Temporal LatchTM and MICETM Enabled SEU Immune RHBD 90nm CMOS Standard Cell Library
Micro-RDC developed a comprehensive Radiation Hardened by Design (RHBD) cell library for ASIC design using the IBM 9LP 90nm CMOS Process.

Micro-RDC’s RHBD designs include the following technologies to provide electronic integrated circuits with radiation hardening for digital logic architecture, ensuring robust, reliable performance:

Temporal Latch Technology for SEU Immunity 
  • The Cell Library incorporates Micro-RDC's patented Temporal Latch technology for SEU immunity for synchronous designs up to 125 MHz with support for both synchronous and asynchronous resets. 
 MICE for Very High Speed Logic 
  • For clock frequencies up to a GHz, cells are provided using Micro-RDC's patented MICE technology for immunity to SEU and SET. Designers can tradeoff area/power and speed by selecting the correct cells for the desired radiation hardness. For a description of MICE technology see the presentation "Multiply-Interlocked Cell Digital Logic Architecture for SEU and SET Immunity" in the 2012 SEE Symposium.
