The Intel EP4CE10E22A7N is a Cyclone IV E FPGA with 10,320 logic elements and 91 user I/O in a 144-EQFP package with an exposed pad. It's the mid-density workhorse of the Cyclone IV E line — enough fabric for a soft-core NIOS II, a modest state machine, or a bunch of peripheral bridging logic, but not a full video pipeline. The 423,936 bits of block RAM handle small FIFOs or coefficient lookup tables without burning logic cells.
91 I/O in a 144-EQFP — what that means for routing
The 144-EQFP (20x20 mm) with exposed pad gives 91 usable I/O. The rest are power, ground, configuration, and clock pins. Solder the exposed pad to a copper plane with a via array for thermal management.
Active lifecycle — no end-of-line pressure
Intel still supports the Cyclone IV E line with Quartus Prime software, and the device is widely stocked across the independent channel.
