D80530
8-bit Microcontroller
Core
The D80530 core implements a fast, single-chip, 8-bit microcontroller that executes all
ASM51 instructions. It has the same instruction set as the 80C31, but its Dallas archi-
tecture executes operations an average of 2.5 times faster.
The D80530 provides software and hardware interrupts, a serial communications inter-
face, extra timer features, and power management.
The microcode-free, strictly synchronous design was developed for reuse in ASICs and
FPGAs. Scan insertion is straightforward.
Applications
The D80530 can be utilized for a variety of applications including:
• Embedded microcontroller systems
• Data computation and transfer
• Communication systems
• Professional audio and vide
