Both the FA510 CPU core and FA526 CPU core are the general-purpose 32-bit embedded RISC processors, including a synthesized CPU core, a Memory Management Unit (For FA526 only), separate caches, scratchpads, and other functional blocks. These CPU cores are implemented with the ARMv4® instruction set. Moreover, the configurable features are available for the caches, scratchpads, and write buffers. Both the FA526 and FA510 can operate at the frequencies of up to 300 MHz at 0.13 µm process and 500 MHz at 90 nm process, respectively, in the worst-case conditions (The worst process corner, temperature, and voltage supply are as defined as in the industrial standard). Faraday, long being one of a few certified ARM architecture licensees, is recognized as a leading provider of the CPU technology. Both the FA526 CPU core and 510 CPU core are certified to be fully compliant with the ARM® CPU cores. Due to this unique collaboration between ARM® and Faraday, the FA CPU cores users are able to utilize the full range of the development tools designed for the ARM® cores.
