NXP Semiconductors MCUs Kinetis W
O MCU wireless Freescale Kinetis KW2x expande a família de MCU Kinetis bem-sucedida com base no núcleo da CPU ARM Cortex-M4. O Kinetis KW2x integra um transceptor RF 2.4 GHz líder da classe, com um núcleo ARM Cortex-M4 e um sólido conjunto de características para uma solução IEEE 802.15.4 sem fios, confiável, segura e de baixo consumo. Estes MCUs sem fio oferecem até 512 KB de flash, 64 KB de RAM e até 64 KB de FlexMemory. O suporte a Dual PAN permite que o sistema participe simultaneamente em duas redes ZigBee, eliminando a necessidade de vários rádios. As pilhas de protocolos de Software, ferramentas e IDE são compatíveis com os MCUs da Kinetis. O Software de protocolo ZigBee é perfeitamente integrado dentro da ferramenta de desenvolvimento de software Kinetis para criação rápida de sistemas acoplados. Aplicativos típicos incluem Redes de Área Local consistindo em medidores, portais, in-home displays, aplicativos conectados, também controle de rede construída, aplicativos Domóticos com controle de iluminação, HVAC e segurança.
