EP4CE30F23C8N Datasheet, Pinout, Equivalents, and Specs

The EP4CE30F23C8N is a mid-to-high density FPGA from Intel's (formerly Altera) Cyclone IV E family, fabricated on a 60 nm low-power process with a 1.2 V core supply. It integrates 28,848 logic elements, 594 Kbit of embedded M9K SRAM, 66 embedded 18×18 multipliers, and 4 PLLs in a 484-pin FineLine BGA package. With 328 user I/O pins, speed grade C8, and commercial-grade operation (0 °C to 85 °C), the EP4CE30F23C8N is the FPGA at the heart of the ALINX AX530 development board — targeting industrial automation, video processing, communications protocol bridging, and embedded DSP applications where higher logic density and extensive I/O connectivity are required.

1. What Is the EP4CE30F23C8N?

The EP4CE30F23C8N belongs to the Cyclone IV E product line — Intel's 60 nm, low-power FPGA family designed for cost-sensitive, high-volume applications. The “EP4CE30” designation indicates the Cyclone IV E die with approximately 28,848 logic elements, “F23” specifies the 484-FBGA package (23 × 23 mm body), “C8” denotes the slowest commercial speed grade, and the trailing “N” confirms lead-free (RoHS-compliant) packaging.

Compared to smaller members of the family such as the EP4CE15F23C8N (15,408 LEs) or the EP4CE10E22C8N (10,320 LEs), the EP4CE30 nearly doubles the logic capacity while adding more embedded RAM and multiplier resources. This makes it suitable for designs that outgrow mid-range Cyclone IV E devices but do not yet require the density or cost of a Cyclone V or Cyclone 10 GX migration.

The 66 M9K embedded memory blocks provide 594 Kbit of dual-port SRAM, each configurable as single-port RAM, simple dual-port, true dual-port RAM, ROM, or FIFO buffers operating at up to 260 MHz. The 66 embedded 18×18 multipliers support high-throughput DSP operations, with each block capable of implementing one 18×18 or two independent 9×9 multiplications. Four general-purpose PLLs deliver clock synthesis, multiplication, division, and phase shifting across 20 global clock networks.

2. Pinout Configuration and Packaging

The EP4CE30F23C8N is housed in a 484-pin FineLine BGA (FBGA) package with a 23 × 23 mm body and 1.0 mm ball pitch. The BGA uses a 22 × 22 ball grid array with depopulated corners. Of the 484 balls, 328 are available as user I/O, distributed across eight independent I/O banks — significantly more than the four banks available in smaller Cyclone IV E packages.

Each I/O bank supports an independent V_CCIO supply rail, enabling mixed-voltage interfacing within a single device. The I/O element (IOE) architecture supports multiple single-ended standards — LVTTL (3.3 V), LVCMOS (1.2 V to 3.3 V), SSTL-2, SSTL-18, and HSTL — along with differential LVDS at up to 640 Mbps, mini-LVDS, RSDS, LVPECL, BLVDS, and PPDS. PCI and PCI-X compliance is supported for 33 MHz and 66 MHz bus operation.

The F23 package provides dedicated clock input pins on all four sides of the die that connect directly to the 20 global clock networks and 4 PLLs. Configuration pins support Active Serial (AS) mode using an EPCS64 or EPCS128 serial configuration device, Passive Serial (PS), Fast Passive Parallel (FPP), and JTAG via the IEEE 1149.1 boundary-scan port. The MSEL[1:0] pins determine the configuration scheme at power-up. BGA ball assignments are documented in the Cyclone IV E Pin-Out Files available from Intel's download center.

4. Typical Applications and Circuit Considerations

The EP4CE30F23C8N is designed for applications requiring high programmable logic density with extensive I/O connectivity and low power consumption. Its combination of nearly 29,000 LEs, 66 multipliers, 594 Kbit embedded RAM, and 328 user I/Os makes it suitable for a broad range of system designs:

• Industrial Automation and Motor Control: The EP4CE30 handles multi-axis servo control loops, encoder interfaces, PWM generation, and real-time sensor fusion. The 66 multiplier blocks accelerate PID calculations and coordinate transformations without consuming general-purpose logic.
• Video and Image Processing: With 328 I/O pins and substantial logic and memory resources, the EP4CE30F23C8N supports VGA/HDMI display controllers, camera sensor interfaces (DVP parallel), real-time image filtering, and framebuffer management. The ALINX AX530 development board pairs this FPGA with DDR2 SDRAM and video connectors for rapid prototyping.
• Communications Protocol Bridging: The extensive I/O bank structure with eight independent V_CCIO domains enables flexible multi-voltage protocol translation — bridging between processors, ADCs, DACs, and communication interfaces such as Ethernet PHYs, SPI, I2C, UART, and custom serial engines.
• Embedded DSP and Baseband Processing: The 66 multiplier blocks support FIR/IIR filtering, FFT computation, digital down-conversion, and modulation/demodulation. Quartus Prime includes optimized DSP IP cores (FIR Compiler, FFT, NCO) that efficiently map to the Cyclone IV E multiplier architecture.

