Digital Core Design

The Power of Intellectual Property


Simplicity, high efficiency and great performance - these three features make the 8051 microcontrollers still very popular. Using everywhere 32-bit, heavy RISC processor is pointless, when an 8-bit CPU can do the tasks more economically and eco-friendly, due to much lower power and ASIC area consumption.

Digital Core Design portfolio includes the most powerful DQ80251 architecture, which is more than 75 times faster than the 80C51 and has 50% more efficient code space utilization, comparing to the classic 8051.

Digital Core Design has a complete portfolio of 8051 processors, consisting of: 

which avails faster architecture and smaller ASIC area, than any other competitors’ 8051 solution. Each family is embedded with the DoCD JTAG/TTAG real-time, non-intrusive debugging system.
