ST-E Will Have FD-SOI Based U8540: 35% Lower Power, Much Higher Frequencies
 

There's a close relationship between process technology and performance/power consumption, and it's about to get even more important in mobile. We've already seen that with the transition to 40nm and we will see that shortly with the transition to 28nm. Today ST-E announced its upcoming U8540 will use fully depleted silicon on insulator (FD-SOI) transistors to gain a performance and power advantage over the competition. As an example, AMD originally introduced SOI to its processors in the early 2000s as a way of decreasing power and increasing clock speeds. ST-E claims the move to FD-SOI will allow for much higher operating frequencies compared to the L8540, or much lower power at the same switching speed.

Integrated baseband clearly offers some advantages in the market, but a process technology advantage can be even more important...
