Features

Arm® Cortex®-M33 Core

  • Arm Cortex-M33 processor, running at a frequency of up to 150 MHz
  • TrustZone, floating point unit (FPU) and memory protection unit (MPU)
  • Arm Cortex-M33 built-in nested vectored interrupt controller (NVIC)
  • Non-maskable interrupt (NMI) input with a selection of sources

Co-Processor

  • Arm Cortex-M33 co-processor
    • Running at a frequency of up to 150 MHz
    • The configuration of this instance does not include MPU, FPU, DSP, ETM, and TrustZone
    • System tick timer
  • CASPER crypto co-processor to enable hardware acceleration for certain asymmetric cryptographic algorithms
  • PowerQuad hardware accelerator for (fixed and floating point) DSP functions

Security Features

  • Arm TrustZone enabled
  • PRINCE module for real-time encryption of data being written to on-chip flash and decryption of encrypted flash data during reading to allow asset protection
  • AES-256 encryption/decryption engine
  • Secure hash algorithm (SHA2) module supporting secure boot with dedicated DMA controller
  • Physical unclonable function(PUF) using dedicated SRAM for silicon fingerprint. PUF can generate, store, and reconstruct key sizes from 64 to 4096 bits. Includes hardware for key extraction
  • Random number generator (RNG)
  • 128-bit unique device serial number for identification (UUID)
  • Secure GPIO
  • The LCP55S6x is part of the EdgeLock Assurance program
