This product line has merged power saving & high bandwidth in one. Potato Semiconductor Corporation has integrated its low noise & high frequency technology into Bus Switch products. The maximum data transfer rate can be as high as 3.5Gbps. More importantly, those bus switch products consume extremely low power (0.1uA type).
Unlike many of the current source designed Bus Switch ICs that require 800uA to 2000uA static current, all of the Potato Chips are designed without current sources. The Bus switch is an electronics switch device without driving capability. It is not suppose to drain any electronics current.
Potato Semiconductor applied its technology to 74-series logic ICs, claiming running speeds of five to seven times faster than existing 74-series ICs. 74-series ICs occupy a very important role in the semiconductor industry. Their circuitry is the basis of all logic ICs and represents the first standardised IC series in electrical engineering. These types have been widely used in appliances, computers and many other electric and electronic products for over 40 years, a popularity that continues today. However, there has been no performance breakthrough for decades because of inherent noise problems.
Potato claimed to solve this problem, meaning that noise generated from high frequency operating environments can be effectively eliminated and the performance of ICs can be dramatically enhanced.
Richard Kao, the CEO of Potato Semi, stated that while 74 series ICs are basic and standard IC products and all main IC manufacturers have this product line, until now, none of them has been able to make technical breakthroughs in performance.
After careful research, Kao finally determined what he believed to be the root cause of noise in these types of logic circuits and as a result decided to abandon primitive IC design algorithms, deciding instead to develop a completely new theory, ushering in a new IC design algorithm.
In TTL/CMOS technology, high frequency amounts to high noise levels. By eliminating noise, an IC's performance can reach the upper limit of its manufacturing process. Using 0,35 ?m CMOS as an example, the operating frequency of ICs based on old design algorithms is about 150 MHz, while Potato's patented technology delivers devices that perform at speeds greater than 1 GHz, which is the upper limit of the 0,35 ?m CMOS process.
