The DFPIC165X is a low-cost, high performance, 8-bit, fully static soft IP Core, intended to operate with fast memory (typically on-chip). The core has been designed with a special concern about low power consumption.

The DFPIC165X software is compatible with the PIC16C54, PIC16C55, PIC16C56, PIC16C57 and PIC16C58 industry standards. It has a modified RISC architecture (2 times faster than original implementation).
The DFPIC165X has enhanced core features and configurable hardware stack. The separate instruction and data buses allow a 12 bit wide instruction word, with the separate 8-bit wide data. The DFPIC165X typically achieves a 2:1 code compression and a 8:1 speed improvement, over other 8-bit microcontrollers in its class. The Core has 24 I/O lines and an 8-bit timer/counter, with an 8-bit programmable prescaller.
