A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit based on a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. Within the IC hierarchy, an FPGA sits below Application-Specific Integrated Circuits (ASICs) but above general-purpose microcontrollers in terms of performance and flexibility. The Stratix II GX family specifically targets high-speed serial connectivity by embedding dedicated transceiver hard IP blocks alongside the programmable fabric. Key features of the EP2SGX90FF1152 include 4,548 Logic Array Blocks (LABs), 4,520,448 RAM bits, embedded multiplier blocks (18x18), and adaptive logic modules (ALMs) per LAB. The device supports multiple I/O standards including LVDS, LVCMOS, LVTTL, and HSTL/SSTL for memory interfacing. Transceivers operate up to 6.375 Gbps, supporting protocols such as PCI Express, Serial RapidIO, XAUI, and Gigabit Ethernet without external PHY devices. Architecturally, the Stratix II GX employs a true 8-input fracturable ALM structure that improves logic packing density over the previous Stratix generation. Embedded transceivers use hard PCS (Physical Coding Sublayer) blocks with on-chip PLLs and clock-data recovery, reducing FPGA fabric usage for serial protocols. The 1.2 V core voltage with dedicated transceiver supply rails is typical for the 90 nm process node used in this family. Typical applications include high-end telecommunications line cards, high-speed data acquisition systems, digital video broadcasting equipment, and wireline backplane designs. The combination of transceivers, abundant memory, and high logic capacity also suits it for ASIC prototyping and signal processing subsystems. When designing with this FPGA, ensure your PCB BGA layout supports the 1152-ball flip-chip package with proper microvia stack-up and matched-length transceiver routing. Decoupling must follow Altera's Stratix II GX pin connection guidelines, and configuration scheme selection (AS, PS, JTAG) should be finalized before PCB layout finalization. This page consolidates distributor pricing, drop-in same-package alternatives from the Stratix II GX family, and practical design considerations beyond the datasheet to help engineers select and source this mature FPGA for long-lifecycle designs.
EP2SGX90FF1152C3 - Stratix II GX FPGA 90K LE | Intel | Altera
The Altera EP2SGX90FF1152C3 is a high-density Stratix II GX FPGA built on a 90-nm process, integrating 90960 logic elements and 4,520,448 RAM bits in a 1152-ball fine-pitch BGA (FF1152) package. It combines a 4.5 Mb embedded memory, 252 18x18 multipliers, and 4 enhanced PLLs with 16 global clock networks. The 'C3' speed grade and 'F' package prefix indicate a 1152-pin flip-chip BGA suitable for high-I/O-count designs. A Field Programmable Gate Array (FPGA) is a programmable semiconductor whose logic fabric, routing, and I/O can be reconfigured after manufacturing. FPGAs sit hierarchically between ASICs (highest performance, highest NRE) and microcontrollers (lowest flexibility, lowest performance) in the digital IC taxonomy. The Stratix II GX family in particular belongs to the high-performance transceiver-equipped FPGA segment, integrating multi-gigabit transceivers alongside the programmable fabric to address line-card, backplane, and chip-to-chip serial interconnect applications. Key features of the EP2SGX90FF1152C3 include 4.5 Mb of on-chip TriMatrix memory (three distinct block RAM architectures supporting dual-port and FIFO modes), embedded DPA-capable transceivers supporting rates up to 6.375 Gbps, 4 enhanced PLLs plus 8 fast PLLs, and 558 maximum user I/O pins. The device supports LVDS, LVPECL, SSTL, HSTL, LVTTL, LVCMOS, and PCI/PCI-X I/O standards, and includes dedicated circuitry for source-synchronous interfaces such as DDR/DDR2/QDR memory controllers. Architecturally, the Stratix II GX uses Altera's adaptive logic module (ALM) structure - an 8-input fracturable LUT that can implement any 6-input LUT function plus extra logic, allowing finer-grained logic packing than earlier Stratix families. Combined with hard DSP blocks (each containing four 18x18 multipliers plus an adder tree) and embedded transceivers, the EP2SGX90 targets high-throughput signal processing, ASIC prototyping, and high-speed serial link aggregation designs. Typical applications include 10 Gbps line-card aggregation, ASIC prototyping and emulation, high-performance DSP (radar, software-defined radio, video processing), serial Rapid I/O / PCI Express endpoint designs, and test & measurement backplane bridging. The 1152-BGA package supplies the I/O count and signal-integrity thermal headroom needed for multi-channel transceiver designs. Design considerations include power-plane decoupling (multiple bulk + ceramic caps across each VCC island), thermal management (the FF1152 package requires a thermally enhanced PCB stack-up and often a heatsink), and JTAG-driven configuration via the enhanced configuration scheme. Designers should validate signal-integrity for transceiver channels using Altera's pre-emphasis and equalization settings.

