Actel Extends Core8051s for Line of High-Reliability Axcelerator®, Radiation-Tolerant RTAX and Low-Power IGLOO® FPGAs

Core8051s is an ASM51-compatible 8-bit microcontroller core that can run programs written for the 8051. It contains the main 8051 core logic but no peripheral logic. Core8051s has an APB bus interface that can be used like the SFR bus to easily expand the functionality of the core by connecting it to existing APB IP peripherals. This allows users to configure the core with the peripheral functions (timers, UARTs, I/O ports, etc.) that they need for their application. The 8051s offers a low-cost, low-power complement to the ARM® Cortex™-M1 32-bit microprocessor. For designers of space-flight systems and other high-reliability applications, the 8051s adds a small footprint complement to the successful and popular LEON3-FT 32-bit processor, which currently is acquiring space-flight heritage in Actel RTAX2000S FPGAs. Core8051s is already seeing deployment in designs targeting RTAX-S space-flight FPGAs…
