A Milestone Unveiled at Semicon India 2025
At the Semicon India 2025 summit, India proudly unveiled Vikram-32 (officially VIKRAM3201), marking a foundational step toward semiconductor self-reliance. It was presented to Prime Minister Narendra Modi by Electronics & IT Minister Ashwini Vaishnaw, symbolizing India’s commitment to domestic chip design and production
Origins & Technical Lineage
- Design & Fabrication: Developed by Vikram Sarabhai Space Centre (VSSC) and fabricated at ISRO’s Semiconductor Laboratory (SCL) in Mohali using a 180 nm CMOS process
- Evolution: Builds upon the legacy of India’s 16-bit VIKRAM1601, which powered ISRO’s launch systems since 2009
- Companion Chip: Its sibling, KALPANA-3201, is a SPARC V8 RISC microprocessor developed simultaneously
Engineered for Space: Why Vikram-32 Matters
- 32-bit Architecture: Handles larger datasets and complex logic faster than 16-bit predecessors
- Floating-Point Support: Enables high-precision operations vital for navigation, telemetry, and mission control
- Custom Instruction Set (ISA): Tailored for aerospace tasks and optimization
- Ada Language Support: Leverages reliability in aerospace systems; C compiler development is underway for broader versatility
- In-House Toolchain: Includes compiler, assembler, linker, simulator, and IDE—fully developed within ISRO
Proven in Orbit
Vikram-32 was not just a concept—it’s flight-certified. It successfully operated aboard the PSLV-C60 mission’s Orbital Experimental Module (POEM-4), proving its reliability in the harshest space environments
The Broader Implication for India’s Chip Ecosystem
This launch follows the India Semiconductor Mission (2021) and marks rapid progress—India has moved from chip consumer to creator in just 3.5 years
The unveiling included not only the Vikram chip but also test chips from four government-approved projects, showcasing India’s growing innovation footprint
Prime Minister Modi lauded the moment as a leap toward technological sovereignty. He emphasized that “semiconductor chips are the ‘digital diamonds’ of the 21st century” and called for global collaboration to build India’s semiconductor future
Potential Impact: From Space to Strategic Industries
- Space & Defence: Engineered for extreme temperatures, vibration, and radiation—ideal for rockets and satellites
- Broader Applications: Its ruggedness makes it suitable for automotive electronics, energy systems, and aerospace avionics
