EP1S25F780C6N

The EP1S25F780C6N is a Stratix® FPGA from Intel designed to deliver a balance of programmable logic, on-chip memory, and extensive I/O for commercial embedded and system applications. The device implements the Stratix family architecture with logic array blocks, dedicated DSP/multiplier resources and advanced clocking features to support complex digital designs.

With 25,660 logic elements, approximately 1.9 Mbits of embedded RAM, and 597 user I/Os in a 780-ball FBGA (29×29) package, this FPGA targets high-density integration where on-chip resources and flexible configuration are key design drivers.

Key Features

• Core Logic 25,660 logic element cells provide a substantial programmable fabric for custom digital functions, state machines, and control logic.
• Embedded Memory Approximately 1.9 Mbits of on-chip RAM for packet buffers, FIFOs, and local data storage.
• I/O and Package 597 user I/Os in a 780-FBGA (29×29) package; surface-mount mounting supports compact board-level integration.
• Clocking and DSP Support Stratix family clock networks and dedicated multiplier/DSP block interfaces support synchronous designs and signal-processing functions, as described in the device handbook.
• Configuration and Test IEEE 1149.1 (JTAG) boundary-scan support, SignalTap II embedded logic analyzer, multiple configuration schemes and partial reconfiguration capabilities for development and in-system debug.
• Power and Operating Range Core voltage range of 1.425 V to 1.575 V; commercial operating temperature range 0 °C to 85 °C.
• Compliance RoHS compliant for environmentally conscious manufacturing.

Typical Applications

• Digital Signal Processing Use the device's multiplier and DSP block interfaces combined with on-chip RAM to implement filtering, transforms, and other high-throughput signal-processing blocks.
• Custom High‑Speed I/O Interfaces Leverage the high I/O count and Stratix I/O structure to implement parallel interfaces, protocol bridging, and custom transceiver logic.
• Embedded System Integration Consolidate glue logic, controllers, and memory buffers on a single FPGA for compact embedded platforms and subsystem controllers.
• Prototype and In-System Debug JTAG boundary-scan and SignalTap II support enable board-level testing and real-time visibility during development and validation.

Unique Advantages

• High Logic Density: 25,660 logic elements enable implementation of complex control and processing functions without excessive external glue logic.
• Substantial On‑Chip Memory: Approximately 1.9 Mbits of embedded RAM reduces reliance on external DRAM for many buffering and storage needs.
• Extensive I/O Count: 597 user I/Os in a compact 780-BBGA package provide flexible connectivity for multi-interface designs.
• Design and Debug Tooling: Built-in JTAG boundary-scan and SignalTap II embedded logic analyzer streamline bring-up and shorten debug cycles.
• Commercial Temperature Rating: Rated for 0 °C to 85 °C operation, suitable for general-purpose commercial electronics and systems.
