DF6808

DF6808 8-bit MCU IP Core – High-Performance, Fully Customizable 68HC08 Compatible

The DF6808 is a high-performance 8-bit MCU IP Core with advanced on-chip peripheral capabilities, fully binary-compatible with the Motorola 68HC08 8-bit microcontroller. Leveraging DCD’s FAST architecture, the DF6808 delivers up to 3.2× higher performance compared to the original 68HC08, achieving 45–100 million instructions per second, making it ideal for automotive, battery-powered, and industrial SoC applications.

The DF6808 is fully customizable, delivered in the exact configuration to meet project requirements, ensuring no wasted silicon or unused features. Its standard configuration includes major on-chip peripherals:

Key Features & Capabilities:

• Dual Serial Interfaces: Full-duplex UART (SCI) and synchronous SPI for versatile communication.

• 16-bit Free-Running Timer: Two input capture lines and two output-compare lines for precise timing.

• Reliability & Safety: On-chip self-monitoring, COP watchdog, and illegal opcode detection with non-maskable interrupt.

• Power Efficiency: WAIT and STOP software-controlled low-power modes for energy-sensitive designs.

• Fully Automated Validation: Delivered with a complete test bench and verification suite for seamless SoC integration.

• DoCD™ Hardware Debug Support: Built-in real-time debugger enabling non-intrusive SoC debugging of registers, program/data memory, SFRs, and user-defined peripherals.

The DF6808 IP Core combines high performance, low power, and advanced peripherals, making it perfect for automotive electronics, battery-powered embedded systems, and industrial SoCs.

Applications: Automotive, battery-driven embedded systems, industrial control, and general-purpose SoCs.
