Product details
Frequently asked questions
What is the datasheet for EP4CE15E22I7?
The EP4CE15E22I7 is an Intel Cyclone IV E FPGA. The official datasheet is available from Intel under the Cyclone IV Device Handbook.
What voltage does EP4CE15E22I7 use?
Core supply voltage is 1.15 V to 1.25 V. I/O banks have separate VCCIO rails for interface voltage flexibility.
Can EP4CE15E22I7 replace EP4CE15E22C8?
The EP4CE15E22C8 is a commercial-temperature variant (0°C to 85°C typical) of the same die. The I7 suffix here is the industrial-grade version (-40°C to 100°C). Pin-compatible, same logic density — the difference is the temperature range.
