1 / 5 page R80515 8-bit Microcontroller Megafunction General Description The R80515 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 ASICs and FPGAs.
