NXP - LPC5500 - M33 MCU Series

NXP - LPC5500 - M33 MCU Series

NXP's LPC5500 featured product at Sourcengine, the largest e-commerce marketplace for electronic components.

NXP Semiconductors has married next-generation performance with the peace of mind provided by end-to-end encryption with its LPC5500 MCU series. The mass-market family of microcontrollers utilizes ARMs Cortex-M33 technology to provide significantly enhanced architecture, integration, and power consumption compared to prior generation MCUs.

With the LPC5500 series, NXP has introduced the world’s first general-purpose Cortex-M33 microcontrollers. The LPC55S6x MCU family leverages a proprietary DSP accelerator to offer 10x cycle reduction, a significant improvement in signal processing capability. These high-efficiency chips utilize Arm’s new Armv8-M architecture to achieve new levels of performance.  

In addition, the LPCXpresso55S69 development boards offer flexible and powerful platforms for NXP’s Cortex-M MCUs. The boards allow for expansion using Arduino, Mikroe, and PMod headers and feature a high-speed USB port and Link2 debugging probe. In tandem with the LPC55S69 dual-Cortex-M33 core processors, they allow for rapid evaluation and prototyping.

Furthermore, NXP’s Cortex-M33 microcontrollers feature advanced security functionality thanks to their SRAM PUF-based root of trust and provisioning. The LPC5500 single and dual-core MCUs also provide real-time execution from encrypted images (internal flash) and system-wide asset protection via Arm’s TrustZone technology.

Boasting seven scalable families and a host of memory and package options, the LPC5500 MCU series are a versatile and secure solution for a range of consumer and industrial Internet of Things (IoT) products.
