8-bit FAST Microcontroller
The DF6811K is an advanced 8-bit MCU IP Core with highly sophisticated, on-chip peripheral capabilities. DCD’s soft core is binary-compatible with industry standard Motorola 68HC11K 8-bit microcontroller. It has an improved FAST architecture – approximately 4 times faster compared to the original implementation. In the standard configuration the core has major peripheral functions integrated on-chip. The Core can be provided in configurations that match the following microcontrollers:
There are two serial interfaces: an asynchronous serial communications interface (SCI) and a separate synchronous serial peripheral interface (SPI). The main 16-bit, free-running timer system has three input capture lines, five output-compare lines and a real-time interrupt function. An 8-bit pulse accumulator subsystem can count external events or measure external periods. 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 save additional power. These modes make the DF6811K IP Core especially attractive for automotive and battery-driven applications. The DF6811K Microcontroller Core can be equipped with the ADC Controller, allowing use of an external ADC Controller with standard ADC software. The ADC Controller makes external ADC’s visible as internal ADC’s in original 68HC11K Microcontrollers. The core is fully customizable – delivered in the exact configuration to meet users requirements. There is 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 Core has a built in support for a proprietary Hardware Debug System called DoCD™ – a real-time hardware debugger which provides debugging capability of a whole System-on-Chip (SoC). Unlike other on-chip debuggers, the DoCD™ provides non-intrusive debugging of the running application. It can halt, run, step into or skip an instruction, read/write any contents of the microcontroller, including all registers, SFRs, including user defined peripherals, data and program memories.
- FAST architecture – 4 times faster than the original implementation
- Software compatible with 68HC11 industry standard
- 10 times faster multiplication
- 16 times faster division
- 256 bytes of remapped System Function Registers space (SFRs)
- De-multiplexed Address/Data Bus, to allow easy memory connection
- Core can also be used without I/O wrapper, so each peripheral functions pins will be separated from I/O ports lines.
- Two power saving modes: STOP, WAIT
- Ready pin allows Core to operate with slow program and data memories.
- Fully synthesizable
- Static synchronous design
- No internal reset generator or gated clock
- Positive edge clocking and no internal tri-states
- Scan test ready
- 1 GHz of virtual clock frequency, compared to original implementation
- USB, Ethernet, I2C, SPI, UART, CAN, LIN, HDLC, Smart Card interfaces available

Power of Innovation is our primary target. That’s why our R&D focuses on every IP Core detail. As a result of that concern, some unique solutions were born. One of them is the D68XX on-Chip Debugger (DoCD™) which is a complete debugging system, dedicated for all 68XX Cores offered by DCD.Read more
