Quicklogic EOS S3

The Quicklogic EOS S3 looks like an interesting part:


  • Easy-to-use, low cost dev kit and open source software toolchains integrates into your own work flow​
  • With multiple product delivery packages (CSP, BGA, SiP, Module), you have the flexibility to choose what is best for YOUR system
  • Go from idea to prototype to mass production quickly with the EOS S3 SoC


  • 100% Free and Open Source Tools including:​
  • Zephyr and FreeRTOS for integrated Arm Cortex®-M4F MCU​
  • SymbiFlow supports Verilog-to-bitstream for integrated eFPGA
  • Renode SoC emulation for pre-hardware software development​

I started my career writing assembler code for the 68HC05 ROM based MCU (no flash in those days). These parts could be programmed once, unless you bought a special “windowed” version that could be erased by ultraviolet light (took 30m or so in the UV box). Things have come a long way since then …

I’ve written about Quicklogic before.
