8051 High-speed 8-bit RISC Microcontroller
"The AllianceCORE R80515 from CAST is a fast, single-chip, 8-bit microcontroller that executes all ASM51 instructions. It has the same instruction set as the 80C31, but executes operations an average of 8 times faster. The R80515 provides software and hardware interrupts, extra timer features, power management, and Infinion peripherals support. On-chip debugging is an option.The microcode-free, strictly synchronous design was developed for reuse in FPGAs.
