EP4CGX50DF27I6N 概述
A Field-Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnects, embedded memory, and hardened functional blocks such as transceivers and PLLs. FPGAs sit at the top of the programmable-logic taxonomy (FPGA -> programmable logic -> digital IC -> semiconductor), enabling engineers to implement custom digital circuits, glue logic, DSP pipelines, and high-speed serial interfaces without committing to a mask-programmed ASIC. Cyclone IV GX further specializes this class by adding 3.125 Gbps multi-gigabit transceivers (MGTs) targeted at protocols such as PCIe Gen1, Gigabit Ethernet, Serial RapidIO, and CPRI at very low static power.
Key features of the EP4CGX50DF27I6N include up to 3.125 Gbps transceiver data rate, 8 transceiver channels, 49,888 logic elements, 2,502 Kbits of embedded RAM, 113 embedded 18x18 multipliers, four general-purpose PLLs, and 310 maximum user I/O pins. Transceiver channels support common serial standards including PCIe Gen1 x1/x2, Gigabit Ethernet, Serial RapidIO v1.3, and CPRI, while 3.3 V-tolerant LVTTL/LVCMOS and LVDS I/O accommodate mixed-voltage legacy buses. The device is offered in the industrial temperature grade (-40C to +100C junction), suiting outdoor, factory-floor, and uncontrolled-environment deployments.
The Cyclone IV GX architecture pairs the transceiver-rich I/O ring with a fine-grained logic fabric, dedicated 9-Kbit M9K memory blocks, and DSP block multipliers. The static power consumption is typically below 1 W for most designs because the 60 nm low-power (LP) process minimizes leakage. Configuration is supported through Active Serial (AS), Passive Serial (PS), Fast Passive Parallel (FPP), and JTAG modes, with built-in optional 16-bit CRC and 128-bit AES encryption for design security.
Typical applications include industrial motor control and drive interfaces, low-cost PCIe endpoint cards, video surveillance and broadcast bridging, software-defined radio front-ends, and factory-automation backplanes. The combination of low cost, integrated transceivers, and small FBGA footprint makes the EP4CGX50 family especially popular in volume production designs.
When designing with this part, choose the F27 (672-ball FBGA) variant when higher I/O count and maximum transceiver availability are required; the F23 (484-ball) variant is the lower-pin-count alternative in the same family. Designers should follow Intel/Altera PCB guidelines for FBGA fan-out, signal-integrity simulation of transceiver channels, and reference decoupling on each VCC/VCCIO/VCCPT/VCCA supply rail.
This page synthesizes distributor pricing, verified drop-in alternatives from the same Cyclone IV GX family, and practical design notes not found in the manufacturer datasheet, providing an at-a-glance engineering reference for procurement and design-in decisions.

设计说明
The 672-ball FBGA (F27) package requires a 1.0 mm pitch BGA footprint with at least 4 layers of PCB stack-up for signal breakout. Intel recommends an 8-layer stack-up with dedicated ground and power planes for noise-sensitive designs. Via-in-pad with filled-and-capped microvias is strongly recommended for transceiver channel routing; blind/buried vias help route escape signals from inner balls. Follow the Altera/Intel Cyclone IV GX Hardware Reference Manual fan-out and stack-up guidelines for the F27 package.
Each multi-gigabit transceiver channel must be routed as a 100 ohm differential pair with matched length to within +/-5 mil (0.13 mm) for 3.125 Gbps operation. Use controlled-impedance PCB traces (typically stripline between ground planes for inner layers or coplanar waveguide with ground pour for outer layers). AC-coupling capacitors (typically 100 nF) are required between the FPGA and external connectors or serdes devices. Reference-clock inputs should be routed with 50 ohm single-ended or 100 ohm differential impedance and isolated from data lines by ground vias.
The Cyclone IV GX EP4CGX50 requires four distinct supply rails: VCCINT (1.2 V core), VCCIO (1.2 V to 3.3 V I/O banks), VCCPT (1.2 V for transceiver PLL analog), and VCCA (2.5 V for transceiver analog). Each rail requires bulk decoupling of 100 uF or larger plus 0.1 uF and 0.01 uF ceramic decoupling placed within 100 mils of each supply pin. The POR (power-on-reset) supply sequence requires VCCINT and VCCPT to ramp before VCCIO; failure to observe this sequence may damage the device or cause configuration errors.
Estimated: at typical 1.2 V core with 50% logic utilization and 4 active transceivers at 3.125 Gbps, the EP4CGX50 dissipates approximately 2.0 to 3.5 W. With F27 package theta_JA around 14 C/W for a JEDEC-compliant 4-layer board with minimal airflow, junction-to-ambient rise is roughly 28C to 49C, leaving 51C to 72C of margin to the industrial 100C junction limit. Designs running all 8 transceivers at full rate should consider thermal vias under the FBGA thermal pad and at least 200 LFM of forced airflow.
Do not leave transceiver reference-clock inputs floating; always drive them with a clean 100 MHz or 125 MHz LVDS reference. MSEL pins must be hardwired to the correct logic level for the desired configuration mode (AS, PS, FPP, or JTAG) before power-up. Configuration pins nCONFIG, nSTATUS, and CONF_DONE must be pulled up to VCCIO through 10 kohm resistors. JTAG chain integrity should be verified with the Quartus Programmer before attempting any boundary-scan or in-system programming.
