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

Kufotokozera

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 high-speed flash memory.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.Izi zimapezeka kokha pagulu la LPC2000 ARM microcontroller lazinthu.LPC2468 imatha kutsata malangizo onse a 32-bit ARM ndi 16-bit Thumb.Kuthandizira magawo awiri a malangizowa kumatanthauza kuti mainjiniya amatha kusankha kukhathamiritsa ntchito yawo pakuchita bwino 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 pakugwirira ntchito pomwe mukuchita malangizo m'boma la ARM kumakulitsa magwiridwe antchito.Microcontroller ya LPC2468 ndiyoyenera kugwiritsa ntchito njira zingapo zoyankhulirana.Zimaphatikizapo 10/100 Ethernet Media Access Controller (MAC), USB full-speed Device/Host/OTG Controller yokhala ndi 4 kB ya endpoint RAM, ma UART anayi, njira ziwiri za Controller Area Network (CAN), mawonekedwe a SPI, awiri Synchronous. Ma Seri Ports (SSP), mawonekedwe atatu a I2C, ndi mawonekedwe a I2S.Kuthandizira kusonkhanitsa kwa ma serial communications interfaces ndi zigawo zotsatirazi;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 pazifukwa zonse DMA, 2 kB ya SRAM yoyendetsedwa ndi batire, ndi Wowongolera Memory Wakunja ( EMC).Izi zimapangitsa kuti chipangizochi chikhale choyenera pazipata zolumikizirana komanso zosinthira ma protocol.Kuthandizira zowongolera zambiri zoyankhulirana, kutha kwa mawotchi osunthika, ndi zokumbukira zosiyanasiyana 32-bit timer, 10-bit ADC, 10-bit DAC, mayunitsi awiri a PWM, mapini anayi osokoneza akunja, ndi mizere yofulumira ya 160 ya GPIO.LPC2468 imagwirizanitsa 64 ya zikhomo za GPIO ku hardware yochokera ku Vector Interrupt Controller (VIC) zomwe zikutanthauza kuti zolowetsa zakunjazi zimatha kusokoneza zosokoneza.Zonsezi zimapangitsa LPC2468 kukhala yoyenera kuwongolera mafakitale ndi machitidwe azachipatala.
