The D68HC11F is a synthesisable SOFT Microcontroller IP Core, fully compatible with the Motorola 68HC11F1 industry standard. It can be used as a direct replacement for the 68HC11F1 Microcontrollers.
In the standard configuration, the core has integrated on-chip major peripheral functions. An asynchronous serial communications interface (SCI) and separate synchronous serial peripheral interface (SPI) are included. The main 16-bit, free-running timer system, contains input capture and 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 on-chip circuitry is included to protect the D68HC11F 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 conserve additional power. These modes make the D68HC11F IP Core especially attractive for automotive and battery-driven applications.
