INTRODUCTION
The UT82CRH51A is an enhanced version of the industry standard, Universal Synchronous/Asynchronous Receiver Transmitter (USART), designed to provide data communications between subsystem. The UT82CRH51A USART is built using UTMC’s Commercial RadHardTM epitaxial CMOS technology and is ideal for space applications.
