-Ethernet. Ingasetshenziswa futhi njengenhloso evamile ye-SRAM.
16 kB SRAM ngenjongo evamile ukusetshenziswa kwe-DMA nakho kufinyeleleka nge-USB.
2 kB isitoreji sedatha ye-SRAM sinikwe amandla kusukela kusizinda samandla sewashi lesikhathi sangempela (RTC).
Uhlelo lwe-Dual Advanced High-performance Bus (AHB) luvumela i-Ethernet DMA, i-USB DMA, kanye nokusebenzisa uhlelo ku-on-chip flash ngaphandle kokungqubuzana.
I-EMC inikeza ukusekelwa kwamadivayisi enkumbulo emile asynchronous njenge-RAM, i-ROM ne-flash, kanye nezinkumbulo ezinamandla ezifana nesilinganiso sedatha eyodwa ye-SDRAM.
Isilawuli Se-Advanced Vectored Interrupt (VIC), esisekela iziphazamiso ezinama-vector ezingafika kwezingama-32.
Isilawuli se-DMA Yenhloso Ejwayelekile (i-GPDMA) ku-AHB engasetshenziswa ne-SSP, i-I 2S-bus, ne-SD/MMC interface kanye nokudluliswa kwenkumbulo kuya kwinkumbulo.
I-Serial Interfaces:
I-Ethernet MAC ene-MII/RMII interface nesilawuli se-DMA esihlobene. Le misebenzi ihlala ku-AHB ezimele.
Isilawuli se-USB 2.0 esinesivinini esigcwele sembobo ekabili/umsingathi/i-OTG esine-PHY eku-chip nesilawuli se-DMA esihlobene.
Ama-UART amane akhiqiza isilinganiso se-baud esiyingxenye, eyodwa enolawulo lwemodemu I/O, eyodwa enosekelo lwe-IrDA, wonke ane-FIFO.
CAN isilawuli esinamashaneli amabili.
Isilawuli se-SPI.
Izilawuli ezimbili ze-SSP, ezinamakhono e-FIFO kanye namaphrothokholi amaningi. Enye ingenye yembobo ye-SPI, yabelana ngokuphazamiseka kwayo. Ama-SSP angasetshenziswa nesilawuli se-GPDMA.
Izindawo ezintathu zokuhlangana zamabhasi e-I2C (eyodwa ene-open-drain nezimbili ezinamaphinikhodi ajwayelekile).
I-I 2S (Inter-IC Sound) isixhumi esibonakalayo sokufakwayo komsindo wedijithali noma okukhiphayo. Ingasetshenziswa ne-GPDMA.
Amanye ama-peripherals:
Isixhumi esibonakalayo sekhadi lememori ye-SD/MMC.
160 Izikhonkwane zenhloso ezijwayelekile ze-I/O ezinamaphini okudonsela phezulu/phansi alungisekayo.
I-10-bit ADC enokufakwa kokuphindaphinda phakathi kwamaphini angu-8.
I-10-bit DAC.
Izibali-sikhathi ezine zenhloso ejwayelekile/izinto zokubala ezinokufakwa kokuthwebula okungu-8 kanye nokuphumayo okuqhathanisayo okungu-10. Ibhulokhi ngayinye yesikhathi inokufakwayo kokubala kwangaphandle.
Amabhulokhi amabili e-PWM/timer anosekelo lokulawulwa kwenjini okunezigaba ezintathu. I-PWM ngayinye inokufakwayo kokubala kwangaphandle.
I-RTC enesizinda samandla esihlukene. Umthombo wewashi kungaba i-oscillator ye-RTC noma iwashi le-APB.
2 kB SRAM inikwe amandla iphinikhodi yamandla ye-RTC, evumela idatha ukuthi igcinwe lapho yonke chip ivaliwe.
I-WatchDog Timer (WDT). I-WDT ingenziwa iwashi kusukela ku-oscillator ye-RC yangaphakathi, i-oscillator ye-RTC, noma iwashi le-APB.
Ukuhlola okujwayelekile kwe-ARM/ukulungisa iphutha ukuze kuhambisane namathuluzi akhona.
Imojula yokulandela umkhondo yokulingisa isekela ukulandelela kwesikhathi sangempela.
Ukunikezwa kwamandla kagesi okungu-3.3 V okukodwa (3.0 V kuya ku-3.6 V).
Izindlela zamandla ezine ezincishisiwe: ukungenzi lutho, ukulala, ukwehlisa amandla, kanye nokwehlisa amandla ajulile.
Okokufaka okune kokuphazamiseka kwangaphandle okulungisekayo njengokuzwela komphetho/izinga. Wonke amaphini ku-port 0 kanye ne-port 2 angasetshenziswa njengemithombo yokuphazamiseka ebucayi ebucayi.
Ukuvuka kwephrosesa kusuka kumodi yokuya phansi nganoma yikuphi ukuphazamiseka okukwazi ukusebenza phakathi nemodi yokuwa phansi (kufaka phakathi iziphazamiso zangaphandle, ukuphazamiseka kwe-RTC, umsebenzi we-USB, ukuphazamiseka kokuvuka kwe-Ethernet, umsebenzi webhasi le-CAN, imbobo engu-0/2 yokuphazamiseka kwephinikhodi). Izizinda zamandla ezimbili ezizimele zivumela ukulungiswa kahle kokusetshenziswa kwamandla ngokusekelwe kuzici ezidingekayo.
I-peripheral ngayinye inewashi layo lokuhlukanisa iwashi lokulondoloza amandla okwengeziwe. Lezi zihlukanisi zisiza ukunciphisa amandla asebenzayo ngo-20 % kuya ku-30 %.
I-Brownout ibona ngemikhawulo ehlukene ukuze uphazamiseke futhi umiswe kabusha ngempoqo.
Ukusetha kabusha amandla ku-chip. I-On-chip crystal oscillator enobubanzi bokusebenza obungu-1 MHz ukuya ku-25 MHz.
I-oscillator ye-RC yangaphakathi engu-4 MHz esikwe yaba ngu-1 % ukunemba okungasetshenziswa ngokuzithandela njengewashi lesistimu. Uma isetshenziswa njengewashi le-CPU, ayivumeli i-CAN ne-USB ukuthi zisebenze.
I-On-chip PLL ivumela ukusebenza kwe-CPU kuze kufike kusilinganiso esiphezulu se-CPU ngaphandle kwesidingo sekristalu yefrikhwensi ephezulu. Ingase isetshenziswe isuka ku-oscillator eyinhloko, i-oscillator ye-RC yangaphakathi, noma i-oscillator ye-RTC.
Ukuskena komngcele wokuhlolwa kwebhodi okwenziwe lula.
Ukukhethwa komsebenzi wephinikhodi okuhlukahlukene kuvumela amathuba amaningi okusebenzisa imisebenzi ye-peripheral eku-chip.
