About – L & L Semiconductors

Manufactured Chips

Our chips are manufactured at three FABs. Global Foundries, IHP Semiconductor and Skywater Semiconductor. Technology nodes are 180nm and 130 nm. We have manufactured digital as well as analog chips using open-source tools, PDKs and methodology.

Our designs include 16-bit microprocessor, SPI, I2C, UART, VGA, PWM, SRAM, ROM in digital segment. We have designed PLL, ADC, DAC, VGA, OpAmp in analog domain as well. We offer all these as a packed SoC. This SoC is equivalent to any low-cost embedded systems available in the market.

Open-Source Semiconductor

The era of COVID has changed the world. The semiconductor industry has also changed. The open-source electronic design automation tools are now equivalent to the commercial tools. We use them extensively to design chips.

With the support from Google few FABs have made their process design kits open. Now people can download and use them without signing and document. Even there is no need to write mails to anybody. We manufacture our designs with those FABs. We have done six tapeouts so far.

Accomplished work.

We have done six tapeouts with 13 IPs so far. The die size varies from 1 mm² to 10 mm². We are constantly working on new designs. And we are taping our chip twice a year. Feature rich SoCs are expected soon.

We are the only company in India who has seen the evolution of open-source ecosystem. We have gone through the full circle of tools, methodology, design, development and manufacturing. With this extensive knowledge we are providing the service for open-source chip design and fabrication. Visit our Services page

Tapeouts

Our Brilliant Team.

We have a great pool of young engineers. Over the years they have joined and left. Skanda, Spoorthi, Priyanshu, Muzammil, Divya, Sairam, Kamalesh, Deeksha.

Our engineers design the IPs. They do not work on the designs that come from overseas. They do not verify the designs from other country. They do not fix bug which is created by others. They create their own design and verify, debug their own designs.
