1.General descriptionThe LPC4350/30/20/10 are ARM Cortex-M4 based microcontrollers for embeddedapplications which include an ARM Cortex-M0 coprocessor, up to 264 kB of SRAM,advanced configurable peripherals such as the State Configurable Timer (SCT) and theSerial General-Purpose I/O (SGPIO) interface, two High-speed USB controllers, Ethernet,LCD, an external memory controller, and multiple digital and analog peripherals. TheLPC4350/30/20/10 operate at CPU frequencies of up to 204 MHz.The ARM Cortex-M4 is a next generation 32-bit core that offers system enhancementssuch as low power consumption, enhanced debug features, and a high level of supportblock integration. The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses aHarvard architecture with separate local instruction and data buses as well as a third busfor peripherals, and includes an internal prefetch unit that supports speculative branching.The ARM Cortex-M4 supports single-cycle digital signal processing and SIMDinstructions. 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 whichis code- and tool-compatible with the Cortex-M4 core. The Cortex-M0 coprocessor offersup to 204 MHz performance with a simple instruction set and reduced code size.2.Features and benefits Cortex-M4 Processor core ARM Cortex-M4 processor, running at frequencies of up to 204 MHz.
