Active lifecycle — no LTB, no allocation signal yet
The EP4CE10E22C9L is listed as Active with no PCN or EOL notice. It remains in the standard ordering window through franchised distribution.
Package and I/O — 144-EQFP with 91 usable pins
The 144-EQFP (20x20 mm) leaves roughly half the pins for user I/O after power, ground, configuration, and dedicated clocks. That's typical for this density tier — you get 91 I/O, enough for a parallel bus, a handful of serial interfaces, and some discrete control lines. The exposed pad helps thermal transfer; make sure your PCB footprint includes a thermal via array under the pad to keep junction temperature below 85°C in still air.
