Altera has increased the density range of its 40nm Stratix IV E FPGAs to 820K logic elements (LEs).

The Stratix IV E range now features four devices ranging in density from 230K to 820K LEs. The EP4SE820 has 53% higher density than the EP4SE530 device.

There are 820K LEs and 650K registers, and 23.1Mbits of 600MHz embedded memory.

The array of 960 18x18 multipliers runs at up to 550MHz.

There are also 1,120 I/Os which support 1.25Gbit/s LVDS data rates.
