EP1SGX40DF1020C6N

The EP1SGX40DF1020C6N is a Stratix GX family FPGA designed for high-performance, logic-dense applications. Built on the Stratix GX architecture, the device combines a large logic array with the family’s high-speed serial transceiver capabilities to address high-speed backplane, chip-to-chip, and communications protocol-bridging applications.

This commercial-grade, surface-mount FPGA offers substantial on-chip resources and I/O capacity, making it suitable for designs that require significant logic, embedded memory, and flexible I/O in a 1020-ball BGA package.

Key Features

• Logic Capacity — 41,250 logic elements (LEs) to implement complex digital logic and control functions.
• Embedded Memory — Approximately 3.42 Mbits of on-chip RAM for FIFOs, buffers, and embedded data storage without reducing logic resources.
• I/O Density — 624 I/O pins providing broad interfacing capability for parallel buses, high-speed interfaces, and system connectivity.
• High‑Speed Transceiver Technology (family) — Stratix GX family transceiver features include CDR-equipped serial channels supporting up to 3.1875 Gbps, programmable pre-emphasis/equalization, and support for common serial protocols as documented for the family.
• DSP and Clock Resources — Family-level support for dedicated DSP blocks and multiple PLLs to implement high-speed arithmetic and flexible clocking (see family documentation for details).
• Package and Mounting — 1020-BBGA package (supplier device package: 1020-FBGA, 33×33), surface-mount mounting for compact board-level integration.
• Power and Supply — Nominal core supply range of 1.425 V to 1.575 V to match system power rails.
• Commercial Temperature Range — Rated for 0 °C to 85 °C ambient operation.
• Standards & Tools (family) — Family documentation references support for protocol megafunctions and Quartus II software features such as automatic transceiver channel power-down for reduced power during non-operation.
• RoHS Compliant — Meets RoHS environmental compliance requirements.

Typical Applications

• High‑speed backplane interfaces — Implement protocol bridging and wide parallel or serial interfaces where large logic capacity and many I/Os are required.
• Chip‑to‑chip connectivity — Use the device’s logic density and family transceiver features for board-level and card-to-card data paths.
• Communications protocol bridging — Implement protocol conversion and packet processing functions leveraging embedded memory and DSP resources.
• High‑performance embedded systems — Deploy as a central FPGA for control, data aggregation, and custom logic in commercial equipment operating within the specified temperature range.

Unique Advantages

• High logic density: 41,250 logic elements enable large, consolidated designs and reduce the need for multiple devices.
• Significant on‑chip memory: Approximately 3.42 Mbits of embedded RAM supports deep buffering and complex state machines without external memory.
• Large I/O complement: 624 I/Os provide flexibility for parallel buses, external memory interfaces, and multiple peripheral connections.
• Scalable transceiver capability (family): Stratix GX family transceivers support multi‑Gbps links and protocol features that simplify high-speed serial design tasks.
• Compact board footprint: 1020-BBGA / 1020-FBGA (33×33) package provides a high-resource FPGA in a space-saving BGA format.
• Regulated supply range and commercial rating: Defined core voltage (1.425–1.575 V) and 0 °C to 85 °C operating range simplify system power and thermal planning for commercial applications.
