1ST085EN2F43E2LG

The 1ST085EN2F43E2LG is an Intel Stratix® 10 TX family FPGA in a 1760-ball FCBGA package designed for high-density, high-bandwidth programmable logic. It combines a large programmable fabric (850,000 logic elements) with 440 device I/Os and 71,303,168 bits of on-chip RAM to address demanding data-path, communication and compute-acceleration applications.

As an Extended-grade, surface-mount device with a supply voltage range of 820 mV to 880 mV and an operating temperature range of 0 °C to 100 °C, this Stratix 10 TX device targets systems that require high integration, advanced transceiver capability and substantial on-chip memory and logic resources.

Key Features

• High Logic Density — 850,000 logic elements for implementing complex digital designs and large-scale custom logic.
• On-chip Memory — 71,303,168 total RAM bits to support large buffering, packet processing, or data-intensive compute tasks.
• Rich I/O — 440 device I/Os to support wide parallel interfaces, multiple memory channels, and high-pin-count system integration.
• Advanced Transceiver Technology — Stratix 10 TX family features dual-mode transceivers supporting high-rate PAM4 and NRZ operation and hardened high-speed protocol IP (family-level feature).
• Core Architecture — Family HyperFlex® core architecture delivering significantly increased core performance over prior generations (family-level characteristic).
• Package & Mounting — 1760-ball BBGA / FCBGA package (1760-FBGA, 42.5 × 42.5 mm) in a surface-mount form factor for dense PCB integration.
• Power and Temperature — Supported supply range 820 mV–880 mV with an operating temperature range of 0 °C to 100 °C; Extended grade device for broader system applicability.
• Compliance — RoHS compliant.

Typical Applications

• Data Center Networking — High logic density and large on-chip RAM support packet processing, traffic management and network acceleration functions.
• Telecom & Optical Transport — Family transceiver capabilities and hardened protocol IP make this device suitable for high-speed serial links and backplane or module-level interconnects.
• High-Performance Compute Acceleration — Large logic and memory resources enable custom accelerators for signal processing, compression, or algorithm offload.
• PCI Express and Interconnect Systems — Use in systems requiring programmable fabric alongside hardened high-speed I/O and protocol blocks (family-level features).

Unique Advantages

• Large, Scalable Fabric: 850,000 logic elements provide capacity for complex SoC-class designs and increased on-board functionality.
