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 Motorola MC68HC11K microcontrollers, integrating major peripheral functions on-chip. This includes an asynchronous serial communication interface (SCI), a synchronous serial peripheral interface (SPI), a main 16-bit free-running timer system with input capture, output compare lines, and a real-time interrupt function. The sub-system also includes an 8-bit pulse accumulator. The memory expansion unit permits up to sixteen 32K byte banks of external memory to be addressed, expanding the memory space up to 1MB. It features self-monitoring circuitry for protection against system errors and has a COP watchdog for software failure protection. Its two software-controlled power-saving modes make it ideal for automotive and battery-driven applications. Additionally, the D68HC11K can be equipped with an external ADC Controller to use external ADCs as internal components. It is fully customizable, allowing configurations tailored to customer requirements. The IP core comes with a comprehensive set of tests and an automated test bench for easy validation. It is fully synthesizable and compatible with all FPGA and ASIC vendors, thereby ensuring its wide applicability across different platforms and systems.
