Chithunzi cha LPC1227FBD64/301,1 IC MCU 32BIT 128KB FLASH 64LQFP

Kufotokozera

LPC122x imakulitsa kupitilira kwa microcontroller ya 32-bit ARM ya NXP ndikuyang'ana ntchito zosiyanasiyana zamafakitale m'mafakitale ndi makina opangira kunyumba.Kupindula ndi malangizo a ARM Cortex-M0 Thumb, LPC122x imakhala ndi makulidwe okwera mpaka 50% poyerekeza ndi ma 8/16-bit microcontroller omwe amagwira ntchito wamba.LPC122x ilinso ndi laibulale yokhazikika yochokera ku ROM ya Cortex-M0, yomwe imapereka kangapo kuchuluka kwa masamu amalaibulale opangidwa ndi mapulogalamu, komanso nthawi yodziwikiratu yophatikizika ndi kuchepetsedwa kwa ma code code.Kuchita bwino kwa ARM Cortex-M0 kumathandizanso kuti LPC122x ikhale ndi mphamvu zochepa pazogwiritsa ntchito zofanana.LPC122x imagwira ntchito pa CPU mafupipafupi mpaka 45 MHz.Amapereka zosankha zambiri za kukumbukira flash, kuchokera ku 32 kB mpaka 128 kB.Tsamba laling'ono la 512-byte kufufuta kwa kukumbukira kwa flash kumabweretsa zabwino zambiri zamapangidwe, monga kutsanzira bwino kwa EEPROM, chithandizo cha boot-load kuchokera ku mawonekedwe aliwonse a serial komanso kumasuka kwa pulogalamu yapamunda ndikuchepetsa zofunika pa-chip RAM buffer.Zowonjezera zotumphukira za LPC122x zimaphatikizanso 10-bit ADC, ofananitsa awiri okhala ndi zotulutsa zotulutsa, ma UART awiri, mawonekedwe a SSP / SPI, mawonekedwe amodzi a I2C-basi okhala ndi mawonekedwe a Fast-mode Plus, Windowed Watchdog Timer, woyang'anira DMA, injini ya CRC, zowerengera nthawi zinayi, 32-bit RTC, 1 % oscillator yamkati yopangira ma baud, ndi mapini mpaka 55 General Purpose I/O (GPIO).
