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

Incazelo

Ama-Semiconductors e-NXP adizayine i-LPC2468 microcontroller eduze kwe-16-bit/32-bit ARM7TDM-S CPU core enokusebenzelana kokususa iphutha kwesikhathi sangempela okufaka kokubili i-JTAG nokulandelela okushumekiwe.I-LPC2468 ine-512 kB ye-on-chip high-speed flash memory.Le memori ye-flash ihlanganisa isixhumi esibonakalayo esikhethekile senkumbulo ebanzi engu-128-bit kanye nesakhiwo se-accelerator esivumela i-CPU ukuthi isebenzise imiyalo elandelanayo esuka kumemori ye-flash ngezinga eliphezulu lewashi lesistimu engu-72 MHz.Lesi sici sitholakala kuphela kumndeni wemikhiqizo ye-LPC2000 ARM microcontroller.I-LPC2468 ingakwazi ukusebenzisa kokubili i-32-bit ARM kanye nemiyalelo ye-Thumb engu-16-bit.Ukusekelwa kwamasethi amabili wemiyalo kusho ukuthi onjiniyela bangakhetha ukuthuthukisa isicelo sabo sokusebenza noma usayizi wekhodi ezingeni le-sub-routine.Uma okubalulekile kusebenzisa imiyalelo kusimo Sesithupha kunganciphisa usayizi wekhodi ngaphezu kuka-30 % ngokulahlekelwa okuncane kuphela ekusebenzeni kuyilapho ukusebenzisa imiyalelo kusimo se-ARM kukhulisa ukusebenza okubalulekile.Isilawuli esincane se-LPC2468 silungele izinhlelo zokusebenza zokuxhumana ezinezinjongo eziningi.Ihlanganisa i-10/100 Ethernet Media Access Controller (MAC), Isilawuli se-USB esigcwele isivinini Sedivayisi/Isingethe/OTG esine-4 kB ye-endpoint RAM, ama-UART amane, iziteshi ezimbili zeController Area Network (CAN), isixhumi esibonakalayo se-SPI, ezimbili Ezivumelanayo. I-Serial Ports (SSP), izixhumanisi ezintathu ze-I2C, kanye nesixhumi esibonakalayo se-I2S.Ukusekela leli qoqo lezixhumi ezibonakalayo zezokuxhumana yizici ezilandelayo;i-oscillator enembile engu-4 MHz yangaphakathi, 98 kB yenani le-RAM ehlanganisa u-64 kB we-SRAM yasendaweni, 16 kB SRAM ye-Ethernet, 16 kB SRAM ngenjongo evamile ye-DMA, 2 kB ye-SRAM esebenza ngebhethri, kanye Nesilawuli Senkumbulo Yangaphandle ( EMC).Lezi zici zenza le divayisi ifaneleke ngokufanelekile kumasango okuxhumana neziguquli zephrothokholi.Ukugcwalisa izilawuli eziningi zokuxhumana ze-serial, amandla ewashi ahlukahlukene, kanye nezici zenkumbulo izibali-sikhathi ezihlukene ze-32-bit, i-10-bit ADC ethuthukisiwe, i-10-bit DAC, amayunithi amabili e-PWM, izikhonkwane ezine eziphazamisayo zangaphandle, nemigqa efika ku-160 ye-GPIO esheshayo.I-LPC2468 ixhuma amaphinikhodi angu-64 e-GPIO ku-hardware esekelwe ku-Vector Interrupt Controller (VIC) okusho ukuthi lokhu okokufaka kwangaphandle kungadala ukuphazamiseka okucushwe emaphethelweni.Zonke lezi zici zenza i-LPC2468 ifaneleke kakhulu ukulawula izimboni nezinhlelo zezokwelapha.
