London Stock Exchange welcomes EnSilica plc to AIM

EnSilica is a designer and supplier of mixed signal ASICs (Application Specific Integrated Circuit). ASICs are Integrated Circuits or semiconductor chips developed for a particular use or product rather than for general purpose usage.  ASICs help differentiate products through optimised hardware making products smaller, faster, lower power, improved security, add novel functionality, improving supply chain security and protecting product from being copied.


The Company has expertise in the area of designing complex mixed signal ASICs. Mixed signal ASICs combine digital and analogue functions onto a single chip. They are the most complex chips to design hence the highest value.

The Company was established in 2001 as a specialist consultancy designing ICs on a contract basis. Using over 15 years’ first-hand industry experience, the Company was able to begin transitioning to a fabless design and supply business model in 2016. EnSilica now provides an end-to-end service for the design and supply of ASICs, outsourcing certain elements such as the wafer fabrication of the manufacturing and packaging to third parties – otherwise known as a Fabless Semiconductor Model. This is a proven model for growth and profitability used by many European companies including Dialog Semiconductor, Cambridge Silicon Radio, Wolfson and Nordic Semiconductor.

EnSilica’s customers currently range from global corporations and OEMs to technology start-ups, including automotive Tier 1s, industrial enterprises, as well as large software companies and service providers developing proprietary hardware.  EnSilica is an approved supplier to some of the world’s largest automotive and industrial OEMs and Tier 1 suppliers.
