DFPIC&DRPIC FAMILY OVERVIEW
The family of DCD DFPICXX & DRPICXX IP Cores combine a high–performance, low cost, and
small compact size, offering the best price/performance ratio in the IP Market. The DCD’s Cores are
dedicated for use in cost-sensitive consumer products, computer peripherals, office automation,
automotive control systems, security and telecommunication applications.
DCD’s DFPICXX & DRPICXX IP Cores family contains four 8-bit microcontroller Cores to best
meet your needs: DFPIC165X 12-bit program word, DFPIC1655X 14-bit program word, and
DRPIC1655X and DRPIC166X single cycle microcontrollers with 14-bit program word. All three
microcontroller cores are binary compatible with widely accepted PIC16C5X and PIC16CXXX. They
employ a modified RISC architecture two or four times faster than the original ones.
The DFPICXXX & DRPICXX IP Cores are written in pure VHDL/VERILOG HDL languages which
make them technologically independent. All of the DFPICXX & DRPICXX family members supports a
power saving SLEEP mode and allows the user to configure the watchdog time-out period and a
number of hardware stack levels. DFPICXX & DRPICXX can be fully customized according to
customer needs.
