NXP Semiconductors LPC43Sx 32-bit ARM Cortex-M4 based microcontrollers feature an ARM Cortex-M0 coprocessor, up to 264kB of SRAM, advanced configurable peripherals such as the State Configurable Timer/PWM (SCTimer/PWM) and the Serial General-Purpose I/O (SGPIO) interface, two high-speed USB controllers, Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals. The design allows LPC4350/30/20/10 to operate at CPU frequencies of up to 204MHz. The ARM Cortex-M4 provides a next generation 32-bit core that offers system enhancements such as low power consumption, enhanced debug features, and a high level of support block integration. The ARM Cortex-M4 CPU includes a 3-stage pipeline. The Harvard architecture provides separate local instruction and data buses as well as a third bus for peripherals. An internal prefetch unit supports speculative branching. The ARM Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A hardware floating-point processor is integrated in the core. The ARM Cortex-M0 coprocessor is an energy-efficient and easy-to-use 32-bit core which is code- and tool-compatible with the Cortex-M4 core. The Cortex-M0 coprocessor delivers up to 204MHz performance with a simple instruction set and reduced code size. Learn More
