NXP Semiconductors Microcontroladores de señal mixta MagniV S12ZVL de Freescale
Los microcontroladores de señal mixta MagniV S12ZVL deFreescale son una familia de MCU de 16 bits para automoción que utilizan la tecnología NVM + UHV de 180 nm que ofrece la capacidad de integrar componentes analógicos de 40 V. Esta familia utiliza muchas características de la cartera de productos S12 existente. Las características diferenciadoras particulares de esta familia son el núcleo S12Z mejorado y la integración de módulos analógicos de "alta tensión", incluido el regulador de tensión (VREG) y una capa física de red de interconexión local (LIN). La familia S12ZVL incluye código de corrección de errores (ECC) en RAM, FLASH y EEPROM para diagnóstico o almacenamiento de datos, un convertidor de analógico a digital (ADC) rápido y un bucle con bloqueo de fase con modulación de frecuencia (IPLL) que mejora el rendimiento EMC. La familia S12ZVL ofrece una solución optimizada con la integración de varios componentes del sistema claves en un único dispositivo, lo que optimiza la arquitectura del sistema y consigue un importante ahorro de espacio.
