Fa'amatalaga
O le AT89S52 o se masini fa'aletonu, maualuga le CMOS 8-bit microcontroller ma le 8K bytes o le fa'aogaina o le Flash e mafai ona fa'aogaina.O lo'o gaosia le masini e fa'aaoga ai le tekonolosi fa'amanino e le fa'amalieina maualuga a Atmel ma e fetaui lelei ma le fa'atonuga fa'atonu 80C51 ma le pinout.Ole on-chip Flash e mafai ai ona toe fa'apolokalameina le manatua o le polokalame i totonu o le polokalama po'o se polokalame e manatua ai mea e le masani ai.E ala i le tuʻufaʻatasia o se PPU 8-bit faʻapitoa faʻatasi ma le Flash e mafai ona faʻaogaina i totonu o se masini monolithic, o le Atmel AT89S52 o se microcontroller mamana lea e maua ai se fofo sili ona fetuutuunai ma taugofie i le tele o faʻatonuga faʻapipiʻiina.O le AT89S52 o loʻo tuʻuina atu ai tulaga faʻapitoa nei: 8K bytes o le Flash, 256 bytes o le RAM, 32 I/O laina, Watchdog timer, lua faʻamatalaga faʻamatalaga, tolu 16-bit timer/counters, se ono-vector lua-level interrupt architecture, a uafu faakomepiuta atoa, oscillator i luga o chip, ma le uati circuitry.E le gata i lea, o le AT89S52 ua mamanuina ma le faʻaogaina o le faʻaogaina i lalo i le leai o taimi ma lagolagoina ni polokalame se lua e mafai ona faʻasaoina le mana.O le Idle Mode e taofia ai le PPU a'o fa'ataga le RAM, timer/counters, laina telefoni, ma fa'alavelave fa'alavelave e fa'aauau pea ona galue.O le Power-down mode e fa'asaoina ai mea o lo'o i totonu o le RAM ae fa'amalo ai le oscillator, fa'agata uma isi galuega pu'e se'ia o'o i le isi fa'alavelave po'o le toe setiina o meafaigaluega.
