The EP4SE820H40C4N is a Stratix IV E field programmable gate array (FPGA) offered in a 1517-ball FCBGA package. It delivers a high on-chip logic capacity and a large embedded memory footprint targeted at high-density, high-bandwidth digital designs.

Designed for applications requiring extensive I/O and on-chip resources, this commercial-grade FPGA provides a balance of integration and performance with core voltage operation between 870 mV and 930 mV and an operating temperature range of 0 °C to 85 °C.

Key Features

• High logic capacity — 813,050 logic elements for complex, large-scale digital implementations and dense logic integration.
• Significant embedded memory — Approximately 34 Mbits of on-chip RAM to support buffering, frame storage, and local data processing.
• Extensive I/O — 976 general-purpose I/Os to accommodate broad interfacing needs and multi-channel connectivity.
• Stratix IV E architecture — Part of the Stratix IV E device family, with architecture-level features documented in the device handbook including embedded memory, DSP resources, clock networks, PLLs, and I/O capabilities.
• Package and mounting — 1517-BBGA (FCBGA) package; supplier device package listed as 1517-HBGA with 42.5 × 42.5 mm footprint; surface-mount device for PCB integration.
• Power and thermal — Core voltage supply range of 870 mV to 930 mV and commercial operating temperature range of 0 °C to 85 °C.
• Compliance — RoHS-compliant construction for environmental compliance in commercial applications.

Typical Applications

• High-density digital processing — Large logic capacity and substantial on-chip RAM make the device suitable for complex data-paths and custom processing pipelines.
• Multi-channel I/O systems — With 976 I/Os the FPGA can handle numerous parallel interfaces, sensor arrays, or multi-lane communication endpoints.
• High-bandwidth buffering and memory interfacing — Approximately 34 Mbits of embedded memory supports local buffering and intermediate storage for streaming or burst data flows.

Unique Advantages

• High integration density: 813,050 logic elements enable consolidation of multiple functions into a single device, reducing board-level complexity.
• Large on-chip memory: Approximately 34 Mbits of RAM reduces dependence on external memory for many buffering and caching tasks.
• Broad I/O capacity: 976 I/Os allow flexible signal partitioning and extensive peripheral connectivity without immediate need for external expanders.
• Compact, manufacturable package: 1517-ball FCBGA with surface-mount mounting supports automated assembly and a compact board footprint (supplier package dimension 42.5 × 42.5 mm).
• Commercial-grade operation: Specified for 0 °C to 85 °C operation and RoHS compliance for standard commercial deployments.
• Stratix IV E family support: Documented architecture features (memory, DSP blocks, clock networks, PLLs, and I/O capabilities) provide a clear technical foundation for design planning.
