PicoBlaze 8-bit Microcontroller

  • Bundled With:
    • Vivado Design Suite

Product Description

PicoBlaze™ is a fully embedded 8-bit RISC microcontroller core optimized for 7 series and older AMD FPGA architectures. This reference design is offered free to AMD users, and comes with an easy to-use code assembler KCPSM6 (or KCPSM3 for older FPGA families),  VHDL and Verilog source code, simulation models, comprehensive documentation and reference designs.

Key Features and Benefits

  • Supports UltraScale, Virtex 7, Kintex 7, Artix 7, Zynq and older AMD FPGA families
  • Very small size as small as 26 slices depending on device family
  • Up to 4K 18-bit instructions


  • Up to 240MHz performance
  • Everything in FPGA - no external components required
  • Highly integrated for implementing non-time critical state machine
  • Predictable fast interrupt response
