EP4CGX75CF23C8 Overview
A Field Programmable Gate Array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs belong to the broader category of programmable logic devices (PLDs), which sit between fixed-function ASICs and software-driven processors in the silicon design hierarchy. Cyclone IV GX FPGAs combine general-purpose logic fabric with embedded transceivers, allowing a single chip to implement glue logic, parallel bridges, video processing, and low-speed serial protocols.
Key features of the EP4CGX75CF23C8 include 4,620 Configurable Logic Blocks (CLBs), 4,257,792 bits of embedded RAM (approximately 4.05 Mbit when measured in M9K blocks), eight 3.125 Gbps transceivers, two hard PCIe Gen1 IP cores, and 290 general-purpose I/O pins supporting LVDS, SSTL, and LVCMOS standards. The 484-ball FBGA package measures 23 x 23 mm with a 1.0 mm ball pitch, enabling high-density board designs while remaining compatible with standard PCB manufacturing processes.
The Cyclone IV GX architecture pairs a 60 nm low-power core fabric with dedicated transceiver circuitry, allowing designers to build PCI Express endpoints, multi-gigabit transceivers (MGTs), and parallel video pipelines without external PHY devices. Static power is reduced by approximately 25% compared to the prior Cyclone III generation, enabling fan-less industrial designs.
Typical applications include industrial machine vision, broadcast video switching, low-cost PCI Express endpoint cards, motor and motion control, and protocol bridging for serial backplanes. The combination of integrated transceivers, on-chip PCIe, and low static power makes this device attractive for volume, cost-sensitive designs that previously required discrete ASSPs.
When designing with this device, ensure Quartus II (13.0 or later 13.x) is used for synthesis, place-and-route, and timing closure, because newer Quartus versions do not include legacy Cyclone IV support. Pin assignments must use the F23 (484-ball) package symbol; signals on the F484 and F23 packages are not interchangeable.

Key Differentiators
- Most cost-effective high-I/O option in the Cyclone IV GX F23 package family (vs EP4CGX110CF23C8N)
- Speed grade 8 offers the lowest commercial price point in the F23 footprint (vs EP4CGX75CF23C7N)
- 8 integrated 3.125 Gbps transceivers remove the need for external PHY silicon (vs Cyclone IV E (non-GX) family)
Design Notes
Place 100 nF decoupling capacitors on every VCCINT and VCCA power pin within 2 mm of the BGA ball, and add 10 uF bulk capacitors near the four package corners. The transceiver analog supply (VCCH_GXB) must be filtered with a ferrite bead and decoupled with 0.1 uF and 10 uF capacitors to keep jitter below the 3.125 Gbps Tx/Rx spec. Source: Cyclone IV GX PCB layout guidelines.
Route each 3.125 Gbps transceiver differential pair as a 100-ohm differential microstrip or stripline, length-matched within 150 mils of the paired lane. Keep at least 3W (3x dielectric thickness) spacing between adjacent transceiver pairs and at least 5W spacing to all other signals. PCIe transmit and receive pairs should target 85-ohm differential impedance when using the AC-coupling capacitors specified in the device handbook.
Power sequencing requires VCCINT (1.2 V core) to ramp before or simultaneously with VCCA (2.5 V analog PLL supply). VCCPD (3.3 V or 2.5 V I/O pre-driver) must be present before any I/O bank voltage. Use a power management IC with monotonic, tracked ramp; never allow VCCINT to back-power through an I/O. Estimated VCCINT current at 100% toggle on 73,920 LEs is approximately 1.2 A; verify with the PowerPlay early power estimator in Quartus II.
Do not confuse the F23 (484-ball FBGA) package with the F484 (484-ball FBGA) used by the Cyclone III family: although the package body is identical, the ball map differs and Cyclone III bitstreams will not load. Always generate the pinout from the EP4CGX75 F23 symbol in Quartus II 13.x. Also, the trailing 'N' denotes lead-free terminal finish only; both N and non-N variants share the same silicon die and OPN ordering logic.
Estimated: at 1.2 V core and 100% resource utilization, the dynamic power of the EP4CGX75CF23C8 is approximately 3-4 W; combined with 8 transceivers at 3.125 Gbps each drawing ~120 mW, total power budget is in the 5-7 W range. The 484-ball FBGA has a theta_JA around 14 C/W with 4 thermal vias in the package center; design a continuous ground plane beneath the device and consider a small 10x10 mm heatsink if the enclosure is sealed and ambient is above 60C.
Compliance Information
RoHS-compliant per Intel/Altera product page. Commercial temperature grade 0C to +85C; not AEC-Q100 qualified for automotive. Trailing 'N' suffix denotes lead-free terminal finish and is the recommended RoHS-compliant ordering code.
