Earlier this week Infineon showed off a 65nm handset chip which features more than 30 million transistors on a space of just 33 square milimeters:
The company said the chip puts more than 30 million transistors on a space of just 33mm2 and proves that Infineon is able to produce such major digital and analog circuitry in handsets as MCU/DSP cores, storage and analog/mixed-signal in 65nm technology to operate with high reliability. This space-saving technology was also used to manufacture high-frequency circuits for the first time, the company claimed.
It should be ready for launch by the end of this year. More details over at DigiTimes.
