NXP Semiconductors LPC18Sx Arm Cortex MCUs

NXP Semiconductors LPC18Sx family includes Arm® Cortex®-M3 based microcontrollers (MCUs) with security features for embedded applications. The Arm Cortex-M3 features a next-generation core that provides system enhancements such as low power consumption, enhanced debug features, and a high level of support block integration. The Arm Cortex-M3 CPU integrates a 3-stage pipeline and operates at CPU frequencies of up to 180MHz. The Harvard architecture offers separate local instruction and data buses as well as a third bus for peripherals. In addition, the Arm Cortex-M3 CPU has an internal prefetch unit to support speculative branching. The NXP LPC18Sx Arm Cortex-M3 based MCUs include up to 200kB of on-chip SRAM, security features with AES engine, a quad SPI Flash Interface (SPIFI), a State Configurable Timer/PWM (SCTimer/PWM) subsystem, two High-speed USB controllers, Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals.
