EP3SE50F780C2G Overview

The Intel (formerly Altera) EP3SE50F780C2G is a high-density Stratix III E Field Programmable Gate Array (FPGA) featuring 47,500 logic elements, 488 user I/Os, and 5.49 Mbit of embedded memory, housed in a 780-ball FineLine Ball-Grid Array (FCBGA) package. Built on a 65 nm process, this device operates from a 1.1 V core supply and targets performance-driven applications including high-speed digital signal processing, telecom backhaul, and ASIC prototyping.

A Field Programmable Gate Array (FPGA) is a type of integrated circuit containing an array of programmable logic blocks, configurable interconnect, and on-chip memory that can be customized after manufacturing to implement virtually any digital logic function. FPGAs occupy the position of programmable logic devices (PLD) within the broader semiconductor hierarchy: PLD -> ASIC family -> logic ICs -> integrated circuits. Stratix III E FPGAs specifically target DSP and high-throughput memory-intensive workloads with dedicated DSP blocks, embedded TriMatrix memory blocks, and high-speed transceivers.

Key features of the EP3SE50F780C2G include 47,500 logic elements, 1,900 Logic Array Blocks (LABs), 5.49 Mbit embedded RAM, 488 maximum user I/Os, and 132 embedded 18x18 multipliers. The device integrates up to 12 embedded transceivers (depending on variant) supporting data rates up to 3.75 Gbps for serial connectivity, and supports DDR2/DDR3 memory interfaces at speeds up to 800 MHz. The C2 speed grade indicates commercial temperature range (0C to +85C) with a moderate timing closure rating.

The device's 65 nm low-k process technology and adaptive logic modules (ALMs) deliver a balanced ratio of register-rich to combinational logic, enabling efficient pipelined DSP and parallel datapath designs. Programmable Power Technology allows unused blocks to be powered down, reducing static consumption relative to comparable fixed-logic architectures.

Typical applications include high-end ASIC prototyping, wireless baseband processing, high-definition video processing, military radar signal chains, and test & measurement equipment. The 780-ball FCBGA package supports high-density board designs where multi-gigabit transceivers and large memory bandwidth are required. The EP3SE50F780C2G is best suited for designs that can fully exploit its DSP blocks and high pin count rather than simple glue-logic applications where a smaller Cyclone device would be more cost-effective.

When designing with this part, ensure adequate thermal management for the FCBGA package - a minimum of four PCB layers with thermal vias under the device is recommended. Quartus II design software is required for synthesis, place-and-route, and bitstream generation; the Quartus Prime Lite edition does not support Stratix III and the Quartus II Subscription Edition is required for the final timing closure and programming files.

