LPC55S6x MCU Family - Dual-core Arm® Cortex®-M33 MCU Series with TrustZone and 40nm Flash Technology
The LPC5500 MCU Series leverages the most recent Arm® Cortex®-M33 technology, combining significant product architecture enhancements and greater integration over previous generations; offering 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.
The LPC55S6x MCU family, the first product family in the LPC5500 Series, 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. In addition, the LPC55S6x MCU family provides benefits from 40nm NVM based process technology cost advantages, broad scalable packages, and memory options, as well as a robust enablement including MCUXpresso Software and Tools ecosystem and low-cost development boards.
