EP1S40F780C8

The EP1S40F780C8 is a Stratix® field programmable gate array (FPGA) by Intel (Altera) delivered in a 780-ball FCBGA package. It provides a high-density programmable fabric with 41,250 logic elements and approximately 3.42 Mbits of embedded memory for complex digital designs.

With 615 user I/O pins, on-chip clocking and DSP resources described in the Stratix device handbook, and a 1.425 V–1.575 V core supply window, this FPGA targets designs that require dense logic, substantial embedded memory, and extensive external interfacing within commercial temperature ranges.

Key Features

• Logic Capacity  Provides 41,250 logic elements suitable for implementing complex state machines, datapaths, and custom logic functions.
• Embedded Memory  Approximately 3.42 Mbits of on-chip RAM to support buffers, FIFOs, and local storage for data-intensive functions.
• High I/O Count  615 user I/O pins enable dense external connectivity for multi-channel interfaces and parallel buses.
• Clocking and DSP Resources  Architecture details in the Stratix device handbook describe PLLs, clock networks, multiplier blocks, and DSP block interfaces for synchronous and arithmetic-intensive designs.
• Configuration & Debug  Supports industry-standard configuration and testing features documented in the Stratix handbook, including JTAG boundary-scan and SignalTap II embedded logic analysis, plus multiple configuration schemes and partial reconfiguration options.
• Power Supply  Core voltage specified between 1.425 V and 1.575 V for predictable power planning and supply design.
• Package & Mounting  780-ball BGA (FCBGA) package, supplier device package listed as 780-FBGA (29×29); surface-mount mounting for board-level integration.
• Environmental & Grade  Commercial-grade device with an operating temperature range of 0 °C to 85 °C and RoHS compliance.

Typical Applications

• High-density digital processing  Implement complex finite-state machines and custom datapaths using the 41,250 logic elements and on-chip RAM.
• Multi-channel I/O systems  Leverage 615 I/O pins for dense parallel interfaces, protocol bridging, and multi-lane capture/drive applications.
• Embedded memory buffering  Use approximately 3.42 Mbits of embedded memory for packet buffering, frame storage, and local data manipulation.
• Timing- and clock-sensitive designs  Employ the device’s documented PLLs and clock networks to manage complex clock domains and synchronous data paths.

Unique Advantages

• High integration density: Consolidates substantial logic and memory on a single device to reduce board-level component count and simplify system architecture.
• Extensive external connectivity: 615 I/O pins allow high-pin-count interfaces without external multiplexing, supporting richer system integration.
• Flexible configuration and debug: Built-in support for JTAG boundary-scan and SignalTap II (per the Stratix handbook) accelerates bring-up and in-system debugging.
• Documented architecture and tooling: Coverage in the Stratix device handbook details architecture blocks such as TriMatrix memory, multiplier blocks, PLLs, and configuration modes to aid design planning.
• Commercial-grade and RoHS compliant: Designed for commercial temperature operation (0 °C to 85 °C) and compliant with RoHS requirements for global manufacturability.
