Despite reports of low yields on TSMC’s 28nm process, Xilinx says it is having the fastest new-node product roll-out in its history having shipped four of its five 28nm product families in 11 months.
That is half the time it took to roll out initial devices in two product families at 40nm.
TSMC says that the 28nm ramp is 3x faster than the 40nm ramp.
Though 40nm was, of course, a dog of a node.
Xilinx is using TSMC’s HPL process. Its rival Altera is using TSMC’s LP and HP processes.
TSMC's wireless clients are using the LP process.
Xilinx says it has taped out more than 10 devices and expects to be sampling all members of its 28nm portfolio by mid-2012.
‘TSMC's HPL process has given Xilinx a tremendous time-to-market advantage and is providing yields in line with the company's aggressive roadmap and better than previous generations,’ states Xilinx.
