Made‑in‑India, Space‑Grade Chip Demonstrates India’s Leap in Semiconductor Self‑Reliance
- At Semicon India 2025 in Delhi, India revealed its first fully indigenous 32‑bit microprocessor, Vikram 3201, developed by ISRO’s Semiconductor Laboratory.
- The chip was showcased by Electronics & IT Minister Ashwini Vaishnaw to Prime Minister Narendra Modi, who hailed microprocessors as the “digital diamonds” of the modern age.
Key Features of Vikram 3201
- Indigenous Design & Fabrication
Clearly a milestone in Aatmanirbhar Bharat, the chip—designed by VSSC and fabricated at SCL using 180 nm CMOS technology—is tailor-made for space missions. - Built for Harsh Conditions
Capable of operating between –55 °C and +125 °C, it withstands extreme temperature swings, radiation, and vibration. - 32‑Bit Architecture & Advanced Capabilities
Supports 64‑bit floating‑point operations, custom Instruction Set Architecture (ISA), Ada programming language, and on‑chip 1553B bus interfaces for robust control logic. - Complete In‑House Ecosystem
ISRO has developed the full software stack—including Ada compiler, assembler, linker, simulator, IDE—and a C compiler is underway for wider applicability. - Tested in Space
The chip has been validated in orbit aboard PSLV‑C60’s POEM‑4 module, affirming its reliability.
Why This Matters
| Aspect | Significance |
|---|---|
