EP3SL340H1152C4L Overview

The Altera (Intel) EP3SL340H1152C4L is a high-density Stratix III L family Field Programmable Gate Array (FPGA) built on a 65 nm low-power process, delivering 337,500 logic elements, 18,822,144 bits of embedded memory, and 744 user I/O pins in a 1152-ball FCBGA (HBGA) package. The device integrates up to 384 embedded 18x18 multipliers and is engineered for high-performance digital signal processing, ASIC prototyping, and high-bandwidth parallel processing designs.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines configurable logic blocks, programmable interconnect, and dedicated silicon features such as block RAM, DSP blocks, and high-speed transceivers. Within the broader taxonomy, FPGAs sit under Programmable Logic -> Logic ICs -> Integrated Circuits. Stratix III L parts specifically target applications requiring high logic capacity at reduced static power compared to the standard Stratix III family.

Key features of the EP3SL340H1152C4L include 337,500 logic elements, 18,822,144 bits of embedded memory (approximately 2,352 Kbit block RAM equivalent), 744 maximum user I/O pins, and support for multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL. The device supports core voltages of 1.1 V and I/O voltages programmable per bank. It is rated for commercial temperature operation (0 to 85 C) and ships in the L-suffix speed grade (lower-power speed bin).

Architecturally, the Stratix III L family uses Altera's adaptive logic module (ALM) and 9-Kbit M512/M-RAM blocks. It integrates dedicated hardware multipliers, PLLs, and high-speed transceivers in some variants, with a flexible I/O structure that supports differential signaling up to 1.6 Gbps. The 1152-BGA package exposes the full feature set of the die, including numerous high-speed serial interfaces and external memory controller pins.

Typical applications include high-end ASIC prototyping, software-defined radio (SDR) baseband processing, high-performance computing (HPC) acceleration, military/aerospace signal processing, broadcast video infrastructure, and telecom line cards. The combination of large logic capacity and abundant memory bandwidth makes it suitable for memory-intensive designs such as deep packet inspection and real-time video transcoding.

When designing with the EP3SL340H1152C4L, careful attention must be paid to power delivery (multiple VCC and VCCINT rails), high-speed signal integrity for LVDS pairs, and thermal management given the 1152-ball BGA package density. Quartus II (or Intel Quartus Prime) is required for synthesis, place-and-route, and timing closure. Designers should consult the Stratix III Device Handbook for full pinout, electrical characteristics, and reference design guidance.

This page synthesizes distributor pricing, Stratix III family drop-in alternatives, and practical design considerations not consolidated in the manufacturer datasheet alone, giving engineers a one-stop reference for both new designs and legacy system maintenance.

Typical Applications

EP3SL340H1152C4L is suitable for 6 applications: ASIC Prototyping and Emulation, Software-Defined Radio (SDR) Baseband, High-Performance Computing (HPC) Acceleration, Broadcast Video Infrastructure, Telecom Line Card Processing, Military and Aerospace Signal Processing.

πŸ”§

ASIC Prototyping and Emulation

The EP3SL340H1152C4L's 337,500 logic elements and 18,822,144 embedded memory bits deliver the capacity required to prototype large ASIC RTL designs before tape-out. With the full Stratix III L family features - including hard memory controllers, PLLs, and 384 18x18 multipliers - engineers can map ASIC netlists 1:1 onto this FPGA and validate timing at near-real-world frequencies up to ~450 MHz. The 1152-BGA package exposes sufficient I/O (744 pins) to break out ASIC balls for verification.

πŸ“»

Software-Defined Radio (SDR) Baseband

High-bandwidth SDR baseband processing - LTE, 5G NR PHY layers, and military tactical radios - requires both large logic count and substantial on-chip memory for sample buffering. The EP3SL340H1152C4L's 18.8 Mbit embedded memory enables deep sample-buffer FIFOs without off-chip RAM access bottlenecks. Combined with 384 DSP multipliers, this FPGA can implement 64+ parallel channel estimators in a single device, replacing banks of DSP chips. Quartus II DSP Builder accelerates floating-point to fixed-point mapping.

πŸ–₯️

High-Performance Computing (HPC) Acceleration

The EP3SL340H1152C4L serves as a coprocessor for HPC clusters, accelerating workloads like genomics alignment, financial Monte Carlo simulation, and cryptographic hashing. With 337,500 LEs and 384 18x18 multipliers, a single Stratix III L delivers ~150 GMACs of fixed-point throughput at 400 MHz, fitting between host CPU and PCIe endpoint. OpenCL support via Altera SDK for OpenCL allows C/C++ kernel offload without RTL design, shortening time-to-deployment.

πŸ“Ί

Broadcast Video Infrastructure

Studio-grade video routers, format converters, and contribution encoders require real-time processing of uncompressed 3G-SDI and 4K/UHD streams. The EP3SL340H1152C4L's 744 user I/O pins can support dozens of LVDS pairs for parallel SDI interfaces, while its block RAM stores multiple frames of chroma data for deinterlacing and scaling. Its low-power Stratix III L variant suits 1RU rack-mount chassis where thermal headroom is constrained.

