LPC4337FET256,551 Overview

The LPC4357/53/37/33 are Arm Cortex-M4 based microcontrollers for embeddedapplications which include an Arm Cortex-M0 coprocessor, up to 1 MB of flash and136 kB of on-chip SRAM, 16 kB of EEPROM memory, advanced configurable peripheralssuch as the State Configurable Timer (SCT) 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 LPC4357/53/37/33 operate at CPUfrequencies 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,designed as a replacement for existing 8/16-bit microcontrollers, offers up to 204 MHzperformance with a simple instruction set and reduced code size.
