Renesas Electronics of Japan Develops Next-Generation Semiconductor Chip Energy Saving Technology

Renesas Electronics has successfully developed next-generation large-scale integrated circuits that can drastically reduce power consumption, and data transmission technology that does not require batteries, and it is expected to be put into use after 2 to 3 years. Renesas's built-in monitoring circuitry in the semiconductor chip can accurately control the operation of the chip and ensure that the chip operates at maximum efficiency, thereby saving unnecessary power consumption and saving up to 27% of electricity. It is expected that it will take 2 to 3 years Power consumption is reduced to 50% of existing products, and if it is mounted on a smart phone, battery life will increase by 20 to 30%.

Of course, the monitoring circuit is not Renesas Technology's first technology, but due to the high cost, it can not be widely used in all semiconductors, so it is usually only used for high-priced products such as personal computers, but the general-purpose monitoring circuit developed by Renesas. Can be applied to a variety of semiconductors, have positive help for cost control.

Another new invention is the use of sensors to convert the energy of the surrounding electromagnetic waves into electricity for data transmission, so that there is no need to rely on batteries to provide electricity. For example, to send a thermometer-measured value to a mobile phone, the built-in sensor of the thermometer can use the electromagnetic wave generated by the nearby wireless LAN access point to generate a current, and then the sensor generates electricity to transmit the measurement result of the thermometer. The power consumption is only Need one thousandth of usual.

The sensor can also recover environmental electromagnetic waves from TVs and mobile phone base stations and convert them into usable power. If this sensory technology can be combined with a smart phone in the future, even if the parents are separated from the children, they can still know the child's body temperature through the mobile phone and keep abreast of the child's physical condition at any time.

Environmental protection is an inevitable trend in the future, and the demand for semiconductor power-saving performance in all sectors will only increase. The first minister of Renesas Research, Mizuno Masaki, said that energy saving has to start from a small place, and each chip is the key. As long as the semiconductor industry does not abandon the highest principle of “energy saving,” the machine performance will be upgraded to the next level. Finally, the ultimate goal of zero power consumption.
