Touch Sensor Controller Converts Capacitance To Digital Data

Created by ATLab of South Korea, the company is distributing the FMA1127 touch sensor controller that converts capacitance generated by the human body and conductive touch pad to digital data with no analog processing. The capacitive touch controller is ideally suitable for mobile phones, PDAs, remote controllers, multimedia players, and other mobile devices. The FMA1127 operates with a voltage range of 2.5V to 5.5V and at temperatures between -35?C and +85?C. Current requirements are less than 0.15 mA and response time is 0.2 ms. A total of 8 kV ESD protection is provided for the chip/contact pad and 15 kV for system/air. No ground is required for the touch pad, and no external clock source is needed. Equipped with an I2C interface, the FMA1127 automatically adjusts sensor sensitivity based on the operating environment. Available now in a variety of packages that support as many as 12 sensor input channels and 12 DIOs, pricing begins at $1.40 each/10,000. FUJITSU MICROELECTRONICS AMERICA INC., Sunnyvale, CA. (408) 737-5600.
