DR80390CPU High Performance 8-bit Microcontroller ver 3.10 OVERVIEW DR80390CPU is a high performance, area optimized soft core of a single-chip 8-bit embedded controller dedicated for operation with fast (typically on-chip) and slow (off-chip) memories. The core has been designed with a special concern about low power consumption. Additionally an advanced power management unit makes DR80390CPU core perfect for portable equipment where low power consumption is mandatory. DR80390CPU soft core is 100% binarycompatible with the industry standard 80C390 & 8051 8-bit microcontroller. There are two configurations of DR80390CPU: Harward where external data and program buses are separated, and von Neumann with common program and external data bus. DR80390CPU has RISC architecture 6.7 times faster compared to standard architecture and executes 65-200 million instructions per second. This performance can also be exploited to great advantage in low power applications where the core can be clocked up to seven times more slowly than the original implementation for no performance penalty. DR80390CPU is delivered with fully automated testbench and complete set of tests allowing easy package validation at each stage of SoC design flow.
