ATSAMR21G18A-MU IC RF TxRx + MCU General ISM > 1GHz – 2.4GHz 48-VFQFN Papa Fa'aalia

Fa'amatalaga

Le Atmel® |SMART™ SAM R21 o se fa'asologa o microcontrollers maualalo le malosi o lo'o fa'aogaina ai le 32-bit ARM® Cortex®-M0+ processor ma le feso'ota'iga feso'ota'iga ultra-maualalo 2.4GHz ISM band transceiver.O lo'o maua masini SAM R21 i pusa 32- ma 48-pin ma e o'o atu i le 256KB Flash, 32KB o le SRAM ma o lo'o fa'agaoioia i le maualuga o le 48MHz ma o'o atu i le 2.14 Coremark/MHz.Ua mamanuina mo femalagaiga faigofie ma le faʻaogaina faʻatasi ma faʻaoga faʻaoga tutusa, faʻasologa o le hex, faʻafanua faʻafanua tutusa laina laina ma pine fetaui auala femalagaiga i le va o masini uma i le faasologa o oloa.O masini uma e aofia ai peripheral atamai ma fetuutuunai, Atmel Event System mo faʻailoga vaʻavaʻai, ma le lagolago mo le paʻi paʻu capacitive, faʻaseʻe ma uili faʻaogaina fesoʻotaʻiga.O masini Atmel SAM R21 e maua ai vaega nei: In-system programmable Flash, 12-channel direct memory access (DMA) controller, 12-channel Event System, programmable interrupt controller, e oo atu i le 28 programmable I/O pins, ultra-low power 2.4GHz ISM band transceiver ma se fua faatatau o le 250kB/s, 32-bit taimi moni ma kalena, tolu 16-bit Timer/Counter (TC) ma tolu 16-bit Timer/Counters for Control (TCC), lea e ta'itasi E mafai ona fa'atulagaina le TC e fa'atino ai taimi ma fa'atupu fa'aoso, sa'o le taimi o le fa'atinoina o polokalame po'o le pu'eina o fa'aoga ma le taimi ma le fuaina o fa'ailoga numera.O TCs e mafai ona faʻaogaina i le 8- poʻo le 16-bit mode, o TCs filifilia e mafai ona faʻapipiʻiina e fausia ai se 32-bit TC, ma le tolu Timer/Counters for Control ua faʻalauteleina galuega faʻapitoa mo afi, moli ma isi faʻatonuga.O le fa'asologa e tu'uina atu ai se tasi o le USB 2.0 fa'apipi'i fa'apipi'i fa'atasi ma fa'aoga masini;e oʻo atu i le lima Serial Communication Modules (SERCOM) e mafai ona faʻatulagaina taʻitasi e galue o se USART, UART, SPI, I2C i luga 3.4MHz ma LIN pologa;e oʻo atu i le valu alalaupapa 350ksps 12-bit ADC ma maua polokalame ma filifiliga oversampling ma decimation lagolago e oʻo atu i le 16-bit iugafono, lua analog comparators ma faamalama mode, Peripheral Touch Pule lagolago e oo atu i 48 faamau, sliders, uili ma lagona latalata;e mafai ona fa'apolokalameina Watchdog Timer, fa'ailoga lanu enaena ma le toe fa'aleleia o le mana ma le lua-pin Serial Wire Debug (SWD) polokalame ma le debug interface.