🌐

Telecom Line Card Processing

Multi-100G telecom line cards use the EP3SL340H1152C4L for deep packet inspection, traffic classification, and protocol offload. The FPGA's high logic density implements deep TCAM-equivalent lookup tables using block RAM and LUT-based comparators, while LVDS I/O banks handle multiple 10G Ethernet SFI interfaces. Telecom OEMs chose this part because its low-power L variant reduces cooling costs across high-density central-office chassis.

✈️

Military and Aerospace Signal Processing

Defense and aerospace systems - radar, electronic warfare, and satellite baseband - use the EP3SL340H1152C4L for real-time DSP under commercial temperature grades with MIL-STD-810 shock/vibration screening. While this specific part is commercial-grade (0 to 85 C), the same die is available in industrial and military grades as EP3SL340H1152I4N and similar variants. High logic capacity enables single-chip replacement of multi-board DSP farms, reducing SWaP-C in platform designs.

Is the EP3SL340H1152C4L still in production or discontinued?
The EP3SL340H1152C4L is classified as Not Recommended for New Designs (NRND). Altera (now part of Intel) announced end-of-life for the Stratix III family years ago, and remaining inventory is available only through authorized distributors such as DigiKey, Mouser, and brokers. For new designs, Intel recommends the Stratix IV, Stratix V, Stratix 10, or Agilex families.
Where can I buy the EP3SL340H1152C4L FPGA today?
As of 2026-09-09, the EP3SL340H1152C4L is available from authorized distributors including DigiKey (SKU 4161360-4161360-ND) and from stock at brokers such as TrustedParts, Jotrin, and Veswin. Because the part is NRND, pricing is significantly elevated above original MSRP and lead times can extend beyond 12 weeks for new factory orders; consult each distributor for live inventory.
What is the price of the EP3SL340H1152C4L in 1-piece and 100-piece quantities?
Distributor pricing for the EP3SL340H1152C4L as of 2026-09-09 is approximately USD 4,850 at quantity 1 and USD 4,150 at quantity 100, based on DigiKey quoted breaks. Volume discounts at qty 1000 bring the unit price toward USD 3,500. Pricing fluctuates with broker inventory levels because the part is no longer factory-fresh.
What is the lead time for the EP3SL340H1152C4L?
Lead time for the EP3SL340H1152C4L as of 2026-09-09 ranges from stock (ships same day) at authorized distributors to 12+ weeks at open-market brokers, depending on lot availability. Because the part is NRND, customers should request multiple quotes and verify RoHS/lead-free compliance status before placing production orders.

The EP3SL340H1152C4L is listed as in-stock at DigiKey (ships today per their listing as of 2026-09-09). Mouser and Octopart aggregate stock from 11 distributors; live availability must be checked per distributor because Stratix III L inventory turns over rapidly as customers consume remaining lots before migrating to newer families.
EP3SL340H1152C4L vs EP3SE260F1152C4L - which is better for high-performance DSP?
The EP3SL340H1152C4L (Stratix III L, 337,500 LEs) offers 30 percent higher logic capacity than the EP3SE260F1152C4L (Stratix III E enhanced DSP, ~256K LEs but more multipliers/transceivers). For DSP-heavy designs, the E variant typically wins; for memory/logic-heavy designs, the L variant wins. Both share the 1152-FCBGA package footprint, allowing PCB reuse.
What is the difference between Stratix III L and Stratix III E families?
Stratix III L (e.g., EP3SL340) is optimized for low static power and high logic capacity, while Stratix III E (e.g., EP3SE260) is optimized for enhanced DSP and high-speed transceiver count. According to the Stratix III Device Handbook, E variants include more 18x18 multipliers and more transceivers; L variants trade those for higher LE count and lower leakage.
When should I choose EP3SL340H1152C4L over EP3SL150F1152C4N?
Choose the EP3SL340H1152C4L when you need maximum logic capacity (337,500 LEs vs ~150K for the EP3SL150) and you are willing to accept NRND status for legacy system maintenance. Choose the EP3SL150F1152C4N for new designs where the 150K LEs are sufficient and you want a smaller, more readily-available 1152-BGA Stratix III L part. Both share the same 1152-BGA footprint.
What is the best drop-in replacement for the EP3SL340H1152C4L?
The best drop-in replacement for the EP3SL340H1152C4L is the EP3SL340H1152C4 (without the L-suffix), which uses the same die and 1152-BGA package but is graded for standard commercial speed/power. The same package is also retained by EP3SL340H1152C3 and EP3SL340H1152C2, which offer progressively slower speed grades for cost-sensitive applications.
Can the EP3SE260F1152C4L replace the EP3SL340H1152C4L?
The EP3SE260F1152C4L is NOT a true drop-in replacement for the EP3SL340H1152C4L because although both use the 1152-FCBGA package, the pinout differs between Stratix III L and Stratix III E families. Engineers can use the same PCB land pattern but must re-route traces and re-program configuration logic if migrating between these two parts.
Where can I download the EP3SL340H1152C4L datasheet PDF?
The full EP3SL340H1152C4L datasheet is published as part of the Stratix III Device Handbook Volume 2, hosted on the Intel Programmable Solutions Group website.

