Intel continues to manufacture this density and package variant, so there is no last-time-buy clock running. New designs can proceed without an immediate obsolescence contingency, though Cyclone IV E is a mature family — always check the latest PCN for any future transition.
Package and mounting — 144-EQFP with exposed pad
The pad is electrically connected to GND; a proper via array under the pad pulls heat into the board plane. The Tray shipping format is typical for production pick-and-place; if you need Tape & Reel for high-volume reels, verify the alternate ordering code suffix with your distributor.
