NXP Semiconductors LPC4300 Cortex™-M4 / M-0 Dual-Core MCUs

NXP Semiconductors LPC4300 series microcontrollers (MCUs) boast the world's first asymmetrical dual-core digital signal controller architecture, featuring ARM® Cortex™-M4 and Cortex-M0 processors. These NXP Cortex-M4 MCUs with Cortex-M0 co-processors bring the advantage of developing a digital signal processor (DSP) and MCU applications within a single architecture and development environment.

The LPC4300 series Cortex-M4 processor combines the benefits of an MCU with high-performance digital signal processing features such as single-cycle MAC, Single Instruction Multiple Data (SIMD) techniques, saturating arithmetic, and a floating-point unit. The Cortex-M0 co-processor off-loads many of the data movement and I/O handling duties that can drain the bandwidth of the Cortex-M4 core. With its dual-core architecture and unique set of configurable peripherals, NXP Semiconductors LPC4300 MCUs enable the development of a wide range of applications, such as motor control, power management, industrial automation, robotics, medical, automotive accessories, and embedded audio.
