The device targets data-centric, memory-rich and DSP-intensive applications where its 896 18x18 multipliers, 4 memory-rich LABs and modular I/O banks with dynamic on-chip termination deliver best-in-class signal integrity. A Field Programmable Gate Array (FPGA) is a reprogrammable semiconductor device whose logic fabric, interconnect and I/O can be configured by the end user to implement custom digital circuits, soft processors, DSP pipelines and high-speed serial interfaces. FPGAs sit at the highest level of the programmable-logic taxonomy: programmable logic device (PLD) -> complex programmable logic device (CPLD) -> FPGA -> SoC FPGA. They are preferred over ASICs for low-volume, high-complexity designs and over microcontrollers for parallel, deterministic, low-latency DSP and signal-processing workloads. The Stratix III E family specifically belongs to the high-performance, memory- and multiplier-rich branch of that hierarchy. Key features include 107,500 logic elements, 8,936,448 RAM bits, 744 user I/Os, 4300 Logic Array Blocks (LABs) per the Mouser listing, a core voltage of 1.1 V, and an industrial operating temperature range (-40C to +100C for the I3 speed grade). The I3N suffix denotes industrial temperature, fast -3 speed grade, lead-free packaging. The device is built on a TSMC 65 nm process and supports up to 12.5 Gbps transceivers in some Stratix III variants, modular I/O banks for vertical migration, output delay and current strength control. Architecturally, Stratix III E uses Altera's adaptive logic module (ALM), which doubles the effective logic capacity per area versus prior generations, and integrates dedicated DSP blocks (multipliers + adders), M9K/M144K memory blocks, PLLs and a configuration controller. Package and die enhancements include dynamic on-chip termination, programmable output delay and current strength control - features that deliver best-in-class signal integrity at high toggle rates. Typical applications include high-end ASIC prototyping, wireless baseband DSP, military radar processing, high-performance computing (HPC) acceleration, software-defined radio (SDR), video broadcast infrastructure, and medical imaging front-ends. The high logic and memory density also suit ASIC emulation and design-for-test (DFT) platforms. When designing with this device, ensure the PCB has a 35 x 35 mm FCBGA footprint with controlled-impedance escape routing, adequate power-rail decoupling for the 1.1 V core and 2.5 V/3.3 V auxiliary supplies, and a JTAG header for Quartus II programming. Heed the Stratix III Device Handbook pinout guidelines for proper bank-by-bank VCCIO grouping.

The Intel (Altera) EP3SE110F1152I4 is a high-density Stratix III E family Field-Programmable Gate Array (FPGA) integrating 107,500 logic elements (LEs), 744 DSP blocks, and 8,936,448 bits of embedded memory (approximately 1.1 MByte) into a 1152-ball FineLine BGA (FCBGA) package. It operates across an industrial temperature range of -40°C to +100°C, supports up to 744 user I/Os, and is built on a 40nm process node that delivers high logic density with low static power. A Field-Programmable Gate Array (FPGA) is a semiconductor device built from a matrix of configurable logic blocks (CLBs), dedicated DSP slices, embedded memory blocks, and programmable I/O cells, all interconnected by a routed fabric. Within the broader integrated-circuit taxonomy, an FPGA belongs to programmable logic devices (PLDs), itself a subset of digital ICs. Stratix III E devices specifically target high-performance digital signal processing, high-throughput serial connectivity, and embedded processor subsystems where deterministic latency and parallel arithmetic matter more than the absolute logic capacity of a CPU. Key features include 4300 Logic Array Blocks (LABs) - Mouser lists this as the LABs figure - transceivers supporting up to 600 MHz fabric performance, embedded multiplier blocks for high-speed DSP, and dedicated memory interfaces including DDR3/DDR2/QDRII+ support. The device includes 24 phase-locked loops (PLLs) and supports multiple I/O standards including LVDS, HSTL, SSTL, and PCI Express. Configuration is supported through JTAG, passive serial, fast passive parallel, and Altera-specific modes such as Active Serial (AS) using an EPCS configuration device. Technically, the Stratix III E family improves the ratio of logic performance per watt over the prior Stratix II generation by combining a lower-power programmable logic fabric with on-chip DSP blocks and TriMatrix embedded memory that can be configured as RAM, ROM, shift registers, or FIFO buffers. The integrated transceivers support protocols such as PCI Express Gen1/Gen2, Gigabit Ethernet, Serial RapidIO, and XAUI at multi-gigabit rates. Typical applications include high-end communications infrastructure (10G/40G line cards, base-station DSP), high-performance test and measurement instrumentation, ASIC prototyping, high-throughput video processing, and embedded compute acceleration. The 1152-ball FCBGA package supports dense board designs where multi-channel I/O and memory interfaces must be routed out without compromising signal integrity. When designing with this device, plan for substantial power-delivery and thermal management: a 107.5K-LE design typically requires a multi-layer PCB with at least 6 layers, multiple decoupling capacitors per power rail, and thermal vias beneath the FCBGA. Configuration storage should use an EPCS flash device paired with JTAG for in-system reprogrammability. Pin compatibility within the Stratix III E family allows migration between density variants on the same footprint, simplifying hardware reuse. This page synthesizes distributor pricing, package-level drop-in alternatives within the Stratix III E family, and practical design notes that go beyond what the manufacturer datasheet alone provides - giving procurement and engineering teams a single reference for lifecycle, supply chain, and engineering decisions.

