Whakaahuatanga
Te Atmel® |Ko SMART™ SAM D20 he raupapa o nga microcontrollers iti-hiko e whakamahi ana i te 32-bit ARM® Cortex® - M0+ pūtukatuka, mai i te 32- ki te 64-pin me te 256KB Flash me te 32KB o te SRAM.Ko nga taputapu SAM D20 e mahi ana i te auau teitei o te 48MHz ka eke 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 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 SAM D20 e whakarato ana i nga ahuatanga e whai ake nei: In-system programmable Flash, eight-channel Event System, programmable interrupt controller, ki runga ki te 52 programmable I/O pins, 32-bit real-time karaka me te maramataka, tae atu ki te waru 16-bit Matawā/Kaitatau (TC) .Ka taea te whirihora i te taima/kaitatau ki te whakaputa 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, ka taea nga TC kua kowhiria te whakaheke kia hanga he TC 32-bit.Ko te raupapa e whakarato ana kia ono nga waahanga Whakawhitiwhiti Rangarangi (SERCOM) ka taea te whirihora ki ia mahi hei USART, UART, SPI, I2C tae atu ki te 400kHz, tae atu ki te rua tekau nga hongere 350ksps 12-bit ADC me te taonga ka taea te whakarite me te taapiri me te whakahekenga. tautoko ake ki te 16-bit taumira, kotahi 10-bit 350ksps DAC, e rua whakatairite tairitenga ki te aratau matapihi, Peripheral Touch Controller tautoko ake ki te 256 pātene, rēreti, wira me te tata rongo;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.
