What the EP4CE40F29C9L brings to the board
The Intel EP4CE40F29C9L is a Cyclone IV E FPGA with 39600 logic elements and 532 I/O in a 780-FBGA package. It's a medium-density gate array for designs that need a lot of user I/O — think display controllers, video processing pipelines, or parallel bus interfaces where the pin count drives the board layout. The 780-ball BGA (29x29 mm) means a multilayer PCB; you're not routing this on a two-layer board.
Core supply tolerance — why it matters for your power rail
The core voltage range is 0.97 V to 1.03 V. The 1.15 V supply on the EP4CE75 peer is more forgiving.
Temperature grade and deployment environment
Rated for 0°C to 85°C (TJ) — commercial temperature grade. If the board needs to live in a hot factory hall without air conditioning, look at the industrial-grade Cyclone IV E variants.
Memory and logic fabric
1161216 bits of embedded RAM and 2475 LABs/CLBs. The logic fabric at 39600 elements sits between the entry-level Cyclone IV and the larger EP4CE75.
Lifecycle and sourcing posture
The EP4CE40F29C9L carries an Active lifecycle status. No end-of-life notice, no last-time-buy clock ticking. That means Intel is still producing it, and the supply chain can support new designs and production runs without obsolescence risk. For a BOM freeze, this part is a safe bet through the next several years.
