Chithunzi cha AT91SAM9261B-CU IC MCU 32BIT 32KB ROM 217BGA

Kufotokozera

AT91SAM9261 ndi pulogalamu yathunthu pa-chip yomwe idamangidwa mozungulira purosesa ya ARM926EJ-S ARM Thumb yokhala ndi malangizo owonjezera a DSP ndi Jazelle Java accelerator.Imakwaniritsa 210 MIP pa 190 MHz.AT91SAM9261 ndi purosesa yokhathamiritsa yamapulogalamu omwe ali ndi chiwonetsero cha LCD.Wowongolera wake wa LCD wophatikizika amathandizira BW mpaka mtundu wa 16M, zowonetsa zogwira ntchito komanso zopanda pake za LCD.160 Kbyte Integrated SRAM ikhoza kukhazikitsidwa ngati chotchingira chimango chochepetsera kutsitsimuka kwa LCD pakuchita kwa purosesa yonse.Chiyankhulo cha Mabasi Akunja chimaphatikizapo olamulira a synchronous DRAM (SDRAM) ndi zokumbukira zokhazikika ndipo zimakhala ndi mawonekedwe ozungulira a CompactFlash ndi NAND Flash.AT91SAM9261 imaphatikiza ROM yochokera ku Boot Loader yothandizira ma code shadowing kuchokera, mwachitsanzo, kunja kwa DataFlash® kupita ku SDRAM yakunja.Pulogalamu yoyendetsedwa ndi Power Management Controller (PMC) imapangitsa kuti magetsi azigwiritsidwa ntchito pang'onopang'ono posankha / kuletsa purosesa ndi zotumphukira zosiyanasiyana ndikusintha ma frequency ogwiritsira ntchito.AT91SAM9261 imapindulanso ndi kuphatikizika kwa zinthu zambiri zosokoneza kuphatikiza JTAG-ICE, njira yodzipatulira ya UART (DBGU) komanso kutsata nthawi yeniyeni.Izi zimathandizira kukonza ndi kukonza mapulogalamu onse, makamaka omwe ali ndi zovuta zenizeni.
