NXP Semiconductors Microcontroladores LPC11E6x ARM Cortex-M0+ de 32 bits – NXP | Mouser

Os microcontroladores LPC11E6x 32-bit ARM Cortex-M0+ da NXP fornecem aos engenheiros uma escolha mais ampla na seleção de microcontroladores de nível de entrada projetados para condições adversas de funcionamento comuns em muitos aplicativos industriais, de iluminação e de automação industrial. O LPC11E6x está disponível em três variações de memória e de pacotes e oferece excepcional eficiência de energia, conseguida através de um ARM®;Cortex-M0™ com perfis de núcleo e de potencia que permitem várias opções de economia de energia, dependendo das exigências de aplicação. As opção de memória incluem até 256 kB de flash, 36 kB de RAM e EEPROM de 4 kB. São fornecidas características analógicas de alta precisão, incluindo um Conversor analógico a digital (ADC – 2 Msps, 12 canais e 12 bits), e ampla conectividade por meio de I2C interfaces SPI, USART e até 80 GPIO. O LPC11E6x usa um SCTimer/PWM on-chip para fornecer recursos de temporização avançadas. Este bloco único pode operar como a maioria dos timers tradicionais, e inclui uma máquina de estado para dar aos programadores um grau mais elevado de controle de tempo. Ele pode ser configurado como vários PWM (módulos por largura de pulso), como um PWM com controle de tempo morto e como diversas outras funções que não podem ser duplicadas com temporizadores tradicionais. Também disponível, o Cookbook SCTimer/PWM fornece uma coleção de exemplos e notas de uso que ajuda os programadores a implantar rapidamente funções de sincronização para aplicativos LPC11E6x.
