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

Tlhaloso

Li-Semiconductors tsa NXP li thehile microcontroller ea LPC2468 ho potoloha 16-bit/32-bit ARM7TDM-S CPU mantlha e nang le likhokahano tsa nako ea nnete tsa ho lokisa tse kenyelletsang JTAG le trace e kentsoeng.LPC2468 e na le 512 kB ea on-chip high-speed flash memory.Memori ena ea flash e kenyelletsa segokanyimmediamentsi sa memori e pharalletseng ea 128-bit le meralo ea accelerator e nolofalletsang CPU ho etsa litaelo tse latellanang ho tsoa mohopolong oa flash ka lebelo le phahameng la 72 MHz.Karolo ena e fumaneha feela ho LPC2000 ARM microcontroller lelapa la lihlahisoa.LPC2468 e ka phethahatsa litaelo tsa 32-bit ARM le 16-bit Thumb.Tšehetso bakeng sa lihlopha tse peli tsa litaelo li bolela hore baenjiniere ba ka khetha ho ntlafatsa ts'ebeliso ea bona bakeng sa ts'ebetso kapa boholo ba khoutu boemong ba sub-routine.Ha konokono e phethahatsa litaelo ka boemo ba Thumb e ka fokotsa boholo ba khoutu ka ho feta 30 % ka tahlehelo e nyane feela ea ts'ebetso ha ho ntse ho etsoa litaelo sebakeng sa ARM ho eketsa ts'ebetso ea mantlha.Microcontroller ea LPC2468 e loketse lits'ebetso tsa puisano tsa merero e mengata.E kenyelletsa 10/100 Ethernet Media Access Controller (MAC), Controller ea USB e tletseng lebelo / Host / OTG e nang le 4 kB ea endpoint RAM, li-UART tse 'nè, litsela tse peli tsa Controller Area Network (CAN), sebopeho sa SPI, tse peli tse Synchronous. Serial Ports (SSP), li-interface tse tharo tsa I2C, le sebopeho sa I2S.Ho tšehetsa pokello ena ea li-interfaces tsa serial communications ke likarolo tse latelang tsa likarolo;on-chip 4 MHz internal precision oscillator, 98 kB ea RAM kaofela e nang le 64 kB ea SRAM ea moo, 16 kB SRAM bakeng sa Ethernet, 16 kB SRAM ka morero o akaretsang DMA, 2 kB ea SRAM e tsamaisoang ke betri, le Mookameli oa Memori ea Kantle ( EMC).Likarolo tsena li etsa hore sesebelisoa sena se tšoanelehe hantle bakeng sa likhokahano le li-converter tsa protocol.Ho tlatsana le li-controller tse ngata tsa puisano, bokhoni ba ho ts'oara lintho tse ngata, le likarolo tsa memori ke li-timers tse fapaneng tsa 32-bit, 10-bit ADC e ntlafalitsoeng, 10-bit DAC, li-unit tse peli tsa PWM, lithapo tse 'ne tse sitisang kantle, le mela e fihlang ho 160 e potlakileng ea GPIO.LPC2468 e kopanya 64 ea lithakhisa tsa GPIO ho hardware e thehiloeng Vector Interrupt Controller (VIC) e bolelang hore lintho tsena tse kenang ka ntle li ka hlahisa litšitiso tse bakoang ke bohale.Likarolo tsena kaofela li etsa hore LPC2468 e tšoanelehe haholo bakeng sa taolo ea indasteri le lits'ebetso tsa bongaka.
