The DF6811 is an advanced 8-bit MCU IP Core, with highly sophisticated, on-chip peripheral capabilities. DF6811 soft core is binary-compatible with the industry standard Motorola 68HC11 8-bit microcontroller. It has an improved FAST architecture, that is approximately 4 times faster, compared to original implementation. In the standard configuration, the core has integrated on chip, major peripheral functions.
The Core can be provided in configurations, that match the following:
An asynchronous serial communications interface (SCI) and separate synchronous serial peripheral interface (SPI), are included. The main 16-bit, free-running timer system has three input capture and five outputcompare lines and a real-time interrupt function.
An 8-bit pulse accumulator subsystem can count external events or measure external periods. Self-monitoring on-chip circuitry is included, to protect DF6811E from system errors. A 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 conserve additional power. These modes make the DF6811E IP Core especially attractive for automotive and battery-driven applications. The DF6811E has a built-in real time hardware on-chip debugger -DoCDTM, allowing easy software debugging and easy package validation at each stage of SoC
