Whakaahuatanga
Ko te LPC546xx he whanau o nga microcontrollers ARM Cortex-M4 mo nga tono whakauru e whakaatu ana i te huinga taapiri taonga me te iti rawa o te kohi hiko me te whakarei ake i nga ahuatanga patuiro.Ko te ARM Cortex-M4 he 32-bit matua e tuku ana i nga whakanikotanga o te punaha penei i te iti o te kohi hiko, te whakapai ake i nga ahuatanga patuiro, me te taumata teitei o te whakauru poraka tautoko.Ko te ARM Cortex-M4 CPU e whakauru ana i te pipeline 3-waahanga, ka whakamahi i te hoahoanga Harvard me nga whakaakoranga a-rohe me nga pahi raraunga me te toru o nga pahi mo nga peripheral, me te whakauru i tetahi waeine prefetch o roto e tautoko ana i te manga whakaaro.Ko te ARM Cortex-M4 e tautoko ana i te tukatuka tohu mamati huringa kotahi me nga tohutohu SIMD.He pūtukatuka māngi pūmārō kua tuituia ki roto i te matua.Kei roto i te whanau LPC546xx tae atu ki te 512 KB o te uira, 200 KB o runga maramara SRAM, tae atu ki te 16 kB o te mahara EEPROM, he whaa SPI Flash Atanga (SPIFI) mo te whakawhänui i te mahara o te kaupapa, kotahi te tere-tere me te kotahi USB tere-katoa. te kaihautu me te kaiwhakahaere taputapu, Ethernet AVB, LCD kaiwhakahaere, Atanga Kaari Maamaa, SD / MMC, CAN FD, he Kaiwhakahaere Mahara o waho (EMC), he punaha DMIC me te atanga hopuoro PDM me te I2S, e rima nga waahi-whanui, SCTimer / PWM, Matawā RTC/whakaoho, Matawā Reiti-Maha (MRT), he Matama Kaitutei Matapihi (WWDT), tekau maataki korero rangatū ngawari (USART, SPI, I2S, atanga I2C), Haurangi Hash Haumaru (SHA), 12-bit 5.0 Msamples/ hekona ADC, me te pūoko pāmahana.
