EP4SGX70HF35I4

The EP4SGX70HF35I4 is a Stratix IV GX field programmable gate array (FPGA) in a 1152-BBGA FCBGA package, offered for industrial-grade applications. It combines a high-capacity logic fabric with on-chip memory and a large I/O count to support high-bandwidth data processing, protocol bridging, and system integration tasks.

Built on the Stratix IV GX family architecture, the device targets designs that require extensive logic resources, embedded memory, and numerous I/O while operating across a wide industrial temperature range and low-voltage core supply.

Key Features

• Logic Capacity — 72,600 logic elements enabling complex combinational and sequential logic implementations and large custom logic designs.
• Embedded Memory — Approximately 7.56 Mbits of on-chip RAM for buffering, look-up tables, and embedded data storage.
• I/O Resources — 488 user I/O pins to support dense peripheral connectivity and external interface routing.
• Package and Mounting — 1152-BBGA (FCBGA) package; supplier package listed as 1152-FBGA (35×35). Surface-mount mounting type suitable for standard PCB assembly flows.
• Core Voltage — Core supply range of 870 mV to 930 mV for board power design and regulator selection.
• Industrial Temperature Range — Guaranteed operation from −40 °C to 100 °C for deployment in industrial environments.
• Compliance — RoHS compliant.
• Stratix IV GX Family Capabilities (series-level) — Family documentation identifies high-speed transceiver features, DSP blocks, external memory interface support, and architecture features for high aggregate data bandwidth and wide protocol support.

Typical Applications

• High‑speed data interfaces — Use the Stratix IV GX architecture and abundant I/O to implement protocol bridging and high-throughput data routing.
• Digital signal processing — Large logic capacity and embedded memory support DSP pipelines, filtering, and real‑time processing tasks.
• External memory controller and buffer management — On‑chip RAM and I/O resources facilitate interfacing to external memory and managing high-bandwidth data streams.

Unique Advantages

• Substantial logic resources: 72,600 logic elements provide headroom for complex state machines, accelerators, and custom logic blocks.
• On‑chip memory for buffering: Approximately 7.56 Mbits of embedded RAM reduces dependence on external memory for many real‑time tasks.
• High I/O density: 488 I/O pins accommodate dense interface requirements and multiple parallel buses without extensive external multiplexing.
• Industrial operating range: Rated from −40 °C to 100 °C to meet thermal requirements of industrial deployments.
• Board-level compatibility: Surface-mount 1152-BBGA FCBGA package (1152-FBGA, 35×35) for standard SMT assembly and compact PCB layouts.
• Regulated low-voltage core: Defined core supply range (870 mV–930 mV) simplifies power-system design and regulator selection.
