90 is an ultra high performance, speed optimized soft core of a single-chip 8bit embedded controller dedicated for operation with fast (typically on-chip) and slow (offchip) memories. It supports up to 8 MB of linear code and 16 MB of linear data spaces. The core has been designed with a special concern about performance to power consumption ratio. This ratio is extended by an advanced power management unit PMU. DP80390 soft core is 100% binarycompatible with the industry standard 80390 & 8051 8-bit microcontrollers. There are two configurations of DP80390: Harward where internal data and program buses are separated, and v
