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

Inkcazo

IiSemiconductors ze-NXP zenze i-LPC2468 microcontroller ijikeleze i-16-bit/32-bit ARM7TDMI-S CPU engundoqo kunye nexesha lokwenene lodibaniso lwe-debug oluquka zombini i-JTAG kunye nomkhondo ofakwe ngaphakathi.I-LPC2468 ine-512 kB yememori ye-flash ekwi-chip enesantya esiphezulu.Le nkumbulo yeflash ibandakanya ujongano olukhethekileyo lwe-128-bit yememori ebanzi kunye nolwakhiwo lwe-accelerator eyenza ukuba i-CPU iphumeze imiyalelo elandelelanayo evela kwimemori edanyazayo kubuninzi besantya sewotshi ye-72 MHz.Eli nqaku lifumaneka kuphela kwi-LPC2000 ARM microcontroller usapho lweemveliso.I-LPC2468 inokuphumeza zombini i-32-bit ARM kunye ne-16-bit yemiyalelo ye-Thumb.Inkxaso yeeseti zemiyalelo emibini ithetha ukuba iinjineli zinokukhetha ukwandisa isicelo sabo nokuba yintsebenzo okanye ubungakanani bekhowudi kwinqanaba le-sub-routine.Xa undoqo uphumeza imiyalelo kwimeko ye-Thumb inokunciphisa ubungakanani bekhowudi ngaphezu kwe-30 % ngelahleko encinci kuphela ekusebenzeni ngelixa uphumeza imiyalelo kwimeko ye-ARM iphakamisa ukusebenza okungundoqo.I-LPC2468 microcontroller ilungele izicelo zonxibelelwano lweenjongo ezininzi.Idibanisa i-10/100 Ethernet Media Access Controller (MAC), i-USB egcwele i-Device / Host / OTG Controller ene-4 kB ye-RAM yokuphela, ii-UART ezine, iziteshi ezimbini ze-Control Area Network (CAN), i-SPI interface, ezimbini ze-Synchronous. Amazibuko othotho (SSP), ujongano lwe-I2C emithathu, kunye nojongano lwe-I2S.Ukuxhasa le ngqokelela yonxibelelwano olulandelelanayo ujongano ngala macandelo alandelayo;i-oscillator ye-on-chip ye-4 MHz yangaphakathi echanekileyo, i-98 kB ye-RAM iyonke equka i-64 kB ye-SRAM yendawo, i-16 kB SRAM ye-Ethernet, i-16 kB SRAM ngenjongo eqhelekileyo ye-DMA, i-2 kB ye-SRAM enikwe ibhetri, kunye noMlawuli weMemori yangaphandle ( EMC).Ezi mpawu zenza esi sixhobo sifaneleke ngokugqibeleleyo kumasango onxibelelwano kunye neziguquli zeprothokholi.Ukuzalisekisa abalawuli abaninzi bonxibelelwano lwe-serial, i-clocking clocking capabilities, kunye neempawu zememori zizinto ezahlukeneyo ze-32-bit timers, i-10-bit ye-ADC ephuculweyo, i-10-bit DAC, iiyunithi ezimbini ze-PWM, izikhonkwane ezine zokuphazamiseka kwangaphandle, kunye ne-160 imigca ye-GPIO ekhawulezayo.I-LPC2468 idibanisa i-64 yezikhonkwane ze-GPIO kwi-hardware esekelwe kwi-Vector Interrupt Controller (VIC) oko kuthetha ukuba ezi galelo zangaphandle ziyakwazi ukuvelisa iziphazamiso ze-edge-triggered.Zonke ezi mpawu zenza i-LPC2468 ilungele ngokukodwa ulawulo lwamashishini kunye neenkqubo zonyango.
