NXP Semiconductors Micro-contrôleur 32 bits ARM Cortex-M0+ LPC11U6x

La gamme de microcontrôleurs à 32 bits ARM Cortex-M0+ LPC11U6x de NXP tire parti de l'utilisation facile et de la conception flexible de la gamme LPC11Uxx primée de NXP avec un ensemble de caractéristiques encore améliorées, comprenant un cœur ARM® Cortex™-M0+ plus économe en énergie, nettement plus de mémoire Flash et SRAM, plus de communications série, un nouveau CAN 2 MS/s et des minuteurs plus polyvalents. Ces caractéristiques supplémentaires permettent au LPC11U6x de s'attaquer à une plus large plage d'applications sur les marchés grand public, commerciaux et industriels tels que la mesure et le recueil des données, le routage par câble et sans fil, l'équipement médical portatif et les accessoires de jeu/PC, entre autres. Le LPC11U6x étend ses options de mémoire en doublant la mémoire Flash à 256 ko et en triplant la SRAM à 36 ko. Des exigences d'E/S plus rigoureuses sont prises en charge par la connectivité série étendue, incluant 5 interfaces USART, 2 I2C, 2 SPI et jusqu'à 80 GPIO, avec un nouveau CAN 12 canaux, 12 bits, 2 MS/s pour une bande passante plus large et une entrée de plus grande précision.
