Whakaahuatanga
Ko te LPC435X_3X_2X_1X he microcontrollers ARM Cortex-M4 e hangai ana me te Wae Ira Maango (FPU) mo nga tono whakauru kei roto ko te ARM Cortex-M0 kaitukatuka, tae atu ki te 1 MB o te uira me te 136 kB o te maramara SRAM, 16 kB o te mahara EEPROM, e rua. nga kaiwhakahaere USB tere-tere, Itarangi, LCD, he kaiwhakahaere mahara o waho, he whaa SPI Flash Atanga (SPIFI) e tautoko ana i te mahi-i roto i te waahi, i nga taputapu whirihora matatau penei i te State Configurable Timer (SCTimer/PWM) me te Serial General Purpose Atanga I/O (SGPIO), me te maha o nga taputapu mamati me te tairitenga.Ko te LPC435X_3X_2X_1X e mahi ana i nga iarere CPU tae atu ki te 204 MHz.Ko te ARM Cortex-M4 he 32-bit matua e tuku ana i nga whakanikotanga o te punaha penei i te iti o te kohi hiko, te whakapai ake i nga ahuatanga patuiro, me te taumata teitei o te whakauru poraka tautoko.Ko te ARM Cortex-M4 CPU e whakauru ana i te pipeline 3-waahanga, ka whakamahi i te hoahoanga Harvard me nga whakaakoranga a-rohe me nga pahi raraunga me te toru o nga pahi mo nga peripheral, me te whakauru i tetahi waeine prefetch o roto e tautoko ana i te manga whakaaro.Ko te ARM Cortex-M4 e tautoko ana i te tukatuka tohu mamati huringa kotahi me nga tohutohu SIMD.He pūtukatuka māngi pūmārō kua tuituia ki roto i te matua.Ko te ARM Cortex-M0 coprocessor he tino kaha-kaha me te ngawari ki te whakamahi i te 32-bit matua, he waehere whakarunga- me te taputapu-hototahi ki te matua Cortex-M4.He mea pai mo te whakahaere i te mana whakahaere, te whakahaere peripheral ranei ki te whakaatea i te Cortex-M4 mo te tukatuka i te waa-tūturu.Ko te Cortex-M0 coprocessor e tuku ana ki te 204 MHz mahi me te huinga tohutohu ngawari me te whakaiti i te rahi o te waehere.I roto i te LPC43xx, ka whakatinanahia te Cortex-M0 coprocessor hardware multiply hei whakarea 32-hurihuri.
