The RTX 2001A is a 16-bit microcontroller which is particularly well suited for very high speed control tasks which are less arithmetically intensive than those tasks which require the full capabilities of the RTX 2000. In these application areas, this product offers cost/performance advantages, surpassing competing 8 - and 16-bit microcontrollers by up to 50X.

Pin compatible to the RTX 2000, this processor incorporates two 64-word stacks with most of the features provided on the RTX 2000, including on-chip timers and an enhanced Interrupt Controller. Instruction execution times of one or two machine cycles are achieved by utilising a stack oriented multiple bus architecture . The high performance ASIC Bus, which is unique to the RTX family of products, provides for extension of the microcontroller architecture using off-chip hardware acceleration logic and application specific I/O devices. RTX Microcontrollers support high level languages such as Forth and C The advantages of this product are further enhanced through the use of the peripherals and development system support Harris provides for the RTX family.

Combined, these features make the RTX 2001A an extremely powerful processor, providing the ability to meet numerous applications in low cost, high performance systems.

The RTX 2001A has been designed and fabricated utilizing the Harris Advanced Standard Cell and Compiler Library. As part of the Harris family of compatible cell libraries, the RTX 2001A architecture can also be incorporated into customer ASIC designs.
