♠ I-Arm®-Cortex®-M4 32b MCU+FPU, 125 DMIPS, 1MB Flash, 256KB RAM, USB OTG FS, 17 TIMs, 1 ADC, 17 comm.izindawo zokuhlangana
Amadivayisi we-STM32F412XE/G asekelwe ekusebenzeni okuphezulu kwe-Arm® Cortex® -M4 32-bitI-RISC core esebenza ngemvamisa efika ku-100 MHz.Izici zabo eziyinhloko ze-Cortex®-M4 aIyunithi yephoyinti elintantayo (i-FPU) ukunemba okukodwa okusekela yonke imiyalelo ye-Arm yokunemba okukodwa yokucubungula idatha nezinhlobo zedatha.Iphinde isebenzise isethi egcwele yemiyalelo ye-DSP kanyeiyunithi yokuvikela inkumbulo (MPU) ethuthukisa ukuphepha kohlelo lokusebenza.
Amadivayisi we-STM32F412XE/G awomugqa womkhiqizo we-STM32 Dynamic Efficiency™ (noimikhiqizo ehlanganisa ukusebenza kahle kwamandla, ukusebenza nokuhlanganiswa) kuyilapho wengeza okushaisici esisha esibizwa nge-Batch Acquisition Mode (BAM) esivumela amandla engeziweukusetshenziswa ukonga ngesikhathi sokuqoqwa kwedatha.
Imishini ye-STM32F412XE/G ihlanganisa izinkumbulo ezishumekwe ngesivinini esiphezulu (kufika ku-1 Mbyte yeImemori ye-Flash, 256 Kbytes we-SRAM), kanye nohlu olubanzi lwama-I/O athuthukisiwe kanyeamabhasi axhunywe kumabhasi amabili e-APB, amabhasi amathathu e-AHB kanye nebhasi le-AHB elingu-32-biti-matrix.
Wonke amadivayisi anikela nge-12-bit ADC eyodwa, i-RTC enamandla aphansi, izibali-sikhathi eziyi-16-bit ezihloselwe jikelele eziyishumi nambili,izibali sikhathi ze-PWM ezimbili zokulawula imoto nezibali-sikhathi ezimbili zenhloso evamile engu-32-bit.
Ziphinde zibe nezindawo zokuxhumana ezijwayelekile nezithuthukile:
