EP1SGX25DF1020C5

The EP1SGX25DF1020C5 is a Stratix GX family FPGA that combines a scalable, high-performance logic array with transceiver-capable I/O optimized for high-speed communications. This surface-mount, commercial-grade device targets applications requiring dense logic, substantial embedded memory, and extensive I/O resources.

Typical use cases include high-speed backplane interfaces, chip-to-chip connectivity, and communications protocol bridging where integration, predictable power rails, and a compact 1020-BBGA package are important design considerations.

Key Features

• Logic Capacity — 25,660 logic elements (LEs) to implement complex digital logic and control functions.
• Embedded Memory — Approximately 1.945 Mbits of on-chip RAM for FIFOs, buffers, and state storage.
• I/O Density — 607 I/O pins to support wide parallel interfaces and mixed signalling ensembles.
• Transceiver-enabled Architecture (family-level) — Built on the Stratix GX family architecture which includes high-speed serial transceiver technology and SERDES capability suitable for multi-gigabit links and communications protocols.
• Power Supply — Core supply range of 1.425 V to 1.575 V for compatibility with Stratix GX core voltage requirements.
• Package & Mounting — 1020-ball fine-pitch BGA (33 × 33 FBGA footprint); surface-mount mounting for compact board-level integration.
• Operating Temperature — Commercial-grade rating with 0 °C to 85 °C operating range.
• Regulatory — RoHS-compliant construction.

Typical Applications

• High-speed backplane interfaces — Implement protocol bridging and packet routing functions where dense logic and high I/O counts are required.
• Chip-to-chip connectivity — Supporting protocol adaptation and SERDES-based links between ASICs, processors, and daughtercards.
• Communications equipment — Enabling interface conversions and timing-critical datapath processing for network infrastructure modules.
• Multi‑protocol gateway modules — Leverage embedded memory and logic density to buffer, align, and translate between serial and parallel interfaces.

Unique Advantages

• High logic density: 25,660 logic elements accommodate substantial custom logic, DSP control, and protocol engines without external glue logic.
• Substantial on-chip RAM: Approximately 1.945 Mbits of embedded memory reduces external memory dependency for buffering and packet processing.
• Extensive I/O: 607 I/O pins provide flexibility for wide parallel buses, high pin-count peripherals, and mezzanine connections.
• Compact BGA footprint: 1020-ball BBGA package delivers a high-pin-count solution in a space-efficient package suitable for dense PCBs.
• Commercial temperature range: Rated 0 °C to 85 °C for applications targeting standard commercial environments.
• RoHS-compliant: Environmentally compliant construction simplifies regulatory handling and product integration.
