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 performance of 45 – 100 million instructions per second. The DF6805 has a FAST architecture that is 4.1 times faster comparing to the original implementation. In the standard configuration the core has major peripheral functions integrated on-chip. The DF6805 Microcontroller Core contains 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 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 fully automated test bench with complete set of tests, allowing easy package validation at each stage of SoC design flow. Each DCD’s DF68XX Cores has a built-in support for a proprietary Hardware Debug System called DoCD™. It is a real-time hardware debugger which provides debugging capability of a whole System-on-Chip (SoC). Unlike other on-chip debuggers, the DoCD™ provides a non-intrusive debugging of running application. It can halt, run, step into or skip an instruction, read/write any contents of microcontroller, including all registers, SFRs, including user defined peripherals, data and program memories.

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
