Whakaahuatanga
Ko te LPC178x/7x he microcontroller ARM Cortex-M3 mo nga tono whakauru e hiahia ana ki te taumata teitei o te whakauru me te iti o te tohanga mana.Ko te ARM Cortex-M3 he reanga matua e whai ake nei e tuku ana i nga mahi pai ake i te ARM7 i te reiti karaka kotahi me etahi atu whakanikotanga o te punaha penei i nga ahuatanga patuiro hou me te taumata teitei ake o te whakauru poraka tautoko.Ko te ARM Cortex-M3 CPU e whakauru ana i te pipeline 3-waahanga me te hoahoanga Harvard me nga whakaakoranga a-rohe me nga pahi raraunga, me te toru o nga pahi he iti ake te mahi mo nga peripheral.Kei roto hoki i te ARM Cortex-M3 PTM he waeine prefetch o roto e tautoko ana i nga peka whakaaro.Ka taapirihia e te LPC178x/7x he kaiwhakatere mahara rama motuhake hei whakatutuki i nga mahi tino pai i te wa e mahia ana te waehere mai i te uira.Ko te LPC178x/7x e mahi ana ki runga ki te 120 MHz CPU auau.Ko te taapiri taapiri o te LPC178x/7x tae atu ki te 512 kB o te mahara o te kaupapa flash, tae atu ki te 96 kB o te mahara raraunga SRAM, tae atu ki te 4032 paita o te mahara raraunga EEPROM, te Kaiwhakahaere Mahara o waho (EMC), LCD (LPC178x anake), Ethernet. , Pūrere USB/Kaihautū/OTG, he pūmana DMA Kaupapa Whānui, e rima nga UART, e toru nga kaiwhakahaere SSP, e toru nga atanga I2C-pahi, he Atanga Whakawaehere Tapawhā, e wha nga kaitaima mahi whanui, e rua nga PWM kaupapa whaanui me nga putanga e ono mo ia me te kotahi motika mana PWM , he RTC mana iti-iti me te tuku pākahiko motuhake me te kaiwhakamahara takahanga, he matama kaitutei matapihi, he miihini tatauranga CRC, tae atu ki te 165 titi I/O kaupapa whanui, me etahi atu.Kei roto i nga taputapu tairitenga tetahi ADC moka-12 me te DAC 10-bit.Ko te pinout o te LPC178x/7x te tikanga kia pai ai te hototahi mahi titi ki te LPC24xx me te LPC23xx.
