EP2C35F672I8N 개요
A Field-Programmable Gate Array is a reconfigurable digital integrated circuit whose logic fabric, interconnect, and I/O can be electrically programmed after PCB assembly. Within the broader silicon taxonomy, FPGAs sit alongside ASICs, microcontrollers, and DSPs as programmable logic devices, but uniquely offer hardware-level parallelism, sub-cycle latency, and on-the-fly reconfiguration. Cyclone II represents Altera's second-generation low-cost FPGA family, optimized for high-volume cost-sensitive designs where ASIC NRE is unjustified.
Key features of the EP2C35F672I8N include 33,216 logic elements, 35 embedded 18x18 multipliers (132 9x9 multipliers) for DSP-style arithmetic, 483,840 bits of embedded RAM arranged across M4K blocks, 475 user I/O pins, and four phase-locked loops for clock synthesis and management. The 672-BGA package provides 35x35 ball array with 1.0 mm pitch, enabling dense PCB escape routing while still allowing conventional reflow assembly.
Architecturally, the Cyclone II device uses a four-input look-up table (LUT4) logic element, true dual-port M4K memory blocks, and dedicated multiplier blocks adjacent to the logic array. The 672-BGA package supports up to 8 high-speed LVDS channels and 16 global clock networks. Configuration is loaded through passive serial (PS), fast passive parallel (FPP), or JTAG modes using the Altera Quartus design toolchain.
Typical applications span industrial motor control, video processing pipelines, software-defined radio front-ends, automotive driver-assistance prototyping, communications protocol bridging, and cost-optimized ASIC prototyping where moderate logic density and abundant I/O are required. The 475 user I/O count and 35 hardware multipliers make it well suited to parallel data acquisition and image preprocessing.
When designing with the EP2C35F672I8N, ensure the PCB layout honors the BGA escape pattern with microvia or via-in-pad technology to reach inner-layer routing. Confirm that JTAG, configuration, and decoupling pins are accessible to the programmer, and that the PLL power supply filtering follows the Cyclone II handbook reference schematic.

설계 노트
The 672-BGA package uses 1.0 mm ball pitch, which is at the practical limit of conventional PCB fabrication. Designers should plan for microvia or via-in-pad technology to achieve reliable inner-layer escape routing. A 4-layer or 6-layer stack-up with buried capacitance is recommended for the inner power/ground plane pair. Maintain a continuous ground plane beneath the BGA to control return-path impedance and reduce SSO noise. Estimated: signal escape assumes 0.1 mm trace/space on outer microvia layer.
Cyclone II devices require at least three separate supply rails: VCCINT (1.2 V core), VCCIO (1.5 V to 3.3 V I/O bank, bank-dependent), and VCC_PLL (1.2 V analog PLL supply). Decoupling must follow the handbook reference schematic with 0.1 uF and 10 uF combinations near every power pin. Use a ferrite bead to isolate VCC_PLL from VCCINT noise. Estimated: bulk decoupling at 1 uF per PLLs and 0.1 uF per VCCIO pin.
Match JTAG chain length and impedance to the 4-wire TMS/TCK/TDO/TDI specification. Provide a robust 4.7 kohm pull-up on TCK and TDI, and route configuration signals away from switching I/O to avoid configuration corruption during power-up. Expose JTAG and AS/PS configuration mode pins to accessible test points or header pins for in-field reprogramming. Cyclone II recommends 25 MHz MSEL settings for active serial configuration with EPCS flash devices.
