Does your ASIC design require the lowest leakage and smallest area possible? Do you want to adopt the FinFET technology but are concerned about the expensive wafer cost? The TSMC 22nm process offers a compelling option. We are seeing many Arm partners who have used processes in 28nm, 40nm, and above, now migrating to 22nm to achieve lower leakage and a smaller area to maintain or even boost the desired performance.
The TSMC 22nm technology was developed based on TSMC’s industry-leading 28nm process, a preferred foundry solution for many different market segments in terms of its performance, power, and area scaling. However, some IC designers are looking for an economical way to meet the requirements for performance boost and lower supply voltage in applications such as digital TVs, set-up boxes, smartphones, and consumer products. For such IC designs, TSMC 22nm is the best way to increase performance and reduce power cost-effectively, which provides significant area reduction, speed gain, and power reduction compared to 28nm process.
One of Arm’s partners, Ambiq Micro, a leading licensor of wireless connectivity and smart sensing technologies, has been working with Arm to upgrade from 40nm to 22nm. Ambiq used Arm IP, including Cortex-M, Crypto, CoreSight SoC-400, ETM, TSMC 22ULL memories, and TGO libraries to achieve subthreshold leakage with embedded security. Some of the benefits of the Arm solution included:
Based on Ambiq’s feedback, Arm Artisan memory compilers helped shrink area by 5 percent and reduce leakage by 4 percent compared to competitor IP, while meeting the same performance criteria.
TSMC supports Artisan memory compilers for TSMC 22nm ULP and ULL process technologies. These compilers are optimized for low-leakage and low-power requirements.
