Almost 10. times faster than standard 80C51 at the same frequency
Ultimate low gate count
Power Management Unit
The DT8051 is area optimized
, tiny soft core, of a single-chip 8-bit embedded microcontroller, based on World's fastest and most popular DP8051 core, available since over 8 years. DT8051 soft core is 100% binary-compatible with the industry standard 8051 8-bit microcontroller. DT8051 has very low gate count architecture, giving 7 150 ASIC gates for complete system, including 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 of the core vs 80C51, with the same settings. DT8051 includes 2-wire DoCD on-chip debugger (TTAGTM), up to eight external interrupt sources, advanced Power Management Unit, Timers 0&1, I/O bit addressable Ports, full duplex UART and interface, for external SFR. DT8051 Core has built-in support for the 2-wire TTAGTM interface - DCD Hardware Debug System, called DoCDTM
. This version of debugger is dedicated for applications, where number of external pins is limited.
The DT8051 is delivered with fully automated testbench
and complete set of tests
, allowing easy package validation, at each stage of SoC design flow.
Each of the DCD's 8051 Core, has built in support for the DCD Hardware Debug System, called DoCDTM
. It is a real-time hardware debugger
, which provides debugging capability of a whole System on Chip (SoC).<br />
Unlike other on-chip debuggers, the DoCDTM
provides non-intrusive debugging
of running application. It can halt, run, step into or skip an instruction, set breakpoints, watchpoints, read/write any contents of microcontroller, including all registers, internal and external program memories, all SFRs, including user defined peripherals. <a href="http://ndcd.dcd.pl/page/154/docd/" target="_blank">More details about DCD on Chip Debugger</a>
