♠ AT91SAM ARM-based Flash MCU
I-SAM7S ye-Atmel iwuchungechunge lwama-Flash microcontrollers aphansi we-pincount asekelwe ku-32-bit ARM RISC processor.Ifaka i-Flash enesivinini esikhulu kanye ne-SRAM, isethi enkulu yama-peripherals, okuhlanganisa idivayisi ye-USB 2.0 (ngaphandle kwe-SAM7S32 kanye ne-SAM7S16), kanye nesethi ephelele yemisebenzi yesistimu enciphisa inani lezingxenye zangaphandle.
Idivayisi iyindlela ekahle yokuthutha yabasebenzisi be-8-bit microcontroller abafuna ukusebenza okwengeziwe kanyeinkumbulo enwetshiwe.Imemori ye-Flash eshumekiwe ingahlelwa ohlelweni ngesixhumi esibonakalayo se-JTAG-ICE noma ngesixhumi esibonakalayo esihambisanayokumhleli wokukhiqiza ngaphambi kokukhwezwa.Izingcezu zokukhiya ezakhelwe ngaphakathi kanye nentwana yokuvikeleka ivikela i-firmware ekubhaleni phansi ngephutha futhi igcina ubumfihlo bayo.
Isilawuli sesistimu ye-SAM7S Series sihlanganisa isilawuli sokusetha kabusha esikwazi ukuphatha ukulandelana kwamandla okukhanyisai-microcontroller kanye nesistimu ephelele.Ukusebenza kwedivayisi okulungile kungagadwa i-brownout eyakhelwe ngaphakathiumtshina kanye nenja yokubuka egijima ku-oscillator ye-RC ehlanganisiwe.
Uchungechunge lwe-SAM7S lungama-microcontrollers anenhloso ejwayelekile.Imbobo yabo ehlanganisiwe Yedivayisi ye-USB ibenza babe ngamadivayisi afanelekilengezinhlelo zokusebenza eziseduze ezidinga ukuxhumana ne-PC noma iselula.Iphuzu lentengo elinolaka kanye nezinga eliphezulu leukuhlanganiswa kucindezela ububanzi bokusebenzisa kwabo emakethe yabathengi engabizi kakhulu, enevolumu ephezulu.
