EP3SL340H1152C2 Overview

The Intel EP3SL340H1152C2 is a high-density Stratix III L family Field Programmable Gate Array (FPGA) delivering 337,500 logic cells, 18,822,144 bits of embedded memory, and 744 user I/O in a 1152-ball Fine-Pitch Ball Grid Array (FBGA) package. Manufactured on a 65 nm CMOS process with a 1.1 V core supply, this device targets high-performance digital signal processing, telecommunications, and high-throughput data-path applications where logic density and memory bandwidth are paramount. It provides up to 13,500 LABs and supports multiple high-speed serial transceiver protocols for backplane and chip-to-chip connectivity.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device that combines the flexibility of software-configurable logic with the performance of application-specific integrated circuits. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs), which also include CPLDs and PALs, and they are widely used for prototyping ASICs, accelerating compute-intensive workloads, and implementing custom parallel processing pipelines. The Stratix III family specifically targets designs that need the highest logic density and DSP performance available at low power budgets, with features like high-speed transceivers and rich on-chip memory.

Key features of the EP3SL340H1152C2 include 744 user I/O pins supporting a wide range of single-ended and differential I/O standards, up to 18.8 Mbits of embedded RAM organized in M9K and MLAB blocks for flexible buffering and FIFO implementation, dedicated DSP blocks for high-throughput arithmetic operations, and clock management tiles that enable multiple clock domains with low jitter. The 1152-BGA FCBGA package provides a compact footprint relative to its I/O count while offering controlled-impedance signal paths ideal for high-speed memory and transceiver interfaces.

Typical applications include high-throughput digital signal processing in software-defined radio (SDR), radar, and beamforming systems; telecommunication infrastructure such as baseband processing and high-speed packet inspection; ASIC prototyping and design verification for networking ASICs and processor emulation; high-performance computing accelerators in data centers and test equipment; video and image processing pipelines requiring wide memory bandwidth; and industrial control and automation systems with real-time deterministic latency requirements.

When designing with this FPGA, engineers should pay close attention to the PCB layout for the 1152-ball BGA, ensuring proper decoupling, power-plane integrity, and via-in-pad or microvia construction to maintain signal integrity at high toggle frequencies. Plan a robust power distribution network using multiple voltage rails (core, PLL, I/O banks, transceiver) and follow the manufacturer's recommended power-on sequencing. Thermal management requires sufficient airflow or heatsinking because the device's high logic density produces non-trivial power dissipation under sustained workload.

This page synthesizes distributor pricing, parametric context, and design guidance that is not available from the manufacturer datasheet alone, providing a single reference for engineers evaluating the EP3SL340H1152C2 for new designs or replacements.

Selection Guide

Choose the EP3SL340H1152C2 when your design requires the highest logic density (337K cells) and a high I/O count (744 user I/O) within the Stratix III L family, and when you need the C2 commercial speed grade for cost-effective, non-industrial environments. For industrial or extended-temperature deployments, prefer the I3/I4 speed-grade variants (e.g., EP3SL340H1152I3N). For lower-density designs where 200K cells are sufficient, the EP3SL200 variants offer a cost reduction at similar I/O counts. The H variant is required when high-speed serial transceivers are needed; otherwise the F variant (e.g., EP3SL340F1152C2N) provides the same logic density without transceiver circuitry.

Key Differentiators

  • High-density Stratix III L with 337.5K cells and 744 user I/O (vs EP3SL200F1152C2)
  • C2 commercial speed grade at 1152-BGA (vs EP3SL340H1152I4N)
  • H variant includes high-speed transceivers (vs EP3SL340F1152C2N)

Design Notes

The 1152-ball FBGA package requires via-in-pad or microvia PCB construction to route signals out from the dense ball array. Use a multi-layer PCB with dedicated ground and power planes for the 1.1 V core supply and I/O bank voltages, and follow the Stratix III PCB design guidelines for BGA breakout, decoupling capacitor placement, and stack-up. Signal traces must maintain 50 ohm single-ended or 100 ohm differential impedance for high-speed memory and transceiver interfaces.

Estimated: At typical Stratix III L power dissipation of 8-12 W under sustained workload, a 1152-BGA device without heatsinking may exceed its 85C junction limit. Designers should provide thermal vias under the BGA thermal pad, copper pours on inner layers, and optionally a heatsink for high-utilization designs. Industrial-grade (I3/I4) speed grades should be considered for systems with elevated ambient temperatures.

The EP3SL340H1152C2 requires multiple voltage rails (core 1.1 V, PLL analog, I/O banks at 1.2-3.0 V, transceiver if present). Use the Stratix III power-sequencing guidelines: core must come up before I/O. Decoupling capacitors should be placed as close as possible to each power pin with a mix of bulk, mid-frequency, and high-frequency values per the device handbook. Power-on reset behavior must be validated with the chosen configuration scheme.

Common pitfalls when designing with the EP3SL340H1152C2 include insufficient PCB layer count for BGA breakout, ignoring the recommended power-up sequencing (causing I/O latch-up), insufficient decoupling (causing core voltage droop during configuration), and over-constraining timing without specifying the correct speed grade. Always validate pin assignments against the Stratix III pinout file and verify that the chosen speed grade meets your Fmax requirements.
