Whakaahuatanga
Ko te LPC2388 microcontroller kei runga i te 16-bit/32-bit ARM7TDMI-S CPU me te wa-tūturu emulation 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.He pai te LPC2388 mo nga tono whakawhitiwhiti korero rangatū maha.Kei roto i te 10/100 Ethernet Media Access Controller (MAC), te taputapu USB / ope / OTG me te 4 kB o te mutunga o te RAM, e wha nga UART, e rua nga waahana CAN, he atanga SPI, e rua nga Tauranga Serial Tukutahi (SSP), e toru nga hononga I2C, he atanga I2S, me te Kaiwhakahaere Mahara o waho (EMC).Ko tenei whakakotahitanga o nga hononga whakawhitiwhiti rangatū kua honoa me te oscillator a-roto 4 MHz, SRAM o 64 kB, 16 kB SRAM mo Itarangi, 16 kB SRAM mo te USB me te whakamahi kaupapa whanui, me te 2 kB pākahiko SRAM kia tino pai tenei taputapu. e tika ana 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. tino pai mo te whakahaere ahumahi me nga punaha hauora.
