Description
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. Built on an
optimized low-power process, the Cyclone IV device family offers the following two variants:
¦ Cyclone IV GX—lowest power and lowest cost FPGAs with 3.125 Gbps
transceivers
- Cyclone IV E devices are offered in core voltage of 1.0 V and 1.2 V.
