ATXMEGA256A3U-MH IC MCU 8/16BIT 256KB FLASH 64QFN

Tsanangudzo

Iyo Atmel AVR XMEGA imhuri ine simba rakaderera, kuita kwepamusoro, uye peripheral yakapfuma 8/16-bit microcontrollers yakavakirwa paAVR yakakwidziridzwa RISC dhizaini.Nekuita mirairo mukutenderera kwewachi imwe chete, iyo AVR XMEGA mudziyo unowana kuburikidza neCPU inosvika miriyoni yemirairo pasekondi (MIPS) pa megahertz, ichibvumira sisitimu yedhizaini kukwidziridza mashandisiro emagetsi nekumhanyisa kumhanya.Iyo AVR CPU inosanganisa yakapfuma kuraira kwakaiswa ne32 general chinangwa kushanda marejista.Ese marejista makumi matatu nembiri akabatana zvakananga kune arithmetic logic unit (ALU), achibvumira marejista maviri akazvimirira kuti awanikwe mukuraira kumwe chete, kunoitwa muwachi imwe chete.Iyo dhizaini yekuvaka inonyanya kushanda nekodhi uchiwana kuburikidza nekupfuura kakawanda nekukurumidza kupfuura yakajairwa single-accumulator kana CISC based microcontrollers.Iyo AVR XMEGA A3U zvishandiso zvinopa anotevera maficha: mu-system programmable flash ine kuverenga-panguva yekunyora kugona;mukati EEPROM uye SRAM;mana-channel DMA controller, masere-channel chiitiko system uye programmable multilevel interrupt controller, 50 general chinangwa I/O mitsara, 16-bit real-time counter (RTC);zvinomwe zvinoshanduka, 16-bit timer/counters ane enzanisa uye PWM chiteshi;nomwe UARTs;maviri-waya serial interfaces (TWIs);imwe yakazara yekumhanya USB 2.0 interface;matatu serial peripheral interfaces (SPIs);AES uye DES cryptographic injini;maviri 16-channel, 12-bit ADCs ane programmable kuwana;imwe 2-chiteshi 12-bit DAC;ina analog compators (ACs) ine hwindo mode;programmable watchdog timer ine yakaparadzana yemukati oscillator;akarurama emukati oscillators ane PLL uye prescaler;uye programmable brown-out kuona.Iyo purogiramu uye debug interface (PDI), inokurumidza, mbiri-pini interface yekuronga uye kugadzirisa, iripo.Zvishandiso zvakare zvine IEEE std.1149.1 inoenderana neJTAG interface, uye izvi zvinogona zvakare kushandiswa kumiganhu scan, pa-chip debug uye kuronga.
