EP3SL70F484C2N Overview

The Intel EP3SL70F484C2N is a 65nm Stratix III L-series Field Programmable Gate Array (FPGA) with 67,500 logic elements (LEs), 2,699,264 bits of embedded memory, and 296 user I/Os, housed in a 484-pin flip-chip BGA (FC-FBGA) package. It operates on a 1.1V core supply at up to 600 MHz fabric speed and is qualified for the commercial 0C to +85C temperature grade (suffix C2).

An FPGA (Field Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (LBs/LEs) interconnected by a programmable routing fabric, surrounded by programmable I/O cells and hardened peripherals such as block RAM, DSP blocks, PLLs, and high-speed transceivers. FPGAs sit in the broader taxonomy: programmable logic -> logic IC -> integrated circuit -> semiconductor. The Stratix III family uses a low-power 65nm process with programmable power-rail gating to reduce static consumption versus prior 90nm Stratix II.

Key features of the EP3SL70F484C2N include 2,700 LABs (Logic Array Blocks), embedded multipliers, and a high-speed I/O architecture supporting common single-ended and differential signaling standards used in telecom, broadcast, and high-performance DSP. The device is part of the Stratix III L (logic-rich) variant, which maximizes logic density and on-chip memory rather than transceiver count, making it suitable for ASIC prototyping and complex state-machine designs.

The 484-pin FC-FBGA package provides a 1.0 mm ball pitch and a flip-chip land-side thermal path, which yields a junction-to-board thermal resistance that enables high-utilization designs without an external heatsink in most commercial-temperature applications. The C2 speed grade and N suffix denote a lead-free, commercial-temperature, non-RoHS-exempt (Pb-free reflow compatible) order code.

Typical applications include ASIC and ASSP prototyping, high-speed DSP pipelines, test and measurement equipment, video processing, motor control, and telecom baseband logic. The device is also widely used in legacy industrial, aerospace, and defense programs where the long-life-cycle Stratix III silicon continues to ship. Designers can use the Quartus II design software (Web Edition or Subscription Edition) for synthesis, place-and-route, and timing closure.

When designing with the EP3SL70F484C2N, plan power sequencing for the 1.1V core and 2.5V/3.3V I/O rails and provide a sufficient via array under the package thermal pad. Pin-compatible same-footprint Stratix III family members enable capacity scaling on the same PCB.

Typical Applications

EP3SL70F484C2N is suitable for 7 applications: ASIC and ASSP Prototyping, High-Speed DSP Pipelines, Test and Measurement Equipment, Telecom Baseband and Protocol Processing, Industrial Motor Control, Video Processing and Broadcast, Legacy Aerospace and Defense Sustainment.

🔧

ASIC and ASSP Prototyping

The EP3SL70F484C2N is widely used as an ASIC prototyping vehicle because its 67,500 LEs, 2,699,264 embedded memory bits, and Quartus II tool flow map closely to ASIC gate-equivalent capacity. The 484-ball FC-FBGA package exposes 296 user I/Os - more than enough to break out typical ASIC prototype pin counts - while the C2 commercial speed grade supports up to 600 MHz fabric operation, sufficient for emulating most ASIC clock domains at full speed.

📡

High-Speed DSP Pipelines

Stratix III L-series devices embed dedicated 18x18 multipliers and DSP blocks alongside the 67,500 LEs, making the EP3SL70F484C2N suitable for high-speed DSP pipelines such as radar signal processing, software-defined radio baseband, and video codec acceleration. The fabric runs up to 600 MHz, and the abundant block RAM (2.7 Mb total) enables multi-stage FIR/FFT implementations without external memory round-trips.

🔬

Test and Measurement Equipment

The EP3SL70F484C2N serves as the timing controller and DSP core in test-and-measurement instruments such as oscilloscopes, logic analyzers, and protocol testers. Its 296 user I/Os can drive multiple high-speed ADC/DAC interfaces (LVDS, DDR), and the 1.1V core with programmable power gating reduces thermal load in fanless chassis designs. The C2 commercial grade is sufficient for lab bench equipment operating at room temperature.

🌐

Telecom Baseband and Protocol Processing

Telecom equipment uses the EP3SL70F484C2N for baseband processing, MAC-layer protocol handling, and framer/mapper functions where the 67.5K LEs map cleanly to multi-channel 10G/40G datapaths. The 484-ball FC-FBGA package supports the SERDES reference clocks and multiple LVDS lanes typical of telecom line cards. Designers typically pair the FPGA with external PHY and optics modules on the same board.

🏭

Industrial Motor Control

In industrial servo drives and motor controllers, the EP3SL70F484C2N implements field-oriented control (FOC), encoder interfaces (EnDat, BISS, SSI), and safety logic in a single device. Its 296 user I/Os handle multi-axis encoder feedback, while the 65nm process provides predictable latency for deterministic control loops. The industrial variant EP3SL70F484I4N is preferred for factory-floor temperature ranges.

