Whakaahuatanga
Ma te kaitirotiro VDD maramara, Maataki Maataki, me te oscillator karaka, ko nga taputapu C8051F020/1/2/3 he tino rongoa punaha-i-a-Chip.Ko nga taputapu tairitenga me nga taputapu matihiko katoa ka whakahohea/whakakorehia, ka whirihorahia e te firmware kaiwhakamahi.Ka taea te reprogrammed te mahara FLASH ahakoa i roto i te ara-a-waahanga, e whakarato ana i te rokiroki raraunga kore-kore, me te tuku hoki i nga whakahoutanga mara o te 8051 firmware.I runga i te poari JTAG debug circuitry ka taea e kore e pokanoa (kaore he rauemi i runga i te maramara), tere tonu, i roto i te iahiko patuiro ma te whakamahi i te hanga MCU i whakauruhia ki te tono whakamutunga.Ka tautokohia e tenei punaha patuiro te tirotiro me te whakarereketanga o te mahara me nga rehitatanga, te whakatakoto i nga waahi wehenga, nga waahi mataara, te hikoi kotahi, te oma me te whakamutu i nga whakahau.Ko nga taputapu tairitenga me nga taputapu mamati e tino mahi ana i te wa e patuiro ana ma te whakamahi JTAG.Ko ia MCU kua tohua mo te mahi 2.7 V-ki-3.6 V i runga i te awhe pāmahana ahumahi (-45° C ki +85° C).Ko te Port I/Os, /RST, me te JTAG titi he pai mo nga tohu whakauru ki te 5 V. Kei te waatea te C8051F020/2 i roto i te kete TQFP 100-pin (tirohia nga hoahoa poraka i te Whakaahua 1.1 me te Whakaahua 1.3).Kei te waatea te C8051F021/3 i roto i te kete TQFP 64-titi (tirohia nga hoahoa poraka i te Whakaahua 1.2 me te Whakaahua 1.4).
