AT90CAN128-16AU IC MCU 8BIT 128KB FLASH 64TQFP

Ibisobanuro

AT90CAN32 / 64/128 ni microcontroller ifite ingufu nkeya CMOS 8-bito ishingiye kuri AVR yazamuye ubwubatsi bwa RISC.Mugukurikiza amabwiriza akomeye mugihe cyisaha imwe, AT90CAN32 / 64/128 igera kubisubizo byegereye MIPS 1 kuri MHz ituma uwashizeho sisitemu yogukoresha ingufu hamwe numuvuduko wo gutunganya.AVR yibanze ihuza amabwiriza akungahaye hamwe na 32 rusange yibikorwa byakazi.Ibitabo byose uko ari 32 byahujwe na Arithmetic Logic Unit (ALU), bituma ibitabo bibiri byigenga bigerwaho mumabwiriza amwe akorerwa mugihe cyisaha imwe.Ubwubatsi bwavuyemo ni code ikora neza mugihe ugera kubisubizo byikubye inshuro icumi kurenza microcontrollers isanzwe ya CISC.AT90CAN32 / 64/128 itanga ibintu bikurikira: 32K / 64K / 128K bytes ya In-Sisitemu Programmable Flash ifite Gusoma-Mugihe-Kwandika ubushobozi, 1K / 2K / 4K bytes EEPROM, 2K / 4K / 4K bytes SRAM, 53 intego rusange Imirongo ya I / O, 32 rusange yibikorwa byakazi, umugenzuzi wa CAN, Igihe Cyukuri (RTC), Ibihe bine byoroshye bya Timer / Counters ugereranije nuburyo bwo kugereranya na PWM, 2 USARTs, byte yerekanwe Imirongo ibiri ya Serial Interface, umuyoboro wa 8 -bit ADC hamwe nuburyo butandukanye bwo kwinjiza ibyiciro hamwe ninyungu zishobora gutegurwa, igihe cyogukurikirana porogaramu hamwe na Oscillator Imbere, icyambu cya SPI, icyambu cya IEEE.1149.1 yujuje ibizamini bya JTAG, ikoreshwa kandi mukugera kuri sisitemu ya On-chip Debug na programming hamwe na software eshanu zatoranijwe zishobora kuzigama ingufu.Uburyo bwa Idle buhagarika CPU mugihe yemerera SRAM, Timer / Counters, ibyambu bya SPI / CAN hamwe na sisitemu yo guhagarika gukora.Uburyo bwa Power-down bubika ibyiyandikishije ariko bigahagarika Oscillator, bigahagarika indi mirimo yose ya chip kugeza igihe ubutaha buzahagarara cyangwa gusubiramo ibyuma.Muburyo bwo kuzigama imbaraga, ingengabihe idahwitse ikomeza gukora, yemerera uyikoresha kugumana igihe cyagenwe mugihe igikoresho gisigaye gisinziriye.Uburyo bwo kugabanya urusaku rwa ADC bihagarika CPU hamwe na moderi zose za I / O usibye Timer Asynchronous Timer na ADC, kugirango ugabanye urusaku rwo guhinduranya mugihe cya ADC ihinduka.Muburyo bwa standby, Crystal / Resonator Oscillator ikora mugihe igikoresho gisigaye gisinziriye.Ibi bituma gutangira byihuse bihujwe no gukoresha ingufu nke.Igikoresho cyakozwe hifashishijwe tekinoroji yo kwibuka cyane ya Atmel.Onchip ISP Flash ituma porogaramu yibuka ya porogaramu isubirwamo porogaramu muri sisitemu binyuze muri interineti ya SPI, hamwe na porogaramu isanzwe yo kwibuka idafite ingufu, cyangwa na porogaramu ya On-chip Boot ikorera kuri AVR yibanze.Porogaramu ya boot irashobora gukoresha interineti iyariyo yose kugirango ikuremo porogaramu muri porogaramu ya Flash yibuka.Porogaramu mu gice cya Boot Flash izakomeza gukora mugihe igice cya Flash Flash cyavuguruwe, gitanga ukuri Gusoma-Mugihe-Kwandika.