📺

Video Processing and Broadcast

Broadcast video routers, format converters, and multi-viewer systems rely on the EP3SL70F484C2N's combination of high fabric speed (600 MHz), abundant block RAM for line buffers, and 296 user I/Os for SDI/HDMI/DVI signal routing. The Stratix III fabric supports the multi-standard I/O required for SDI (SMPTE 259M/292M/424M) at the LVDS levels typical of serializer/deserializer (SerDes) companion chips.

✈️

Legacy Aerospace and Defense Sustainment

Long-life-cycle aerospace and defense programs continue to specify the EP3SL70F484C2N because the Stratix III silicon is well-characterized, has mature Quartus II support, and remains on authorized distributor allocation lists. Military and aerospace board designs use the C2 commercial temperature grade for ground systems and the I4 industrial grade for airborne platforms.

What is the logic element count of the EP3SL70F484C2N?
The EP3SL70F484C2N contains 67,500 logic elements (LEs) organized into 2,700 LABs. According to the Intel Stratix III device handbook, this L-series part is optimized for logic-rich applications such as ASIC prototyping and complex state-machine designs, trading transceiver count for higher logic and memory density versus the GX variants.
What package does the EP3SL70F484C2N use?
The EP3SL70F484C2N is housed in a 484-ball flip-chip fine-pitch BGA (FC-FBGA) package with 1.0 mm ball pitch. The flip-chip construction provides a low-inductance die-to-package interface and a thermal path directly through the land-side balls, which is critical for the 1.1V core supply at multi-amp load currents typical of Stratix III designs.
Is the EP3SL70F484C2N still in production?
The EP3SL70F484C2N is classified Not Recommended for New Designs (NRND) by Intel. Existing orders through authorized distributors continue to be supported, but the Stratix III family has been superseded by Stratix IV, V, and 10 series devices. Engineers building new designs should evaluate Stratix IV/V/10 or Cyclone V/10 for new projects while continuing to use this part for legacy sustainment.
What is the difference between C2 and I4 speed grades on this device?
The C2 suffix denotes the second-fastest commercial-temperature speed grade (0C to +85C) for the EP3SL70F484C2N, while I4 denotes the slowest industrial-temperature speed grade (-40C to +100C). C2 parts run faster in commercial environments but are not guaranteed to meet timing across the industrial range. According to the Stratix III datasheet, C2 is typically chosen for lab and commercial equipment; I4/I5 is preferred for harsh-environment or outdoor systems.
Where can I buy the EP3SL70F484C2N online?
The EP3SL70F484C2N is stocked at DigiKey, Mouser, and several authorized Intel/Altera distributors including Avnet and Future Electronics. Octopart aggregates 7 distributor listings for this MPN as of 2026-09-10, with lead times varying from immediate (DigiKey) to 8-12 weeks for larger quantities through franchised channels.
What is the price of the EP3SL70F484C2N at qty 1?
The unit price at qty 1 is approximately USD 215.00 as of 2026-09-10 based on Octopart aggregated distributor listings. Pricing scales down to roughly USD 149.50 at qty 1000, reflecting typical FPGA volume discounting. Pricing fluctuates with foundry capacity and lifecycle phase; NRND parts often see rising prices as distributor stock is consumed.
What is the lead time for EP3SL70F484C2N orders?
Lead time for the EP3SL70F484C2N varies by distributor. As of 2026-09-10, DigiKey shows immediate shipping for small quantities, while larger production orders through Intel-direct or franchised distributors carry 8-12 week lead times due to the NRND status. Engineers should confirm current lead times at order placement because NRND parts can shift to obsolete status with limited notice.
EP3SL70F484C2N vs EP3SL110F1152C2N - which is better for high-density DSP?
Both devices share the Stratix III L-family architecture but differ in capacity: EP3SL70 has 67,500 LEs and EP3SL110 has approximately 107,500 LEs. For high-density DSP pipelines, the EP3SL110F1152C2N provides 60% more logic and more DSP blocks, but uses the larger 1152-ball FBGA package. The EP3SL70F484C2N remains the better choice when board area is constrained or when the design is below ~85% utilization on the L-series silicon.
When should I choose EP3SL70F484C2N over a Cyclone V FPGA?
Choose the EP3SL70F484C2N when you need Stratix III-class fabric performance (600 MHz, 67.5K LEs, abundant block RAM) for ASIC prototyping, high-speed DSP, or legacy Stratix III reference designs. Choose a Cyclone V E/GX/GT part instead for new low-cost, low-power designs where Cyclone V's 28nm process node delivers better power efficiency at lower cost.
What is the best drop-in replacement for EP3SL70F484C2N?
The best drop-in pin-compatible replacement within the Stratix III family is the EP3SL70F484C2G (RoHS-compliant, lead-free finish) or the EP3SL70F484C2 (legacy finish code). Both share the same 484-ball FC-FBGA footprint, die, and 67,500-LE fabric as the EP3SL70F484C2N. For new designs, consider EP3SL70F484I4N (industrial temperature) or migrate to a Stratix IV/V equivalent in the same FBGA footprint.
Can a Xilinx Spartan-6 replace the EP3SL70F484C2N?
A Xilinx Spartan-6 is functionally similar but is NOT a drop-in replacement for the EP3SL70F484C2N. The Stratix III and Spartan-6 use different packages, different I/O standards at the silicon level, and require different PCB layouts and Quartus vs ISE/Vivado toolchains. A pin-compatible cross-brand replacement for this Stratix III in a 484-ball FC-FBGA is not generally available from Xilinx because Xilinx uses different BGA ball maps even at the same pin count.
Where to download EP3SL70F484C2N datasheet PDF?
The official Stratix III device handbook is available on the Intel FPGA support page at intel.com/content/www/us/en/products/programmable/fpga/stratix-iii/support.html, which links to the device family datasheet covering all EP3SL part numbers including the EP3SL70F484C2N. Octopart and DigiKey product pages also host datasheet PDF downloads linked from their respective EP3SL70F484C2N product pages.

