8-bit Microprocessor
Description
D6802 8-bit MPU IP Core – MC6802 Compatible, Low-Power Microprocessor IP
The D6802 is a synthesizable 8-bit microprocessor (MPU) IP Core, fully binary-compatible with the Motorola MC6802. Designed as a drop-in replacement for legacy MC6802 microprocessors, the D6802 enables seamless migration of existing software into modern ASIC and FPGA-based System-on-Chip (SoC) designs—without code changes or revalidation.
Optimized for low-power embedded applications, the D6802 features two software-controlled power-saving modes: WAIT and HALT. These modes significantly reduce power consumption, making the core especially suitable for automotive electronics, battery-powered systems, and long-lifecycle industrial designs.
