♠LPC2468 Single-chip 16-bit/32-bit yaying'ono; 512 kB kung'anima, Efaneti, CAN, ISP/IAP, USB 2.0 chipangizo/host/OTG, kunja kukumbukira mawonekedwe
Ma Semiconductors a NXP adapanga LPC2468 microcontroller mozungulira 16-bit/32-bit ARM7TDM-S CPU core yokhala ndi zolumikizira zenizeni zenizeni zomwe zimaphatikizapo JTAG ndi trace ophatikizidwa. LPC2468 ili ndi 512 kB ya pa-chip yothamanga kwambirikukumbukira.
Kukumbukira kung'animaku kumaphatikizapo mawonekedwe apadera a 128-bit wide memory interface ndi ma accelerator accelerator omwe amathandizira CPU kuchita malangizo otsatizana kuchokera ku flash memory pamlingo wa wotchi ya 72 MHz. Mbali imeneyi ndikupezeka kokha pa LPC2000 ARM microcontroller banja la mankhwala.
LPC2468 imatha kutsata malangizo onse a 32-bit ARM ndi 16-bit Thumb. Kuthandizira kwa magawo awiri a malangizowo kumatanthauza kuti mainjiniya amatha kusankha kukhathamiritsa ntchito yawomwina magwiridwe antchito kapena kukula kwa ma code pamlingo wocheperako. Pakatikati pakuchita malangizo mu Thumb state imatha kuchepetsa kukula kwa ma code ndi kupitilira 30% ndikungotayika pang'ono pogwira ntchito pomwe mukuchita malangizo mu ARM state imakulitsa corentchito.
Microcontroller ya LPC2468 ndiyoyenera kugwiritsa ntchito njira zingapo zoyankhulirana. Zimaphatikizapo 10/100 Ethernet Media Access Controller (MAC), USB yothamanga kwambiri Chipangizo/Host/OTG Controller yokhala ndi 4 kB ya endpoint RAM, anayi.Ma UART, njira ziwiri za Controller Area Network (CAN), mawonekedwe a SPI, ma Synchronous Serial Ports (SSP), ma I2C atatu, ndi mawonekedwe a I2S. Kuthandizira kuphatikizika kwa ma serial communications interfaces ndi izizigawo; cholumikizira chamkati cha 4 MHz cholondola kwambiri, 98 kB ya RAM yonse yokhala ndi 64 kB ya SRAM yakumaloko, 16 kB SRAM ya Efaneti, 16 kB SRAM ya DMA yanthawi zonse, 2 kB ya SRAM yoyendetsedwa ndi batire, ndi Memory YakunjaWoyang'anira (EMC).
Izi zimapangitsa kuti chipangizochi chikhale choyenera pazipata zolumikizirana komanso zosinthira ma protocol. Kuphatikizana ndi zowongolera zambiri zoyankhulirana, kuthekera kosunthika kosunthika, ndi mawonekedwe amakumbukiro ndizosiyanasiyana.32-bit timer, 10-bit ADC, 10-bit DAC, ma unit awiri a PWM, mapini anayi osokoneza kunja, ndi mizere yofulumira ya 160 ya GPIO.
LPC2468 imalumikiza zikhomo 64 za GPIO ku zida za Vector Interrupt Controller (VIC) zomwe zikutanthauza izi.zolowetsa zakunja zimatha kusokoneza zosokoneza. Zonsezi zimapangitsa LPC2468 kukhala yoyenera kuwongolera mafakitale ndi machitidwe azachipatala.
Purosesa ya ARM7TMI-S, yothamanga mpaka 72 MHz.
512 kB on-chip flash programme memory yokhala ndi In-System Programming (ISP) ndi In-Application Programming (IAP). Memory programme ya Flash ili pa basi ya ARM yakumaloko kuti igwire bwino ntchito ya CPU.
98 kB pa-chip SRAM imaphatikizapo:
64 kB ya SRAM pa basi ya ARM yakumaloko kuti mugwire ntchito kwambiri ndi CPU.
16 kB SRAM ya mawonekedwe a Efaneti. Itha kugwiritsidwanso ntchito ngati cholinga cha SRAM.
16 kB SRAM pazifukwa zambiri kugwiritsa ntchito DMA kumafikirikanso ndi USB.
Kusungidwa kwa data kwa 2 kB SRAM koyendetsedwa ndi mphamvu ya Real-Time Clock (RTC).
Dongosolo la Dual Advanced High-performance Bus (AHB) limalola nthawi yomweyo Ethernet DMA, USB DMA, ndikuchita pulogalamu kuchokera pa-chip flash popanda mkangano.
EMC imapereka chithandizo chazida zokumbukira zosasinthika monga RAM, ROM ndi flash, komanso kukumbukira kwamphamvu monga SDRAM ya data imodzi.
Advanced Vectored Interrupt Controller (VIC), yomwe imathandizira mpaka 32 zosokoneza.
General Purpose DMA controller (GPDMA) pa AHB yomwe ingagwiritsidwe ntchito ndi SSP, I 2S-bus, ndi SD/MMC mawonekedwe komanso kusamutsa kukumbukira-to-memory.
