NXP LPC5500 Series

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.

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.
