Product:Flip80251 Typhoon

Flip80251 Typhoon looks like an 8051 from the outside while benefiting from the capabilities of an 80251 inside!

 

Flip80251 Typhoon provides a natural upgrade path from 8051-based application thanks to its 8-bit interfaces.
Flip80251 Typhoon delivers a processing power of 0.22 DMIPS/MHz, up to 24 times higher than standard 8051.
Flip80251 Typhoon looks like an 8051 from the outside while benefiting from the capabilities of an 80251 inside!
It is the best compromise for 8051-based application requiring impressive processing power improvements when no hardware modifications are possible.

Key Benefits of Flip80251 Typhoon

  • Compatibility with 8051 microcontrollers
    • 8-bit SFR bus and memory interfaces compatibility avoiding hardware modifications and enabling reuse of peripherals developed for 8051
    • 8051 compatible memory mapping facilitating reuse of existing application software in assembly mode
    • Optional 100 % binary code compatibility
    • Easy performance upgrade from existing 8051-based circuit
  • Improved performances compared to standard 8051
    • x24 times faster
    • x8 times less consuming
    • Bigger address space
    • Superior code density enabling to use smaller and thus lower power memories
  • Architecture specificities
    • 8-bit like architecture with 80251 performances
  • Power modes: idle (core clock off), clock down (core and peripherals clock off)

Deliverables

  • Verilog or VHDL netlist
  • Source code (optional)
  • Testbench with documentation for checking the functionality of any configuration of the Flip80251 Hurricane at any representation level (RTL down to silicon).

Robustness is ensured

For more than 15 years, Dolphin Integration has built a testsuite for checking the functionality of any configuration of the Flip80251 Typhoon at any representation level (RTL down to silicon).The testbenches have evolved a lot thanks to users feedback.
The testbench is delivered with its documentation to our microcontroller core users so that they can apply it on their own project and ensure functionality.
