EnSilica production tape-out milestone of industrial ASIC

Production revenues estimated to be worth in excess of US$30m over 7 years

EnSilica, a leading chip maker of mixed signal ASICs (Application Specific Integrated Circuits), is pleased to announce that it has reached the key production tape-out milestone for the design and supply of an industrial ASIC which incorporates an industrial Arm based controller.

The project award was announced on 25 July 2022.

The ASIC is for a leading European industrial Original Equipment Manufacturer ("OEM") and is a key component in their factory automation controller systems.

A tape-out starts the manufacturing of the mask sets used for production of the ASIC. Based on the OEM customer's volume projections the ASIC supply has revenues worth in excess of US$30 million over seven years. We are now moving into the post-tape out phase of the project and expect to have samples in Spring 2024, and release-to-production in late Autumn 2024, following silicon validation and qualification.

Ian Lankshear, Chief Executive Officer of EnSilica plc, commented:

"I would like to thank our talented engineering team for their diligent work that has led to the smooth execution of this key first project for our leading OEM customer.

We expect this to lead to further design wins as a consequence of the increasing number of opportunities in this industrial market. There is a trend to include artificial intelligence (AI) processing accelerators in new ASICs. Also, and driven by new EU legislation, addressing advanced cyber security protection is increasingly becoming a requirement. EnSilica is well placed to take advantage of these trends leading to opportunities to re-design a range of ASICs."
