TI has created a single chip that integrates most of the computing functionality needed by a mobile phone. Putting the digital baseband, SRAM, logic, radio frequency (RF), power management and analogue functions on one piece of silicon will, TI says, make it cheaper and easier for manufacturers to build entry-level phones.
Typically, mobile phones contain one chip devoted to handling the RF, as well as other chips for other functions. A high-end phone might have a separate chip for polyphonic ringtones, for example. But these chips are only one part of the overall cost of manufacturing a phone, with the battery and screen also key factors.
Dean Bubley, founder of analyst firm Disruptive Analysis, believes that it could help to push the cost of making a basic mobile phone as low as $25 within a couple of years, which would mean handsets could actually be given away.
