NXP Semiconductors MCU Cortex-M0+ ARM da 32 bit LPC11E6x

La famiglia di MCU Cortex-M0+ ARM da 32 bit LPC11E6x di NXP è stata realizzata partendo dalla facilità d'uso e dalla flessibilità del disegno della premiata gamma di LPC11Uxx di NXP con molte funzionalità migliorate, compreso un core ARM® Cortex™-M0+ con una migliore efficienza energetica, un aumento significativo della memoria flash e SRAM, maggiori comunicazioni seriali, un nuovo ADC da 2 Msps e timer più versatili. Queste caratteristiche aggiuntive consentono all'LPC11U6x di potere essere utilizzato da un'elevata gamma di applicazioni nei mercati consumer, commerciali e industriali, quali ad esempio le misurazioni, la raccolta dati, l'instradamento cablato e wireless, i dispositivi medicali portatili, gli accessori per PC e i videogiochi. L'LPC11U6x estende le opzioni di memoria raddoppiando la memoria flash a 256 KB e triplicando la SRAM a 36 KB. Sono supportati requisiti di I/O molto più rigorosi per aumentare la connettività seriale, tra cui 5 USART, 2 I2C, 2 SPI e fino a 80 GPIO, insieme a un nuovo ADC a 12 canali, 12 bit, 2 Msps per una maggiore larghezza di banda e un input di maggiore precisione.
