What Phoenix Semiconductor does

Phoenix Semiconductor Corporation is a privately held semiconductor company founded in July 2023 and headquartered in Austin, Texas. The company has developed a patent-pending process for recreating discontinued, end-of-life, or legacy semiconductor chips without requiring new silicon, a fabrication facility, or original wafers, producing form, fit, and function equivalent drop-in replacements. Its core technology applies modern IC design, packaging, and manufacturing techniques to replicate legacy chip designs from original specifications, with chip recreation cycles measured in months rather than the 1-2 year timelines of traditional fab-based approaches. Phoenix's product portfolio spans four chip categories: Memory (EEPROM, SRAM, Flash, DRAM), Logic (PAL, TTL, CMOS, programmable logic), Mixed Signal (ADC, DAC, interface, analog front-end), and Power (DC/DC converters, regulators, rectifiers, drivers), with named recreations including the XCF Platform Flash PROM family, Datel 12-bit and 16-bit DACs, and the Signetics 82S100 Bipolar FPLA.

The company sells to long-cycle markets where platforms operate for 30-50 years, with Defense & Aerospace as the primary segment (Lockheed Martin, NAVAIR, DLA, prime defense contractors), followed by Oil & Gas, Industrials & Infrastructure, and Healthcare. Phoenix pursues a dual go-to-market combining enterprise field sales directly to defense primes and government agencies (with multiple SBIR contracts) and channel sales through a master distribution agreement with Avnet signed in October 2025. Revenue is generated through unit-priced hardware sales of recreated chips and government contract awards, with free engineering samples provided to qualified customers for validation. The company is backed by national-security-focused venture investors including J2 Ventures, RTX Ventures, Lockheed Martin Ventures, and IronGate Capital Advisors, with ~$8.5M raised across 2024-2025 seed rounds, achieved ISO 9001 certification in June 2026, and is operating with a small 1-10 person team currently producing approximately 75 SKUs.

Revenue model

1. Legacy Chip Sales: Phoenix generates revenue through the sale of recreated legacy semiconductor chips to customers. Chips are sold directly and through Avnet distribution. The company produces drop-in replacement chips for discontinued components, selling units at various price points based on chip complexity and volume requirements.
2. Sample Chip Distribution: Phoenix provides free engineering samples and test reports to qualified customers as part of customer adoption and validation process, with subsequent larger orders following successful qualification.

Core offering

Phoenix Semiconductor recreates legacy and discontinued semiconductor chips using a patent-pending process that does not require new silicon, a fabrication facility, or the original wafers. The company delivers drop-in functional equivalents of obsolete microelectronics to OEMs and government end-users facing parts shortages.

Product overview

Phoenix Semiconductor operates as a single unified offering—their legacy chip recreation service—supplemented by four distinct chip product categories (Memory, Logic, Mixed Signal, and Power chips) and multiple market-specific vertical solutions (Defense & Aerospace, Oil & Gas, Industrials & Infrastructure, Healthcare). The company's patent-pending process recreates discontinued semiconductor chips without requiring new silicon, a fabrication facility, or original wafers, producing form, fit, and function compatible drop-in replacements. Their catalog includes specific products such as the XCF Platform Flash PROM family, Datel DAC chips (12-bit and 16-bit), and the Signetics 82S100 FPLA. Products are distributed exclusively through Avnet and designed for long-cycle markets requiring high mix of parts at lower volumes.

Partnerships

Five partnerships are on record, tiered core and strategic.

• AvnetcoreChannel Partner/ Reseller/ Distributor · 14 October 2025Phoenix Semiconductor signed a master distribution agreement with Avnet, Inc. in October 2025. Avnet serves as the exclusive distribution partner handling all point-of-sale opportunities. The partnership initially focuses on high-demand discontinued semiconductors with plans to expand. Avnet customers gain access to Phoenix's legacy chip solutions to avoid costly redesigns and production delays.
• Texas State UniversitystrategicStrategic or Co-development PartnerPhoenix Semiconductor partners with Texas State University through a public-private partnership advancing collaborative projects in engineering, materials science, and applied technologies. The partnership prioritizes workforce development and hands-on engineering training.
• University of Texas at AustinstrategicStrategic or Co-development PartnerPhoenix Semiconductor sponsors a research project with UT Austin to recreate the Z80 microprocessor, one of the oldest chips still in use today. Collaboration brings awareness and sparks student interest in solving legacy chip supply issues.
• University of California Los Angeles (UCLA)strategicStrategic or Co-development PartnerPhoenix Semiconductor collaborates with UCLA's Electrical and Computer Engineering Department on co-optimization of semiconductor technologies with computing systems, as well as the IMPACT+ Center focused on future semiconductor technologies.
• University of Texas Rio Grande ValleystrategicStrategic or Co-development PartnerPhoenix partners with the Institute for Advanced Manufacturing (IAM) at UTRGV, connecting university research with industry needs in advanced materials, robotics, automation, and precision manufacturing.
