Whakaahuatanga
Ko te SAM D21/DA1 he raupapa o nga microcontrollers iti-hiko e whakamahi ana i te 32-bit Arm® Cortex®-M0+ pūtukatuka, me te mai i te 32-titi ki te 64-pin me te 256 KB Flash me te 32 KB o te SRAM.Ko te SAM D21/DA1 e mahi ana i te auau teitei o 48 MHz ka tae ki te 2.46 CoreMark/MHz.He mea hoahoa mo te heke ngawari me te ngawari me nga waahanga taapiri riterite, he waehere hototahi hex, he mahere wahitau rarangi rite, me nga huarahi heke hototahi i waenga i nga taputapu katoa o te raupapa hua.Kei roto i nga taputapu katoa nga taputapu mohio me te ngawari, te Pūnaha Takahanga mo te tohu tohu-a-taiao, me te tautoko mo te paatene pa capacitive, rēreti, me nga atanga kaiwhakamahi wira.Ko te SAM D21/DA1 e whakarato ana i nga ahuatanga e whai ake nei: In-system programmable Flash, 12-channel Direct Memory Access Controller (DMAC), 12-channel Event System, programmable Interrupt Controller, ki te 52 programmable I/O pins, 32-bit Real -Karaka Wā me te Maramataka (RTC), tae atu ki te rima 16-bit Timer/Counter (TC) tae atu ki te wha 24-bit Timer/Counters for Control (TCC), ka taea te whirihora ia TC ki te mahi auau me te hanga ngaru, te wa tika o te whakatinanatanga o te hotaka, te hopu whakauru ranei me te inenga wa me te auau o nga tohu matihiko.Ka taea e nga TC te mahi i roto i te aratau 8-bit, 16-bit ranei, ko nga TC kua tohua ka taea te whakaheke hei hanga i te TC 32-bit, a e toru nga taima/counter kua whakaroahia nga mahi kua arotauhia mo te motuka, rama, me etahi atu tono whakahaere.Ko te raupapa e whakarato ana i te USB 2.0 tere katoa te kaihautu me te atanga taputapu;tae atu ki te ono nga Whakawhitiwhiti Whakawhitiwhiti Rangatū (SERCOM) ka taea te whirihora i ia tangata ki te mahi hei USART, UART, SPI, I2C ki runga ki te 3.4 MHz, SMBus, PMBus, me te kiritaki LIN;rua-hongere atanga I 2S;tae atu ki te rua tekau ma rua nga hongere 350 ksps 12-bit ADC me te hua ka taea e te hotaka me te kowhiringa te taapiri me te whakahekenga e tautoko ana ki te taumira moka-16, kotahi moka-10 350 ksps DAC, tae atu ki te wha nga kaiwhakariterite tairitenga me te aratau Matapihi, Kaiwhakahaere Paa Pikitia (PTG) e tautoko ana ki te 256 nga patene, nga riipene, nga wira, me te mohio tata;Ka taea e te Kaitirotiro Kaitirotiro (WDT), te kaitirotiro parauri-waho me te Whakahou-a-hiko me te hotaka Wire Debug (SWD) e rua titi me te atanga patuiro.Ko nga taputapu katoa he tika, he iti te kaha o nga oscillator o waho me roto.Ka taea te whakamahi i nga oscillators katoa hei puna mo te karaka punaha.Ka taea te whirihora motuhake i nga rohe karaka rereke kia rere i nga iarere rereke, ka taea te penapena hiko ma te whakahaere i ia peripheral ki tana auau karaka tino pai, me te pupuri i te auau CPU teitei i te whakaiti i te whakapau hiko.
