NXP Semiconductors MCU LPC18Sx ARM® Cortex®
La serie LPC18Sx di NXP Semiconductors include microcontroller (MCU) basati su ARM Cortex-M3 con funzioni di sicurezza per applicazioni integrate. Il modello ARM Cortex-M3 presenta un core di prossima generazione che offre miglioramenti di sistema come un consumo a bassa potenza, funzionalità di debug potenziate e un elevato livello di integrazione del blocco di supporto. La CPU ARM Cortex-M3 integra una pipeline a 3 stadi e funziona a frequenze della CPU fino a 180 MHz. L'architettura Harvard fornisce bus di dati e istruzioni locali separati nonché un terzo bus per periferiche. Inoltre la CPU ARM Cortex-M3 CPU ha un'unità di prefetch interna che supporta la diramazione speculativa. Gli MCU LPC18Sx basati su ARM Cortex-M3 includono fino a 200 kB di SRAM su chip, funzioni di sicurezza con motore AES, un'interfaccia SPI (SPIFI) quadrupla, un sottosistema PWM/timer a stato configurabile (SCTimer/PWM), due controller USB ad alta velocità, Ethernet, LCD, un controller di memoria esterno e molteplici periferiche digitali e analogiche.
