EP2C35F484C7 Visão geral
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and dedicated silicon resources such as block RAM (BRAM) and DSP blocks. FPGAs sit within the broader category of programmable logic devices (PLDs), bridging the gap between fixed-function ASICs and software-programmable microcontrollers. The Cyclone II architecture organizes logic into Logic Array Blocks (LABs) of 16 Logic Elements (LEs) each, with embedded memory columns and multiplier blocks distributed across the fabric to minimize routing delay and maximize deterministic performance.
Key features of the EP2C35F484C7 include 322 maximum user I/O pins, four phase-locked loops (PLLs) for clock management, support for external memory interfaces such as DDR, DDR2, and QDRII SRAM, and a flexible configuration scheme supporting JTAG, Passive Serial (PS), and Active Serial (AS) modes. The device supports LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards, enabling direct interfacing with modern processors, memories, and high-speed peripherals.
Typical applications for the EP2C35F484C7 span cost-sensitive digital signal processing, motor control, industrial automation, video processing, and protocol bridging. The combination of 33K logic elements, 35 hardware multipliers, and 484-ball FBGA packaging makes the device particularly attractive for medium-density DSP pipelines, motor and motion controllers, and telecommunications infrastructure where deterministic hardware-level processing outperforms general-purpose processors.
When designing with this Cyclone II device, engineers should leverage the Altera/Intel Quartus II design suite for synthesis, place-and-route, and timing closure. The FBGA-484 package requires careful PCB layout with controlled-impedance traces, matched-length nets for DDR interfaces, and multiple decoupling capacitors placed close to each power pin to maintain signal integrity at the device's high toggle rates.

Notas de projeto
The EP2C35F484C7 requires multiple power rails: VCCINT (1.2 V core), VCCIO (1.5 V / 1.8 V / 2.5 V / 3.3 V per bank), VCC_PLL (1.2 V analog PLL supply), and VCCA (2.5 V PLL analog). According to the Cyclone II Device Handbook, place a 0.1 uF decoupling capacitor within 5 mm of every VCCINT/VCCIO pin and a 1 uF bulk capacitor per power region. PLL analog supplies should be filtered with a ferrite bead or pi-filter to prevent core switching noise from coupling into PLL loops. Estimated: at 33K LE utilization, expect 1.5-3 W core dissipation depending on toggle rate.
The 484-ball FBGA package uses 1.0 mm ball pitch and requires either an 8-layer PCB with microvia stack-ups or a 6-layer board with HDI microvias to escape the inner rows. Per Cyclone II layout guidelines, maintain a continuous GND plane on layer 2 directly under the BGA, and route differential pairs (LVDS, DDR) with 100 ohm differential impedance. Matched-length tuning is required for DDR/DDR2 interfaces; use the Quartus II board-level timing report to set length tolerances.
Configure the EP2C35F484C7 via JTAG for prototyping or via Active Serial (AS) mode using an EPCS4/EPCS16/EPCS64 serial flash for production. According to Cyclone II handbook, MSEL[3:0] pins must be tied to select the configuration scheme; pull-ups on nCE and pull-down on nCONFIG enable correct power-on reset. CONF_DONE goes high when configuration completes - monitor it for system-level reset release.
LVDS inputs on the EP2C35F484C7 require a 100 ohm differential termination resistor across each LVDS pair as close to the FPGA pins as practical. According to Cyclone II I/O specifications, set VCCIO to 2.5 V when using LVDS-25 I/O standard. SSTL-2 and HSTL Class I/II memory interfaces require external VTT termination resistors at the memory-end bus midpoint, not at the FPGA. Use IBIS models from Intel for SI simulation.
Do not leave unused I/O pins floating - configure them as outputs driving ground or as inputs with internal weak pull-ups enabled. Floating I/O banks cause excessive current draw and may trigger configuration failures. According to Cyclone II hardware warnings, unused clock inputs must be tied to ground through a 1 kohm resistor to prevent oscillation. Always run Quartus II's 'Enable Open Drain' and 'Enable Bus Hold' options selectively, not globally.
