What SCI Semiconductor does
SCI Semiconductor Ltd. is a UK-based fabless semiconductor company that develops and commercialises the ICENI family of microcontrollers, which deliver hardware-enforced memory safety through the CHERIoT (Capability Hardware Enhanced RISC Instructions for IoT) architecture. Built on the RISC-V RV32E instruction set and leveraging Microsoft's open-source CHERIoT-Ibex processor core, ICENI devices replace traditional pointers with unforgeable, bounded capabilities that enforce spatial and temporal memory safety by construction, eliminating approximately 70% of modern embedded-software CVEs at the hardware level. The company complements its silicon with a full software stack including the CHERIoT RTOS, an LLVM-based toolchain, and fine-grained compartmentalisation primitives, with ICENI devices fabricated at GlobalFoundries in Dresden using 22FDX process technology. First commercial silicon was announced in March 2026, the same month the product won embedded world Best in Show.
The company targets customers in critical national infrastructure, defence and aerospace, medical devices, automotive, and industrial automation—verticals where memory-safety vulnerabilities in legacy C/C++ codebases create systemic risk and regulatory exposure under the EU Cyber Resilience Act, IEC 62304, and IEC 62443-4. SCI's commercial offering spans hardware sales of ICENI microcontrollers, IP licensing of proprietary system IP and accelerators for customer-specific SoC engagements, and development systems (FPGA platforms including Arty A7 and lowRISC Sonata). The company sells through a two-tier distribution model with EPS Global and Astute Group for worldwide reach, complemented by a direct enterprise sales motion and an ICENI Early Access Program for select design-in partners. Named customer traction is nascent: Google Research is disclosed as an initial ICENI customer, with lowRISC positioned as a technology collaborator.
Founded in 2022 by Haydn Povey (ex-Arm, founder of Secure Thingz which sold to IAR Systems) and Krishna Anne, SCI is headquartered in Sheffield with an engineering centre of mass in Cambridge and a US presence in Santa Clara. The company raised £2.5 million in seed funding in May 2025 led by Mercia Ventures, and appointed former Arm CTO Dipesh Patel as Board Chair in March 2026. It is a founding member of the CHERI Alliance CIC alongside Microsoft, lowRISC, the University of Cambridge, Codasip, and the FreeBSD Foundation.

SCI Semiconductor competitors and assessment
Company assessmentEmerging players
- Raspberry Pi: Designs its own RISC-V-based RP2350 MCU and Arm-based microcontrollers. Increasingly relevant as a low-cost RISC-V MCU competitor and as a channel for developer mind-share in the embedded space.
- Tenstorrent: RISC-V-based AI and compute IP/silicon company. Competes for engineering talent and high-performance RISC-V design-wins rather than embedded MCUs, but overlaps on RISC-V commercial silicon.
Broad incumbents
- Microchip Technology: PIC and SAM (Cortex-M) MCU vendor serving industrial and IoT. Competes for the same critical-infrastructure and industrial design-wins and brings mature MPLAB and Harmony ecosystems.
- Arm: Dominant MCU and application-processor IP licensor whose Cortex-M family is the primary incumbent SCI displaces. Arm also built the Morello CHERI prototype, making it a direct architectural comparator and partner.
- Infineon Technologies: Security-focused MCU and PSoC vendor (PSoC, AURIX, TRAVEO) widely deployed in automotive and industrial. Direct competitor in safety- and security-critical embedded applications.
- NXP Semiconductors: Established automotive and industrial MCU vendor (Cortex-M, Kinetis, S32K). Competes head-on in the same critical-infrastructure, automotive, and industrial verticals SCI targets.
- STMicroelectronics: STM32 family is the volume leader in 32-bit MCUs across industrial, medical, and consumer. Establishes the incumbent benchmark for ecosystem breadth, tooling, and price-performance.
Direct peers
- lowRISC: Open-source hardware IP nonprofit and CHERI Alliance co-founder that maintains the Sonata FPGA platform used for CHERIoT prototyping. Closest architectural and ecosystem peer.
- Codasip: RISC-V processor IP company and CHERI Alliance founding member. Competes in custom compute IP and is also pursuing memory-safe extensions, overlapping directly with SCI's licensing and SoC engagement model.
- SiFive: Leading commercial RISC-V IP and silicon vendor; competes for the same design-wins in embedded and IoT MCUs and is a primary alternative for customers considering CHERI-based parts.
