Whakaahuatanga
Ko nga microcontrollers LPC2377/78 kei runga i te PTM 16-bit/32-bit ARM7TDMI-S me te whai i te wa-tuturu e whakakotahi ana i te microcontroller me te 512 kB o te mahara kohiko tere-tere.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 mahi tino nui i roto i nga mahinga ratonga haukoti me te DSP algorithms, ka piki ake te mahinga ki te 30% i runga i te aratau Thumb.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.Ko te LPC2377/78 he pai mo nga tono korero rangatū maha.Kei roto i te 10/100 Ethernet Media Access Controller (MAC), USB taputapu tere katoa me te 4 kB o te mutunga o te RAM (LPC2378 anake), e wha nga UART, e rua nga waahana CAN (LPC2378 anake), he atanga SPI, e rua nga Tauranga Serial Tukutahi (SSP). ), e toru nga atanga I2C-pahi, he atanga I 2S-pahi, me tetahi Kaiwhakahaere Mahara o waho (EMC).Ko tenei whakakotahitanga o nga atanga korero rangatū kua honoa ki te maramara 4 MHz oscillator o roto, SRAM o 32 kB, 16 kB SRAM mo Itarangi, 8 kB SRAM mo te USB me te whakamahi kaupapa whanui, me te 2 kB pākahiko SRAM kia pai tenei taputapu mo nga kuaha korero me nga kaitahuri kawa.He momo matawā moka-32, he ADC moka-10 kua pai ake, he DAC moka-10, he wae PWM, he wae mana CAN, tae atu ki te 104 nga raina GPIO tere tae atu ki te 50 tapa me te wha nga taumata o nga titi haukoti o waho e hangai ana i enei microcontrollers. he pai mo te whakahaere ahumahi me nga punaha hauora.
