Txhim kho FPGA PCB Board Tsim
Paub meej
2 Cov yam ntxwv ntawm cov peev txheej
2.1 Lub zog muaj zog:
[1] Txais USB_OTG, USB_UART thiab EXT_IN peb txoj kev siv hluav taws xob;
[2] Cov khoom siv hluav taws xob digital: Cov khoom siv hluav taws xob digital yog 3.3V, thiab cov khoom siv hluav taws xob zoo BUCK yog siv los muab lub zog rau ARM / FPGA / SDRAM, thiab lwm yam;
[3] FPGA core yog powered los ntawm 1.2V, thiab kuj siv ib tug high-efficiency BUCK Circuit Court;
[4] FPGA PLL muaj ntau cov analog circuits, txhawm rau ua kom muaj kev ua tau zoo ntawm PLL, peb siv LDO los muab lub zog analog rau PLL;
[5] STM32F767IG muab kev ywj pheej analog voltage siv los muab qhov siv hluav taws xob siv rau ntawm-chip ADC / DAC;
[6] Muab kev saib xyuas hluav taws xob thiab ntsuas ntsuas;
2.2 ARM nta:
[1] Kev ua tau zoo STM32F767IG nrog lub ntsiab zaus ntawm 216M;
[2] 14 kev ua haujlwm siab I / O nthuav dav;
[3] Multiplexing nrog I / O, suav nrog ARM built-in SPI / I2C / UART / TIMER / ADC thiab lwm yam haujlwm;
[4] suav nrog 100M Ethernet, kev kub ceev USB-OTG interface thiab USB rau UART muaj nuj nqi rau kev debugging;
[5] suav nrog 32M SDRAM, TF daim npav interface, USB-OTG interface (tuaj yeem txuas rau U disk);
[6] 6P FPC debugging interface, tus qauv adapter hloov mus rau qhov dav 20p interface;
[7] Siv 16-ntsis kev sib txuas lus tsheb npav;
2.3 FPGA Nta:
[1] Altera's plaub-tiam Cyclone series FPGA EP4CE15F23C8N yog siv;
[2] Txog 230 kev ua haujlwm siab I / O nthuav dav;
[3] FPGA nthuav tawm dual-chip SRAM nrog lub peev xwm ntawm 512KB;
[4] Configuration mode: txhawb JTAG, AS, PS hom;
[5] Txhawb nqa FPGA los ntawm ARM teeb tsa;AS PS muaj nuj nqi yuav tsum tau xaiv los ntawm jumpers;
[6] Siv 16-ntsis kev sib txuas lus tsheb npav;
[7] FPGA debug chaw nres nkoj: FPGA JTAG chaw nres nkoj;
2.4 Lwm yam nta:
[1] USB ntawm iCore4 muaj peb hom kev ua haujlwm: DEVICE hom, hom HOST thiab OTG hom;
[2] Hom Ethernet interface yog 100M puv duplex;
[3] Lub hwj huam mov hom tuaj yeem xaiv tau los ntawm jumper, USB interface yog siv ncaj qha, lossis los ntawm tus pin header (5V fais fab mov);
[4] Ob lub khawm ywj pheej yog tswj los ntawm ARM thiab FPGA feem;
[5] Ob lub teeb LED ntawm iCore4 heterogeneous dual-core industrial tswj board muaj peb xim: liab, ntsuab thiab xiav, uas yog tswj los ntawm ARM thiab FPGA feem;
[6] Txais 32.768K passive siv lead ua los muab RTC moos real-time rau lub kaw lus;
