EP3SL340F1517C2 Overview

The Altera (Intel) EP3SL340F1517C2 is a high-density, low-power Stratix III L family Field Programmable Gate Array (FPGA) with 337,500 logic elements, 18,822,144 bits of embedded memory, 600 MHz core performance, and 976 user I/Os, housed in a 1517-ball Flip-Chip BGA (FCBGA) package. Built on a 65 nm process node with a 1.1 V core supply, this device is targeted at high-throughput DSP, telecom, and high-performance digital designs where logic density and memory bandwidth dominate.

An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory blocks, DSP blocks, and programmable I/Os interconnected by a routed fabric. FPGAs occupy the programmable logic layer of the broader semiconductor hierarchy: FPGA -> programmable logic -> digital IC -> integrated circuit. Unlike fixed-function ASICs, FPGAs are post-fabrication reprogrammable, enabling rapid prototyping, hardware acceleration, and design iteration.

Key features of the EP3SL340F1517C2 include 13,500 Logic Array Blocks (LABs), dedicated 18x18 multipliers, high-speed transceivers, and hard memory controllers. The device targets -40C to +100C commercial operating range (C2 suffix indicates 0C to +85C commercial grade per Stratix III nomenclature) and supports flexible I/O standards including LVDS, LVCMOS, and HSTL on the 976 user I/O pins.

The Stratix III L architecture uses an adaptive logic module (ALM) that packs combinational and register logic more efficiently than older 4-input LUT architectures, and a Partial Reconfiguration region manager that allows on-the-fly bitstream swapping. Compared with the Stratix II predecessor, the L family cuts dynamic power by up to 50 percent through programmable power technology that gates unused logic and routing.

Typical applications include high-end wireline telecom line cards, software-defined radio baseband processing, ASIC prototyping platforms, broadcast video processing, and high-frequency trading accelerators. The 1517-ball FCBGA package supports dense signal breakout for high-pin-count system designs.

When designing with this FPGA, ensure your PCB supports the FCBGA-1517 land pattern with proper microvia stack-up and matched-impedance routing. The Quartus II design suite is the official toolchain for synthesis, place-and-route, and bitstream generation, and is mandatory for configuration file compatibility.

Selection Guide

Choose the EP3SL340F1517C2 when you need the highest-density Stratix III L FPGA in the FCBGA-1517 footprint at commercial temperature and a moderate 600 MHz Fmax is sufficient. Choose EP3SL340F1517C2N if you require an explicitly Pb-free variant for compliance. Choose EP3SL340F1517C3 or C4 if your timing closure requires a higher Fmax; all share the same package. Choose EP4SE340F1517C2 only when migrating to Stratix IV E and need higher DSP throughput; the 40 nm node increases power but supports faster clocks. For designs needing industrial temperature (-40C to +100C), pick the -I3 or -I4 speed grade instead of the -C2 family.

Key Differentiators

  • Highest-density Stratix III L variant in the FCBGA-1517 package (vs EP3SL200F1517I4N)
  • Low-power 65 nm architecture compared with later-generation FPGAs (vs EP4SE340F1517C2)
  • Pin-compatible upgrade path from C2 to C4 speed grade (vs EP3SL340F1517C4)

Design Notes

The FCBGA-1517 package requires a high-density PCB stack-up with microvia (laser-drilled) technology for inner-layer fan-out. Standard 4-layer FR-4 is insufficient; design for at least 8 layers with 1 oz copper and matched 50-ohm impedance on high-speed transceiver pairs. Decoupling capacitor selection is critical: use 0402-size 0.1 uF and 10 uF ceramics distributed beneath the device following the reference capacitor map in the Stratix III pin-out file. Estimated: power delivery network impedance target is below 5 mOhm at 100 MHz to handle simultaneous switching noise from 976 I/Os.

At full logic utilization (337,500 LE switching) and 600 MHz operation, junction power can approach 25-30 W. The FCBGA-1517 package has a theta_JC of approximately 0.15 C/W and requires a forced-air heatsink plus thermal interface material. Estimated: with a 4 m/s airflow and a properly attached heatsink, junction-to-ambient thermal resistance is approximately 1.2 C/W, yielding a temperature rise of 36 C above ambient at 30 W. For passive cooling, consider the -I3 or -I4 speed grade variants at slightly lower clock frequencies.

Do not mix Quartus II versions across team members when targeting this device; bitstream compatibility breaks between major Quartus versions. Verify the configuration mode (Passive Serial, Fast Passive Parallel, or Active Serial) matches the design's configuration PROM or download cable. Most importantly, follow the Stratix III power-sequencing order in chapter 4 of the handbook - mis-sequencing Vccint before Vccpd can cause long-term reliability degradation that may not show up in bench testing but fails in the field within months.

High-speed transceiver channels (if used) require length-matched differential pairs with a skew budget under 5 ps. Use 100-ohm differential impedance and follow the DTR (Documenting the Routing) constraints exported by Quartus II during board layout. Cross-talk mitigation: maintain at least 3W spacing between adjacent TX/RX pairs and avoid routing signals over splits in reference planes. The FCBGA-1517 package's BGA escape routing typically requires blind/buried vias - plan your fabrication house's capabilities early.
