ATSAMD21E18A-MU IC MCU 32BIT 256KB FLASH 32QFN

Sharaxaada

SAM D21/DA1 waa taxane awood yar oo awood yar ah oo isticmaalaya 32-bit Arm® Cortex®-M0+ processor, oo u dhexeeya 32-biin ilaa 64-pins oo wata ilaa 256 KB Flash iyo 32 KB ee SRAM.SAM D21/DA1 wuxuu ku shaqeeyaa inta jeer ee ugu badan ee 48 MHz wuxuuna gaaraa 2.46 CoreMark/MHz.Waxaa loo qaabeeyey guuritaan fudud oo dareen leh oo leh qaybo isku mid ah oo durugsan, kood ku habboon hex, khariidadda ciwaanka toosan ee isku midka ah, iyo dariiqyada socdaalka ku habboon ee u dhexeeya dhammaan aaladaha taxanaha alaabta.Qalabyada oo dhan waxa ka mid ah meelaha garaadka iyo dabacsanaanta leh, Nidaamka Dhacdada ee calaamadaynta dhex dhexaadinta, iyo taageerada badhanka taabashada awoodda leh, slider-ka, iyo is-dhexgalka isticmaalaha giraangiraha.SAM D21/DA1 waxa ay bixisaa sifooyinka soo socda: In-system Flash programmable, 12-channel Direct Memory Access Controller (DMAC), 12-channel System Event System, Programmable Controller Interrupt Controller. -Time Clock iyo Calendar (RTC), ilaa shan 16-bit Timer/Counters (TC) iyo ilaa afar 24-bit Timer/Counters for Control (TCC), halkaas oo TC kasta loo habayn karo si uu u qabto soo noqnoqoshada iyo jiilka hirka, wakhtiga fulinta barnaamijka saxda ah ama qabashada galinta oo leh wakhtiga iyo qiyaasta inta jeer ee calaamadaha dhijitaalka ah.TC-yadu waxay ku shaqayn karaan qaab 8-bit ama 16-bit ah, TC-yada la xushay waa lagu shubi karaa si ay u sameeyaan 32-bit TC, iyo saddex timer/counter-yada waxay leeyihiin hawlo la dheereeyey oo loogu talagalay matoorka, nalka, iyo codsiyada kale ee xakamaynta.Taxanuhu wuxuu bixiyaa hal xawli buuxa oo USB 2.0 ah oo kuxiran martigeliyaha iyo isdhexgalka aaladda;Ilaa lix Module Isgaarsiineed Serial (SERCOM) oo mid walba loo habeyn karo inuu u dhaqmo sida USART, UART, SPI, I2C ilaa 3.4 MHz, SMBus, PMBus, iyo LIN;laba-channel I 2S interface;ilaa labaatan kanaal 350 ksps 12-bit ADC oo leh faa'iido barnaamij la heli karo iyo xad dhaafka ikhtiyaariga ah iyo dhimista taageeraya ilaa 16-bit xallinta, hal 10-bit 350 ksps DAC, ilaa afar isbarbardhigyaal analoog leh oo leh qaabka daaqada, Peripheral Touch Controller (PTG) taageeraya ilaa 256 badhamada, sliders, wheels, iyo u dhawaanshaha;Saacadaha Watchdog Timer (WDT), baaraha-brown-ka-baxsan iyo dib-u-dejinta awoodda iyo barnaamijka laba-pin Serial Wire Debug (SWD) iyo interface-ka cilladaha.Dhammaan qalabku waxay leeyihiin oscillators dibadda iyo gudaha ah oo sax ah oo hooseeya.Dhammaan oscillator-yada waxaa loo isticmaali karaa isha saacadda nidaamka.Qaybaha saacadaha kala duwan ayaa si madaxbanaan loogu habayn karaa inay ku shaqeeyaan mawjadaha kala duwan, taas oo awood u siinaysa badbaadinta tamarta adoo ku socodsiinaya meel kasta inta jeer ee ugu fiican, oo sidaas awgeed la ilaaliyo soo noqnoqoshada CPU sare iyada oo la dhimayo isticmaalka tamarta.