The package has 22 user I/O banks and dedicated clock, configuration, and JTAG pins. PCB layout files (.bxl/.pcb) are also available from Altera/Intel's PCB library for Altium Designer and Cadence Allegro users.
What software do I need to program the EP3SL70F484C2N?
The EP3SL70F484C2N is programmed using Intel Quartus II design software - either the free Quartus II Web Edition (for Cyclone and limited Stratix III device support) or the Quartus II Subscription Edition (full Stratix III support including SignalTap II logic analyzer, TimeQuest timing analyzer, and SOPC Builder). Intel recommends Quartus II version 13.1 or later for final timing closure on the Stratix III family.
Is the EP3SL70F484C2N RoHS compliant?
The EP3SL70F484C2N is lead-free and Pb-free reflow compatible per its 'N' suffix, and is RoHS compliant for the 484-ball FC-FBGA package. The Stratix III family was among the first Intel/Altera high-end FPGA families to convert to lead-free ball finishes, enabling reflow profiles up to 245C peak per IPC/JEDEC J-STD-020 MSL-3 preconditioning.

Selection Guide

Choose the EP3SL70F484C2N when you need a mature, well-supported 65nm Stratix III FPGA in the 484-ball FC-FBGA package at C2 commercial speed grade - typical for ASIC prototyping, high-speed DSP pipelines, and lab bench test-and-measurement equipment. If the design exceeds 85% LE utilization on the EP3SL70, migrate up to the EP3SL110 (1152-ball FBGA) on a new PCB. If the design fits comfortably below 60% utilization, downsize to the EP3SL50F484C2N for cost savings on the same footprint. For industrial temperature operation, choose the EP3SL70F484I4N variant (industrial -40C to +100C, slower I4 grade). For new designs, evaluate Stratix IV/V or Cyclone V/10 instead of designing in an NRND Stratix III part.

Key Differentiators

  • Highest logic density in the 484-ball FC-FBGA Stratix III family (vs EP3SL50F484C2N)
  • Commercial C2 speed grade - faster than industrial I4 (vs EP3SL70F484I4N)
  • RoHS-compliant lead-free finish (N suffix) (vs EP3SL70F484C2)
  • Logic-rich L-series with 2.7 Mb embedded memory (vs EP3SE80F780C2N)

Design Notes

The Stratix III core runs at 1.1V and the I/O rails at 2.5V/3.3V with auxiliary voltages for PLL and transceiver supplies. Power sequencing must ramp VCCINT (1.1V) before VCCIO to avoid I/O driving into unpowered silicon. The 65nm process with programmable power gating can reduce static consumption by 40-60% versus Stratix II; use the Quartus II PowerPlay analyzer to estimate per-rail current before PCB layout. Decoupling: place 0.1uF X7R MLCCs within 5 mm of every VCCINT pin and 10uF bulk capacitors on each supply plane.

The 484-ball FC-FBGA package uses a flip-chip land-side thermal path. The PCB land pattern must include a thermal via array (0.3 mm drill, 0.5 mm pitch, 1 oz copper fill) directly under the die shadow to maintain theta_JB within the datasheet spec. Without thermal vias, junction temperature can exceed the 85C C-grade limit at high utilization. Estimated: a typical 67K-LE design at 60% utilization and 500 MHz draws ~3-5W; with proper thermal vias the 484-FBGA easily handles this without an external heatsink.

PCB layout for the 484-ball FC-FBGA at 1.0 mm ball pitch requires 4 mil (0.1 mm) trace-and-space rules with laser-drilled microvias. Use 8-layer stack-up with two solid ground planes adjacent to the BGA fan-out area for return-path integrity on high-speed LVDS pairs. Match lengths within +/- 50 mil for DDR/Source-Synchronous interfaces; the Quartus II pin planner will report required tsu/th margins once place-and-route is complete.

Do not assume all 484-ball FBGA Stratix III parts are interchangeable: EP3SL (logic-rich), EP3SE (DSP-rich), and EP3SGX (with transceivers) share the same package but have different ball maps for power, GND, and special-function pins - swapping an L for an E without re-routing will fail. Always verify the ball map from the device handbook before PCB respin. Also note: the C2 speed grade is commercial-only; for industrial temperature, choose I4 or I5.
