  • Up to 20MIPS throughput at 20MHz
  • On chip 2 cycle multiplier
  • 128KBytes of in system self programmable flash program memory
  • 4KBytes EEPROM
  • 16KBytes internal SRAM
  • Data retention: 20 years at 85°C/100 years at 25°C
  • Optional boot code section with independent lock bits
  • In system programming by on chip boot program
  • True read-while-write operation
  • Programming lock for software security
  • QTouch and QMatrix acquisition
  • Up to 64 sense channels
  • Boundary scan capabilities according to the JTAG standard
  • Extensive On chip debug support
