Retune DSP is now part of NXP.Find out more.
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 feature 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. The LPC5500 series of MCUs is part of NXP's EdgeVerse™edge computingplatform.
With SRAM PUF-based root of trust and provisioning, real-time execution from encrypted images (internal flash), and asset protection with Arm®TrustZone®-M.
With integrated power management IC (DC-DC) and dedicated co-processors for signal processing and cryptographic acceleration.
Comprised of several families within this series, all benefiting from 40 nm cost advantages, broad scalable package and memory options, robust enablement including MCUXpresso Software and Tools ecosystem and a low-cost development board.
