EP2A40F672C8N 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. APEX II devices sit in the programmable logic hierarchy as follows: PLD -> CPLD/FPGA -> high-density FPGA with embedded memory and I/O. The APEX II family specifically targets high-performance datapath, communications, and ASIC-replacement designs where dense logic and high I/O count are required.
Key features of the EP2A40F672C8N include 1.5 M system gates, 38,400 logic elements, 4 embedded PLLs for clock synthesis, dedicated high-speed LVDS channels supporting 1 Gbps data rates, a 1.5 V nominal core supply (1.425 V to 1.575 V range), and 492 user I/Os. The propagation delay is rated at 1.55 ns for internal logic, and the device supports in-system programming via the JTAG boundary-scan interface per IEEE 1149.1.
Architecturally, the EP2A40F672C8N uses a MultiCore structure of Look-up Tables (LUTs), embedded array blocks (EABs) for memory and DSP functions, and FastTrack interconnect routing. The 0.15 µm copper process enables high transistor density while maintaining low dynamic power. Built-in PLLs simplify clock tree synthesis, and LVDS support is critical for high-speed parallel interfaces such as SPI-4.2, Rapid I/O, and POS-PHY.
Typical applications include telecommunications switching and routing equipment, ASIC prototyping and emulation, high-speed datapath processing, digital signal processing front-ends, and high-density glue-logic replacement. With 492 user I/Os, the device is well-suited for systems that require wide memory buses (DDR SDRAM controllers) or multiple parallel channel interfaces.
When designing with this device, ensure the 1.5 V core supply is generated by a low-noise regulator such as the TPS7A4701 to meet the VCCINT tolerance. The 672-ball BGA package requires a multilayer PCB (typically 6 or more layers) with controlled-impedance routing for LVDS signals and matched-length traces for clocks.

主な用途
EP2A40F672C8N の用途: 7 件s: Telecommunications Switching and Routing, ASIC Prototyping and Emulation, High-Speed Datapath Processing, Industrial Automation and Control, Digital Signal Processing Front-Ends, High-Density Glue Logic Replacement, Test and Measurement Instrumentation.
Telecommunications Switching and Routing
The EP2A40F672C8N's 1.5M gates, 492 user I/Os, and 1 Gbps LVDS capability make it well-suited for telecom switching fabrics and routing line cards. The 672-ball FineLine BGA exposes enough I/O to drive parallel POS-PHY Level 4 (SPI-4.2) interfaces alongside network processors. With 4 embedded PLLs, multiple clock domains for TDM, ATM, and packet pipelines can be synthesized independently. The APEX II embedded array blocks (EABs) implement CAMs and lookup tables for routing table acceleration. This FPGA was commonly paired with network processors such as the Intel IXP1200 in legacy router designs.
おすすめ
ASIC Prototyping and Emulation
With 38,400 logic elements and 1.5M system gates, the EP2A40F672C8N emulates mid-range ASICs in pre-silicon validation. The 492 user I/Os support wide external buses and DDR SDRAM interfaces, allowing real-world firmware bring-up before tapeout. The 1 Gbps LVDS channels mimic high-speed serial ASIC links. Engineers commonly partition ASIC RTL across multiple EP2A40 devices using JTAG chaining. Multi-FPGA partitioning tools such as Synopsys Certify and Mentor Graphics Precision Hi-Rel target this device family.
おすすめ
High-Speed Datapath Processing
The EP2A40F672C8N's 376 MHz maximum internal frequency and 1.55 ns propagation delay enable high-throughput datapath pipelines in DSP, video, and image processing. Embedded array blocks (EABs) implement parallel multipliers and FIR filters efficiently. With 4 PLLs and 492 I/Os, the device connects to external DDR memory and high-speed ADCs/DACs without bottlenecks. APEX II EABs also support dual-port RAM for line buffers in video processing. The 1.5V low core voltage keeps dynamic power manageable at 376 MHz operation.
おすすめ
Industrial Automation and Control
Industrial control systems leverage the EP2A40F672C8N's 492 I/Os for parallel sensor aggregation, motor control PWM, and fieldbus bridging. The 0 °C to 85 °C commercial temperature range suits factory-floor enclosures. APEX II logic density accommodates multi-axis motion controllers and complex state machines. The LVDS channels support high-noise-immunity industrial links such as LVDS-based fieldbus extensions. The device's JTAG support (IEEE 1149.1) enables in-system programming during equipment commissioning and field updates.
