Ideal for Mobile Phones ROHM Develops World's Smallest
4-Mbps IrDA (FIR) Module Provided with Remote Control Function

ROHM has recently developed for mobile phones the RPM972-H14 infrared communications module with a remote control transmission function that conforms to the 4-Mbps fast-infrared (FIR) specifications of Infrared Data Association (IrDA). The sample shipment of the RPM972-H14 already started at a unit price of 300 yen, and the full-fledged mass production of the RPM972-H14 will start at ROHM ELECTRONICS DALIAN (China) in November 2006 at a monthly rate of 500,000 units.

Recently, compact electronic products represented by mobile phones have started incorporating IrDA's compact FIR communications function as a standard feature. In addition, mobile phones have been making progress toward multi-functionalization with the use of infrared rays (e.g., a remote control transmission function).

The RPM972-H14 as an IrDA module that ROHM recently developed is based on the RPM971-H14, added with a remote control transmission function. The RPM971-H14 is the world's smallest IrDA communications module of surface mounting type presently under mass production. Furthermore, the RPM972-H14 does not need an external resistor (3216 size), which was required for conventional modules in remote control mode, thus contributing to the liberalization and space saving of set designs.

· Features

1. No external resistance is required.
2. A compact model of surface mounting type for a 4-Mbps module (with a height of 2.2 mm).
3. Low power consumption (2.4 mW) while in standby mode.
4. By using the BU92004GU controller LSI, which was developed by ROHM, the RPM972-H14 supports Ir Simple specifications at higher speed.

ROHM has been making full use of unique manufacturing technology along with production technology developed in-house as well as design technology and device technology to develop IrDA modules in response to market needs ahead of others. ROHM will continue product development including product downsizing from customer-oriented viewpoints.
