IDT79R3081 RISController is a military and commercial temperature range microcontroller
The document introduces the IDT R3051 family of high-performance 32-bit microprocessors, specifically focusing on the IDT79R3081 (and its voltage variant IDT79RV3081). These processors are designed for cost-sensitive but high-performance applications by integrating functional units onto a single chip to reduce system costs. The R3081 extends the capabilities of the family by adding resources such as larger caches and optional floating-point acceleration while maintaining compatibility with existing systems.
