The high-performance UT0.6 CRH/SRH gate array family features densities up to 600,000 equivalent gates and is available in MIL-PRF-38535 QML Q and V product assurance levels and is radiation-tolerant. The Commercial RadHard TM and Strategic RadHardTM silicon is fabricated at American Microsystems Incorporated (AMI) using a minimally invasive processing module, developed by UTMC, that enhances the total dose radiation hardness of the field and gate oxides while maintaining circuit density and reliability. In addition, for both greater transient radiation-hardness and latchup immunity, the UTMC 0.6 process is built on epitaxial substrate wafers. Developed using UTMC's patented architectures, the UT0.6 CRH/SRH gate array family uses a highly efficient continuous column transistor architecture for the internal cell construction. Combined with state-of-the-art placement and routing tools, the utilization of available transistors is maximized using three levels of metal interconnect. The UT0.6 CRH/SRH family of gate arrays is supported by an extensive cell library that includes SSI, MSI, and 54XX equivalent functions, as well as configurable RAM and cores. UTMC's core library includes the following functions: Intel 80C31 equivalent
