Microchip Technology’s work with TSMC is aimed at strengthening manufacturing options, while its AI strategy spans edge devices, developer software and data-center infrastructure. The partnership adds a specialized 40nm manufacturing path at TSMC’s Japan Advanced Semiconductor Manufacturing (JASM) subsidiary in Kumamoto, Japan; it is not a claim that all Microchip products are made there. Separately, Microchip is building tools and platforms for AI workloads, while TSMC invests in the advanced processes, packaging and capacity used across the wider semiconductor industry.
What the Microchip–TSMC relationship adds
In April 2024, Microchip said its expanded relationship with TSMC would enable specialized 40nm capacity at JASM in Kumamoto, Japan. Microchip framed the additional manufacturing path as a way to improve supply-chain resilience and geographic redundancy, and to provide greater assurance of supply for products serving automotive, industrial and networking applications.
The announcement describes a manufacturing arrangement, not a new chip architecture or a disclosed product-by-product production plan. Microchip did not publish an independent measure of how much the arrangement changes delivery reliability, output or market share. Senior vice president of worldwide manufacturing and technology Michael Finley said customers could have confidence designing Microchip products into applications and platforms, citing resilient manufacturing capabilities.
Why geography and process choice matter
Having manufacturing capacity in another geography can give a supplier an additional path to support customers if a region or facility faces disruption. The announcement’s 40nm detail identifies the process node associated with this specialized capacity; it does not establish that the arrangement replaces other manufacturing sources or that every Microchip product can use it.

Microchip’s AI work covers edge devices and software
Microchip’s AI strategy is broader than a single chip. Its February 2026 release describes production-ready, full-stack edge-AI solutions built around microcontrollers (MCUs) and microprocessors (MPUs). The described stack includes deployable models, application code, development tools and partner support, intended to help developers move from an AI model toward an embedded application.
Microchip’s corporate AI overview presents local processing as useful where systems need low latency, privacy or real-time decisions, including industrial, automotive and consumer applications. These are the company’s stated advantages for edge processing, not a quantified comparison showing that edge AI is faster, more private or more efficient in every deployment. The best location for inference depends on the application’s response-time, connectivity, data-handling and compute requirements.
Developer assistance in MPLAB
In February 2025, Microchip launched the free MPLAB AI Coding Assistant for Visual Studio Code. It offers Microchip-specific chatbot assistance while developers write and debug embedded code. It complements the hardware and development ecosystem; the announcement does not make it a substitute for testing generated code on the target device or validating safety- and security-critical behavior.
Microchip’s AI data-center portfolio targets connectivity and storage
For data centers, Microchip’s April 2025 announcement described PCI Express (PCIe) switches and NVMe and RAID controllers, including hardware security. The listed products span PCIe Gen 3, Gen 4 and Gen 5, while Gen 6 and Gen 7 technologies were identified as in development. The distinction matters: the latter generations were development work, not a statement that those technologies were production-ready in that release.

They are distinct from the edge-AI MCUs and MPUs: data-center switches and controllers help connect or manage system components, while edge platforms support processing closer to a device or sensor. Microchip’s 2026 news archive also points to continuing work in PCIe Gen 6 storage, VectorBlox neural-network tooling, edge-AI sensor connectivity and power modules for AI data centers. An archive item establishes that the company reported work in an area, not by itself the product’s availability, performance or customer adoption.
How Microchip’s and TSMC’s AI roles differ
| Area | Microchip | TSMC |
|---|---|---|
| Manufacturing resilience | Expanded relationship for specialized 40nm capacity at JASM in Kumamoto, announced in April 2024; Microchip described it as a supply-chain resilience measure. | Manufacturing capacity is part of a broader foundry business; the cited company materials describe large-scale investment and process roadmaps. |
| Edge AI | Production-ready solutions built around MCUs and MPUs, with models, code, tools and partner support described in February 2026. | The cited TSMC announcements concern manufacturing technology and investment, rather than a Microchip-style embedded AI software stack. |
| Data-center infrastructure | PCIe switches, NVMe and RAID controllers, with hardware security; Gen 6 and Gen 7 technologies were listed as in development in April 2025. | Provides process technology and advanced-packaging capacity used by semiconductor customers; the cited material does not identify a specific Microchip data-center product made on a TSMC process. |
| Developer support | MPLAB AI Coding Assistant for Visual Studio Code launched free in February 2025. | The cited announcements focus on foundry processes, capacity and investment, not Microchip-specific embedded coding assistance. |
The comparison is about the roles described in the cited company announcements, not an exhaustive comparison of either company’s full product range. Microchip supplies chips, tools and infrastructure components; TSMC’s role is manufacturing technology and capacity for customers across the semiconductor industry.
TSMC’s capacity plans and process roadmap provide wider context
TSMC’s 2025 annual report, published in 2026, reported that revenue rose 35.9% year over year in U.S.-dollar terms in 2025 and said AI-related demand remained robust entering 2026. That figure is TSMC’s reported company-wide revenue growth; it does not measure Microchip’s growth or show that the Microchip–TSMC relationship caused the increase.
In March 2025, TSMC announced an intended additional $100 billion in U.S. investment, bringing its planned U.S. investment total to $165 billion. The expanded plan described three additional fabs, two advanced-packaging facilities and an R&D center. These are announced investment plans, not evidence that all facilities were already operating or that the full amount had been spent.

In April 2026, TSMC announced A13, a process it said would provide 6% area savings compared with A14. TSMC described A13’s design rules as backward-compatible and scheduled production for 2029. The area figure is the company’s comparison with A14; the announcement does not make A13 a currently available production process.

For an embedded-system team, Microchip’s announcements point to a combined hardware-and-software path for edge AI, plus a coding assistant and partner support. Selection still depends on the actual MCU or MPU, model requirements, memory, power budget, development workflow and the support needed for deployment; the cited releases do not provide a single benchmark that ranks these solutions against alternatives.
For data-center designers, Microchip’s stated PCIe, NVMe and RAID work concerns connectivity and storage, with security called out for the controllers. Product generation and availability matter: Gen 3 through Gen 5 were listed, while Gen 6 and Gen 7 were described as in development in the April 2025 release. For manufacturing planners, the JASM relationship adds a stated 40nm option in Japan, but no public figure in the cited materials quantifies its impact on customer deliveries.
Overall, Microchip’s AI advances are best understood as a portfolio spanning edge silicon, models, tools and data-center infrastructure—not as one new “AI chip.” TSMC supports that wider landscape through manufacturing capacity and process development. The companies’ statements establish the announced capabilities and plans, but do not independently quantify the partnership’s impact on Microchip’s growth or AI progress.
