PEmicro Legacy Hardware Support Notice (In Effect As of 1 Oct. 2021)

Oct 01, 2021

Beginning October 1, 2021 the latest versions of PEmicro software will only be tested against and designed to work with the following PEmicro hardware interfaces:


  • USB ML Universal, Rev. C or later
  • USB ML Universal FX, Rev. B or later


  • Cyclone LC Universal
  • Cyclone LC ARM
  • Cyclone FX Universal
  • Cyclone FX ARM

These changes are necessitated by evolving operating systems and target requirements/features. 

Older hardware models are not guaranteed to work for future drivers, firmware, and software. This includes older models of Multilink debug probes manufactured circa 2015 and earlier, and older models of Cyclone flash programmers, manufactured circa 2016 and earlier.  

PEmicro customers can take advantage of PEmicro's Cyclone Trade-In or Multilink Trade-In programs to exchange their legacy hardware for a discount towards the purchase of new hardware. Users that have concerns or require additional help can contact us at

Frequently Asked Questions
