Cryptoprocessors IP cores: AES

Tiempo AES IP core offers an unmatched performance over power consumption ratio. Operating at a wide and variable voltage range, this core enable very fast transaction for embedded applications. It is also highly secured against attacks thanks to its asynchronous implementation.

Key benefits

AES block-diagram
  • Ultra-low power consumption
  • Ultra-low current peaks
  • Work at low and variable voltage
  • Resistant to power and fault attacks

Key Features

  • Fast execution of standard AES ciphering and deciphering algorithms
  • Fully asynchronous and delay insensitive
  • Available as Verilog netlist[1] ready for P&R
  • Optional: Verilog netlist[1] secured against hardware attacks
  • Optional: Verilog netlist[1] strengthened for ultra-low noise and ultra low EMI


Targeted applications are chips for smartcards (with or without contact), RFID, tags, systems embedding NFC technology and other secured applications.
