Whakaahuatanga
Ko te LPC3220/30/40/50 whakaurunga microcontrollers i hangaia mo te iti o te mana, nga tono mahi teitei.I tutuki a NXP i a raatau whainga mahi ma te whakamahi i te tukanga nanometer 90 ki te whakatinana i te ARM926EJ-S CPU matua me te kaitukatuka tahi-tukatuka maanu vector me te huinga nui o nga peripheral paerewa tae atu ki te USB On-The-Go.Ko te LPC3220/30/40/50 e mahi ana i nga iarere CPU ki runga ki te 266 MHz.Ko te whakatinanatanga NXP e whakamahi ana i te ARM926EJ-S CPU matua me te hoahoanga Harvard, te 5-waahi paipa, me te Waenga Whakahaere Mahara (MMU).Ka whakaratohia e te MMU nga kaha mahara mariko e hiahiatia ana hei tautoko i nga tono maha-hotaka o nga punaha whakahaere hou.Kei te ARM926EJ-S ano he huinga taputapu o nga toronga tohutohu DSP, kei roto ko nga mahinga MAC huringa kotahi, me te Jazelle Java Byte-code execution taketake.Ko te whakatinanatanga NXP he keteroki tohutohu 32 kB me te keteroki raraunga 32 kB.Mo te iti o te kohi hiko, ka whai hua te LPC3220/30/40/50 i te whanaketanga hangarau matatau a NXP ki te arotau i te mana o roto me te whakamahi i nga whakanikonikotanga hoahoanga whakahaere rorohiko hei arotau i te whakahaerenga hiko i runga i te tono.Kei roto hoki i te LPC3220/30/40/50 te 256 kB o te RAM static on-chip, he atanga flash NAND, he Ethernet MAC, he kaiwhakahaere LCD e tautoko ana i nga panui STN me TFT, me tetahi atanga pahi waho e tautoko ana i te SDR me te DDR SDRAM hei me nga taputapu pateko.I tua atu, kei roto i te LPC3220 / 30/40/50 he USB 2.0 atanga tere-tere, e whitu nga UART, e rua nga hononga I2C-pahi, e rua nga tauranga SPI / SSP, e rua nga hononga I2S-pahi, e rua nga PWM putanga kotahi, he PWM mana motika. , e ono nga taima kaupapa whanui me nga whakaurunga hopu me te whakatairite i nga putanga, he atanga Mamati Haumaru (SD), me te 10-bit Analog-to-Digital Converter (ADC) me te kowhiringa mohio mata pa.
