Whakaahuatanga
Ko te LPC15xx he microcontrollers ARM Cortex-M3 mo nga tono whakauru e whakaatu ana i te huinga taapiri nui me te iti o te whakapau hiko.Ko te ARM Cortex-M3 he kaupapa whakatipuranga e whai ake nei e tuku ana i nga whakanikonikotanga o te punaha penei i nga ahuatanga patuiro whakarei me te taumata teitei ake o te whakauru poraka tautoko.Ko te LPC15xx e mahi ana i nga iarere CPU tae atu ki te 72 MHz.Ko te ARM Cortex-M3 CPU e whakauru ana i te pipeline 3-waahi me te whakamahi i te hoahoanga Harvard me nga tohutohu a-rohe me nga pahi raraunga me te toru o nga pahi mo nga taputapu.Kei roto hoki i te ARM Cortex-M3 PTM he waeine prefetch o roto e tautoko ana i te pekanga whakaaro.Kei roto i te LPC15xx te 256 kB o te mahara flash, 32 kB o ROM, te 4 kB EEPROM, me te 36 kB o SRAM.Kei roto i te taputapu taapiri tetahi taputapu USB 2.0 tere-katoa, e rua nga atanga SPI, e toru nga USART, kotahi te atanga Tere-Mode Plus I2C-pahihiko, kotahi te C_CAN module, PWM/timer subsystem me te wha ka taea te whirihora, he maha nga kaupapa a State Configurable Timers (SCTimer/ PWM) me te whakauru i mua i te waahanga tukatuka, he waahanga karaka-waahi me te tuku hiko motuhake me te oscillator whakatapua, e rua nga hongere 12/12-bit, 2 Msamples/s ADCs, kotahi 12-bit, 500 kSamples/s DAC, e wha nga whakatairite ngaohiko me te tohutoro ngaohiko a-roto, me te pūoko pāmahana.Ka taea e te miihini DMA te mahi i te nuinga o nga taputapu.
