WM9715CLGEFL/RV Product Details

The WM9715CLGEFL/RV is a highly integrated input / output device designed for mobile computing and communications. The device can connect directly to a 4-wire or 5-wire touchpanel, mono or stereo microphones, stereo headphones and a mono speaker, reducing total component count in the system. Additionally, phone input and output pins are provided for seamless integration with wireless communication devices. The WM9715CLGEFL/RV also offers up to four auxiliary ADC inputs for analog measurements such as temperature or light. To monitor the battery voltage in portable systems, the WM9715CLGEFL/RV has two uncommitted comparator inputs. All device functions are accessed and controlled through a single AC-Link interface compatible with the AC’97 standard (rev 2.2). Additionally, the WM9715CLGEFL/RV can generate interrupts to indicate pen down, pen up, availability of touchpanel data, low battery, and dead battery. The WM9715CLGEFL/RV operates at supply voltages from 1.8 to 3.6 Volts. Each section of the chip can be powered down under software control to save power. The device is available in a small leadless 7x7mm QFN package, ideal for use in hand-held portable systems.
