Logic density and I/O budget for BOM fit
The EP4CE6F17C9LN delivers 6272 logic elements across 392 LABs/CLBs, with 179 user I/O brought out to the 256-LBGA package. This places it at the entry point of the Cyclone IV E family — sufficient for glue logic, sensor fusion, or a soft-core MCU, but not for a full video pipeline or multi-gigabit transceiver design. On-chip block RAM totals 276480 bits, enough for a moderate FIFO buffer or a small coefficient lookup table. Designs that exceed this must budget for external SRAM or SDRAM on the PCB, consuming I/O and board area.
Package, supply, and temperature grade
Housed in a 256-ball FBGA (17x17 mm body), the EP4CE6F17C9LN requires a multi-layer PCB with controlled-impedance traces for any high-speed I/O. The 0.97 V to 1.03 V core supply demands a tight-regulation rail — a 1.0 V LDO or switching regulator with ±3% accuracy is typical. The 179 I/O banks run on separate VCCIO rails, configurable per bank from 1.2 V to 3.3 V. Rated for the commercial temperature range (0°C to 85°C junction), this variant is suited for controlled indoor environments — telecom cabinets, industrial controllers, or test equipment. It is not qualified for automotive or extended industrial ambient above 85°C.
