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

Tsanangudzo

NXP Semiconductors yakagadzira iyo LPC2468 microcontroller yakatenderedza 16-bit/32-bit ARM7TDM-S CPU musimboti ine chaiyo-nguva debug interfaces inosanganisira zvese JTAG uye yakamisikidzwa trace.Iyo LPC2468 ine 512 kB ye-on-chip yakakwirira-kumhanya flash memory.Iyi flash memory inosanganisira yakakosha 128-bit wide memory interface uye accelerator architecture inoita kuti CPU iite mirairo inotevedzana kubva kuflash memory pahupamhi hwe72 MHz system clock rate.Ichi chimiro chinowanikwa chete paLPC2000 ARM microcontroller mhuri yezvigadzirwa.Iyo LPC2468 inogona kuita zvese 32-bit ARM uye 16-bit Thumb mirairo.Tsigiro yemaseti maviri emirairo inoreva mainjiniya anogona kusarudza kukwidziridza kunyorera kwavo kwekuita kana saizi yekodhi pane sub-routine level.Kana iyo musimboti ikaita mirairo muThumb state inogona kuderedza kodhi saizi neinopfuura 30 % nekungorasikirwa kudiki mukuita uchiita mirairo muArM state inokwirisa core performance.Iyo LPC2468 microcontroller yakanaka kune akawanda-chinangwa ekukurukurirana maapplication.Inosanganisira 10/100 Ethernet Media Access Controller (MAC), USB yakazara-speed Device/Host/OTG Controller ine 4 kB ye endpoint RAM, mana maUART, maviri Controller Area Network (CAN) chiteshi, SPI interface, maviri Synchronous. Serial Ports (SSP), matatu I2C interfaces, uye I2S interface.Kutsigira iyi muunganidzwa we serial communications interfaces ndeaya anotevera maficha zvikamu;an on-chip 4 MHz yemukati precision oscillator, 98 kB ye RAM yakazara inosanganisira 64 kB yemunharaunda SRAM, 16 kB SRAM yeEthernet, 16 kB SRAM yezvakawanda DMA, 2 kB yebhatiri powered SRAM, uye External Memory Controller ( EMC).Aya maficha anoita kuti mudziyo uyu unyatso kukodzera magedhi ekutaurirana uye maprotocol converters.Kuzadzisa akawanda serial ekutaurirana anodzora, anochinja-chinja mawachi, uye ndangariro maficha akasiyana 32-bit timers, yakagadziridzwa 10-bit ADC, 10-bit DAC, maviri PWM mayunitsi, mana ekunze mapini ekuvhiringidza, uye anosvika zana nemakumi matanhatu ekukurumidza GPIO mitsetse.Iyo LPC2468 inobatanidza makumi matanhatu neina emapini eGPIO kune Hardware yakavakirwa Vector Interrupt Controller (VIC) zvinoreva kuti izvi zvekunze zvinopinda zvinogona kuburitsa kumucheto-kunokonzeresa kukanganisa.Ese aya maficha anoita kuti LPC2468 inyanyokodzera kudzora kwemaindasitiri uye masisitimu ekurapa.
