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

Nkọwa

NXP Semiconductors haziri LPC2468 microcontroller gburugburu 16-bit/32-bit ARM7TDMI-S CPU core nwere ezigbo ihe nbipu nke gụnyere ma JTAG na akara agbakwunyere.LPC2468 nwere 512 kB nke ebe nchekwa ọkụ na-agba ọsọ dị elu.Ebe nchekwa ọkụ a na-agụnye oghere ebe nchekwa obosara 128-bit pụrụ iche yana ihe nrụpụta ngwa ngwa nke na-enyere CPU aka ime usoro usoro site na ebe nchekwa flash na ọnụego elekere sistemụ 72 MHz kacha.Njirimara a dị naanị na LPC2000 ARM microcontroller ezinụlọ ngwaahịa.LPC2468 nwere ike mebe ma 32-bit ARM na 16-bit ntuziaka Thumb.Nkwado maka usoro nkuzi abụọ ahụ pụtara na ndị injinia nwere ike họrọ ịkwalite ngwa ha maka ịrụ ọrụ ma ọ bụ nha koodu na ọkwa nke obere oge.Mgbe isi na-eme ntuziaka na steeti Thumb ọ nwere ike belata nha koodu site na karịa 30 % yana naanị obere mfu na arụmọrụ ka ị na-eme ntuziaka na steeti ARM na-ebuli arụmọrụ bụ isi.Igwe njikwa LPC2468 dị mma maka ngwa nzikọrịta ozi ọtụtụ ebumnuche.Ọ na-agụnye 10/100 Ethernet Media Access Controller (MAC), ngwa ngwa ngwa USB / onye ọbịa / OTG na 4 kB nke njedebe RAM, UART anọ, ọwa abụọ Controller Area Network (CAN), SPI interface, abụọ Synchronous. Ọdụ ụgbọ mmiri Serial (SSP), oghere I2C atọ, yana interface I2S.Ịkwado nchikota nke nzikọrịta ozi serial bụ ihe ndị na-esonụ atụmatụ;ihe on-chip 4 MHz esịtidem oscillator ziri ezi, 98 kB nke ngụkọta RAM nke nwere 64 kB nke SRAM mpaghara, 16 kB SRAM maka Ethernet, 16 kB SRAM maka ebumnuche izugbe DMA, 2 kB nke batrị kwadoro SRAM, yana njikwa ebe nchekwa mpụga ( EMC).Atụmatụ ndị a na-eme ka ngwaọrụ a dabara nke ọma maka ụzọ nzikọrịta ozi na ndị ntụgharị protocol.Na-emeju ọtụtụ ndị na-ahụ maka nzikọrịta ozi serial, ike clocking dị iche iche, yana njirimara ebe nchekwa bụ oge 32-bit dị iche iche, 10-bit ADC emelitere, 10-bit DAC, nkeji PWM abụọ, nkwụchi mpụ anọ, yana ruo 160 ahịrị GPIO ngwa ngwa.LPC2468 na-ejikọ 64 nke pin GPIO na ngwaike dabere na Vector Interrupt Controller (VIC) nke pụtara na ntinye mpụta ndị a nwere ike iwepụta nkwụsịtụ na-ebute ihu.Atụmatụ ndị a niile na-eme ka LPC2468 dabara adaba maka njikwa ụlọ ọrụ na sistemu ahụike.
