ML9073/ML9074 series RTC from Oki Electric

Oki Electric Industry Co. Ltd has announced a current real-time clock (RTC) that's said to have the world's lowest current consumption at 0.15?A. The ML9073/ML9074 series has 1.5-fold longer battery life than conventional chips, the company said.

Most devices including digital cameras, audio players, TVs and DVD recorders have a built-in RTC for their clock functions to keep accurate time even when the power is turned off. However, most RTCs are embedded in ASICs and MPUs as an IP and it is difficult to minimize current consumption because ASICs and MPUs use leading-edge processes. Thus, reducing current consumption when the power is turned off has been a challenge in mobile equipment that runs on small batteries such as button dry batteries.

"With these new ICs, we succeeded in lengthening the battery life and reducing the size of the battery and condenser," said Masahiko Morioka, president of silicon solutions company at Oki Electric Industry. "To contribute to bringing down our customer's product size, Oki will leverage its SOI-CMOS technology and enhance its product lineup with high-performance, low current power, low voltage characteristics."

Oki is providing samples of this product to makers of mobile and AV equipment that requires long operating time. Sample price is $1.68 each.
