The EP1SGX40DF1020C5N is a Stratix® GX family field programmable gate array (FPGA) IC offering a high-performance, scalable logic array combined with advanced high-speed serial transceiver capabilities. This commercial-grade, surface-mount device delivers 41,250 logic elements, approximately 3.4 Mbits of embedded RAM, and 624 I/O pins in a 1020-ball BGA footprint.

Designed for high-speed backplane interfaces, chip-to-chip links and communications protocol bridging, this device pairs a 1.5‑V logic architecture with configurable transceiver features and rich on-chip resources for systems that require integrated serial bandwidth and dense logic integration.

Key Features

• Core logic — 41,250 logic elements (LEs) implemented in a 1.5‑V logic array, delivering scalable logic density for complex FPGA designs.
• Embedded memory — Approximately 3.4 Mbits of on-chip RAM with TriMatrix™ memory architecture that supports multiple RAM block sizes for true dual-port memory and FIFO implementations.
• High-speed serial transceivers — Family-level support for full-duplex transceiver operation from 500 Mbps to 3.1875 Gbps with clock data recovery (CDR), programmable VOD, pre-emphasis and equalization, and individual channel power-down control.
• Protocol and SERDES support — Transceiver features and IP support for XAUI, Gigabit Ethernet, SONET/SDH and compatibility with PCI Express, SMPTE 292M, Fibre Channel and Serial RapidIO standards (as provided at the family level).
• I/O and interface flexibility — 624 device I/O pins with support for numerous single-ended and differential I/O standards, including LVDS, LVPECL and 3.3‑V PCML on reference clocks and receiver inputs; source-synchronous differential I/O for high-speed interfaces.
• DSP and performance blocks — Dedicated high-speed DSP blocks for multipliers and MAC/FIR implementations (specified faster than 300 MHz), enabling signal processing and arithmetic acceleration on-chip.
• Clocking and PLLs — Up to eight general-purpose PLLs per device region (four enhanced PLLs and four fast PLLs) offering spread-spectrum, programmable bandwidth, clock switchover and real-time reconfiguration.
• Package, power and thermal — 1020‑BBGA / 1020‑FBGA (33×33) package, surface-mount mounting type, supply voltage range 1.425 V to 1.575 V, and commercial operating temperature range 0 °C to 85 °C.
• Reliability and test — Built-in self-test (BIST), pattern detection/word alignment, 8B/10B encoding/decoding and hot insertion/removal protection circuitry available at the family feature level.
• RoHS compliant — Device is RoHS status compliant.

Typical Applications

• High-speed backplane interfaces — Use the integrated transceivers and dense logic to implement multi-gigabit backplane links and protocol bridging for networking equipment.
• Chip-to-chip communication — Leverage SERDES and CDR features for reliable, high-bandwidth chip-to-chip serial links in complex system boards.
• Communications protocol bridging — Implement protocol converters and aggregation functions using abundant logic, embedded memory and transceiver features.
• High-speed I/O subsystems — Build source-synchronous and differential I/O interfaces for packet processing, storage controllers or custom high-throughput peripherals.

Unique Advantages

• Integrated serial bandwidth and logic density: Combines multi-gigabit transceiver capabilities with 41,250 logic elements to consolidate functions that would otherwise require multiple chips.
• Significant embedded memory: Approximately 3.4 Mbits of on-chip RAM enables large buffers, FIFOs and data-path storage without external memory for many applications.
• Flexible transceiver tuning: Programmable VOD, pre-emphasis and equalization let designers optimize signal integrity for board-level and channel conditions.
• Dedicated DSP resources: High-speed DSP blocks (multipliers and MACs) accelerate signal processing tasks and offload compute from general logic.
• Comprehensive clock management: Multiple PLLs with real-time reconfiguration support complex clocking schemes and spread-spectrum requirements.
• Board-level integration ready: 1020‑BBGA package and surface-mount mounting make the device suitable for compact, high-density PCB designs.
