Synthesizable soft IP Microcontroller, compatible with Motorola MC68HC11K

Digital Core Design has introduced the D68HC11K, a synthesizable soft IP Core Microcontroller, fully compatible with the Motorola MC68HC11K industry standard. It can be used as a direct replacement for the microcontrollers like: MC68HC11K0, MC68HC11K1, MC68HC11K4, MC68HC711K4, MC68HC11KS2 and MC68HC711KS2. In a standard configuration, the core has an integrated on-chip major peripheral functions. 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. – This and additional modes make the D68HC11K IP Core especially attractive for automotive and battery-driven applications – says Jacek Hanke, DCD’s CEO. 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. The MEU extension of memory space can be up to 1MB. Self-monitoring, on-chip circuitry is included, to protect D68HC11K against system errors. To enable optima functionality in design, DCD’s IP Core implements eg:  The Computer Operating Properly (COP) watchdog system, which protects against software failures  An illegal opcode d...
