The D68HC11K is a synthesizable soft IP Core Microcontroller, fully compatible with the industry standard. It can be used as a direct replacement for the following Motorola MC68HC11K microcontrollers: MC68HC11K0, MC68HC11K1, MC68HC11K4, MC68HC711K4, MC68HC11KS2, MC68HC711KS2. In a standard configuration of the core, major peripheral functions are integrated on-chip. An asynchronous serial communication interface (SCI) and a 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. The memory expansion unit (with six address extension lines) allows up to sixteen 32K byte banks of external memory to be addressed in either of two bank windows, up to 1MB. Features like self-monitoring on-chip circuitry protect against system errors. Two power-saving modes, WAIT and STOP, are especially attractive for automotive and battery-driven applications. The D68HC11K can optionally include an ADC Controller for external ADC integration. The IP is fully customizable, delivering an exact configuration to meet user requirements. It includes a comprehensive automated test bench, set of tests, and is compatible with DCD’s DoCD™ real-time hardware debugger for non-intrusive debugging. The D68HC11K is technology agnostic, ensuring compatibility with all FPGA and ASIC vendors.
