AbstractThe many different generations of integrated circuit (IC) technologies required for new space exploration systems demand designs operate at multiple and often incompatible voltages. Extended utilization of current and development of new space exploration systems require multiple voltage levels be successfully integrated to interface technologies. NASA's micro-satellites and space exploration missions, like the Space Technology 5 (ST5) Project, are current examples of systems that employ a variety of voltage levels. Spacecraft have limited supply voltages and power at their disposal and this encourages the use of a higher percentage of low voltage microelectronics.  To build complete systems there continues to be a common problem of mixing old and new equipment operating at different voltages.  ASI's FlexfetTM CMOS rad-hard reconfigurable bi-directional level shifters (ReBiLS) will allow NASA improved capability to design, develop and implement multi-level voltage systems. The ASI ReBiLS Phase II project will generate prototypes for stand-alone and embedded bidirectional level shifters. A stand-alone ReBiLS device will allow designers to provide efficient bi-directional communication between existing or COTS components operating at different voltages. An embedded ReBiLS cell will be demonstrated in a CULPRiT ULP circuit to demonstrate the on-chip integration of low-voltage, low-power core logic with high-voltage I/O.
