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

Kev piav qhia

NXP Semiconductors tsim LPC2468 microcontroller nyob ib ncig ntawm 16-ntsis / 32-ntsis ARM7TDMI-S CPU core nrog lub sijhawm debug interfaces uas suav nrog ob qho tib si JTAG thiab embedded kab.LPC2468 muaj 512 kB ntawm on-chip high-speed flash nco.Lub cim xeeb flash no suav nrog qhov tshwj xeeb 128-ntsis lub cim xeeb dav dav thiab cov txheej txheem nrawm uas ua rau CPU ua cov lus qhia ua ntu zus los ntawm flash nco ntawm qhov siab tshaj 72 MHz system moos.Cov yam ntxwv no tsuas muaj nyob rau ntawm LPC2000 ARM microcontroller tsev neeg ntawm cov khoom.LPC2468 tuaj yeem ua tiav ob qho 32-ntsis ARM thiab 16-ntsis Thumb cov lus qhia.Kev them nyiaj yug rau ob qhov kev qhia ntawv txhais tau tias cov engineers tuaj yeem xaiv los ua kom zoo dua lawv daim ntawv thov rau kev ua tau zoo lossis cov lej loj ntawm qib sub-routine.Thaum cov tub ntxhais ua tiav cov lus qhia hauv Thumb xeev nws tuaj yeem txo cov lej loj los ntawm ntau dua 30% nrog tsuas yog poob me me hauv kev ua haujlwm thaum ua cov lus qhia hauv ARM lub xeev ua kom muaj txiaj ntsig zoo tshaj plaws.Lub LPC2468 microcontroller yog qhov zoo tagnrho rau kev sib txuas lus ntau lub hom phiaj.Nws suav nrog 10/100 Ethernet Media Access Controller (MAC), USB full-speed Device / Host / OTG Controller nrog 4 kB ntawm endpoint RAM, plaub UARTs, ob Controller Area Network (CAN) raws, ib qho SPI interface, ob Synchronous Serial Ports (SSP), peb I2C interfaces, thiab I2S interface.Txhawb qhov kev sau ntawm serial kev sib txuas lus interfaces yog cov nram qab no feature Cheebtsam;ib qho on-chip 4 MHz internal precision oscillator, 98 kB ntawm tag nrho RAM muaj 64 kB ntawm lub zos SRAM, 16 kB SRAM rau Ethernet, 16 kB SRAM rau dav dav DMA, 2 kB ntawm roj teeb powered SRAM, thiab ib tug sab nraud nco Controller ( EMC).Cov yam ntxwv no ua rau cov cuab yeej no zoo rau kev sib txuas lus rooj vag thiab kev hloov pauv raws tu qauv.Ua kom tiav cov kev sib txuas lus ntau yam, muaj peev xwm ua tau ntau yam, thiab lub cim xeeb muaj ntau yam 32-ntsis timers, kev txhim kho 10-ntsis ADC, 10-ntsis DAC, ob lub PWM units, plaub sab nraud cuam tshuam pins, thiab mus txog 160 ceev GPIO kab.Lub LPC2468 txuas 64 ntawm GPIO pins rau cov khoom siv kho vajtse raws li Vector Interrupt Controller (VIC) uas txhais tau tias cov khoom siv sab nraud tuaj yeem tsim cov kev cuam tshuam ntawm ntug.Tag nrho cov yam ntxwv no ua rau LPC2468 tshwj xeeb yog tsim rau kev tswj hwm kev lag luam thiab kev kho mob.
