NXP LPC5500 Series sample product image

The LPC5500 MCU series leverages Arm's most recent Cortex-M33 technology, combining significant product architecture enhancements and greater integration over previous generations; with dramatic power consumption improvements and advanced security features including SRAM PUF based root of trust and provisioning, real-time execution from encrypted images (internal flash), and asset protection with Arm TrustZone-M. In addition, the LPC5500 MCU series features seven scalable families, with a broad package and memory options, as well as a comprehensive MCUXpresso Software and Tools ecosystem and low-cost development boards.

  • Accessible security with SRAM PUF based root of trust and provisioning, real-time execution from encrypted images (internal flash), and asset protection with Arm TrustZone-M.
  • Breakthrough in performance efficiency with integrated power management IC (DC-DC) and dedicated co-processors for signal processing and cryptographic acceleration.
  • Comprehensive offering and scalability, comprised of several families within this series, all benefiting from 40nm cost advantages, broad scalable package and memory options, robust enablement including MCUXpresso Software
  • 32uA/MHz performance efficiency with single & dual Cortex-M33 options to bring added performance & power efficiency options
  • Delivering > 370 CoreMarks (96MHz) to ensure time awake is productive


LPC55S6x MCU family

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. An optional second Cortex-M33 core offers flexibility to balance high performance and power efficiency.
