Vikram-32: India’s First Indigenous 32-Bit Microprocessor

1. Introduction

  • Vikram-32, officially named VIKRAM3201, is India’s first fully indigenous 32-bit microprocessor.

·        Designed with precision at ISRO’s VSSC and crafted at the Semiconductor Laboratory (SCL) in Mohali.

·        Marking a historic moment, the indigenous advancement was showcased at Semicon India 2025 and presented in person to Prime Minister Narendra Modi.


2. Significance of the Chip

  • Marks a milestone in India’s semiconductor self-reliance.
  • Reduces dependency on imported chips for space and defense applications.
  • Demonstrates India’s ability to move from being a consumer to a creator in the global semiconductor ecosystem.

3. Technical Specifications

  • Architecture: 32-bit with both fixed-point and IEEE-754 floating-point support.
  • Speed: Operates around 100 MHz.
  • Power Consumption: Less than 500 mW.
  • Voltage: Works on 3.3 V supply with very low quiescent current (<10 mA).
  • Operating Range: Reliable from –55 °C to +125 °C.
  • Packaging: Ceramic PGA package with 181 pins.
  • Process Technology: Fabricated using 180 nm CMOS technology.

4. Software & Programming

  • Supports Ada programming language; C compiler under development.
  • Complete toolchain (compiler, assembler, simulator) developed in-house by ISRO.
  • Uses a custom instruction set architecture (ISA) tailored for aerospace needs.

5. Reliability & Validation

·        Built to survive extreme radiation and temperature conditions of space.

  • Successfully validated in space aboard PSLV-C60 mission.
  • Successor to the VIKRAM1601 (16-bit) processor that has been in use since 2009.

6. Applications

  • Space Missions: Guidance, navigation, and control systems for satellites and launch vehicles.
  • Defense: Reliable electronics for secure communication and missile systems.
  • Aerospace: Advanced avionics requiring rugged computing power.
  • Automotive & Energy: Future potential for high-reliability systems.

7. Global Context

  • While commercial chips use 3 nm to 5 nm nodes, Vikram-32 uses 180 nm, which is still the preferred standard for space-grade chips due to durability and radiation resistance.
  • Comparable to established global space processors like RAD750 (USA) and LEON (Europe).

8. Strategic Importance

  • Boosts India’s semiconductor mission and reduces technological dependency.
  • Strengthens Atmanirbhar Bharat (self-reliant India) in critical technologies.
  • Positions India alongside major players in space-grade semiconductors.

9. Future Outlook

·        Anticipated to develop into more potent versions for intricate space travel.

  • Potential expansion into commercial and industrial sectors beyond ISRO.
  • Symbolizes the beginning of India’s journey into high-end semiconductor innovation.

In Summary:
More than just another semiconductor, Vikram-32 reflects India’s journey toward autonomy and technological leadership. Its validated performance in space, indigenous engineering, and future scalability firmly place the country alongside global players.
