LPC4370FET100E Overview

The LPC4370 are Arm Cortex-M4 based microcontrollers for embedded applicationswhich include an Arm Cortex-M0 coprocessor and an Arm Cortex-M0 subsystem formanaging peripherals, 282 kB of SRAM, advanced configurable peripherals such as theState Configurable Timer (SCT) and the Serial General Purpose I/O (SGPIO) interface,two High-speed USB controllers, Ethernet, LCD, an external memory controller, andmultiple digital and analog peripherals including a high-speed 12-bit ADC. The LPC4370operate 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 LPC4370 include an application Arm Cortex-M0 coprocessor and a second Arm Cortex-M0 subsystem for managing the SGPIO and SPI peripherals. The Arm Cortex-M0 core is an energy-efficient and easy-to-use 32-bit core which is code- and tool-compatiblewith the Cortex-M4 core. Both Cortex-M0 cores offer up to 204 MHz performance with asimple instruction set and reduced code size.