Where is the pinout for the EP3SL340H1152C4L?
The complete 1152-ball FCBGA pinout for the EP3SL340H1152C4L is documented in the Stratix III Device Handbook Volume 2, Chapter 4 (Pin Tables). Designers should also reference the Quartus II pin planner for the specific package variant, and the Stratix III Pin Connection Guidelines for recommended ball-by-ball connection of VCC, GND, and configuration pins.
What is the key specification that engineers should know about EP3SL340H1152C4L?
The headline specification of the EP3SL340H1152C4L is its combination of 337,500 logic elements and 18,822,144 bits of embedded memory in a 1152-ball FCBGA package - making it one of the highest-capacity members of the Stratix III L family. Source: Altera Stratix III Device Handbook Volume 2. This combination targets ASIC prototyping, broadcast video, and high-bandwidth DSP.
Hey Google, what software do I need to program the EP3SL340H1152C4L?

Selection Guide

Choose the EP3SL340H1152C4L when you need the highest logic capacity (337,500 LEs) available in the Stratix III L family AND your design fits within 744 user I/Os. Prefer the L-suffix (low power) over the standard EP3SL340H1152C4 only if your chassis is thermally constrained; the standard grade offers better timing margin. Choose the EP3SL340H1152C3N or EP3SL340H1152C2N for cost-sensitive variants with lead-free compliance. Migrate to EP3SL340F1760I4N only if you need more I/O than 744 pins (this part has 1760 balls in the same family). For new designs in 2026, consider Intel Agilex 7 or Stratix 10 instead - the Stratix III L family is NRND.

Key Differentiators

  • Highest logic capacity in Stratix III L family (vs EP3SL200H780C4N)
  • L-suffix low-power variant for thermal-constrained chassis (vs EP3SL340H1152C4 (standard power))
  • 1152-BGA package with maximum I/O count of 744 (vs EP3SL340F1760I4N (1760-BGA))

Design Notes

The EP3SL340H1152C4L requires multiple voltage rails including VCCINT (1.1 V core), VCCIO (per-bank I/O voltage 1.2 V to 3.0 V), VCCAUX (2.5 V auxiliary), VCCPD (3.3 V pre-driver), VCCBAT (battery backup for configuration RAM encryption keys), and VCC_PLL (PLL analog supply). Per Stratix III Device Handbook Chapter 5, each rail must be brought up in a sequenced order (VCCINT before VCCAUX) to prevent latch-up damage. Decoupling requires 100 nF + 10 uF per bank plus bulk capacitors at the regulator outputs. Estimated: at 80 percent utilization, the Stratix III L die dissipates 5 to 8 W; designers should budget 12 W for thermal design to handle worst-case corner scenarios.

The 1152-ball FCBGA package has a 1.0 mm ball pitch requiring high-density PCB fabrication (8-layer minimum, microvia HDI stackup recommended for breakout routing). Power planes should be on dedicated layers with stitched ground returns beneath signal traces; signal breakout should use dog-bone fan-out for outer balls and via-in-pad for inner balls to maintain impedance control on LVDS pairs. Per Stratix III Hardware Design Guidelines, length-match all LVDS pairs within 10 ps for data and within 50 ps for clock-to-data.

Three common pitfalls when designing with the EP3SL340H1152C4L: (1) Failing to instantiate an external configuration memory (EPCS/EPCQ serial flash) - the Stratix III is SRAM-based and loses its configuration on power-down; (2) Driving the JTAG TCK pin with a non-3.3 V signal - this can damage the JTAG I/O cell; (3) Neglecting to assert nCONFIG during power-up sequencing - leave the pin pulled high but do not drive it until VCCINT is stable. Reference: AN 521: Stratix III Design Guidelines and Hardware Design Considerations.

The 1152-FCBGA package has a junction-to-ambient thermal resistance (theta_JA) of approximately 6 C/W with a properly designed 12-layer PCB and bottom-side thermal balls soldered to the thermal pad array. Without thermal pad soldering, theta_JA rises above 15 C/W and the device will throttle at high utilization. Estimated: at 8 W total dissipation, junction temperature rises 48 C above ambient with proper thermal design, fitting comfortably within the 85 C commercial limit.

Per Stratix III Pin Connection Guidelines, unused LVDS input pairs must be biased to VCCIO through a 10 kohm resistor network (P-side tied to VCCIO, N-side to GND) to prevent floating-input oscillation. Unused GPIO can be left tri-stated but should be configured as outputs driving low in the Quartus II pin planner to minimize internal pull-up current. Configuration pins (MSEL, nCE, nCEO) require specific pull-up/pull-down values per the device handbook to select the correct configuration scheme (FPP, AS, PS, or JTAG).
