Whakaahuatanga
Ko te LPC2364/65/66/67/68 microcontrollers kei runga i te 16-bit/32-bit ARM7TDMI-S CPU me te wa-tūturu emulation e whakakotahi ana i te microcontroller ki te 512 kB o te mahara kohiko tere-tere kua mau.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 LPC2364/65/66/67/68 he pai mo nga tono korero rangatū kaupapa maha.Ka whakauruhia he 10/100 Ethernet Media Access Controller (MAC), USB taputapu tere katoa me te 4 kB o te mutunga o te RAM (LPC2364/66/68 anake), e wha nga UART, e rua nga waahana CAN (LPC2364/66/68 anake), he SPI atanga, e rua nga Tauranga Rangatū Tukutahi (SSP), e toru nga hononga I 2C-pahi, me tetahi atanga I2S-pahi.Ko tenei whakakotahitanga o nga hononga whakawhitiwhiti rangatū kua honoa me te oscillator a-roto 4 MHz, SRAM tae atu ki te 32 kB, 16 kB SRAM mo Itarangi, 8 kB SRAM mo te USB me te whakamahi kaupapa whanui, me te 2 kB pākahiko SRAM hanga enei taputapu. tino pai mo nga kuaha korero me nga kaitahuri kawa.Moka-32 momo taima, he moka-10 ADC kua pai ake, moka-10 DAC, he wae PWM kotahi, he wae mana CAN (LPC2364/66/68 anake), tae atu ki te 70 nga raina GPIO tere tae atu ki te 12 mata, taumata tairongo ranei Ko nga titi haukoti o waho ka tino pai enei microcontrollers mo te whakahaere ahumahi me nga punaha rongoa.
