BRINGING SECURITY AND INTELLIGENCE TO THE IoT EDGE

LPC5500 Series: NXP’s Most Performance Efficient Arm Cortex-M33 Based MCUs

The LPC5500 MCU series leverages Arm’s most recent Cortex®-M33 technology, combining significant product architecture enhancements, greater integration and advanced security over previous generations. The LPC5500 MCU family is part of NXP’s EdgeVerse™ edge computing platform. With 755 CoreMarks and energy use as low as 32 μA/MHz, the LPC5500 MCU series introduces new levels of performance efficiency for the new wave of IoT and industrial applications.

In addition, the LPC5500 MCU series features a unique set of security blocks providing layers of protection for embedded systems while protecting end products from unknown or un expected threats over its life cycle. These blocks include: SRAM PUF for based root of trust and provisioning, real-time execution from encrypted images, TrustZone for system-wide hardware isolation for trusted software and debug authentication capabilities.

The LPC55S6x MCU family builds on the world’s first general-purpose Cortex-M33 based microcontroller introduced with the LPC5500 series. This high-efficiency family leverages the new Armv8-M architecture to introduce new levels of performance and advanced security capabilities including TrustZone-M and co-processor extensions. The LPC55S6x family enables these co-processors extensions and leverages them to bring significant signal processing efficiency gains from a proprietary DSP accelerator offering a 10x clock cycle reduction. In addition, the LPC55S6x MCU family provides a robust enablement including the MCUXpresso Software and Tools ecosystem and a low-cost development board (LPC55S69-EVK).
