NXP Semiconductors MCU ARM Cortex-M0+ de 32 bits LPC11U6x

La familia ARM Cortex-M0+ de 32 bits LPC11U6x de NXP se basa en la facilidad de uso y la flexibilidad de diseño del premiado catálogo LPC11Uxx con diversas características mejoradas, que incluyen un núcleo ARM® Cortex™-M0+ más eficiente energéticamente, un aumento considerable de la memoria flash y SRAM, más comunicaciones en serie, un nuevo ADC de 2 Msps y temporizadores más versátiles. Estas características adicionales permiten a la familia LPC11U6x adaptarse a una mayor gama de aplicaciones en mercados de consumo, comerciales e industriales, como por ejemplo, medición y recopilación de datos, enrutamiento con cables e inalámbrico, equipos médicos portátiles y accesorios para PC/juegos, entre otros. El LPC11U6x amplía las opciones de memoria al duplicar la memoria flash hasta 256 KB y triplicar la SRAM hasta 36 KB. Los requisitos más exigentes de E/S se cumplen mediante conectividad en serie ampliada, que incluye 5 USART, 2 IDC, 2 SPI y hasta 80 GPIO, junto con un nuevo ADC de 12 canales, 12 bits de 2 Msps para obtener mayor ancho de banda y mejor precisión en la entrada.
