The HS-RTX2010RH is a radiation-hardened 16-bit microcontroller with on-chip timers, an interrupt controller, a multiply-accumulator, and a barrel shifter. It is particularly well suited for space craft environments where very high speed control tasks which require arithmetically intensive calculations, including floating point math to be performed in hostile space radiation environments.

This processor incorporates two 256-word stacks with multitasking capabilities, including configurable stack partitioning and over/underflow control.

Instruction execution times of one or two machine cycles are achieved by utilizing a stack oriented, multiple bus architecture. The high performance ASIC Bus, which is unique to the RTX product, provides for extension of the microcontroller architecture using off-chip hardware and application specific I/O devices.

RTX Microcontrollers support the C and Forth programming languages. The advantages of this product are further enhanced through third party hardware and software support. Combined, these features make the HS-RTX2010RH an extremely powerful processor serving numerous applications in high performance space systems. The HS-RTX2010RH has been designed for harsh space radiation environments and features outstanding Single Event Upset (SEU) resistance and excellent total dose response.
