Overview

The LPC55S66JBD100K is a high-performance dual-core ARM Cortex-M33 microcontroller designed for secure embedded applications. It operates up to 150MHz and features advanced security hardware including TrustZone, a Programmable Logic Unit (PLU), and the PRINCE engine for real-time encrypted execution from its 256KB of flash.

Why Choose This Part

This MCU offers a unique combination of efficiency and security through its Armv8-M architecture, providing 8.5mA at 48MHz run current alongside specialized crypto accelerators. The PRINCE engine enables on-the-fly encryption/decryption of flash content with minimal latency, ensuring IP protection without sacrificing performance.

Applications

Secure IoT Gateways
Utilizes TrustZone and SRAM PUF for hardware-isolated execution and secure identity management in connected environments.
Industrial Edge Processing
Leverages the dual-core architecture and integrated DSP instructions to process sensor data locally while maintaining system responsiveness.
Secure USB Peripherals
Integrated USB support combined with the crypto engine allows for secure data transfer and hardware-authenticated interface devices.
