World’s smallest 8051 IP Core.
Ideal for power consumption sensitive applications
The DT8051 – area optimized, the tiny soft core of a single-chip 8-bit embedded microcontroller, based on the World’s fastest and most popular DP8051 core available for over 18 years. The DT8051 softcore is 100% binary-compatible with the industry standard 8051 8-bit microcontrollers. It has a very low gate count architecture, giving 6 650 ASIC gates for the complete system, including the DoCD on-chip debugger. Dhrystone 2.1 benchmark program runs exactly 8.1 times faster than the original 80C51 at the same frequency. The same C compiler was used for benchmarking the core vs 80C51, with the same settings. The DT8051 includes a 2-wire DoCD on-chip debugger (TTAG™), up to eight external interrupt sources, an advanced Power Management Unit, Timers 0&1, I/O bit addressable Ports, full duplex UART, and an interface for external SFR. The DT8051 Core has built-in support for the 2-wire TTAG™ interface – DCD’s Hardware Debug System, called DoCD™. This version of the debugger is dedicated to applications where the number of external pins is limited. The DT8051 is delivered with a fully automated test bench and complete set of tests, allowing easy package validation at each stage of the SoC design flow. Each of DCD’s 8051 Cores has built-in support for the Hardware Debug System called DoCD™. It is a real-time hardware debugger that provides debugging capability of a whole System-on-Chip (SoC). Unlike other on-chip debuggers, the DoCD™ provides non-intrusive debugging of a running application. It can halt, run, step into or skip an instruction, set breakpoints, and watchpoints, and read/write any contents of the microcontroller, including all registers, internal and external program memories, and all SFRs, including user-defined peripherals.

Power of Innovation is our primary target. That’s why our R&D focuses on every IP Core detail. As a result of that concern, some unique solutions were born. One of them is the on-Chip Debugger (DoCD™), which is a complete debugging system, dedicated for DCD's DQ80251/DQ8051/DT8051/DP8051x/DP80390x Microcontroller Cores.Read more
