EP1S20B672C6

The EP1S20B672C6 is a Stratix® family field programmable gate array (FPGA) from Intel (Altera) packaged in a 672-ball BGA (35 × 35 mm). It provides a mid‑range programmable logic platform combining approximately 18,460 logic elements, roughly 1.67 Mbits of embedded memory, and a high I/O count for complex digital designs.

This device is suited to commercial‑grade applications that require dense logic integration, substantial on‑chip RAM, and flexible I/O. Key value propositions include a high logic element count, substantial embedded memory capacity, and a 426-pin I/O footprint in a compact surface‑mount BGA package.

Key Features

• Programmable Logic Capacity – Approximately 18,460 logic elements provide a substantial resource pool for implementing custom logic, state machines, and datapaths.
• Embedded Memory – Approximately 1.67 Mbits of on‑chip RAM supports buffers, FIFOs, and local storage for high‑performance logic functions.
• I/O Density – 426 user I/O pins enable extensive external interfacing and support complex multi‑lane or multi‑peripheral designs.
• Package & Mounting – 672‑BBGA (672‑BGA, 35 × 35 mm) surface‑mount package offers a high‑pin‑count, compact footprint for board integration.
• Power Supply Range – Core voltage supply specified at 1.425 V to 1.575 V for deterministic power planning and board design.
• Commercial Temperature Range – Rated for 0 °C to 85 °C operation, suitable for commercial‑grade systems and environments.
• Architecture & Tooling (Series-Level) – The Stratix device handbook describes architecture elements such as logic array blocks, TriMatrix memory, PLLs and clock networks, configurable I/O structures, and configuration/testing support (JTAG, SignalTap II), which are part of the Stratix family design philosophy.
• Regulatory Compliance – RoHS compliant.

Typical Applications

• High‑density custom logic – Implement state machines, protocol engines, and application‑specific accelerators that benefit from a large pool of logic elements and embedded memory.
• I/O‑intensive systems – Use the 426 I/O pins for multi‑lane interfaces, parallel buses, or dense sensor and peripheral interconnects.
• Embedded buffering and data staging – Leverage approximately 1.67 Mbits of on‑chip RAM for FIFOs, packet buffers, and temporary data storage in throughput‑sensitive designs.

Unique Advantages

• High logic density: The device’s ~18,460 logic elements allow significant functionality to be integrated on a single FPGA, reducing external ASIC/FPGA counts.
• Substantial on‑chip memory: Approximately 1.67 Mbits of embedded RAM supports local data processing without relying solely on external memory, simplifying board design.
• Extensive I/O resources: 426 user I/O pins enable flexible system partitioning and direct interfacing to multiple peripherals or high‑pin‑count connectors.
• Compact high‑pin package: The 672‑BBGA (35 × 35 mm) provides a high I/O and logic density in a controlled, surface‑mount footprint suited to compact commercial designs.
• Commercial operating range: Specified 0 °C to 85 °C operation aligns with many commercial applications and environments.
• RoHS compliant: Meets common lead‑free assembly and environmental sourcing requirements.
