EP2C35F484I6N 개요
An FPGA (field-programmable gate array) is a reconfigurable semiconductor device whose logic function is defined by a customer-supplied bitstream rather than hard-wired during fabrication. The Cyclone II family sits within the broader programmable logic taxonomy: FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor. Unlike microcontrollers which execute sequential firmware, FPGAs implement parallel hardware logic that can be updated in the field, making them ideal for prototyping, low-volume production, and applications where hardware parallelism outperforms software. The EP2C35 specifically targets the mid-density segment with 33K logic elements, balancing cost per logic element against capability.
Key features of the EP2C35F484I6N include 2,100 Logic Array Blocks (LABs) organized in 33,216 logic elements (LEs), 483,840 bits of embedded RAM (M4K blocks), 4 phase-locked loops (PLLs) for clock management, and 315 embedded 18x18 multipliers in the Cyclone II family (the EP2C35 provides 35 embedded multipliers per Cyclone II datasheet). The device supports multiple I/O standards including LVDS, SSTL, HSTL, PCI, and PCI-X through configurable user I/O banks. Its 1.2 V core voltage with 1.2 V/2.5 V/3.3 V I/O supplies enables mixed-voltage system design.
The Cyclone II architecture uses a 4-input look-up table (LUT) based logic element with a dedicated carry chain, distributed M4K memory blocks, and embedded multiplier blocks. This heterogeneous fabric allows efficient implementation of arithmetic DSP pipelines, FIFO buffers, and state-machine control logic without external components. The PLLs provide clock multiplication, division, phase shifting, and duty-cycle correction for interfacing with external memory and high-speed peripherals.
Typical applications for the EP2C35F484I6N include industrial motor control, video processing and image filtering, telecommunications line cards, software-defined radio DSP front-ends, and automotive driver-assistance prototypes. Designers choose the EP2C35 when they need a balance of logic density, DSP performance, and BGA packaging for high-pin-count systems. The 484-ball FBGA package supports the maximum user I/O count of the device, enabling wide parallel buses and multiple high-speed serial interfaces simultaneously.
When designing with this device, engineers should follow Intel/Altera board layout guidelines for BGA fanout, power-plane decoupling, and PLL analog supply isolation. The Quartus II design suite (now Intel Quartus Prime) provides synthesis, place-and-route, and timing analysis for the Cyclone II family. Because the EP2C35F484I6N is a mature part originally launched circa 2005, engineers should verify current lifecycle status before new design starts.
This page synthesizes distributor pricing, drop-in pin-compatible alternatives from the Cyclone II family, and practical board-level design notes not found in the manufacturer datasheet alone. It is intended for engineers evaluating mid-density FPGAs for cost-sensitive parallel-processing designs.

설계 노트
The 484-ball FBGA package uses 1.0 mm ball pitch and requires microvia or via-in-pad PCB technology for reliable fanout. Designers should follow Intel/Altera Cyclone II Board Design Guidelines for layer stackup, including dedicated power and ground planes adjacent to the BGA footprint. Decoupling capacitors (0.1 uF, 0.01 uF, and bulk 10-100 uF) must be placed within 100 mils of the device's power balls. Estimated: assuming a 6-layer stackup with 50 ohm controlled-impedance routing, total board area for the EP2C35F484 footprint is approximately 25x25 mm.
The EP2C35F484I6N requires three supply rails: VCCINT (1.2 V core), VCCIO (1.2 V/2.5 V/3.3 V I/O, per bank), and VCCA_PLL (2.5 V analog supply for the 4 PLLs). The PLL analog supply must be isolated from digital noise with an LC filter (typical 10 uH inductor + 10 uF capacitor) to meet jitter specifications. Power sequencing requires VCCINT to rise before or simultaneously with VCCIO; failing to sequence can cause latch-up or long-term reliability degradation. Estimated: at 50% toggle rate with 322 I/O active, ICCINT is approximately 500 mA and ICCIO ranges 200-800 mA per bank.
A common design pitfall is assuming the EP2C35F484I6N is pin-compatible with newer Cyclone IV or Cyclone V devices despite sharing the same FBGA-484 package - the pinouts differ between device families and board rework is required for migration. Another pitfall is using unsupported configuration modes; the Cyclone II family supports only AS (Altera/Intel serial), PS (parallel), JTAG, and PPA configuration - newer boot modes like Avalon-ST are not available. Designers should also verify bitstream compatibility when migrating between speed grades (I6, C7, C8) of the same die, as timing constraints differ.
High-speed LVDS and DDR memory interfaces on the EP2C35F484I6N require matched-length routing within 50 mils and controlled differential impedance (100 ohm differential for LVDS, 50 ohm single-ended for SSTL). Use the Cyclone II Device Handbook's I/O timing specifications to calculate setup/hold margins at your target clock frequency. The Quartus II TimeQuest timing analyzer must be run with realistic board delays to verify margins before tape-out.
