Ka on-chip VDD monitor, Watchdog Timer, le oscillator oache, lisebelisoa tsa C8051F020/1/2/3 ke litharollo tse ikemetseng tsa System-on-a-Chip.Lisebelisoa tsohle tsa analoge le tsa dijithale li nolofalitsoe / li holofalitsoe ebile li hlophisoa ke firmware ea mosebelisi.Memori ea FLASH e ka hlophisoa bocha esita le ka har'a potoloho, e fana ka polokelo ea data e sa fetoheng, hape e lumella ntlafatso ea tšimo ea firmware ea 8051.Ka holim'a board ea JTAG debug circuitry e lumella ho se kenelle (ha e sebelise lisebelisoa tsa on-chip), lebelo le felletseng, debugging in-circuit ho sebelisa MCU ea tlhahiso e kentsoeng ts'ebelisong ea ho qetela.Sistimi ena ea debug e ts'ehetsa tlhahlobo le ho fetoloa ha memori le lirejisete, ho beha libaka tsa phomolo, li-watchpoints, ho hata hang, ho matha le ho emisa litaelo.Lisebelisoa tsohle tsa analog le tsa dijithale li sebetsa ka botlalo ha li ntse li lokisa liphoso li sebelisa JTAG.MCU e 'ngoe le e' ngoe e hlalositsoe bakeng sa ts'ebetso ea 2.7 V-to-3.6 V ho feta mocheso oa indasteri (-45 ° C ho + 85 ° C).Li-Port I / Os, / RST, le li-pin tsa JTAG li mamella matšoao a ho kenya ho fihlela ho 5 V. C8051F020 / 2 e fumaneha ka har'a sephutheloana sa TQFP sa 100-pin (sheba li-block diagrams ho Setšoantšo sa 1.1 le Setšoantšo sa 1.3).C8051F021/3 e fumaneha ka har'a sephutheloana sa TQFP sa 64-pin (sheba li-block diagrams ho Setšoantšo sa 1.2 le Setšoantšo sa 1.4).
