16-Bit Rad Hard MCU Good To 300 krads

Initially introduced as the industry’s first radiation-hardened version of the MCS-96-compatible, 16-bit microcontroller, the UT80CRH196KD is now guaranteed to 300 krads versus 100 krads before. The enhanced device includes an onset LET threshold for single event upsets of 25 MeV-cm2/mg and a single event latchup immunity to LET >128 MeV-cm2/mg. It operates at 20 MHz and integrates 1 KB of SEU hardened SRAM, software and hardware timers, synchronous and asynchronous UARTs, high-speed capture inputs and outputs, and three pulse-width modulated outputs. An on-board ALU supports 16-bit multiplies, 32- and 16-bit divides, and other logical and arithmetic operations. Other new features include an early read/write indication signal that provides the memory decode logic an advanced indication of the type of memory operation that is being performed. The 68-lead QFPs cost $1,895 each/10,000. For more details, call Teresa Farris at AEROFLEX UTMC, Colorado Springs, CO. (719) 594-8035.
