Whakaahuatanga
Ka whakawhānuihia e te LPC122x te 32-bit ARM microcontroller continuum a NXP me te whai i te whānuitanga o nga tono ahumahi i roto i nga waahi o te wheketere me te miihini kaainga.Ma te whai hua mai i te huinga tohutohu ARM Cortex-M0 Thumb, ko te LPC122x he 50 % teitei ake te kiato waehere ka whakaritea ki te mokowhiti 8/16-bit noa e mahi ana i nga mahi angamaheni.Kei roto ano i te LPC122x tetahi whare pukapuka wehewehe-a-ROM mo Cortex-M0, he maha nga wa e tuku ana i nga mahi tatau o nga whare pukapuka-rorohiko, me te waa huringa tino whakatau me te whakaheke i te rahi o te waehere flash.Ko te kaha o te ARM Cortex-M0 ka awhina i te LPC122x ki te whakatutuki i te mana toharite iti mo nga tono rite.Ko te LPC122x e mahi ana i nga iarere CPU ki runga ki te 45 MHz. Ka whakaekea e ratou te maha o nga whiringa mahara flash, mai i te 32 kB ki te 128 kB.Ko te iti o te wharangi 512-paita te muru o te mahara flash he maha nga hua hoahoa, penei i te pai ake o te tauira EEPROM, te tautoko uta-uta mai i tetahi atanga rangatū me te ngawari o te hotaka i roto i te mara me te whakaiti i nga whakaritenga mo te parapara RAM.Ko te taapiri taapiri o te LPC122x kei roto he 10-bit ADC, e rua nga kaiwhakariterite me te kohanga urupare whakaputa, e rua nga UART, kotahi atanga SSP/SPI, kotahi atanga I2C-pahi me nga ahuatanga Tere-Mode Plus, he Mataima Matapihi Matapihi Matapihi, he kaiwhakahaere DMA, he miihini CRC, e wha nga kaima-a-whaa, he RTC 32-bit, he 1% oscillator o roto mo te whakatipu reiti baud, tae atu ki te 55 nga titi General Purpose I/O (GPIO).
