IP Description: 

"The DFPIC1655X is a low-cost, high-performance, 8-bit, fully static soft IP Core, dedicated for operation with fast memory (typically on-chip). The core has been designed with a special concern about low power consumption. The DFPIC1655X is software compatible with the industry standard PIC16C554 and PIC16C558. It employs a modified RISC architecture (2 times faster than original implementation). The DFPIC1655X have 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 the separate 8 -bit wide data. The DFPIC1655X typically achieve a 2:1 code compression and a 8:1 speed improvement over other 8-bit microcontrollers in their class. The power-down mode SLEEP allow user to reduce power consumption. User can wake up the controller from SLEEP through several external and internal interrupt and reset. An integrated Watchdog Timer with it's own clock signal provides protection against software lock-up.
