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

Kufotokozera

The Atmel® |SMART™ SAM R21 ndi ma microcontrollers amphamvu otsika omwe amagwiritsa ntchito purosesa ya 32-bit ARM® Cortex®-M0+ ndi transceiver yophatikizika yamphamvu yotsika kwambiri ya 2.4GHz ISM band.Zipangizo za SAM R21 zimapezeka m'mapaketi a 32- ndi 48-pini mpaka 256KB Flash, 32KB ya SRAM ndipo zikugwira ntchito pafupipafupi 48MHz ndikufikira 2.14 Coremark/MHz.Amapangidwira kusamuka kosavuta komanso kowoneka bwino kokhala ndi ma module ofanana, ma code ogwirizana a hex, mapu a adilesi ofanana ndi ma pini omwe amasamuka pakati pa zida zonse pamndandanda wazogulitsa.Zida zonse zikuphatikiza zotumphukira zanzeru komanso zosinthika, Atmel Event System yosainira ma inter-peripheral, komanso kuthandizira batani la capacitive touch, slider and wheel user interfaces.Zida za Atmel SAM R21 zimapereka izi: In-system programmable Flash, 12-channel direct memory access (DMA) controller, 12-channel Event System, controller interrupt controller, mpaka 28 programmable I/O pini, ultra-low power 2.4GHz ISM band transceiver yokhala ndi data ya 250kB/s, 32-bit real-time wotchi ndi kalendala, atatu 16-bit Timer/Counters (TC) ndi atatu 16-bit Timer/Counters for Control (TCC), pomwe iliyonse TC ikhoza kukhazikitsidwa kuti izichita ma frequency ndi ma waveform, nthawi yoyendetsera pulogalamu yolondola kapena kujambula kolowera ndi nthawi komanso kuchuluka kwa ma siginecha a digito.Ma TC amatha kugwira ntchito mu 8- kapena 16-bit mode, ma TC osankhidwa amatha kusinthidwa kuti apange 32-bit TC, ndipo ma Timer/Counters for Control atatu ali ndi ntchito zowonjezera zokongoletsedwa ndi injini, kuyatsa ndi ntchito zina zowongolera.Zotsatizanazi zimapereka mpata umodzi wokhazikika wa USB 2.0 ndi mawonekedwe a chipangizo;mpaka asanu ma seri Communication Modules (SERCOM) kuti aliyense akhoza kusinthidwa kuti akhale ngati USART, UART, SPI, I2C up 3.4MHz ndi LIN kapolo;mpaka 8 channel 350ksps 12-bit ADC yokhala ndi phindu lokonzekera komanso kuwonjezereka kwapadera ndi kutsika komwe kumathandizira mpaka 16-bit resolution, ma analogi awiri ofananira okhala ndi zenera, Peripheral Touch Controller imathandizira mpaka mabatani 48, masilayidi, mawilo ndi kuzindikira moyandikana;Programmable Watchdog Timer, chojambulira chabulauni ndi kubwezeretsanso mphamvu ndi pulogalamu yamapini awiri Serial Wire Debug (SWD) ndi mawonekedwe owongolera.