おすすめ
Digital Signal Processing Front-Ends
The EP2A40F672C8N's embedded array blocks (EABs) implement fast Fourier transforms (FFTs), digital down-converters (DDCs), and FIR filters directly in hardware. Combined with 4 PLLs for sample-clock synthesis and 1 Gbps LVDS for ADC/DAC interfacing, the device suits radar, sonar, and software-defined radio front-ends. The 38,400-cell capacity supports multiple parallel processing channels. APEX II was widely adopted in 3G/4G base-station digital pre-distortion (DPD) feedback paths where parallel processing is essential.
おすすめ
High-Density Glue Logic Replacement
Designers replace multiple discrete CPLDs and ASICs with the EP2A40F672C8N to consolidate board real-estate and simplify routing. The 1.5M gates provide ample capacity for bus arbitration, interrupt controllers, and protocol bridges. The 672-ball BGA consolidates many TTL-level functions into a single device. APEX II's in-system programmability via JTAG allows post-assembly bug fixes. The 1.5V core and 3.3V I/O compatibility retains legacy 5V-tolerant interfaces via level shifters such as the SN74LVC4245A.
おすすめ
Test and Measurement Instrumentation
Test equipment designers leverage the EP2A40F672C8N for arbitrary waveform generation, protocol analysis, and logic analyzer capture. The 492 I/Os enable wide parallel stimulus/response channels, while EABs implement deep pattern memories. The 4 PLLs synthesize multiple precise sample clocks for multi-rate acquisition. LVDS channels support high-speed serial protocol decoding such as PCI Express and Serial RapidIO. The 1.5V core is readily generated by the TPS7A4701 low-noise LDO for jitter-sensitive timing paths.

設計ノート
Generate the 1.5 V VCCINT rail with a low-noise LDO such as the TPS7A4701 (4.17 uVrms noise) placed within 1 inch of the BGA balls. Use a 6-layer PCB with two dedicated power planes: layer 2 for VCCINT, layer 5 for GND. Decouple each VCCINT ball with a 0.1 µF X7R ceramic plus a 10 µF bulk tantalum; add 1 µF on each VCC_PLL ball to minimize PLL jitter. Decoupling capacitor placement is critical: traces must be shorter than 50 mils to the ball.
Estimated: at 376 MHz toggle rate with 70% logic utilization, the EP2A40F672C8N can dissipate 3-5 W. The 672-ball FC-FBGA has a theta_JA of approximately 12-15 C/W with a properly designed thermal via array under the package. Use a 5x5 thermal via array (0.3 mm drill, 1.0 mm pitch) stitched to the inner GND plane. Without thermal vias, junction temperature can exceed 125 °C at full toggle rate. For continuous high-utilization designs, attach a heatsink via thermal interface material (TIM).
The 27x27 mm 672-ball FC-FBGA with 1.0 mm pitch requires a 6 or 8-layer PCB. Microvia (HDI) technology with 0.1 mm laser-drilled vias is recommended for breakout routing. Use 4-mil traces and 4-mil spaces in inner layers; outer layers should use 5-mil traces. Matched-length routing (±50 mil) is required for LVDS pairs and global clocks. Stitch all GND vias around the BGA perimeter to suppress edge radiation.
LVDS channels operating at 1 Gbps require 100 Ω differential impedance with controlled skew under 20 ps. Use AC-coupled termination at the receiver for inter-board LVDS links. For internal LVDS within the same PCB, use DC-coupled 100 Ω differential termination at the EP2A40F672C8N LVDS pins. Series-damping resistors (10-22 Ω) at the FPGA driver pins reduce reflection and overshoot. Keep LVDS pairs at least 3x trace-width spacing from other signals.
Do not exceed VCCINT beyond 1.575 V or below 1.425 V - permanent damage will occur. JTAG configuration requires TCK slower than 33 MHz for reliable programming. Do not leave unused I/O pins floating; configure them as outputs driving low or as inputs with weak pull-ups to avoid additional leakage. When migrating from speed grade 8 to 7 or 6, re-validate static timing analysis (STA) with the Quartus Prime speed-grade-specific timing models.