EP2SGX90FF1508 - 90,960 Cells FPGA | Altera | High-Speed Systems
Altera EP2SGX90FF1508 is a high-density Stratix II GX field-programmable gate array with 90,960 logic elements, 650 user I/O, and 4,520,448 RAM bits in a 1508-ball FCBGA package. The supplied source data identifies a 1.2 V supply and a listed Arrow frequency of 816.9 MHz, while Ampheo lists a related speed-grade listing at 717 MHz. The exact configuration suffix and the governing ordering-code table must therefore be checked before treating either number as a guaranteed operating limit. EP2SGX90FF1508 is intended for complex, high-speed digital systems requiring substantial programmable logic, embedded memory, and dense I/O. A field-programmable gate array is a semiconductor device whose logic functions, interconnects, and I/O behavior can be programmed after manufacturing. Within the hierarchy, EP2SGX90FF1508 is a FPGA, then a programmable logic device, then an integrated circuit, and ultimately a configurable digital semiconductor. Unlike a fixed-function application-specific integrated circuit, an FPGA supports design changes without a new mask set. Its configurable architecture is useful when interface standards, protocol processing, timing requirements, or product variants evolve. The principal resources are 90,960 logic elements and 4,520,448 RAM bits. DigiKey describes 650 user I/O for the EP2SGX90FF1508C3N ordering variant, and Mouser describes 4,548 LABs. These resources allow parallel datapaths, memory-intensive packet processing, and multiple interface controllers to coexist. The 1508-ball FCBGA package supports a large pin count on a compact BGA footprint, but demands controlled impedance, high-quality multilayer routing, and careful power delivery. The supplied Arrow listing states 1.2 V, 816.9 MHz, and 90,960 cells for the EP2SGX90FF1508C3N. A related Ampheo listing gives 717 MHz for EP2SGX90FF1508C4N, showing why speed grade and ordering code matter. The target base MPN does not contain a visible speed-grade suffix in the provided text, so design decisions must use the exact ordered part and its manufacturer handbook. The device belongs to a high-speed family suited to demanding logic and memory configurations rather than low-cost control-only implementations. Typical applications include high-throughput communications equipment, network packet processing, and test or imaging systems with parallel I/O. For communications systems, the programmable fabric can implement protocol-specific datapaths while 650 listed I/O support numerous external connections. For test equipment, 90,960 logic elements can implement real-time processing, capture control, and high-speed interfaces. These examples depend on final pin assignments, transceiver capability, power integrity, and timing closure in the exact configuration. Designers should first resolve the complete ordering code and download the applicable Stratix II GX device documentation. Validate the intended 1.2 V rail, speed-grade timing, supported I/O standards, configuration scheme, clock resources, junction temperature, and exact 1508-ball pinout. BGA assembly requires appropriate via-in-pad or via construction, escape routing, solder-paste geometry, and package warpage controls. Use the exact ordering-code table rather than assigning a frequency solely from a related speed grade. This product page combines verified distributor facts, explicit uncertainty markers, application context, package constraints, and sourcing information. It distinguishes exact base-MPN facts from suffix-specific listings and does not infer a guaranteed frequency where the verified data conflicts. Engineers should use the page to frame procurement and architecture decisions, then confirm implementation against the official Intel or Altera documentation and the exact purchased MPN.