The 1152-FCBGA package exposes 744 user I/O balls with flip-chip BGA interconnect for high signal-integrity performance. The device integrates a programmable PowerPlay power management system with on-chip temperature-sensing diodes, allowing dynamic voltage and frequency scaling. Quartus II design software (with Qsys system integration tool) supports this part; newer Quartus Prime is not officially supported for Stratix III. The high logic count and DSP multiplier density make this part a strong choice when migrating ASIC or ASSP designs to programmable logic for prototyping or low-volume production. Typical applications include high-speed image processing, radar baseband, telecom protocol bridging, ASIC prototyping, high-end test and measurement equipment, and DSP-intensive data acquisition systems. Designers typically pair this FPGA with external DDR2/DDR3 memory, clock generators, and high-speed ADCs/DACs. When designing with this part, plan power delivery carefully: a 1152-ball FCBGA requires multiple voltage rails (core, I/O, PLL, auxiliary) with substantial decoupling. PCB designers must allocate dedicated layers for ground and power to maintain signal integrity at multi-hundred-megahertz toggle rates. Because the device is EOL per recent distributor notices, long-term availability should be confirmed before committing to new designs.

Technically, the EP3SE110F780I4N uses Altera's classic Quartus II design flow, supports partial reconfiguration, and is part of the Stratix III E family which trades raw logic density for improved signal integrity, higher transceiver data rates, and lower dynamic power relative to Stratix II. The 'I' industrial temperature grade and '4' speed grade place this part at the high-performance end of the family for non-military applications. Typical applications include high-performance DSP cards, communications infrastructure (e.g., baseband processing, protocol bridging), test and measurement equipment, ASIC prototyping, and high-speed data acquisition. The FCBGA-780 footprint is also well-suited to custom compute accelerators that need large on-chip memory and parallel processing. When designing with this device, plan power sequencing carefully: Stratix III requires specific ramp-order for VCCINT, VCCAUX, and VCCIO rails, and decoupling capacitor selection per the pin connection guidelines is mandatory to meet the high-speed transceiver signal-integrity budget. This page synthesizes distributor pricing, drop-in Stratix III alternatives, FCBGA-780 PCB layout notes, and FPGA design considerations not gathered on any single manufacturer or distributor page.

EP3SE260F1152C2

EP3SE260F1152C2 - 255K LE Stratix III E FPGA 1152-FCBGA | Intel

The Intel (Altera) EP3SE260F1152C2 is a high-density Stratix® III E Field Programmable Gate Array (FPGA) with 255,000 logic elements, 16,672,768 embedded memory bits, and 744 user I/Os in a 1152-ball FineLine Ball-Grid Array (FC-FBGA) package. It is built on a 65 nm low-power CMOS process and operates across an industrial-junction temperature range with a core voltage of 1.1 V. A Field Programmable Gate Array (FPGA) is a reconfigurable digital integrated circuit whose logic fabric, block RAM, DSP blocks, and routing can be programmed in the field by the designer to implement arbitrary digital functions, glue logic, accelerators, and high-speed serial interfaces. FPGAs sit hierarchically between ASICs (custom-fixed silicon) and general-purpose processors (software-defined), offering hardware-level parallelism without the NRE cost of an ASIC. The Stratix III E family is the "Enhanced" logic-rich variant of the Stratix III family, optimized for high logic density, generous embedded memory, and high I/O count for parallel data-path and backplane applications. Key features of the EP3SE260F1152C2 include 255K logic elements distributed across 10,200 Logic Array Blocks (LABs), 16,672,768 bits of embedded memory (about 2.04 Mbytes), support for multiple high-speed transceiver and external-memory-interface standards, and adaptive logic modules (ALMs) that pack combinational and registered logic into 8-input fracturable look-up tables. The device integrates dedicated DSP blocks, embedded multiplier blocks, and programmable I/O serdes that operate up to 1.25 Gbps per LVDS/HSIO channel. Architecturally, Stratix III E uses the Altera ALM as its basic logic cell - an 8-input adaptive LUT with two adder chains and two register outputs - which yields approximately 25% higher logic packing density than the older 4-input LUT-based architectures. The 1.1 V core, combined with programmable power-rail gating on each LAB row, lets the device trade frequency for power at fine granularity. Long-line routing and the MultiTrack interconnect are tuned for sustained Fmax above 300 MHz on typical pipelined designs and up to 600 MHz on small arithmetic paths. Typical applications include high-speed data-acquisition front-ends, parallel DSP for radar/SIGINT, telecommunications line cards with multiple SERDES lanes, ASIC prototyping, broadcast video processing, and protocol-bridging cards. With 744 user I/Os, the part is particularly suited to systems that need wide parallel buses (DDR2/DDR3 external memory, LVDS parallel video, or custom backplane interfaces) rather than just a few high-speed serial links. Designers using this device should generate bitstreams with the Quartus II design software (version 9.0 or later for full Stratix III E coverage) and pay attention to power-rail sequencing and decoupling on the FC-FBGA. The 'C2' speed grade and 1152-ball package imply commercial-temperature operation and a specific pinout/bank map that must be respected during PCB layout. This page synthesizes distributor pricing, drop-in and same-family alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers compare the EP3SE260F1152C2 against other Stratix III E devices and competitor FPGAs in the same FC-FBGA-1152 footprint.
