ROHM's New4-wire Resistive Touch Panel Controller ICs Enhance Touch Sense Operability

Willich-Munchheide, (PresseBox) - ROHM Semiconductor recently started the mass production of its new BU210xx series of 4-wire resistive touch panel controller ICs. Providing a huge variety of package options, the new high-resolution ICs include a 8bit or 32bit CPU for 2-point gesture detection and a calibration function for enhanced flexibility and reliability. Automotive-grade types are available as well. Proprietary technology and compact design enable component reduction and easier, user-friendly operability such as gesture input when wearing gloves.

Although capacitive touch panels capable of multi-point detection are increasing in popularity, there is still much demand for lower cost resistive touch technology in digital cameras, car navigation systems, and other applications. The resistive touch method typically provides 1-point detection operation using a stylus/pen or for simple button selection. However, ROHM has successfully developed and mass-produced 2-point detection controller ICs that are market-proven and have been widely adopted in automotive applications such as displays for audio and car navigation systems.

Key Features of BU210xx ICs

- Compatible with 4-wire resistive touch panels
- Integrated CPU, capable of 2-point gesture detection
- No external parts are required
- Calibration function absorbs characteristics changes due to temperature, aging, and production variations
- Operation possible while wearing gloves or with fingernails

Availability:The product is available.
