ISRO & SCL Develop 32-bit Microprocessors for Space Applications
In a significant breakthrough, the Indian Space Research Organisation (ISRO) and the Semiconductor Laboratory in Chandigarh have jointly developed two 32-bit microprocessors, VIKRAM3201 and KALPANA3201, specifically designed for space applications. These microprocessors are a testament to India’s growing capabilities in designing and developing complex electronic systems for space exploration.
The VIKRAM3201 microprocessor is a remarkable achievement, as it is the first fully “Make-in-India” 32-bit microprocessor that has been qualified for use in the harsh environmental conditions of launch vehicles. This development is a significant milestone for India’s space program, as it demonstrates the country’s ability to design and manufacture sophisticated electronic systems for space applications.
The Need for Customized Microprocessors
Space applications require customized microprocessors that can withstand the extreme conditions of launch vehicles, such as high temperatures, radiation, and vibrations. Conventional microprocessors are not designed to operate in such harsh environments, which makes it essential to develop specialized microprocessors for space applications.
The VIKRAM3201 and KALPANA3201 microprocessors are designed to meet the specific requirements of space applications. They have been developed to operate in the range of -20°C to 100°C, and can withstand radiation levels of up to 100 krad (SI). They also have a high level of immunity to electrical noise and can operate with a power supply of 3.3V.
Features and Capabilities
The VIKRAM3201 microprocessor has a clock speed of 50 MHz and a bus speed of 20 MHz. It has a 32-bit architecture, with a 32-bit data bus and a 32-bit address bus. It has a total of 128 KB of on-chip memory, including 64 KB of RAM and 64 KB of ROM.
The KALPANA3201 microprocessor has a clock speed of 25 MHz and a bus speed of 10 MHz. It also has a 32-bit architecture, with a 32-bit data bus and a 32-bit address bus. It has a total of 64 KB of on-chip memory, including 32 KB of RAM and 32 KB of ROM.
Both microprocessors have a high level of integration, with built-in peripherals such as UART, SPI, I2C, and timers. They also have a high level of security, with built-in encryption and decryption capabilities.
Advantages
The VIKRAM3201 and KALPANA3201 microprocessors offer several advantages over conventional microprocessors. They are designed to operate in extreme temperatures, making them ideal for use in space applications. They are also highly reliable, with a high level of immunity to radiation and electrical noise.
