EP2S15F672I4

The EP2S15F672I4 is a Stratix II family FPGA from Intel, built on the Stratix II architecture and documented in the Stratix II Device Handbook. This device provides a balanced combination of programmable logic, embedded memory, and I/O resources for industrial-grade applications.

With 15,600 logic elements and 780 logic array blocks, the device supports mid-density designs requiring flexible I/O, embedded RAM, and a compact BGA package. Key value propositions include configurable logic fabric, on-chip memory, and support for industrial operating conditions.

Key Features

• Logic Fabric — 15,600 logic elements organized across 780 logic array blocks (LABs) to implement custom digital functions and control logic.
• Embedded Memory — 419,328 bits of on-chip RAM (approximately 0.42 Mbits) for FIFOs, buffers, and small data stores close to logic.
• I/O Resources — 366 I/O pins to support multiple interfaces and parallel connectivity in compact designs.
• Package & Mounting — 672-BBGA package; supplier device package listed as 672-FBGA (27×27). Surface-mount mounting type for board-level assembly.
• Power — Core voltage supply range of 1.15 V to 1.25 V to match system power rails supporting the device core.
• Temperature & Grade — Industrial grade with an operating temperature range of −40 °C to 100 °C for deployments in demanding environments.
• Standards & Environmental — RoHS compliant to meet common environmental and regulatory requirements.
• Stratix II Architecture Features — Device family documentation highlights on-chip features such as PLLs and clock networks, TriMatrix memory, DSP blocks, JTAG boundary-scan and embedded logic analysis, and configurable I/O capabilities.

Typical Applications

• Industrial Control & Automation — Implement control logic, state machines, and I/O aggregation using the device’s industrial temperature rating and extensive I/O count.
• Signal Processing & DSP Acceleration — Leverage the Stratix II architecture’s DSP-oriented resources and on-chip memory for filtering, data formatting, and real-time processing tasks.
• External Memory Interfaces — Use the device’s I/O and TriMatrix memory features for building memory controllers and interfacing with external RAM.
• Bridge & Interface Logic — Deploy as protocol translators, bus bridges, or glue logic between heterogeneous subsystems using dense logic and plentiful I/Os.

Unique Advantages

• High logic density: 15,600 logic elements provide the capacity to implement complex finite-state machines, custom accelerators, and glue logic without external CPLDs.
• Balanced embedded memory: Approximately 0.42 Mbits of on-chip RAM reduce external memory dependencies for small buffers and FIFOs.
• Extensive I/O: 366 I/Os enable multi-channel interfaces and parallel buses while keeping the design in a single FPGA package.
• Industrial-grade robustness: −40 °C to 100 °C operating range and industrial grade classification support deployment in temperature-challenging environments.
• Compact BGA footprint: 672-ball BGA (27×27 supplier FBGA outline) saves PCB area while maintaining routing density for complex board designs.
• Documented Stratix II ecosystem: The Stratix II Device Handbook describes architecture elements such as PLLs, DSP blocks, and configuration/testing features that support system integration and validation.
