Designed as a replacement MCU for a number of MC68HC11K microcontrollers, the 16-bit core 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,” said Jacek Hanke, DCD’s CEO.
Memory expansion unit (with six address extension lines) allows up to sixteen 32kbyte banks of external memory to be addressed in either of two bank windows.
The MEU extension of memory space can be up to 1Mbyte. Self-monitoring, on-chip circuitry is included, to protect D68HC11K against system errors.
Security features include a computer operating properly watchdog system, which protects against software failures. An illegal opcode detection circuit provides a non-maskable interrupt, if illegal opcode is detected.
The core is customised for specific user requirements and includes fully automated testbench with complete set of tests.
The D68HC11K microcontroller core can be equipped with the ADC controller, which allows the usage of external ADC controller with standard ADC software. This ADC controller makes external ADC’s visible in exact the same way as internal ADC’s in original 68HC11K microcontrollers.
For debugging, the D68HC11K has a built-in support for DoCD, a real-time hardware debugger which provides a non-intrusive debugging of running application. It can halt, run, step into or skip an instruction, read/write any contents of microcontroller, including all registers and SFRs, including user defined peripherals, data and program memories.