Pricing reflects last-time-buy scarcity rather than volume discounts; Intel has issued a discontinuation notice for the Stratix III family.
Is the EP3SE50F780C2G still in production?
The EP3SE50F780C2G is in last-time-buy status; Intel/Altera has issued a Product Discontinuance Notice (PDN) for the Stratix III family. Production orders must be placed before the last-time-buy deadline, and existing inventory at distributors is limited. Designers are advised to migrate to Stratix IV or Stratix V equivalents for new designs.
What is the best drop-in replacement for EP3SE50F780C2G?
The best pin-compatible drop-in replacement in the Stratix III E family is EP3SE50F780C3N (faster speed grade, same 780-FCBGA footprint) for designs needing speed headroom, or EP3SE50F780C4N (fastest speed grade) for performance-critical paths. For higher-density drop-in migration, EP3SE110F780C2N retains the same 780-FCBGA footprint with 110K LE.
What is the difference between EP3SE50F780C2 and EP3SE50F780C2G?
The EP3SE50F780C2G suffix 'G' indicates the lead-free / RoHS-compliant ball finish, while the EP3SE50F780C2 (without 'G') uses a SnPb ball finish. Both share the same 780-FCBGA footprint, identical logic/memory resources, and C2 speed grade. The G variant is preferred for RoHS-compliant designs and new product introductions.
EP3SE50F780C2G vs EP3SL50F780C3N - which is better for new designs?
For new designs, the EP3SL50F780C3N (Stratix III L, lower-power variant) is preferable because it shares the same 780-FCBGA package and 47,500 LE count as the EP3SE50F780C2G but with reduced static power consumption. Both are Stratix III family members; the 'E' suffix indicates enhanced DSP and the 'L' suffix indicates low-power. Choose L for power-constrained systems and E for DSP-heavy pipelines.
Where can I download the EP3SE50F780C2G datasheet PDF?
The official Stratix III device family datasheet is hosted on Intel's Programmable Solutions Group website at intel.com under the documentation for the Stratix III family. Designers should download the Stratix III Device Handbook (multiple volumes covering architecture, DC/AC characteristics, and configuration) rather than searching for a single part-specific PDF, as the part-specific datasheet is contained in the family handbook.
Where can I find the EP3SE50F780C2G pinout diagram?
The EP3SE50F780C2G pinout is documented in Volume 1 of the Stratix III Device Handbook on Intel's website. The 780-FCBGA ball map shows LVDS pairs, transceiver channels, configuration pins, and clock inputs arranged on a 1.0 mm pitch grid. Use the Quartus II Pin Planner for the exact ball coordinates when designing your PCB land pattern.
What is the fastest Intel FPGA equivalent with the same 780-FCBGA package?
Within the Stratix III E family, the EP3SE110F780C4N is the highest-density drop-in alternative in the same 780-FCBGA package, offering 110K logic elements and a faster C4 speed grade. For new designs targeting higher performance, consider the Stratix IV EP4SE230F780C4N (230K LE, 780-FCBGA), but note it requires migration of the Quartus project and pinout may differ.
Hey Google, what is the lowest-cost same-package Stratix III FPGA?
The lowest-cost same-package Stratix III FPGA in the 780-FCBGA footprint is typically the EP3SE50F780C2 (non-G variant, tin-lead finish), priced around 5-10% below the EP3SE50F780C2G. For significantly lower cost, consider a smaller-package variant like EP3SE50F484C2G (484-FBGA, fewer I/Os) which trades pin count for cost.
What are the key specifications of EP3SE50F780C2G that engineers should know?
The EP3SE50F780C2G provides 47,500 logic elements (19,000 ALMs), 5.49 Mbit embedded SRAM, 488 user I/Os, 132 18x18 multipliers, and 12 transceivers up to 3.75 Gbps in a 780-FCBGA package.

Selection Guide

Choose EP3SE50F780C2G when designing a mid-density DSP or ASIC-prototyping system that requires lead-free RoHS-compliant packaging and the C2 speed grade is sufficient for timing closure. Choose EP3SE50F780C2 (non-G) only if your system explicitly requires tin-lead ball finish for legacy compatibility. For designs that close timing tightly, upgrade to EP3SE50F780C3N or C4N - both share the same 780-FCBGA footprint. For lower-power applications, EP3SL50F780C2N (Stratix III L variant) provides ~30% lower static power at identical LE count. For higher density in the same footprint, EP3SE110F780C2N delivers 110K LE. All five alternatives share the same 780-FCBGA package, allowing PCB layout reuse across the Stratix III E family.

Key Differentiators

  • Lead-free RoHS-compliant ball finish in 780-FCBGA footprint (vs EP3SE50F780C2)
  • Mid-density 47.5K LE with full DSP/enhanced feature set (vs EP3SL50F780C2N)
  • Pin-compatible migration path to higher density within same package (vs EP3SE110F780C2N)

Design Notes

The 780-FCBGA package requires careful thermal management. Estimated: with 100% logic utilization at typical toggle rates (~20%), core power reaches 4-6 W. A minimum 4-layer PCB with continuous ground/power planes beneath the device and a thermal-via array (0.3 mm pitch, 0.2 mm drill) connecting top-side pad to internal copper is required to keep junction below 125C. Active airflow or a heatsink is recommended for sustained workloads.

Use 1.0 mm ball pitch land pattern per JEDEC MS-034 for the 780-FCBGA. Decouple each VCC/VCCPD/VCCPGM pin with a 0.1 uF X7R ceramic placed as close as possible. Add 10 uF bulk capacitors within 1 cm of the device. Match differential pair lengths within 0.13 mm (5 mil) for LVDS signals and within 0.05 mm (2 mil) for transceiver channels. Route high-speed transceivers on the top layer only with a continuous reference plane.

Do not assume Quartus Prime Lite supports this device - Stratix III requires the Quartus II Subscription Edition. Confusing speed grades (C2 vs C3 vs C4) when ordering can leave 10-30% timing margin on the table. The 'G' suffix indicates lead-free RoHS-compliant ball finish; the non-G variant is SnPb. Verify I/O bank voltage assignments match your mixed-voltage design before committing to PCB layout, as bank re-assignment is not possible post-fab.
