[Altera]
Altera’s new Cyclone® IV FPGA device family extends the Cyclone
FPGA series leadership in providing the market’s lowest-cost,
lowest-power FPGAs, now with a transceiver variant. Cyclone IV
devices are targeted to high-volume, cost-sensitive applications,
enabling system designers to meet increasing bandwidth requirements
while lowering costs.
Cyclone IV Device Family Features
The Cyclone IV device family offers the following features:
