EP1S40F780C5N

The EP1S40F780C5N is a Stratix® FPGA from Intel featuring 41,250 logic elements, approximately 3.42 Mbits of embedded memory, and 615 I/O pins. It integrates Stratix architecture building blocks—logic array elements, on-chip memory, DSP interfaces, and advanced I/O—to support dense programmable logic and complex interfacing within a single device.

Packaged in a 780‑FBGA (29×29) surface-mount format and specified for commercial operation (0 °C to 85 °C), the device operates from a core supply range of 1.425 V to 1.575 V and complies with RoHS requirements.

Key Features

• Logic Capacity  41,250 logic elements provide substantial programmable fabric for implementing custom logic, control, and datapath functions.
• Embedded Memory  Approximately 3.42 Mbits of on-chip RAM (TriMatrix memory architecture referenced in device documentation) for packet buffers, FIFOs, and local storage.
• High I/O Count  615 I/O pins enable broad external interfacing and flexible system-level connectivity.
• Advanced I/O Structure  Device documentation references double-data-rate I/O support, differential on-chip termination, programmable drive strength, and other advanced I/O capabilities for high-speed interfacing.
• Clocking and PLLs  Stratix device handbook details global and hierarchical clocking, enhanced and fast PLLs, and dedicated clock networks for multi-clock and timing-critical designs.
• DSP & Multiplier Support  The family documentation includes DSP block interfaces and multiplier resources for arithmetic- and signal-processing tasks.
• Configuration & Testability  JTAG (IEEE 1149.1) boundary-scan support and embedded logic analyzer capabilities are described in the device handbook to aid development and debug.
• Package & Mounting  780‑BBGA, FCBGA package (780‑FBGA, 29×29) in surface-mount format suitable for compact system integration.
• Commercial Grade & Compliance  Rated for 0 °C to 85 °C operating temperature and RoHS compliant.
• Supply Voltage  Core supply range specified at 1.425 V to 1.575 V.

Typical Applications

• I/O‑intensive systems  Use the 615 available I/O pins and advanced I/O capabilities for complex external interfacing and multi-domain connectivity.
• Embedded memory buffering  Leverage approximately 3.42 Mbits of on-chip RAM for packet buffering, data alignment, and local storage in streaming applications.
• Signal processing and math engines  Use the documented DSP block interfaces and multiplier resources for custom arithmetic pipelines and real-time processing tasks.
• Multi-clock systems  Implement hierarchical clocking and PLL-based clock distribution for designs that require multiple clock domains and precise timing control.

Unique Advantages

• Substantial programmable fabric: 41,250 logic elements enable dense implementation of control, glue logic, and custom datapaths without external ASICs.
• Integrated memory resources: Approximately 3.42 Mbits of embedded RAM reduce dependency on external memory for many buffering and storage needs.
• Broad external interfacing: 615 I/O pins and documented advanced I/O features provide flexibility for diverse peripherals and bus interfaces.
• Comprehensive timing support: Documented PLLs and global/hierarchical clocking structures help manage complex timing and multi-rate designs.
• Development and test support: Standard JTAG boundary-scan and embedded logic analyzer capabilities aid bring-up and in-system debug.
• RoHS compliant, commercial-grade: Surface-mount 780‑FBGA package with commercial temperature rating simplifies procurement and integration for commercial products.
