LPC2468FBD208,551 IC MCU 16 / 32B 512KB FLSH 208LQFP

Ibisobanuro

NXP Semiconductor yateguye microcontroller ya LPC2468 hafi ya 16-bit / 32-bit ya ARM7TDMI-S CPU yibanze hamwe nigihe nyacyo cyo gukemura ibibazo birimo JTAG hamwe nibisobanuro byashyizwemo.LPC2468 ifite 512 kB ya-chip yihuta ya flash yibuka.Iyi flash yibuka ikubiyemo ububiko bwihariye bwa 128-bit yagutse yububiko hamwe nubwubatsi bwihuta butuma CPU ikora amabwiriza akurikirana kuva flash yibuka kuri 72 MHz ya sisitemu ntarengwa.Iyi mikorere iraboneka gusa kuri LPC2000 ARM microcontroller yumuryango wibicuruzwa.LPC2468 irashobora gukora byombi 32-bit ARM hamwe na 16-bit ya Thumb amabwiriza.Inkunga kubice bibiri byamasomo bivuze ko injeniyeri ashobora guhitamo guhitamo ibyifuzo byabo haba mubikorwa cyangwa ingano ya code kurwego rwo munsi.Iyo intangiriro ikora amabwiriza muri leta ya Thumb irashobora kugabanya ingano ya code kurenza 30% hamwe nigihombo gito gusa mubikorwa mugihe ikora amabwiriza muri leta ya ARM yerekana imikorere yibanze.LPC2468 microcontroller nibyiza kubikorwa byinshi byitumanaho.Harimo 10/100 Ethernet Media Access Controller (MAC), USB igikoresho cyihuta cya USB / Host / OTG Igenzura hamwe na 4 kB ya RAM ya nyuma, UARTs enye, imiyoboro ibiri ya Network Controller (CAN), imiyoboro ya SPI, Synchronous ebyiri Ibyambu bya Serial (SSP), Imigaragarire itatu ya I2C, hamwe na I2S.Gushyigikira iki cyegeranyo cyitumanaho ryitumanaho ni ibintu bikurikira bikurikira;kuri chip 4 MHz oscillator y'imbere, 98 kB ya RAM yose igizwe na 64 kB ya SRAM yaho, 16 kB SRAM kuri Ethernet, 16 kB SRAM kubwintego rusange DMA, 2 kB ya bateri ikoreshwa na SRAM, hamwe nububiko bwo hanze () EMC).Ibiranga bituma iki gikoresho gikwiranye ninzira yo gutumanaho hamwe na protocole ihindura.Kuzuza ibyiciro byinshi byitumanaho bigenzura, ubushobozi bwisaha butandukanye, hamwe nibikoresho byo kwibuka nibihe bitandukanye 32-biti, byatejwe imbere 10-biti ADC, 10-bit DAC, ibice bibiri bya PWM, ibyuma bine byo guhagarika, hamwe numurongo wa GPIO wihuta 160.LPC2468 ihuza 64 ya pin ya GPIO hamwe nibikoresho bishingiye kuri Vector Interrupt Controller (VIC) bivuze ko ibyo byinjira hanze bishobora kubyara intambamyi.Ibi byose biranga bituma LPC2468 ibereye cyane kugenzura inganda na sisitemu yubuvuzi.
