  • SmartEEPROM (integrated EEPROM emulation algorithm)
  • Read while write (Any bank can be read while programming the other one)
  • All NVM sections are memory mapped to the AHB, including calibration and system configuration
  • 32-bit APB interface for commands and control
  • Programmable wait states for read optimization
  • Regions can be individually protected or unprotected
  • Additional protection for boot loader
  • Supports device protection through a security bit
  • Interface to Power Manager to power-down flash blocks while in sleep modes
  • Can optionally wake up on exit from sleep or on first access
