5CGXBC7D7F31C8N - Cyclone V GX FPGA, 149.5K LE, 896-FBGA | Intel
The Intel (formerly Altera) 5CGXBC7D7F31C8N is a Cyclone® V GX field-programmable gate array (FPGA) with 149,500 logic elements, 7,880,704 bits of embedded memory, and 480 user I/O pins, housed in a 896-ball FineLine BGA (FBGA) package. Built on TSMC's 28 nm low-power process, it integrates up to 9 transceivers capable of 3.125 Gbps operation, hard PCI Express® Gen2 endpoints, and dedicated DSP blocks, making it suited for cost- and power-sensitive mid-range designs.
A field-programmable gate array (FPGA) is a semiconductor integrated circuit that can be reconfigured by the customer after manufacture to implement arbitrary digital logic. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs), distinct from fixed-function ASICs by their post-fabrication flexibility and from microcontroller units (MCUs) by their parallel, hardware-timed execution model. Within Intel's portfolio, the Cyclone V family is positioned as the low-power, cost-optimized series for high-volume applications such as industrial motor control, video bridging, and machine-to-machine connectivity.
Key features include 149,500 logic elements (LEs), 7,880,704 embedded memory bits (approximately 963 Kbits of M10K plus 1.46 Mbits of MLAB), 312 DSP blocks of 18x18 multipliers, nine full-duplex 3.125 Gbps transceivers, two hard PCI Express Gen2 x1/x2/x4 endpoints, and eight PLLs. The 5CGXBC7D7F31C8N speed grade 8 (commercial, -8C) variant supports core VCC of 1.1 V with hot-socketing capability and configuration via passive serial, fast passive parallel, JTAG, or encrypted bitstream using AES-256.
The Cyclone V GX architecture combines a fabric of adaptive logic modules (ALMs), dedicated block RAM, DSP slices, and hard IP for PCIe, memory controllers, and high-speed serial I/O. This heterogeneous structure lets designers implement protocol bridging, signal processing, and control logic in a single device without consuming fabric resources for functions that are hardened in silicon.
Typical applications include industrial Ethernet switching and fieldbus gateways, video broadcast and surveillance processing, PCIe endpoint cards, motor drive control loops, and low-cost wireless baseband preprocessing. The transceiver-rich 5CGXC7 die (F31 package, 31 mm × 31 mm body, 1.0 mm pitch) targets designs that previously required a more expensive Arria or Stratix device.
When designing with this part, plan power-rail sequencing for 1.1 V core, 2.5 V/3.3 V auxiliary, and 1.5 V transceiver supplies, and respect the 896-ball BGA layout with 4 or 6 PCB layers and microvia stackups. Quartus II / Quartus Prime software with device support file 5CGXFC7D6 is required for synthesis, place-and-route, and bitstream generation.
This page combines drop-in same-family alternatives, parameter-by-parameter comparison, and practical PCB design notes that complement, rather than duplicate, the device datasheet and ordering information.
