Whakaahuatanga
Te Atmel® |Ko te SMART™ SAM R21 he raupapa o nga microcontrollers iti-hiko e whakamahi ana i te 32-bit ARM® Cortex®-M0+ pūtukatuka me te hiko ultra-iti whakaurua 2.4GHz ISM band transceiver.Kei te waatea nga taputapu SAM R21 i roto i nga kohinga 32- me te 48-pin me te 256KB Flash, 32KB o te SRAM me te mahi i te auau teitei o 48MHz ka tae ki te 2.14 Coremark/MHz.He mea hoahoa mo te heke ngawari me te ngawari me nga waahanga taapiri riterite, he waehere hototahi hex, he mapi wahitau raina rite me nga huarahi heke hototahi i waenga i nga taputapu katoa o te raupapa hua.Ko nga taputapu katoa kei roto i nga taputapu mohio me te ngawari, te Atmel Event System mo te tohu tohu-a-roto, me te tautoko mo te paatene pa capacitive, rēreti me nga atanga kaiwhakamahi wira.Ko nga taputapu Atmel SAM R21 e whakarato ana i nga ahuatanga e whai ake nei: In-system programmable Flash, 12-channel direct memory access (DMA) controller, 12-channel Event System, programmable interrupted controller, up to 28 programmable I/O pins, ultra-iti te mana. 2.4GHz ISM band transceiver me te reiti raraunga o 250kB/s, 32-bit karaka me te maramataka, e toru 16-bit Timer/Counters (TC) me te toru 16-bit Timer/Counters for Control (TCC), kei reira ia Ka taea te whirihora a TC ki te whakaputa auau me te hanga ngaru, te wa tika o te whakatinanatanga o te hotaka, te hopu whakauru ranei me te ine i te waa me te auau o nga tohu matihiko.Ka taea e nga TC te mahi i roto i te aratau 8-, 16-bit ranei, ka taea e nga TC kua kowhiria te whakaheke hei hanga i te TC 32-bit, a ko nga Timer/Counters for Control e toru nga mahi kua arotauhia mo te motuka, rama me etahi atu tono whakahaere.Ko te raupapa e whakarato ana i te kaihautu USB 2.0 tere-katoa me te atanga taputapu;ki runga ki te rima Rangarangi Whakawhitiwhiti Whakawhitiwhiti (SERCOM) ka taea te whirihora i ia tangata hei mahi hei USART, UART, SPI, I2C ake 3.4MHz me LIN pononga;tae atu ki te waru hongere 350ksps 12-bit ADC me te taonga ka taea e te hotaka me te kowhiringa te taapiri me te whakahekenga e tautoko ana ki te taumira moka-16, e rua nga kaiwhakarite tairitenga me te aratau matapihi, Te Kaiwhakahaere Paa Pikitia e tautoko ana ki te 48 nga patene, nga rēreti, nga wira me te mohio tata;Ka taea e te Kaitiaki Tiaki Tiaki, te kaitirotiro parauri-waho me te taapiri hiko me te papatono Waea Rangatū (SWD) titi-rua me te atanga patuiro.
