LPC2468FBD208,551 IC MCU 16/32B 512KB FLSH 208LQFP

Sharaxaada

Semiconductors NXP waxay u qaabeeyeen LPC2468 microcontroller ku wareegsan 16-bit/32-bit ARM7TDMI-S CPU core oo leh is-dhexgal-waqtiga-dhabta ah ee khaladka ah oo ay ku jiraan labadaba JTAG iyo raad-raacyo guntan.LPC2468 waxay haysataa 512 kB ee ku-chip xusuusta flash-xawaare sare.Xusuusta flash-kan waxa ka mid ah interface 128-bit oo ballaadhan oo xusuusta ah iyo qaab-dhismeed dardar-gelineed oo awood u siinaya CPU-gu inuu fuliyo awaamiir taxane ah oo ka imanaya xusuusta flash-ka ugu badnaan 72 MHz heerka saacadda nidaamka.Habkan waxa laga heli karaa oo keliya LPC2000 ARM microcontroller qoyska alaabta.LPC2468 waxay fulin kartaa labadaba 32-bit ARM iyo 16-bit tilmaamaha Suulka.Taageerada labada hab ee tilmaamuhu waxay ka dhigan tahay in injineerada ay dooran karaan inay kor u qaadaan codsigooda waxqabad ama cabbirka koodka ee heerka caadiga ah.Marka xudunta udub dhexaad u fuliso tilmaamaha gobolka Thumb waxa ay yarayn kartaa cabbirka koodka in ka badan 30 % iyada oo kaliya khasaare yar oo waxqabadka ah halka fulinta awaamiirta gobolka ARM ay kor u qaadayso waxqabadka asaasiga ah.LPC2468 microcontroller ayaa u fiican codsiyada isgaarsiinta ujeedooyinka badan.Waxay ku daraysaa 10/100 Ethernet Media Access Controller (MAC), Aaladda xawaaraha buuxa ee USB / Martigeliyaha / OTG Controller oo leh 4 kB ee RAM dhamaadka, afar UARTs, laba kanaal aagga Controller Area Network (CAN), interface SPI, laba Synchronous Serial Ports (SSP), saddex I2C interfaces, iyo interface I2S ah.Taageerida ururintan isgaadhsiinta isgaadhsiinta ee taxanaha ah waa qaybaha soo socda ee muujinta;Qalabka saxda ah ee gudaha 4 MHz, 98 kB wadarta RAM oo ka kooban 64 kB ee SRAM maxalliga ah, 16 kB SRAM ee Ethernet, 16 kB SRAM oo ujeedo guud ah DMA, 2 kB oo batari ku shaqeeya SRAM, iyo Xakameeyaha xusuusta dibadda ( EMC).Astaamahan ayaa ka dhigaya qalabkan mid ku habboon albaabbada isgaarsiinta iyo beddelayaasha borotokoolka.Buuxinta kontaroolayaasha isgaarsiineed ee taxanaha ah, awoodaha saacadaha badan ee kala duwan, iyo astaamaha xusuusta ayaa ah saacadaha 32-bit ee kala duwan, 10-bit ADC oo la hagaajiyay, 10-bit DAC, laba unug PWM, afar biin oo dibadda ah, iyo ilaa 160 xariiqyo GPIO ah oo degdeg ah.LPC2468 waxay ku xidhaa 64 ka mid ah biinanka GPIO-ga qalabka ku salaysan ee Vector Interrupt Controller (VIC) taas oo macnaheedu yahay agabyadan dibeda ahi waxay dhalin karaan carqalado kiciyey geesaha.Dhammaan sifooyinkan ayaa ka dhigaya LPC2468 si gaar ah ugu habboon xakamaynta warshadaha iyo nidaamyada caafimaadka.
