EP4SGX360NF45C4N

The EP4SGX360NF45C4N is a Stratix IV GX field-programmable gate array (FPGA) IC designed for high-density, high-bandwidth applications. It integrates a large programmable fabric and on-chip resources to support complex logic, embedded memory, and high-speed I/O.

Targeted at designs that require substantial logic capacity, extensive I/O, and advanced transceiver and clocking features, this commercial-grade device delivers integration and configurability for systems-level functions such as high-speed serial links, external memory interfaces, and DSP-centric processing.

Key Features

• Large logic capacity — 353,600 logic elements provide a sizable programmable fabric for complex system implementations.
• Embedded memory — Approximately 23.1 Mbits of on-chip RAM to support buffering, FIFOs, and memory-centric logic.
• High I/O count — 920 general-purpose I/Os to accommodate wide parallel interfaces, numerous peripherals, and board-level connectivity.
• High-speed transceiver and I/O features — Device handbook references high-speed transceiver features and high-speed differential I/O (including DPA and Soft-CDR) for serial protocol support and signal integrity.
• Clocking and DSP resources — Architecture-level features include clock networks, PLLs, and DSP blocks as noted in the Stratix IV device handbook for timing and signal processing tasks.
• Power and voltage — Core voltage supply range specified at 870 mV to 930 mV for device operation.
• Package and mounting — 1932-BBGA (FCBGA) package, supplier package 1932-FBGA (45×45), surface-mount mounting type for compact board integration.
• Commercial operating range — Rated for 0 °C to 85 °C operation.
• RoHS compliant — Device is RoHS compliant.

Typical Applications

• High-speed serial communications — Leverages the device's transceiver features and high-speed differential I/O for protocol implementations and link aggregation.
• External memory interface controllers — Ample logic and embedded RAM enable complex memory controllers and buffering between processors and external memory devices.
• DSP and signal processing — Large logic fabric, DSP resources, and on-chip RAM support algorithm acceleration and real-time processing tasks.
• Embedded system integration — High I/O count and comprehensive clocking resources allow integration of multiple peripherals and subsystem control on a single FPGA.

Unique Advantages

• High-density programmable fabric: 353,600 logic elements allow large, integrated designs without partitioning across multiple devices.
• Substantial on-chip memory: Approximately 23.1 Mbits of embedded RAM reduces external memory dependency for many buffering and LUT-based applications.
• Extensive board connectivity: 920 I/Os accommodate wide bus interfaces, parallel peripherals, and flexible board routing options.
• Advanced I/O and transceiver support: Included high-speed differential I/O and transceiver features support serial protocols and improved signal integrity techniques.
• Compact, production-ready package: 1932-BBGA (FCBGA) surface-mount package supports high-density PCB layouts and automated assembly.
• Defined commercial specifications: Documented operating temperature and core voltage ranges support predictable system design and procurement.
