The EP4SE820H35I4N is an Intel STRATIX® IV E field-programmable gate array (FPGA) supplied in a 1152-ball BGA package. It delivers a large programmable fabric—813,050 logic elements—and rich on-chip memory resources, suitable for demanding industrial and high-performance system designs.

Designed for applications that require substantial logic capacity, dense I/O, and on-chip storage, this device couples the Stratix IV E device family architecture (including embedded memory, DSP resources, PLLs and advanced I/O features) with an industrial operating range and a compact FCBGA footprint.

Key Features

• Programmable Fabric: 813,050 logic elements for implementation of large custom logic, control and datapath functions.
• Embedded Memory: Approximately 34 Mbits of on-chip RAM to support buffering, packet processing, or large lookup-table storage.
• High I/O Density: 744 I/O pins to enable extensive external interfacing and parallel connectivity in dense system designs.
• Device Family Capabilities: Stratix IV E architecture features including DSP blocks, PLLs, clock networks, and high-speed transceiver/I/O features as documented in the device handbook.
• Industrial Grade: Specified for industrial applications with an operating temperature range of −40 °C to 100 °C.
• Power Supply Range: Core voltage specified from 870 mV to 930 mV to align with system power-rail planning.
• Package and Mounting: Surface-mount 1152-BBGA (FCBGA) package; supplier package listed as 1152-HBGA with 42.5 × 42.5 mm body for PCB layout and thermal considerations.
• RoHS Compliant: Conforms to RoHS requirements for regulated substance content.

Typical Applications

• High-speed data processing: Large logic capacity and substantial embedded memory make the device suitable for packet processing, protocol handling, and complex datapath implementations.
• Telecommunications infrastructure: Dense I/O and Stratix IV E family I/O/transceiver features support multi-channel interfaces and backbone signal handling.
• Industrial control and automation: Industrial temperature rating and abundant logic enable advanced motor control, real-time control algorithms, and machine-vision pre-processing.
• Signal processing and DSP: On-chip memory and the family’s DSP resources support filter engines, FFTs, and other compute-intensive algorithms.

Unique Advantages

• Large programmable capacity: 813,050 logic elements provide headroom for complex, integrated system designs and architecture consolidation.
• Integrated memory resources: Approximately 34 Mbits of embedded RAM reduce external memory dependency and simplify board-level BOM.
• High interface count: 744 I/O pins allow flexible routing and direct connectivity to multiple subsystems or high-pin-count peripherals.
• Industrial robustness: Specified −40 °C to 100 °C operation supports deployment in harsh or wide-temperature environments.
• System-level building blocks: Family-level features (PLLs, clock networks, DSP blocks, and high-speed I/O) streamline implementation of timing, DSP and interface requirements.
• RoHS compliance: Simplifies regulatory alignment for environmentally constrained markets.
