Chithunzi cha LPC2148FBD64,151 IC MCU 16/32B 512KB FLASH 64LQFP

Kufotokozera

Ma microcontrollers a LPC2141/42/44/46/48 amachokera ku 16-bit/32-bit ARM7TDMI-S CPU yokhala ndi kutsanzira kwanthawi yeniyeni komanso chithandizo chophatikizika, chomwe chimaphatikiza chowongolera chowongolera ndi kukumbukira kothamanga kwambiri kuyambira 32. kB mpaka 512 kB.Mawonekedwe a 128-bit wide memory memory ndi mawonekedwe apadera a accelerator amathandizira kupha ma code 32-bit pamlingo wokwera kwambiri.Pogwiritsa ntchito ma code ovuta kwambiri, njira ina ya 16-bit Thumb imachepetsa kachidindo ndi 30% ndi chilango chochepa.Chifukwa cha kukula kwawo kakang'ono komanso kugwiritsa ntchito mphamvu zochepa, LPC2141/42/44/46/48 ndi yabwino kwa mapulogalamu omwe miniaturization ndiyofunika kwambiri, monga kuwongolera mwayi ndi malo ogulitsa.Njira zoyankhulirana za seriyo kuyambira pa chipangizo cha USB 2.0 chothamanga kwambiri, ma UART angapo, SPI, SSP kupita ku I2C-basi ndi pa-chip SRAM ya 8 kB mpaka 40 kB, zimapangitsa kuti zipangizozi zikhale zoyenera kwambiri pazipata zoyankhulirana ndi zosinthira ma protocol, zofewa. ma modemu, kuzindikira kwamawu ndi kuyerekeza kotsika, kumapereka kukula kwakukulu kwa buffer komanso mphamvu yayikulu yopangira.Zowerengera zosiyanasiyana za 32-bit, imodzi kapena ziwiri za 10-bit ADC(s), 10-bit DAC, PWM njira ndi mizere 45 yothamanga ya GPIO yokhala ndi mapini opitilira asanu ndi anayi kapena osawoneka bwino akunja amapangitsa kuti ma microcontroller awa akhale oyenera kuwongolera mafakitale ndi machitidwe azachipatala. .
