8-bit FAST Microcontrollers Family
The DF6805 is an advanced 8-bit MCU IP Core with highly sophisticated, on-chip peripheral capabilities. The DF6805 soft core is binary-compatible with the industry standard Motorola 68HC05 8-bit microcontroller. It can achieve the performance of 45 – 100 million instructions per second. The DF6805 has a FAST architecture that is 4.1 times faster compared to the original implementation. In the standard configuration, the core has major peripheral functions integrated on-chip. The DF6805 Microcontroller Core contains a full-duplex UART – Asynchronous Serial Communication Interface (SCI) and can be also equipped with the Synchronous Serial Peripheral Interface (SPI). The main 16-bit, free-running timer system has two input capture lines and two output-compare lines. Self-monitoring circuitry is included on-chip to protect against system errors. The Computer Operating Properly (COP) watchdog system protects against software failures. An illegal opcode detection circuit provides a non-maskable interrupt if an illegal opcode is detected. Two software-controlled power-saving modes – WAIT and STOP are available to preserve additional power. These modes make the DF6805 IP Core especially attractive for automotive and battery-driven applications. The DF6805 is fully customizable – delivered in the exact configuration to meet your requirements. There’s no need to pay extra for unused features and wasted silicon. It includes a fully automated test bench with a complete set of tests, allowing easy package validation at each stage of the SoC design flow. Each DCD’s DF68XX Cores has built-in support for a proprietary Hardware Debug System called DoCD™. It is a real-time hardware debugger that provides debugging capability of a whole System-on-Chip (SoC). Unlike other on-chip debuggers, the DoCD™ provides a non-intrusive debugging of running applications. It can halt, run, step into or skip an instruction, and read/write any contents of the microcontroller, including all registers, and SFRs, including user-defined peripherals, data, and program memories.
All DCD’s IP Cores are technology independent which means that they are 100% compatible with all FPGA & ASIC vendors e.g.

Power of Innovation is our primary target. That’s why our R&D focuses on every single IP Core detail. As a result of that concern, some unique solutions were born. One of them is the 68XX on-Chip Debugger (DoCD™), which is a complete debugging system dedicated for all 68XX Cores offered by DCD.Read more
