LPC1227FBD64/301,1 IC MCU 32BIT 128KB FLASH 64LQFP

wehewehe

Hoʻonui ka LPC122x i ka NXP's 32-bit ARM microcontroller continuum a kuhikuhi i kahi ākea o nā noi ʻoihana ma nā wahi o ka hale hana a me ka automation home.Loaʻa ka pōmaikaʻi mai ka ARM Cortex-M0 Thumb hoʻonohonoho aʻoaʻo, loaʻa ka LPC122x i ka 50% kiʻekiʻe o ka code density i hoʻohālikelike ʻia me ka microcontroller 8/16-bit maʻamau e hana ana i nā hana maʻamau.Hoʻokomo pū ka LPC122x i kahi waihona hoʻokaʻawale ROM i hoʻopaʻa ʻia no Cortex-M0, e hāʻawi ana i nā manawa he nui i ka hana helu o nā hale waihona puke e pili ana i ka polokalamu, a me ka manawa pōʻaiapili deterministic i hui pū ʻia me ka nui o ka helu flash code.Hiki i ka ARM Cortex-M0 pono ke kōkua i ka LPC122x e hoʻokō i ka mana haʻahaʻa haʻahaʻa no nā noi like.Hoʻohana ka LPC122x i nā alapine CPU a hiki i 45 MHz. Hāʻawi lākou i kahi ākea o nā koho hoʻomanaʻo flash, mai 32 kB a 128 kB.ʻO ka holoi ʻana i ka ʻaoʻao 512-byte liʻiliʻi o ka hoʻomanaʻo uila e lawe mai i nā pono hoʻolālā he nui, e like me ka EEPROM emulation ʻoi aku ka maikaʻi, kākoʻo boot-load mai kekahi interface serial a me ka maʻalahi o ka hoʻolālā ʻana i loko o ke kahua me ka hoʻemi ʻana i nā koi buffer RAM ma-chip.ʻO ka hoʻopiha piha ʻana o ka LPC122x he 10-bit ADC, ʻelua mea hoʻohālikelike me ka puka manaʻo puka puka, ʻelua UART, hoʻokahi interface SSP/SPI, hoʻokahi kikowaena I2C-bus me nā hiʻohiʻona Fast-mode Plus, kahi Windowed Watchdog Timer, kahi mea hoʻoponopono DMA, he ʻenekini CRC, ʻehā mau mea hoʻohana maʻamau, he 32-bit RTC, he 1% oscillator kūloko no ka hoʻokumu ʻana i ka baud rate, a hiki i 55 mau pine General Purpose I/O (GPIO).
