Introduction: A Historic Leap Forward
India has entered a new era of technology with the launch of Vikram-32 (VIKRAM3201), the nation’s first indigenously developed 32-bit semiconductor processor. Revealed at Semicon India 2025, this chip not only enhances India’s capabilities in space technology but also represents a revolutionary step towards semiconductor self-reliance.
Unlike earlier generations that relied on foreign imports, Vikram-32 is a homegrown achievement, reflecting India’s determination to build a trusted, indigenous semiconductor ecosystem.
The Story Behind Vikram-32
Developed at the Semiconductor Laboratory (SCL), Chandigarh, under the leadership of ISRO and the Vikram Sarabhai Space Centre (VSSC), Vikram-32 builds on the legacy of the 16-bit Vikram1601 chip introduced in 2009.
What makes it special is its fabrication using 180nm CMOS technology, entirely within India. This not only showcases India’s chipmaking expertise but also sets the stage for advanced processors in the future.

Why Vikram-32 Matters for India
Semiconductors are the foundation of modern electronics. From smartphones to satellites, they define global competitiveness. For decades, India depended on imports, but with Vikram-32, the country demonstrates the ability to design, fabricate, and deploy chips independently.
The benefits extend beyond space missions:
-
Defence applications – secure and indigenous technology
-
Avionics and aerospace – high-reliability navigation
-
Automotive and EVs – rugged electronics for new mobility solutions
-
Industrial and energy systems – precision control in critical sectors
By localizing chip production, India strengthens its digital sovereignty and economic resilience.
Part of a Larger Semiconductor Vision
Vikram-32 is not a standalone achievement—it’s a cornerstone of the India Semiconductor Mission. At Semicon India 2025, PM Narendra Modi praised the development as a moment of national pride and urged the industry to go beyond design into fabrication and packaging.
The government has already approved ₹1.6 lakh crore in semiconductor projects, paving the way for multiple fabs, R&D centers, and chip design startups. Initiatives like the Design Linked Incentive (DLI) scheme are also fueling innovation in semiconductor design.
