Whakaahuatanga
Ko te LPC2141/42/44/46/48 microcontrollers kei runga i te 16-bit/32-bit ARM7TDMI-S PTM me te whai i te wa-tuturu me te tautoko tohu whakauru, e whakakotahi ana i te microcontroller me te mahara kohiko tere tere mai i te 32. kB ki te 512 kB.Ma te atanga mahara 128-bit whanui me te hoahoanga whakaterenga ahurei ka taea te mahi waehere moka-32 i te reiti karaka teitei.Mo nga tono rahinga waehere tino nui, ko te aratau 16-bit Thumb rereke ka whakaiti i te waehere neke atu i te 30 % me te iti o te whiunga mahi.Na te iti o te rahi me te iti o te kohi hiko, he pai te LPC2141/42/44/46/48 mo nga tono he mea nui te miniaturization, penei i te mana uru me te waahi-hoko.Ko nga hononga whakawhitiwhiti rangatū mai i te USB 2.0 taputapu tere-katoa, UART maha, SPI, SSP ki te I2C-pahi me te SRAM i runga i te maramara o te 8 kB ki te 40 kB, ka tino pai enei taputapu mo nga huarahi whakawhiti korero me nga kaitahuri kawa, ngawari. pouwhanga, reo āhukahuka me te iti atahanga mutunga, whakarato e rua rahi parepare me te mana tukatuka tiketike.Moka-32 matawā, kotahi, rua ranei 10-bit ADC(s), 10-bit DAC, PWM hongere me te 45 nga raina GPIO tere tae atu ki te iwa nga taha, te taumata tairongo ranei nga titi haukoti o waho e pai ana enei microcontrollers mo te whakahaere ahumahi me nga punaha hauora. .
