History

[edit]

EnSilica was founded in 2001 by Ian Lankshear and Richard Hamer.[1] Initially established as a specialist consultancy designing integrated circuits under contract, EnSilica transitioned to a fabless design and supply business model in 2016[2] and in May 2022 EnSilica plc was floated on the London Stock Exchange's Alternative Investment Market (AIM).[3]

EnSilica's first industrial supply ASIC (Application Specific Integrated Circuit) in 2016 was for a 'leading European industrial original equipment manufacturer (OEM)'. While the company did not publicly disclose the specific name of the OEM at the time, the project was focused on industrial and factory automation products and was valued at over $30 million across a seven-year period.[4]

In December 2021 AST SpaceMobile selected EnSilica[5] to deliver a 'next-generation ASIC with state-of-the-art performance and power efficiency to maximise the unique capabilities of the company’s network. The ASIC will be a key communications component of the spacecraft electronics payload for AST SpaceMobile. Subsequently in June 2025 EnSilica announced that first royalty payments have been triggered and an extended royalty agreement has been signed.[6] Although the announcement did not specifically confirm AST SpaceMobile as the customer it is believed to be for AST's Block 2 BlueBird satellites[7] which could launch in September 2025[8]

In July 2024 EnSilica announced a US$7 million order from a new customer for the masking and initial wafer supply for an edge artificial intelligence (AI) processing chip.[9][10] In April 2025 EnSilica stated that the high-value tape-out of the Edge AI chip is expected to commence in the first half of FY2026 (commencing 1st June 2025). It is expected that the associated non-recuring engineering revenue for these services which are only recognised at the tape-out of the chip will contribute approximately £4 million and EBITDA by approximately £3 million in FY2026.[11]

In November 2024 EnSilica reported results including a going concern warning, causing the shares to fall 12% at one stage.[12] In April 2024 after announcing 'customer-side' delays to two contracts EnSilica's shares fell 20%.[13]

In March 2025 the European Space Agency signed a contract with EnSilica to develop a novel multi-band radio frequency receiver on a single chip, designed to simultaneously receive dual signal streams from all current and future satnav constellations to help overcome interference.[14]

In July 2025 Transport for London, International Airlines Group and Admiral Group provided funding towards developing its radar technology for autonomous self-driving vehicles (Unified Neutral Net-Radar) in a development partnership with Radareye.[15]

Grants

[edit]

EnSilica has been the recipient of a number of UK Government and European Union funded research grants.[16][17][18][19] In February 2025 EnSilica was awarded £10.38 million funding over the next three years from the UK Space Agency for a development project under its Connectivity in Low Earth Orbit (C-LEO) programme. In March 2025 EnSilica was awarded a €2.13 million development contract under the European Space Agency's Navigation Innovation and Support Programme (NAVISP) Element 2 project.[20]

Products and Services

[edit]

EnSilica has delivered application-specific integrated circuit (ASIC) designs and across a number of industries.[21] With integrated circuits for automotive[22], industrial[23], healthcare[24], cryptography[25], artificial intelligence[26], optical networking[27], space[28] and communications[29] markets as the company has broadened its offering since its first ASIC in 2016.

In addition to its ASIC and design service offerings EnSilica provides manufacturing support services for its customers’ own design and development activities.[30]

EnSilica has established relationships with the major silicon IP providers such as Arm Holdings[31], Cadence Design Systems[32], Synopsys[33] and Qualcomm (Alphawave).[34][35] It is also a member of the Design Center Alliance of the Taiwan Semiconductor Company Limited's Open Innovation Platform.[36]