For power supply design, Altera recommends separate decoupling for V_CCINT (1.2 V core), V_CCIO (per-bank), and V_CCA (PLL analog supply at 2.5 V). Each power ball on the BGA should have a 0.1 µF ceramic capacitor placed within 2 mm of the via, supplemented by bulk capacitors of 10–47 µF per rail. The BGA land pattern requires at least 6 PCB layers for full pin escape routing. Browse Cyclone IV Series components for related power management and configuration ICs.

5. Equivalents, Cross-Reference, and Lifecycle

Intel announced in March 2024 that the Cyclone IV product line will remain in active production through at least 2040, guaranteeing long-term supply for designs using the EP4CE30F23C8N. Quartus Prime Lite and Standard editions continue to support Cyclone IV through version 23.1 and beyond, with the toolchain placed in maintenance mode (continued bug fixes, no new features).

For engineers evaluating migration paths or pin-compatible alternatives, the following cross-reference is useful:

• EP4CE30F23C7N — Same die and package, faster speed grade C7 (437.5 MHz). Drop-in replacement when higher clock performance is needed.
• EP4CE30F23C6N — Same die and package, fastest speed grade C6 (472.5 MHz). Use when timing closure at C8 is difficult.
• EP4CE40F23C8N — Next step up in the Cyclone IV E family with 39,600 LEs in the same 484-FBGA package. Pin-compatible upgrade path when logic utilization exceeds 80%.
• EP4CE22F17C8N — Smaller 256-FBGA package variant with 22,320 LEs and 153 I/Os. Consider for space-constrained designs with fewer I/O requirements.
• 10CL030YE144C8G (Cyclone 10 LP) — Intel's recommended forward migration for new designs. Similar logic density (30,000 LEs) in a different package with improved power efficiency and continued active development.

Second-source options for the EP4CE30 die do not exist, as Cyclone IV is proprietary to Intel. However, functionally equivalent devices from competing vendors include the Lattice ECP5-25F (24,000 LUTs, open-source toolchain) and Xilinx Spartan-7 XC7S50 (52,160 logic cells, Vivado toolchain). Neither is pin-compatible.

The ALINX AX530 development board, which features this exact FPGA, includes an on-board USB Blaster and ships with Verilog HDL demo projects and documentation.

Q: What is the maximum operating frequency of the EP4CE30F23C8N?

A: The EP4CE30F23C8N carries speed grade C8, the slowest of three commercial grades. Its global clock network performance reaches approximately 402 MHz, with core fabric speeds up to 420 MHz for simple register-to-register paths. The faster C6 and C7 grades of the same die achieve 472.5 MHz and 437.5 MHz respectively. Actual achievable frequency depends on design complexity, routing congestion, and timing constraints applied during Quartus compilation.

Q: What package type is the EP4CE30F23C8N and what are its PCB layout considerations?

A: The EP4CE30F23C8N uses a 484-pin FineLine BGA (FBGA) package with a 23 × 23 mm body and 1.0 mm ball pitch. PCB layout requires a minimum of 6 routing layers for full pin escape. Each power ball requires a 0.1 µF ceramic capacitor placed within 2 mm of the via, supplemented by 10–47 µF bulk capacitors per power rail. The BGA requires reflow soldering with a controlled thermal profile per JEDEC J-STD-020 guidelines.

Q: Can the EP4CE30F23C8N interface with DDR2 SDRAM?

A: Yes. The Cyclone IV E family supports DDR, DDR2, and SDR SDRAM external memory interfaces. The 484-FBGA package provides sufficient DQS-capable pins for up to a 32-bit DDR2 data bus. Quartus Prime includes the ALTMEMPHY megafunction to generate optimized memory controllers with DLL-based clock phase calibration. The ALINX AX530 development board demonstrates a working 2 Gbit DDR2 SDRAM interface running at full speed with this FPGA.

Q: What are the power consumption characteristics of the EP4CE30F23C8N?

A: Static power consumption at 85 °C junction temperature is typically 70–90 mW. Dynamic power depends on design-specific factors including clock frequency, toggle rate, logic utilization, and I/O switching activity. Intel provides the PowerPlay Early Power Estimator (EPE) spreadsheet for pre-design budgeting and the Quartus Prime Power Analyzer for post-compilation accuracy. The 1.2 V core supply and 60 nm process keep total power below 1.5 W for most typical designs. The 484-FBGA package offers good thermal dissipation through the ball array to the PCB ground plane, eliminating the need for a heatsink in most applications.
