EP3SL340F1517C4N Overview

The Intel (formerly Altera) EP3SL340F1517C4N is a high-density, low-power Stratix III L family Field Programmable Gate Array (FPGA) IC built on a 65 nm process, providing 337,500 logic elements, 18,822,144 bits of embedded memory, and 976 user I/Os in a 1517-ball FC-BGA package. The "L" variant of Stratix III delivers the lowest static power in the family while preserving the high-performance fabric architecture that established Stratix III as a benchmark in DSP and transceiver-based designs.

A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard IP such as transceivers, memory blocks, and DSP slices. Within the broader hierarchy, an FPGA belongs to programmable logic devices, sitting alongside CPLDs and structured ASICs. Stratix III FPGAs implement a logic-element fabric with adaptive logic modules (ALMs), on-chip M9K/M144K memory blocks, and dedicated DSP blocks, enabling parallel processing of wide data paths with deterministic latency.

Key features of the EP3SL340F1517C4N include 13,500 LABs, up to 450 MHz fabric performance, support for multiple I/O standards (LVDS, LVTTL, LVCMOS, HSTL, SSTL, PCIe), embedded transceivers at multi-gigabit data rates, and a 1.1 V core supply. The "C4" speed grade indicates a specific Fmax bin, while the trailing "N" denotes lead-free / Pb-free termination. The 1517-ball flip-chip BGA package provides high signal density for designs requiring hundreds of differential pairs and high fanout.

Typical applications include high-performance digital signal processing (radar, software-defined radio), ASIC prototyping, high-speed serial protocol bridging (PCI Express, Serial RapidIO, GIGABIT Ethernet), broadcast video processing, and high-end test and measurement instrumentation. The combination of 18.8 Mbits of embedded memory and 13,500 LABs makes this device suitable for designs that require both deep buffering and complex state machines.

When designing with this part, ensure your PCB BGA layout supports 1.0 mm ball pitch fanout, and that thermal management accounts for the larger die. Quartus II design software (legacy) or Intel Quartus Prime is required for synthesis, place-and-route, and bitstream generation. Static power is a key metric in Stratix III L - use the PowerPlay Early Power Estimator to validate thermal envelopes before PCB commitment.

Key Differentiators

  • Highest-density Stratix III L variant in 1517-FCBGA (vs EP3SE260F1517C4N)
  • Lowest static power in the Stratix III generation (vs EP3SL340H780I4N (H variant))
  • C4 speed grade provides ~10-15% higher Fmax than C3 (vs EP3SL340F1517C3N)

Design Notes

Estimated: at full fabric utilization (337,500 LEs switching at 450 MHz), the 1517-ball FC-BGA may dissipate 8-12 W. With FC-BGA packages, attach a copper heat-spreader or forced-air cooling. Run the PowerPlay Early Power Estimator in Quartus Prime to validate junction temperature; target Tj below 100C for reliable long-life operation. The "L" (low static power) variant of Stratix III reduces leakage by ~30-50% vs the standard variant, easing thermal envelopes.

The 1517-ball FC-BGA uses a 1.0 mm ball pitch, requiring a high-layer-count PCB (12+ layers) with microvia and via-in-pad technology. Use a high-Tg (Tg > 170C) low-Df/Dk material such as Megastura 6 or equivalent to meet multi-Gbps SERDES signal-integrity targets. Per the Altera Stratix III handbook, follow the pin-out guidelines in the package chapter for power-pin and GND via placement to ensure solid reference planes under the BGA field.

Stratix III requires multiple regulated supplies (VCC, VCCAUX, VCCPD, VCCIO per bank, VTT for DDR). Use a dedicated power controller such as the LTM4628 or EN5339QI plus discrete LDO post-regulation. Per Quartus power-estimator output, allow at least 20% headroom on each rail; inrush at startup can exceed steady-state by 2-3x. Decoupling: place 0402/0201 ceramics directly under each BGA ball pair with via-in-pad for shortest loop inductance.

Do not omit the CFGBLK configuration clock source (typically 50 MHz TCXO) on the dedicated CFG pin pair - the device will not enumerate without it. JTAG chain order matters when multiple FPGAs share TDI/TMS - assign unique 5-bit JTAG IDCODEs in Quartus assignments. For 65 nm Stratix III devices, ensure SEU (single-event upset) scrubbing logic is implemented if used in aerospace/defense where soft-error rates exceed 1 FIT/Mbit.

Multi-gigabit transceivers require controlled-impedance routing (100 ohm differential) with matched lengths within 5 mil for lanes above 5 Gbps. Reference plane continuity must be preserved across layer transitions; avoid ground-plane splits under transceiver channels. Use IBIC-AMI models from Intel for channel simulation in tools such as Keysight ADS or Cadence Sigrity before PCB commitment.
