ATSAMR21G18A-MU IC RF TxRx + MCU General ISM > 1GHz - 2.4GHz 48-VFQFN Exposed Pad

Tsanangudzo

The Atmel® |SMART™ SAM R21 nhevedzano yeakaderera-simba microcontrollers anoshandisa 32-bit ARM® Cortex®-M0+ processor uye yakabatanidzwa yekupedzisira-yakaderera simba 2.4GHz ISM bhendi transceiver.SAM R21 midziyo inowanikwa mu32- uye 48-pini mapakeji anosvika 256KB Flash, 32KB yeSRAM uye ari kushanda pamwero mukuru we48MHz uye anosvika 2.14 Coremark/MHz.Iwo akagadzirirwa nyore uye intuitive kutama ane akafanana peripheral modules, hex inoenderana kodhi, yakafanana mutsara kero mepu uye pini inoenderana nzira dzekufambisa pakati pezvishandiso zvese mumutsara wechigadzirwa.Zvese zvishandiso zvinosanganisira akangwara uye anochinjika peripherals, Atmel Chiitiko Sisitimu yekusaina-yepakati-yepakati, uye tsigiro yecapacitive yekubata bhatani, inotsvedza uye vhiri mushandisi nzvimbo.Iyo Atmel SAM R21 zvishandiso zvinopa zvinotevera maficha: In-system programmable Flash, gumi nemaviri-channel yakananga memory yekuwana (DMA) controller, gumi nemaviri-channel Chiitiko System, programmable inovhiringidza controller, anosvika makumi maviri nemasere programmable I/O pini, Ultra-yakaderera simba. 2.4GHz ISM band transceiver ine data rate ye250kB/s, 32-bit real-time wachi nekarenda, matatu 16-bit Timer/Counters (TC) uye matatu 16-bit Timer/Counters for Control (TCC), apo imwe neimwe. TC inogona kugadzirwa kuti iite frequency uye waveform chizvarwa, chaiyo chirongwa chekuita nguva kana kupinza kubatwa nenguva uye frequency kuyerwa kwemasaini edhijitari.Iwo maTC anogona kushanda mu8- kana 16-bit modhi, maTC akasarudzwa anogona kukandwa kuti aite 32-bit TC, uye matatu maTimer/Counters for Control ane mabasa akawedzerwa akagadziridzwa mota, mwenje uye mamwe mashandisiro ekutonga.Iwo akatevedzana anopa imwe yakazara-kumhanya USB 2.0 yakamisikidzwa host uye mudziyo interface;anosvika mashanu Serial Kukurukurirana Modules (SERCOM) iyo imwe neimwe inogona kugadzirwa kuti iite seUSART, UART, SPI, I2C up 3.4MHz uye LIN muranda;inosvika sere chiteshi 350ksps 12-bit ADC ine programmable kuwana uye sarudzo yakasarudzika uye decimation inotsigira kusvika ku16-bit resolution, maviri analogi anoenzanisa ane hwindo modhi, Peripheral Touch Controller inotsigira anosvika makumi mana nemasere mabhatani, masiraidhi, mavhiri uye pedyo nekunzwa;programmable Watchdog Timer, brown-out detector uye simba-on reset uye maviri-pini Serial Wire Debug (SWD) chirongwa uye debug interface.
