♠ AT91SAM ARM-based Flash MCU
I-SAM7S ye-Atmel luluhlu lwe-pincount ephantsi ye-Flash microcontrollers esekwe kwiprosesa ye-ARM ye-32-bit ye-RISC. Ibonisa iFlash enesantya esiphezulu kunye ne-SRAM, iseti enkulu yeeperipherals, kubandakanya isixhobo se-USB 2.0 (ngaphandle kwesixhoboSAM7S32 kunye ne-SAM7S16), kunye nesethi epheleleyo yemisebenzi yenkqubo yokunciphisa inani lamacandelo angaphandle.
Isixhobo siyindlela efanelekileyo yokufuduka kubasebenzisi be-8-bit microcontroller abafuna ukusebenza okongeziweyo kunyeinkumbulo eyandisiweyo.Imemori yeFlash elungisiweyo inokucwangciswa ngaphakathi kwinkqubo ngeJTAG-ICE ujongano okanye ngokujongana nojongano olunxuseneyokwiprogram yemveliso phambi kokunyuka. Amasuntswana okutshixa okwakhelwe ngaphakathi kunye nentwana yokhuseleko ikhusela i-firmware ekubhaleni ngaphezulu ngempazamo kwaye igcina imfihlo yayo.
Umlawuli wenkqubo ye-SAM7S Series uquka umlawuli wokusetha kwakhona okwazi ukulawula ukulandelelana kwamandla ngokulandelelanai-microcontroller kunye nenkqubo epheleleyo. Ukusebenza kwesixhobo esichanekileyo kunokujongwa yi-brownout eyakhelwe-ngaphakathii-detector kunye ne-watchdog eqhuba i-oscillator ye-RC edibeneyo.
I-SAM7S Series zi-microcontrollers zenjongo jikelele. Izibuko zabo ezidityanisiweyo zeSixhobo se-USB zibenza zibe zizixhobo ezifanelekileyokwiiaplikeshini zeperipheral ezifuna uqhagamshelo kwiPC okanye kwiselfowuni.