Mawonekedwe a seri:
Efaneti MAC yokhala ndi mawonekedwe a MII/RMII komanso wowongolera wa DMA. Ntchito izi zimakhala pa AHB yodziyimira payokha.
USB 2.0 chowongolera chothamanga chapawiri chapawiri/cholandira/OTG chokhala ndi pa-chip PHY komanso chowongolera cha DMA.
Ma UART anayi okhala ndi mtundu wa baud rate, imodzi yokhala ndi modem control I/O, imodzi yokhala ndi chithandizo cha IrDA, yonse yokhala ndi FIFO.
CAN chowongolera chokhala ndi njira ziwiri.
Wowongolera wa SPI.
Owongolera awiri a SSP, okhala ndi FIFO ndi kuthekera kwamitundu yambiri. Imodzi ndi njira ina ya doko la SPI, kugawana kusokoneza kwake. Ma SSP atha kugwiritsidwa ntchito ndi wowongolera GPDMA.
Malo atatu a mabasi a I2C (imodzi yokhala ndi zotsegula ndipo ziwiri zokhala ndi zikhomo zokhazikika).
Mawonekedwe a I 2S (Inter-IC Sound) pazolowetsa kapena zotulutsa za digito. Itha kugwiritsidwa ntchito ndi GPDMA.
Zotumphukira zina:
SD/MMC memory card interface.
160 Zikhomo za I/O zokhala ndi zopinga zosinthika zokokera mmwamba/pansi.
10-bit ADC yokhala ndi kuchulukitsa kowonjezera pakati pa mapini 8.
10-bit DAC.
Zowerengera nthawi / zowerengera zanthawi zonse zokhala ndi zolowetsa 8 ndi 10 kufananiza zotuluka. Chowerengera chilichonse chimakhala ndi chowerengera chakunja.
Ma block awiri a PWM/timer okhala ndi chithandizo chowongolera ma mota a magawo atatu. PWM iliyonse imakhala ndi zowerengera zakunja.
RTC yokhala ndi mphamvu yosiyana. Gwero la wotchi litha kukhala RTC oscillator kapena wotchi ya APB.
2 kB SRAM yoyendetsedwa ndi pini yamagetsi ya RTC, kulola kuti data isungidwe chip chikazimitsidwa.
WatchDog Timer (WDT). WDT imatha kutsekedwa kuchokera ku RC oscillator yamkati, oscillator ya RTC, kapena wotchi ya APB.
Mayeso oyeserera a ARM/mawonekedwe owongolera kuti agwirizane ndi zida zomwe zilipo.
Emulation trace module imathandizira kufufuza nthawi yeniyeni.
Mphamvu imodzi ya 3.3 V (3.0 V mpaka 3.6 V).
Mitundu inayi yochepetsera mphamvu: osagwira ntchito, kugona, kutsika, komanso kutsika kwakuya.
Zolowa zinayi zosokoneza zakunja zomwe zingasinthidwe ngati m'mphepete / mulingo. Zikhomo zonse zomwe zili padoko 0 ndi doko 2 zitha kugwiritsidwa ntchito ngati magwero osokoneza.
Kudzutsidwa kwa purosesa kuchokera ku Power-down mode kudzera muzosokoneza zilizonse zomwe zimatha kugwira ntchito panthawi ya Power-down (kuphatikiza zosokoneza zakunja, kusokoneza kwa RTC, ntchito ya USB, kusokoneza kwa Ethernet kudzutsa, zochitika za basi za CAN, kusokoneza kwa 0/2 pini). Madomeni awiri odziyimira pawokha amalola kukonza bwino kagwiritsidwe ntchito ka mphamvu kutengera zofunikira.
Zotumphukira zilizonse zimakhala ndi chogawira wotchi yake kuti muwonjezere kupulumutsa mphamvu. Ogawa awa amathandizira kuchepetsa mphamvu yogwira ntchito ndi 20% mpaka 30%.
Browout zindikirani ndi ziwopsezo zosiyana kuti musokoneze ndikukakamizanso.
Kukhazikitsanso mphamvu pa-chip. On-chip crystal oscillator yokhala ndi 1 MHz mpaka 25 MHz.
4 MHz mkati mwa RC oscillator yokonzedwa ku 1 % kulondola komwe kungagwiritsidwe ntchito ngati wotchi yamakina. Mukagwiritsidwa ntchito ngati wotchi ya CPU, salola CAN ndi USB kuti ziyende.
On-chip PLL imalola CPU kuti igwire ntchito mpaka pamlingo wapamwamba kwambiri wa CPU popanda kufunikira kwa kristalo wapamwamba kwambiri. Itha kuyendetsedwa kuchokera ku oscillator yayikulu, oscillator yamkati ya RC, kapena oscillator ya RTC.
Kusanthula malire kwa kuyezetsa bolodi kosavuta.
Zosankha za pini zosinthika zimalola mwayi wambiri wogwiritsa ntchito zotumphukira za pa-chip.
