INTRODUCTION

The UT80CRH196KD is compatible with industry standard’s MCS-96 instruction set. The UT80CRH196KD is supported by commercial hardware and software development tools.

Built on UTMC’s Commercial RadHardTM epitaxial CMOS technology, the microcontroller is hardened against ionizing dose and charged particles. The microcontroller’s on-board 1000 byte scratch-pad SRAM and flip-flops can withstand charged particles with energies up to 25 MeV-cm2

/mg.
