Analog IP aids physical attack mitigation in low-power IoT SoCs
IP specifically designed to aid in physical attack mitigation, such as fault injection, in SoC applications, especially in the IoT field.

Vidatronic, Inc., has announced an addition to its low-power analog IP portfolio, the 22 nm Series, to mitigate physical attack techniques, such as fault injection, in ASIC and systems on a chip (SoC) applications. Leveraging Vidatronic’s 22 nm IP will enable customers to achieve unparalleled levels of performance, security, and reliability while minimizing cost. With nearly a decade of experience delivering advanced analog and power management IP solutions globally, this new IP strengthens the company’s position as a leader in innovative analog technologies in advanced processes.

Vidatronic recently entered into a partnership with Open Five, a self-contained custom silicon business unit of SiFive that offers customizable and differentiated SoC IP. As a partner, Open Five now offers Vidatronic’s analog IP alongside their own to enhance their portfolio for segment-specific silicon based on optimized processor and SoC IP targeted to customers’ requirements.

“As physical security attacks on SoCs become more prevalent, it has become increasingly important to implement technology within the chip aimed to prevent these types of threats,” said Moises Robinson, Vidatronic President and Co-Founder. “Some physical security attacks involve perturbation techniques used to cause unintended behavior of the silicon. These techniques, like fault injection attacks that involve voltage and clock manipulation, can often be prevented by using hardware-security cores. Vidatronic’s 22 nm IP Series was specifically designed to aid in physical attack mitigation on SoCs.”

The 22 nm Series contains several IP cores:

  • Low Dropout (LDO) Voltage Regulator IP equipped with Vidatronic’s Power Quencher technology that enables low-power applications with no external components required;
  • Bandgap Voltage Reference IP that includes an analog temperature sensor for voltage and temperature supervision;
  • Oscillator IP with two very accurate clock outputs for system clock monitoring;
  • Comparator IP with four programmable input threshold settings for voltage supervision;
  • 10-Bit SAR ADC/DAC IP which supports both ADC and DAC operating modes as well as fast and slow sampling modes for system testing.

Additionally, these IP cores in the 22 nm
