The DFPIC1655X is a low-cost, high performance, 8-bit, fully static soft IP Core, intended to operate with fast memory. The core has been designed with a special concern about low power consumption, in combination with high performance.
The DFPIC1655X software is compatible with the industry standard PIC 16XXX Microcontrollers. It has a modified RISC architecture (2 times faster than original implementation).
The DFPIC1655X has enhanced core features, configurable hardware stack and multiple internal and external interrupt sources. The separate instruction and data buses allow a 14-bit wide instruction word, with a separate 8-bit wide data.
The power-down SLEEP mode allows user to significantly reduce power consumption and “wake up” the controller, through several external and internal interrupts and resets. An integrated Watchdog Timer with it’s own dedicated clock signal, provides protection against software lock-up. DFPIC1655X is delivered with fully automated testbench, complete set of tests and DoCD on-chip hardware debugger, allowing easy package validation, at each stage of SoC design flow.
Each of the DCD’s PIC Core, has built-in support for DCD Hardware Debug System, called DoCD . It is a real-time hardware debugger, which provides debugging capability of a whole System on Chip (SoC).
Unlike other on-chip debuggers, the DoCD 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, SFRs, including user defined peripherals, data and program memories.
