What this Cyclone IV E FPGA brings to the board
The Altera EP4CE15E22C9LN is a Cyclone® IV E FPGA with 15408 logic elements and 516096 bits of embedded RAM, packaged in a 144-EQFP with 81 user I/Os. The commercial temperature range (0°C to 85°C) suits indoor equipment with controlled ambient.
15,408 logic elements — what that means for your design
The 15408 logic elements place this part between the smaller EP4CE6 (6272 LEs) and the EP4CE10 (10320 LEs) in the same family. The 516096 bits of block RAM support moderate FIFO depths or small frame buffers.
81 I/Os in a 144-EQFP — routing and interface limits
The 144-EQFP (20x20 mm, exposed pad) gives you 81 usable I/Os. If your application needs more I/O, the EP4CE10 or EP4CE6 variants offer more flexibility but have fewer logic elements.
